Abstract

Providing access to additional content, comprising dynamic image content, during playback of video sequences. The sequences comprise a keyed video sequence including an embedded sub-image itself comprising display keys of different formats. The different format of keys consist of a sequence of characters belonging to different character sets, each corresponding to different key entry mechanisms respectively. The sequence is played back at a user terminal (118) and a user selected key entry comprising one of the display keys is collected from an input device (130, 132). Data representing the selected key is communicated to a remote system (124), to enable the remote system to resolve the key to identify an associated link to additional content (122). Data is received from the remote system comprising data representing the link. The additional content associated with the selected key is accessed in response to the entry of the selected key and the receipt of the data representing the link.

Description

Method and apparatus for providing access to additional content during playback of video sequences
Field of the invention
The present invention relates to a method and apparatus for providing access to additional content during playback of video sequences which, when received, comprise dynamic image content.
Background of the Invention
Methods for providing access to additional content during playback of video sequences are known where an indication is displayed by the video playback device in order to present a link to the additional content. The indication may be in the form of, for example, a prompt presented to the viewer during a video sequence indicating that additional content can be accessed by pressing a particular button on an input device, or the indication may be a viewer selectable link that forms part of the video sequence such as a hyperlink that overlays a portion of the video sequence. Such methods allow the viewer to conveniently access additional content related to the video sequence that is being presented.
However the methods for accessing additional content during playback of video sequences outlined above require complex techniques for presenting a suitable indication to a viewer at an appropriate time during playback. These methods require means for transmitting a trigger to a playback device that are specific to the capabilities of the video distribution technique and video receiver used. For example, a video sequence distributed via a terrestrial digital television broadcast may have trigger data embedded in the broadcast indicating that an indication may be presented to the user, and may indicate the location of the additional content to which the video receiver may be directed if the user wishes to access this additional content. The video receiver must be able to interpret the trigger data transmitted as part of the video distribution that indicates that an indication should be presented to the user and as a result present a prompt to the user on a video display. Finally where the video sequence is recorded, a video recorder may not be able to record the trigger data transmitted as part of the broadcast to allow access to the additional content on subsequent playback after recording.
Accommodating new trigger transmission techniques for every combination of existing video distribution technique and video receiver requires significant complexity on the video receiver. Additionally, accounting for the variety of triggering mechanisms places a heavy burden on those who wish to insert triggers for additional content into a video sequence before distribution via a variety of distribution techniques.
US patent publication number 2005/0015817 Al is an example of a technique for providing access to additional content during playback of a video sequence where the video sequence is distributed via a specific distribution method, in this case via terrestrial analogue television broadcast. Additionally there is described a receiver that is able to record in a storage medium broadcast data relating to the appearance of a trigger for additional content during the video sequence, as well as the video sequence itself This technique falls into the category of a specialised method for a particular video distribution technique and video receiver however, and hence it suffers from the same problems as other techniques in this category as highlighted above.
PCT publication number 2002/056590 Al describes a video receiver comprising means for receiving television signals containing additional information data to allow the representation of an interactive image for display.
The interactive image comprises a number of viewer-selectable items each associated with additional content, the receiver being responsive to viewer manipulation of an input device for selection of one of the items to cause the additional content associated with the selected item to be provided. Additionally each of the items is associated with a key uniquely identifying the service associated therewith, wherein user selection of an item is effected by entry into the input device of the key associated with the service to be selected. Resolution of a key to a link to content is achieved by the video receiver receiving information data broadcast as part of the received television signal, said information data containing a plurality of keys and a plurality of corresponding links to content. Once again however this is a specialised triggering method that requires a particular video distribution technique and video receiver capable of receiving information data relating to links to additional content related to a video sequence via the distribution.
US patent publication number 2003/0142237 Al describes the inclusion of a logo or brand image as a sub-image in a video sequence, the inclusion in a broadcast of the video sequence of information data referencing a teletext page or an internet address related to the video sequence, and an appropriate receiver required to access the referenced additional data, As a result this is once again a specialised triggering method that requires a particular video distribution technique and video receiver capable of receiving information data relating to links to additional content related to a video sequence via the distribution. As an alternative it is indicated that an Internet address could be included in a sub-image of a broadcast video sequence, but this requires the viewer to remember and then enter this internet address to access additional content, hence ease of access to additional content is not provided due to the complex nature of many internet addresses.
Hence prior art fails to overcome the difficulty of providing a method for presenting a trigger or prompt to the user indicating the presence of additional content that the user is able to access easily and that is independent of the video distribution technique and video receiver used. It is an object of the present invention to provide such a method.

Detailed Description of the Invention
A detailed description of exemplary embodiments of the invention follows with reference to the figures provided.
Figure 1 schematically illustrates the principle components and communication links of a system for providing access to additional content during playback of video sequences according to different embodiments of the present invention. A key embedding device 110 creates a keyed video sequence by embedding a key image 102 as a sub-image within the dynamic image content of a video sequence 100 at the points in the sequence specified by the key display schedule 108. The sub-image comprises of a first display key of a first format and a corresponding second display key of a second format, the first format of key consisting of a sequence of characters belonging to a first character set and the second format of key consisting of a sequence of characters belonging to a second character set which is different to the first character set.
For example, the first display key consists of a sequence of numeric characters and the second display key consists of a sequence of alphanumeric characters.
More particularly, in preferred embodiments, the first display key consists of a sequence of solely numeric characters, and the second display key consists of a sequence of solely alphanumeric characters, including both alphabetical and numeric characters and/or only alphabetical, non-numeric characters.
Additionally in preferred embodiments the second character set corresponds to the first character set by way of a mapping of individual characters, for example the alphanumeric characters a', b', c' and 2' from the second character set map to the numeric character 2' in the first character set and the alphanumeric characters d', e', f' and 3' from the second character set map to the numeric character 3' in the first character set, etc. A key monitor device 104 may be used in one embodiment of the invention to monitor the presence of a sub-image containing a key in the keyed video sequence.
The keyed video sequence is then distributed using a video distribution technique 106 for example terrestrial digital television broadcast, and the distribution is received by a video receiver 118 such as a set-top box for receiving a terrestrial digital television broadcast. The video receiver 118 decodes the received video distribution 106 using a video decoder 116 and reproduces the keyed video sequence using a video display 112 such as a television.
The video receiver 118 is also provided with a key entry application 120 that receives from a user a user selected key entered using either a first input device 130 comprising a first key entry mechanism, for example a numeric keypad, that is able to enter characters from the first character set, or using a second, different, input device 132 comprising second key entry mechanism, for example an alphanumeric keypad, that is able to enter characters from the second character set. For example the first input device is a television remote control device having a numeric keypad and no alphabetical keypad and the second device is a keyboard device having an alphanumeric keypad.
The user selected key entered by the user is communicated to a remote system 124, which in this embodiment is a key resolution server, via a communications network 126 such as the Internet. The remote system 124 uses a key database 128 to resolve the received key to a link to content, such as a Universal Resource Locator (URL), that is associated with the user selected key.
Both the first display key and the second display key, if selected by the user for entry, are resolved to the same link to content. Thus, the system provides flexibility with respect to the key input mechanism available to the user. If the user has a solely numeric keypad, or other numeric character entry mechanism, the user may select to enter the numeric format of display key. If the user has an alphanumeric keyboard, or other alphanumeric character entry mechanism, the user may select to enter either the numeric format of display key or the alphanumeric format of display key. Some users may select to enter the alphanumeric format of display key, since if this is a memorable word or alphanumeric character sequence, including both alphabetical and numeric characters and/or only alphabetical, non-numeric characters, it may be easier to remember. Note that the user may enter a user selected key which does not correspond to the currently displayed set of display keys, in which case the user may select a key from memory, having noted the key from a previously displayed set of keys in a previously played back video sequence.
The link to content resolved from the received key is communicated back to the key entry application 120 via the communications network 124. The key entry application 120 receives the link to content from the remote system 124 and passes this to a browser application 114 which uses it to make a request for content via the communications network 126. A content source 122 such as a web page on the World Wide Web (WWW), directed to by the link to content returns the requested content to the browser application via the communications network 126. The browser application 114 then renders the content retrieved from the content source and displays it to the user on the video display 112.
Figure 2 shows schematically the video receiver 118 and the components of which it is comprised according to different embodiments of the present invention. Within the video receiver 118 a distribution receiver 200, such as a tuner for receiving a terrestrial digital television broadcast, receives the video distribution 106 which is decoded by a video decoder 116 such as a Motion Picture Experts Group (MPEG) decoder. The decoded video is then prepared for output on a video display 112 by the video output component 202, for example by converting the decoded video to a composite video signal.
The receiver also consists of a microprocessor 206 that processes instructions stored in a random access memory (RAM) 208 that implement a browser application 114 and a key entry application 120. The video output component 202 is able to render graphics produced by programs running on the microprocessor 206 and multiplex these with the video sequence produced by the video decoder 116. The microprocessor 206 can process user input received from means 204 for accepting user input from either a first input device 130 or a second input device 132. A network interface 210 such as a network card or a broadband modem is provided that allows the receiver to connect to a communications network 126 such as the ntemet.
Figure 3 shows an exemplary screenshot 300 of dynamic video content 302 into which a sub-image 304 has been embedded. The sub-image comprises of a first display key 308 of a first format and a corresponding second display key 306 of a second display format.
Figure 4 shows an exemplary screenshot 400 of the screen displayed by the key entry application when it is invoked by the user. The screen contains a key entry field 402 into which the user may enter a key using an available input device.
Figure 5 illustrates the steps carried out in order to provide access to additional content during playback of video sequences according to a particular embodiment of this invention. Initially a keyed video sequence containing a sub-image comprising a first display key and a second display key is received from a video distribution and displayed on a video display by the video receiver (step 500). If the user wishes to access additional content related to the video sequence, the user may start the key entry application on the video receiver (step 502), for example by pressing a button on an input device. When the video receiver accepts input from the user that indicates the key entry application should be started, the video receiver displays the key entry application (step 504), for example by overlaying the graphics of the key entry application over the dynamic video content output from the video decoder.
Once displayed the key entry application receives characters entered by the user using an available input device, the received characters forming a user selected key (step 506). The user selected key entered by the user is then communicated to a remote system using the network interface to a communications network (step 508). The remote system identifies the format of key of the user selected key as either a first key format consisting of characters belonging to a first character set or a second key format consisting of characters belonging to a second character set, and the remote system then looks up the user selected key in a database (step 510) and by using the user selected key as an index into the identified format of key entries in the database retrieves a link to content associated with the key that may be for example a URL. In other embodiments of the invention the key entry application communicates the type of character set used when entering the user selected key as being either the first character set or the second character set according to the capabilities of the input device used to enter the user selected key and communicates this type of character set used to the remote system along with the user selected key.
The key entry application running on the video receiver then receives a link to content associated with the user selected key from the remote server via the communications network (step 512). The key entry application then extracts the link to content, for example a URL, from the information received from the remote system (step 514). The link is then passed to the browser application which then uses it to make a request for content from a content source via the communications network (step 516), where for example the content source is a web page on the World Wide Web. The browser application then receives the content transmitted by the content source via the communications network (step 518) and renders it for display on the video display (step 520).
Figure 6A shows an exemplary screenshot 600 of the screen displayed by the key entry application after the user has entered a key 602. Figure 6B shows an exemplary screenshot 604 of additional content that is displayed by the browser application after retrieving a link to content associated to the user selected key.
Figure 6C illustrates an example of the contents of a database used by a remote system to resolve either a first format of key or a second format of key to a particular link to content.
Figure 7 illustrates the steps carried out in order to provide access to additional content during playback of video sequences according to a particular embodiment of this invention. Initially a keyed video sequence containing a sub-image comprising a first display key and a second display key is received from a video distribution and displayed on a video display by the video receiver (step 700). Tf the user wishes to access additional content related to the video sequence, the user may start the key entry application on the video receiver (step 702), for example by pressing a button on an input device. When the video receiver accepts input from the user that indicates the key entry application should be started, the video receiver displays the key entry application (step 704), for example by overlaying the graphics of the key entry application over the dynamic video content output from the video decoder.
Once displayed the key entry application collects from an input device one or more characters of a first input character selection (step 706). The first character selection entered by the user is then used to query a database (step 708) and to acquire a response from the query comprising data identifying a first set of user selectable keys which include characters corresponding to the first input selection (step 710). In one embodiment of the invention the first character selection is communicated to a remote system via a communications network, the remote system then performs the database query and the key entry application then receives data from the remote system via the communications network, the data comprising the first set of user selectable keys. The first set of user selectable keys are preferably keys of the alphanumeric format, even if the user is entering only characters in the form of numeric digits. In such case, the remote system performs mapping between the different key formats in order to identify the first set of user selectable keys.
Tn other embodiments of the invention the step of communicating the first character selection is triggered in response to the collection of a predetermined number of characters from the input device.
The key entry application renders the first set of user selectable keys for display on the video display (step 712). If the key entry application receives another character entered by the user (step 716) the first set of user selectable keys is either filtered to show only those keys that begin with the same characters entered by the user if the first character selection comprised of characters from the second character set, or filtered to show only those keys that begin with those characters in the second character set that correspond to those in the first character set entered by the user if the first character selection comprised of characters from the first character set (step 714). This process continues until either the key entry application receives input from the user indicating that the entered key has been selected, for example by receiving an enter' key input from an input device, or until the key entry application receives input from the user indicating that a key displayed in the first set of user selectable keys has been selected, for example by receiving up' and down' key inputs from an input device to highlight a chosen key in the displayed set followed by an enter' key input from an input device to select the highlighted key in the displayed set (step 718). The key thus selected by the user is the first user selectable key (step 720).
The first user selectable key is then communicated to a remote system using the network interface to a communications network (step 722). The remote system looks up the first user selectable key in a database (step 724) and retrieves a link to content associated with the key that may be for example a URL. The remote system then transmits the link to content associated to the first user selectable key to the key entry application running on the video receiver via the communications network (step 726). The key entry application then extracts the link to content, for example a URL, from the information received from the remote system (step 728). The link to content is then passed to the browser application which then uses it to make a request for content from a content source via the communications network (step 730), where for example the content source is a web page on the World Wide Web. The browser application then receives the content transmitted by the content source via the communications network (step 732) and renders it for display on the video display (step 734).
Figure 8 shows an exemplary screenshot 800 of the screen displayed by the key entry application after the user has entered a first input character selection 802. Also shown is the first set of user selectable keys 804 that have been received from a remote system in response to a communication from the key entry application containing the first input character selection.
Figure 9 illustrates the steps carried out in order to provide access to additional content during playback of video sequences according to a particular embodiment of this invention. Initially a keyed video sequence containing a sub-image comprising a first display key and a second display key is received from a video distribution and displayed on a video display by the video receiver (step 900). If the user wishes to access additional content related to the video sequence, the user may start the key entry application on the video receiver (step 902), for example by pressing a button on an input device. When the video receiver accepts input from the user that indicates the key entry application should be started, the video receiver displays the key entry application (step 904), for example by overlaying the graphics of the key entry application over the dynamic video content output from the video decoder.
Once displayed the key entry application collects from an input device one or more characters of a first input character selection (step 906). The first input character selection entered by the user is then used to query a database (step 908) and to acquire a response from the query comprising data identifying a first set of user selectable keys which include characters corresponding to the first input selection (step 910). In one embodiment of the invention the first character selection is communicated to a remote system via a communications network, the remote system then performs the database query and the key entry application then receives data from the remote system via the communications network, the data comprising the first set of user selectable keys. In other embodiments of the invention the step of communicating the first character selection is triggered in response to the collection of a predetermined number of characters from the input device.
The key application renders the first set of user selectable keys for display on the video display (step 912). If the key entry application receives another character entered by the user (step 916) the first set of user selectable keys is either filtered to show only those keys that begin with the same characters entered by the user if the first character selection comprised of characters from the second character set, or filtered to show only those keys that begin with those characters in the second character set that correspond to those in the first character set entered by the user if the first character selection comprised of characters from the first character set (step 914). This process continues until either the key entry application receives input from the user indicating that the entered key has been selected, for example by receiving an enter' key input from an input device, or until the key entry application receives input from the user indicating that a key displayed in the first set of user selectable keys has been selected, for example by receiving up' and down' key inputs from an input device to highlight a chosen key in the displayed set followed by an enter' key input from an input device to select the highlighted key in the displayed set (step 918). The key thus selected by the user is the input user selectable key (step 920).
The input user selectable key entered by the user is then communicated to a remote system using the network interface to a communications network (step 922). The remote system then looks up the input user selectable key in a database (step 924) and retrieves one or more links to content associated with the input user selectable key (step 926). The one or more links to content is then received by the key entry application from the remote system via the communications network (step 928).
If the one or more links to content received by the key entry application consists of more than one link to content the key entry application renders a plurality of user selectable links from the more than one link to content, and displays this plurality of user selectable links (step 932). The key entry application then waits until input is received from the user indicating that one of the plurality of user selectable links to content has been selected, for example by receiving up' and down' key inputs from an input device to highlight a chosen selectable link in the displayed plurality of user selectable links followed by an enter' key input from an input device to select the highlighted selectable link (step 934). The link thus selected by the user is the first user selectable link.
In step 936 the key entry application has either received one link to content from the remote system, or has acquired a first user selectable link from the user. The key entry application extracts a link to content, for example a URL, either from the one link to content or from the first user selectable link.
The link to content is then passed to the browser application which then uses it to make a request for content from a content source via the communications network (step 938), where for example the content source is a web page on the World Wide Web. The browser application then receives the content transmitted by the content source via the communications network (step 940) and renders it for display on the video display (step 942).
In one embodiment of the invention the remote system also transmits to the key entry application text and images that summarise the content provided by each link to content that forms the plurality of user selectable links. In the same embodiment of the invention the summary of the content provided by each link to content is displayed in conjunction with the plurality of user selectable links.
In other embodiments of the invention the remote system filters the one or more links to content according to the geographical location of the video receiver that is running the key entry application before communicating a filtered one or more links to content to the key entry application. For example, some links to content may be associated with particular geographical areas, as specified in the key database. In one embodiment of the invention the video receiver may have a unique identifier that is transmitted to the remote system when key resolution requests are made via the communications network. In this embodiment of the invention the unique identifier may be used by the server to identify the location of the video receiver, or in other embodiments the remote system may look-up the unique identifier in a database of video receivers and extract the video receiver's geographical location from the database. In other embodiments the video receiver may be a mobile device and its geographical location may be determined by a positioning system running on the device that communicates the geographical position of the device to the remote system when a key resolution request is made. For example the positioning system might be a receiver for a Global Positioning System (GPS), or may utilise position information from a mobile communication method such as the Global System for Mobile Communications (GSM).
Figure 10 shows an exemplary screenshot 1000 of the screen displayed by the key entry application in step 932 after a list of links to content has been received from the remote system in step 928. The user has entered an input user selectable key 1002 that corresponds to several links to content that are displayed as a plurality of user selectable links 1004. Optional images 1006 and text 1008 that summarise the content provided by each link to content are shown, according to one embodiment of the invention.
