The calling of step S302 can be initiated by user 104 or user 110.During calling, user 104 carrys out real-time Communication for Power with 110 by sending the data stream comprising the data relevant with calling with reception.Such as, relevant with calling data can include that be output by the far-end in calling, encoded audio or video data.Data stream is known communication protocol according to the client software for performing on user terminal 102 and 110 and is established and implements, so that call data can be properly transferred during calling and receive.
In step S304 (this step is performed while implementing calling), communication system 100 is set up the single media sharing session between user terminal 102 and 110.Before media sharing session can be established, user terminal 102 first checks for whether user terminal 110 supports media sharing session.This can inquire about the media sharing capabilities of user terminal 110 implement by inquiry is sent to user terminal 110 from user terminal 102.If user terminal 110 supports media sharing session really, then the reply to inquiry is sent to user terminal 102 from user terminal 110.Receive reply in response on user terminal 102, the user interface of the client performed on user terminal 102 enables media sharing option (such as, button or feature).Such as, button as the part of the catalog system in the user interface of user terminal 102 or can be displayed in the user interface of user terminal 102 as the most visible button during calling, and is similar to how mute button can be displayed in user interface for making described calling quiet.In order to set up media sharing session, the user interface of the client that user 104 performs on user terminal 102 selects media sharing option.Such as, user 104 can such as use the display 204 of user terminal 102 touch screen or such as pressing be linked on the remote controller of user terminal 102 dedicated button press or click on the button on user terminal 102, user terminal 102 itself can be such as Set Top Box.The data relevant with media sharing session use media to share agreement and transmit, and these media are shared agreement and are different from the agreement that the transmission call data relevant with the calling implemented in step s 302 are used.By this way, if user terminal 110 does not support that media sharing session and nonrecognition media share agreement, then user terminal 110 by do not reply send from user terminal 102 support the relevant inquiry of the ability of media sharing session with user terminal 110.If being not received by the reply to inquiry in during the scheduled time that user terminal 102 is after sending inquiry (such as, within sending a second of inquiry), then user terminal 102 may determine that user terminal 110 does not support media sharing session, in this case, the user interface of client user terminal 102 performed does not enables media sharing option.Therefore, user 104 only can initiate media sharing session when user terminal 110 can support media sharing session.Even if not supporting media sharing session on user terminal 110, the observability of media sharing feature can also be provided for the button initiating media sharing session by display in the user interface of user terminal 102 described above, but this button should be prohibited in some way, make it invalid the most in some way, so that user 104 can not select this button.
When media sharing session is established, media sharing session is certified based on the calling implemented between user terminal 102 and 110.It is, because calling is implemented between user terminal 102 and 110, it is not necessary to perform single authentication check process (being similar to perform the process of authenticated calling) and determine that media sharing session is certified.
When user 104 selects media sharing option to initiate media sharing session from the user interface of user terminal 102, the request for media sharing session is sent to user terminal 110.Receiving request in response on user terminal 110, the request for media sharing session (will be similar to for accepting the request of calling by the user interface how being displayed on user terminal 110) in the user interface being displayed on user terminal 110.Then user 112 can accept or refuse media sharing session.When user terminal 102 is just waiting the response for described request, the user interface of user terminal 102 is provided an instruction and is just waiting the response for described request to user 104 indicating user terminal 102.If user 112 refuses media sharing session, this is indicated in the user interface of user terminal 102.If user 112 accepts media sharing session, then media sharing session is established.Therefore, in order to set up media sharing session, user 104 selects the option for setting up media sharing session in the user interface of user terminal 102, and user 112 accepts media sharing session and user terminal 102 and 110 runs the user interface for media sharing session.User interface for media sharing session can be included in the part of the user interface for calling.Such as, when calling is video call, the layout in the user interface of video call can include the private part of the image received in media sharing session for display from user terminal 102.This private part of user interface can be established in response to the foundation of media sharing session.
From user terminal 102 be sent to user terminal 110, for determining whether user terminal 110 supports that the inquiry of media sharing session can be sent in response to the initiation of the calling implemented in step s 302.By this way, no matter when user terminal 102 implements calling, for setting up with other user of this calling according to other user of this calling, whether the option of media sharing session will support that media sharing session is presented to user 104 in the user interface of user terminal 102.
From user terminal 102 be sent to user terminal 110, for determining whether user terminal 110 supports that the inquiry of media sharing session can be sent rather than sent in response to the initiation of the calling between user terminal 102 and 110 frequently.User terminal 110 should be in response to such inquiry, even if described inquiry is to be received currently without the user terminal of the calling implemented with it from user terminal 110.
Once media sharing session has been set up, then, in step S306, media data is passed to user terminal 110 from user terminal 102 in media sharing session.Media data is shared agreement according to the media of media sharing session and is passed.The media data being passed is exported to user 112 via the user interface of user terminal 110.Such as, in the case of media data includes image, image is displayed to user 112 on the display of user terminal 110.When the media data being passed is received from user terminal 102 in media sharing session, the media data being passed can be exported on user terminal 110 automatically.
Calling and media sharing session carry out the single data stream transmitted between user terminal 102 and 110 for (i) according to the call data of hello protocol and (ii) according to the media data of media sharing session agreement simultaneously.
Media data can be sent to user terminal 110 from user terminal 102 by network 108 in media sharing session as packets of data.Packet is formed according to the agreement of media sharing session.Each packet can include a part for media data, and wherein user terminal 110 receives multiple packet and combines the data from these packets to be exported by media to the user 112 on the user terminal 110 in media sharing session.Such as, each packet can include a number of data, such as 16KB or 64KB.In one example, former data are Base64 codings.The data transfer size of packet can be included as the prefix of the data in packet itself.Data transmission size should be size rather than the size of initial data itself of the data after Base64 conversion.Preferably, the media data of media sharing session uses and is applied to apply (app2app) stream to be passed, and it is that ratio uses datagram to send the communication means that data are more reliable.Datagram is used in the different masses of data send data, and does not require to confirm the reception of data.This is contrary with sending data stream, and in sending data stream, data are sent continuously on stream and the reception of data is guaranteed.This makes to send data flow ratio and sends datagram more reliable.
Some in message transmission between user terminal 102 and 110 are (such as, its beginning being used to signalisation media sharing session and end and be used to send inquiry and reply the ability supporting media sharing session about user terminal 110, etc.) can be sent in the form of packets, compared to packet, described packet has the data of varying number.These packets can be less than packet and can such as have 64 bytes.The agreement of media sharing session is also observed in these packets.
During media sharing session, user interface on user terminal 102 provides the ability of browsing media data for user 104, described media data such as photo (it can be stored in the memorizer 226 of user terminal 102), if and user terminal 110 supports media sharing session, some or all in media data are sent to when needing in media sharing session user terminal 110, and meanwhile video (or audio frequency) calling between two user terminals 102 and 110 proceeds.
In example described above, the client computer that user terminal 102 is the main frame of media sharing session and user terminal 110 is media sharing session.User terminal 102 is responsible for media sharing session and can control which fragment of media data and be passed to user terminal 110 during media sharing session.On the contrary, user terminal 110 exports media data (such as, its display photos), and described media data is as and is passed when it is received from user terminal 102 in media sharing session.Especially, which fragment during user terminal 110 may not control media data (such as, photo) is watched during media sharing session.
For interoperability and for Information Security and privacy of user, some little restrictions can be placed in the embodiment of media sharing session.Such as, in one or more embodiments, in media sharing session, transfer to the dish (that is, memorizer) that the media data of user terminal 110 should not be stored on the second user terminal 110.Media sharing session allows the shared output (such as, the shared viewing of image) between media data user in communication system 100, keeps the option that can be used for user terminal 110 (that is, the client computer of media sharing session) simple simultaneously.In addition, user terminal 102 is (i.e., the main frame of media sharing session) on user terminal 110, the output of media data can be controlled, and can control it make once only have media data a fragment (such as, one file of media data) can be output on user terminal 110, wherein, user terminal 102 controls to be watched on which fragment of media data user terminal 110 in media sharing session.By the media data being not stored in being passed in media sharing session on user terminal 110, the storage device on user terminal 110 and the expense in terms of memorizer in embodiment can be reduced.Because the media data of transmission is not permanently stored on user terminal 110 (such as in media sharing session, terminate do not have media data to be stored on user terminal 110 afterwards in media sharing session), then user terminal 102 is not required to that all files (such as, photo files) of media data is assigned to user terminal 110 to show media data to user 112.As described above, the media data being passed can include multiple file, and in certain embodiments, the file that is not more than in each described file is stored on user terminal 110 in media sharing session.Such as, when in file is stored on user terminal 110 in media sharing session, then in media sharing session, receiving of next file will cause the file being currently stored on user terminal 110 will to be deleted so that newly received file can be stored on user terminal 110 from user terminal 110, and need not be stored in media sharing session on user terminal 110 by more than one file in file every time.Additionally, the media data being passed can be stored in the data storage on user terminal 110, it is exclusively used in the data of storage media sharing session and is different from the main storage of user terminal 110.
In order to select to transfer to the media data file of user terminal 110 in media sharing session, user 104 can be via file tree structure or via the file of patterned navigation scheme upload media data on user terminal 102.In the film strip view (film strip view) that one or more in media data file can be selected by user 104 and then selected media data file can be displayed on user terminal 102.Film-strip can be scrolled (left and right or upper and lower).User 104 then can be such as by selecting media data file (such as from film-strip click media data file, photo) in one or more and selected media data file then can be sent to user terminal 110 in media sharing session.
Main frame (that is, user terminal 102) in media sharing session has the form of conversion media data to adapt to the ability of media sharing session, and in the sense that, it is " intelligent " main frame.Such as, the ability of the client that the form of media data can be changed to adapt to media sharing session client computer (user terminal 110).The conversion of media data can include scaling and/or compression so that the size (such as, the quantity of the bit of media data) of media data is reduced (such as, by reducing the resolution of image) to adapt to the requirement of user terminal 110.As an example, when media data is picture data, user terminal 102 provides the support for multiple picture format (such as, jpeg, bitmap, png ...) and offer to convert the image into the ability of the form that user terminal 110 is supported.In a simply example, before picture data is sent in media sharing session user terminal 110, all of picture data is converted into jpeg format.As described above, when media sharing session is established, user terminal 102 sends a query to user terminal 110 to determine whether user terminal 110 supports media sharing session, and as response, user terminal 110 sends to user terminal 102 and replys, and described reply may indicate that user terminal 110 supports media sharing session really.Be included in reply be user terminal 110, for the instruction of requirement of receiving media data in media sharing session.Such as, report may indicate that: (i) specific form is (such as, JPEG for view data), it carrys out receiving media data in that format, and/or (ii) user terminal 110, the memorizer of the media data relevant with media sharing session is limited.By this way, user terminal 102 is able to determine how to change media data (such as, use which kind of form and whether scale media data) for being transferred to user terminal 110 in media sharing session.This allows the client of media sharing session (such as, on user terminal 110) embodiment be simplified, because they only require a kind of specific format of support (such as, jpeg format) and they can should be converted into that specific format for being transferred to user terminal 110 in media sharing session to other user terminal instruction media data.Can also be enhanced the transfer time in media sharing session for media data, because the quantity of the media data shifted in media sharing session can be reduced due to the scaling of media data.
User terminal 102 can use adjustment size algorithm for scaling for the media data of transmission in media sharing session.Such as, when media data is view data, user terminal 102 can select the resolution less than or equal to original image (not having to amplify), and the target of the friendly resolution of the maximum fine definition (HD) of setting (such as, 480 pixel height can be used as acquiescence) is limited according to the memorizer of the user terminal 110 reported.In certain embodiments, the user 104 of user terminal 102 can have the option of the maximum zoom ratio changing the media data transmitted in media sharing session.This can complete via the user interface of user terminal 102.
Arbitrary participant in media sharing session can terminate media sharing session.In order to terminate media sharing session, user 104 such as can select " media sharing session terminates " button on user terminal 102 in the user interface of display.In one example, " media sharing session terminates " button may be implemented as the dedicated button on the remote controller being associated with user terminal 102, and wherein user terminal 102 can be such as TV.Similarly, user 112 can terminate media sharing session by selecting " media sharing session terminates " button.When " media sharing session terminates " button is chosen, then message will be sent to other participant of media sharing session to notify that they media sharing sessions will be moved to end, and then media sharing session terminates.User interface on each in the user terminal involved in media sharing session may return to the last user interface state of display before setting up media sharing session.Such as, if media sharing session is established during video call and private part for the user interface of video call is used for media sharing session, then at the end of media sharing session, this private part can remove from the user interface for video call, thus allows video call to reuse the part of this user interface.
In one or more embodiment described here, media data includes the photo being sent to user terminal 110 in media sharing session from user terminal 102.But, it is to be understood that, in other embodiments, media data can include other type of data, such as voice data is (such as, music data), video data or text data, and the relevant feature of the embodiment including photo with wherein media data as described herein also can wherein media data be another type of data embodiment in be carried out.In the case of media data is picture data, media sharing session here can be referred to as photo and shares (PhotoShare) session and be used to transmit the agreement of picture data in session shared by photo and can be referred to as photo and share agreement.
Photo is shared session calling (such as, video or audio call) period permission photo between the user 104 and 110 of communication system 100 and is shared.In one or more embodiments, photo is shared agreement and is designed to perspective agreement, it is allowed to additional feature is included subsequently, and does not provides additional resolver for agreement support backward.
Photo can be displayed in the specific part of the user interface on user terminal 110 at the upper photo shown of user terminal 110 (client computer shared by photo) during sharing session.When photo share session be established time, this part of user interface can be reserved for display photos and share the photo of session.When photo share session be established time, at user terminal 102 and 110 already engaged in the case of video call, this is a simple process.In this case, video call has had and has been displayed to the user interface of user 112 and it is the simple process using the part of user interface or " region " to show the photo received during session shared by photo.Such as, when photo share session be established time, user terminal 110 can initialize photo and share layout, and it is the region of display that user terminal 110 reserved by the photo received in session shared by photo.Sharing, in response to receiving photo from user terminal 110, the confirmation that session will be established, user terminal 102 (main frame shared by photo) can activate the photo of its own and share layout and share, for photo, the region that the display of user terminal 102 is reserved in session.Photo on user terminal 102 and 110 is shared layout and is exclusively used in the picture data illustrating that session shared by photo.The user 104 of user terminal 102 reserved area of display 204 from user terminal 102 can select photo (or other image) the photo of selection to be transferred to user terminal 110 during session shared by photo.Similarly, the photo (or other image) received on user terminal 110 during session shared by photo is displayed in the reserved area of the display on user terminal 110.
User terminal 110 can select to show from the EXIF data in the jpeg format relevant with picture data to user 112, and therefore user terminal 102 should maintain these data to adapt to the requirement of the user terminal 110 in Image Sharing session in the transition period of original image.
Fig. 4 shows the client computer that the example of the user terminal 102 and 110 being arranged to media sharing session, i.e. user terminal 102 are the main frames of media sharing session and user terminal 110 is media sharing session.Be connected in communication system 100 (it is, on network 108) between user terminal 102 and 110 shown in Fig. 4 is carried out.As described above, media data can be transferred to user terminal 110 for output on user terminal 110 from user terminal 102 in media sharing session.In the example that figure 4 illustrates, user terminal 102 is TV.Before media data is transferred in media sharing session user terminal 110, media data is uploaded to the memorizer 226 of TV 102 by user 104.Then, when implementing calling with user terminal 110, user 104 can set up the media sharing session with user terminal 110 and then select media data file for being transferred to user terminal 110 media sharing session from the memorizer 226 of TV 102.
Fig. 5 shows user terminal 102 and 110 example being arranged to media sharing session, and it is similar in Fig. 4, the client computer that i.e. user terminal 102 is the main frame of media sharing session and user terminal 110 is media sharing session.In example shown in Figure 5, user terminal 102 is mobile phone, and media data is stored in its memorizer 226 by it.When implementing calling with user terminal 110, user 104 can set up the media sharing session with user terminal 110 and then select media data file for being transferred to user terminal 110 media sharing session from the memorizer 226 of mobile phone 102.
In method described above, the client computer that user terminal 102 is the main frame of media sharing session and user terminal 110 is media sharing session.But, each user terminal in communication system 100 can have the ability serving as main frame or client computer in media sharing session, and similarly, in other embodiments, the client computer that user terminal 110 is the main frame of media sharing session and user terminal 102 is media sharing session.
Method described above relates to sharing between the different user in communication system 100 media data.In example described above, user 104 uses user terminal 102 to share media data with the user 112 on user terminal 110.Can be used between two user terminals of same user transmit media data for transmitting the similar principles of media data.In this case, media data is shared the most between users, but is passed between the user terminal of same user.
Such as, user 104 is associated with user terminal 102 and 106.For user 104 communication instance can user terminal 102 and 106 each on be implemented to allow user 104 use arbitrary in user terminal 102 and 106 or all sign in communication system 100.When user 104 via multiple communication instance (such as, on user terminal 102 and 106) when signing in communication system 100, then media communication session can be established and be used to media transferring data (such as, image, video, audio frequency etc.) between communication instance between communication instance.
Flow chart with reference to shown in Fig. 6, presently describes a kind of method transmitting media data between user terminal 102 and 106 in communication system 100.
In step S602, the first communication instance for user 104 is carried out on user terminal 106.As described above, user 104 signs in in communication system 100 via the first communication instance on user terminal 106.User 104 has ID in the communication system 100, and it allows user 104 to be identified in the communication system 100.Especially, the ID of user 104 can be used to carry out the certification communication to and from user 104 via the first communication instance on the user terminal 106 in communication system 100.
In step s 604, the second communication instance for user 104 is carried out on user terminal 102.User 104 also signs in communication system 100 via the second communication instance on user terminal 102.Same ID is used to identify user 104 by the first communication instance on user terminal 106 and the second communication instance on user terminal 102 in the communication system 100.The ID of user 104 can be used to carry out the certification communication to and from user 104 via the second communication instance on the user terminal 102 in communication system 100.Communication instance uses communication customer end software to be carried out, and described software is all to be provided by the client stack 216 performed on the CPU202 of user terminal 102 in this way.Similar client stack performs on the CPU of user terminal 106.
By this way, user 104 signs in communication system 100 via the first and second communication instance on corresponding user terminal 106 and 102 simultaneously.
In step S606, user 104 sets up media communication session between the communication instance on user terminal 106 and 102.Media communication session is similar to above with respect to the media sharing session described by the method for Fig. 3, except media communication session is set up between the user terminal (106 and 102) being associated with same user (user 104), and media sharing session described above is set up between the user terminal (102 and 110) being associated with different user (104 and 112).It is understood that media communication session allows the communication oneself arriving oneself in communication system 100, media data.Especially, media communication session allows using same ID to sign between the user terminal (106 and 102) of communication system 100, the communication of media data.Being similar to media sharing session described above, user terminal 106 can send a query to user terminal 102 to determine whether user terminal 102 supports media communication session before setting up media communication session.Inquiry can be sent in the random time before setting up media communication session, the such as user in response to the user 104 come on user terminal 106 inputs, or indicate him to want to set up and the media communication session of user terminal 102 in response to user 104, or on user terminal 106 or user terminal 102, sign in communication system 100 in response to user 104.
Media communication session is certified based on the same user (namely user 104) being simultaneously logged to communication system via the first and second communication instance on corresponding user terminal 106 and 102.Because same user signs in communication system 100 on user terminal 106 and 102, it can thus be assumed that user 104 trusts oneself, thus allow between user terminal 106 and 102, the communication of media data.
Once media communication session has been set up, then, in step S608, media data is passed to user terminal 102 from user terminal 106 in media communication session.Media data is passed according to the media communication agreement (can share agreement with media described above identical) of media communication session.Then the media data being passed can be exported to user 104 via the user interface of user terminal 102.Such as, under media data includes image conditions, image is displayed to user 104 on the display of user terminal 102.When the media data being passed is received from user terminal 106 in media communication session, the media data being passed can be exported on user terminal 102 automatically.
Media data is (being similar to media data transmission in media sharing session described above) of transmission in the media communication session in communication system 100.The user terminal 106 and 102 of media communication session may be located at the vicinity of user 104 so that user 104 can control user terminal 106 and 102 in media communication session.Alternatively, user terminal 106 and 102 can not be positioned at position close to each other so that user 104 can be only near in user terminal 106 and 102.
It is that user 104 provides the ability of media transferring data (such as, view data, video data, voice data, text data etc.) between the example of the user account signed in on different user terminals in communication system 100 above in regard to the method described by Fig. 6.
On when user 104 has more than one user terminal (the such as user terminal 106 and 102) that can communicate in communication system 100 and in media data is only stored in these user terminals one (such as, on user terminal 106) in the case of and different one in user 104 is desirable for his user terminal (such as, user terminal 102) output media data in the case of, this can be useful especially.User may want to different one in his user terminal (such as, user terminal 102) on export media data, because it is probably convenient or because the output device of user terminal 102 may have higher standard than the output device of user terminal 106.Such as, user terminal 106 is probably mobile phone or panel computer that media data is stored thereon and user terminal 102 is probably TV.The display of TV and speaker typically have higher standard than mobile phone or the display of panel computer and speaker.Therefore, in the case of media data includes audio frequency and/or vision data, user 104 may want to use TV rather than mobile phone or panel computer to export media data.It should also be noted that, in this example, the storage capacity of TV may be worse than the storage capacity of mobile phone or panel computer, and this may be exactly that media data is stored in the reason on mobile phone or panel computer rather than on TV by user 104.Here it is wherein with reference to the useful especially example of media communication session described by Fig. 6.
Method above with reference to described by Fig. 6 enables media data to be output from remote user terminals (it is, away from its stored place) in a controlled manner.User 104 controls the media data being output on remote user terminals.
In one or more embodiments, user terminal 106 is portable set, such as kneetop computer, phone or panel computer, and it has well for storing the storage capacity of media data.When user terminal 106 is portable, user terminal 106 can be carried to need the place of user terminal 106 by user.But, when user terminal 106 is portable, it is by typically not used for the biggest screen of output view data, it is also possible to not used for the most high-quality speaker of output voice data.In addition, in one or more embodiments, user terminal 102 is non-portable equipment, such as TV, Blu-ray player, Set Top Box or game console, it may not have the best storage capacity to store media data for user 104, but may with the most on TV for exporting the giant-screen of view data and be associated for exporting the high-quality speaker of voice data.
The character pair of the mode transmitting media data in the media sharing session between user terminal 106 and 102 described above is also applied to transmit in the media communication session between user terminal 106 and 102 mode of media data.
Such as, media data can be sent to user terminal 102 from user terminal 106 on network 108 as packets of data in media communication session.Packet is formed according to the agreement of media communication session.Each packet can include a part for media data, and wherein user terminal 102 receives multiple packet and the data from these packets combined to export media data in media communication session.Such as, each packet can include a number of data, such as 16KB or 64KB.In one example, former data are Base64 codings.The data transfer size of packet can be included as the prefix of the data in packet itself.Data transfer size should be size rather than the size of initial data itself of the data after Base64 conversion.Preferably, the media data of media communication session uses and is applied to apply (app2app) stream to be passed, and it is more more reliable than using datagram to send data.
Some of message transmission between user terminal 106 and 102 are (such as, its beginning being used to signalisation media communication session and end and be used to send inquiry and reply the ability supporting media communication session about user terminal 102, etc.) can be sent in the form of packets, described packet has the data of varying number compared with packet.These packets less than packet and such as can have 64 bytes.The agreement of media communication session is also observed in these packets.
During media communication session, user interface on user terminal 106 provides the ability browsing such as photo (it can be stored in the memorizer of user terminal 106) such media data for user 104, if and user terminal 102 supports media communication session, in media communication session, send some or all of media data when needing to user terminal 102.
In example described above, the client computer that user terminal 106 is the main frame of media communication session and user terminal 102 is media communication session.User terminal 106 is responsible for media communication session and can control which fragment of media data and be passed to user terminal 102 during media communication session.On the contrary, user terminal 102 exports media data (such as, display photos), and described media data is as and is passed when they are received from user terminal 106 in media communication session.Especially, user terminal 102 may not control which fragment of media data (such as, photo) and watched during media communication session.
For interoperability and for Information Security, some little restrictions can be placed in the embodiment of media communication session.Such as, in one or more embodiments, media communication session is transferred to the dish (that is, memorizer) that the media data of user terminal 102 may not be stored on the second user terminal 102.User terminal 106 is (i.e., the main frame of media communication session) on user terminal 102, the output of media data can be controlled, and can control it make once only have media data a fragment (such as, one file of media data) can be output on user terminal 102, wherein, user terminal 106 controls to be watched on which fragment of media data user terminal 102 in media communication session.Can be reduced by the expense in terms of the media data being not stored in being passed in media sharing session on user terminal 102, storage device in embodiment, on user terminal 110 and memorizer.Because the media data of transmission is not permanently stored at user terminal 102 (such as in media communication session, terminate do not have media data can be stored on user terminal 102 afterwards in media sharing session), then user terminal 106 is not required to that all files (such as, photo files) of media data is assigned to user terminal 102 and shows media data on user terminal 102.As described above, the media data being passed can include multiple file, and in certain embodiments, the file that is not more than in described file is stored on user terminal 102 in media communication session every time.Such as, when in file is stored on user terminal 110 in media communication session, then the reception of the next file in media communication session causes the file being currently stored on user terminal 102 will to be deleted so that newly received file can be stored on user terminal 102 from user terminal 102, and not be used in media communication session and be stored on user terminal 102 by the more than one file in file every time.Additionally, the media data being passed can be stored in the data storage on user terminal 102, it is exclusively used in the data of storage media communication session and is different from the main storage of user terminal 102.
In order to select to transfer to the media data file of user terminal 102 in media communication session, user 104 can select media data file in the film strip view from user terminal 106, as selected described by media data above in regard in media sharing session.
Being similar to as above in regard to described by media sharing session, the main frame (that is, user terminal 106) in media communication session has the form of conversion media data to adapt to the ability of media communication session, and in this meaning, it is " intelligent " main frame.Such as, the ability of the client that the form of media data can be changed to adapt to media communication session client computer (user terminal 102).The conversion of media data can include scaling and/or compression so that the size of media data (such as, the quantity of the bit of media data) it is reduced (such as, by reducing the resolution of image) to adapt to the requirement of user terminal 102, and the form of media data can be converted into the form (such as, jpeg format can be used view data) supported by user terminal 102.As above in regard to described by media sharing session, in response to about user terminal 102, whether the requirement of user terminal 102 can support that the inquiry of media communication session is indicated to user terminal 106.
Being similar to as above in regard to described by media communication session, the arbitrary participant in media communication session can terminate media communication session.
Media communication method as described herein allows user 104 that media data is transferred to user terminal 102 for output on user terminal 102 from user terminal 106.User terminal 106 and 102 may be connected to network 108 (such as, the Internet) and therefore to transmit media data in media communication session by network 108 be a simple process.This with attempt to implement for some other connection (such as, the USB between user terminal 106 and 102 connects) connects conversely, for other, user 104 will be required to set up before media transferring data connection between user terminal 106 and 102.Media communication session utilize have been coupled to the user terminal 106 and 102 of network 108 between user terminal 106 and 102 media transferring data so that user 104 was not required to before media data can be transferred set up other single connection between user terminal 106 and 102.
In one or more embodiment described here, media data includes photo, and it is sent to user terminal 102 from user terminal 106 in media sharing session.But, it is to be understood that, in other embodiments, media data can include other type of data, such as voice data is (such as, music data), video data or text data, and the relevant feature of the embodiment including photo with wherein media data as described herein also can wherein media data be another type of data embodiment in be carried out.In the case of media data is picture data, media communication session can be referred to herein as photo remotely (PhotoRemote) session and be referred to alternatively as photo remote protocol for transmitting the agreement of picture data in photo remote session.
Photo remote session allows photo in the transfer signed between multiple examples of user of communication system 100.
