Description
Technical field
The present invention relates to Video Transcoding Technology field, more particularly to a kind of video transcoding method and system.
Background technology
Video coding is widely used in the occasions such as Internet transmission of video, DTV, video conference.Different applications pair
Video Codec, video data Store form, web-transporting device etc. have different requirements.It is worked out for specific area
Coding standard is also not quite similar, such as：MPEG22 standard digital TV orienteds；H.263 for formulations such as videoconferences；MPEG24's
Super Low Bit-rate Coding is more suitable for mobile multimedia application etc..In order to enable between access device between heterogeneous network, different
And can be seamlessly connected between different multimedia data format, Video Transcoding Technology is just particularly important, for example in video
In VOD system, after video server adds transcoder, people can pass through wireless request video-on-demand service；In monitoring system
In, In2ternet remote monitorings can be passed through after contextual data transcoding；In digital television broadcasting field, if it is desired to any one
Kind of multimedia terminal can receive digital broadcasting, then all must be by similar set-top box or video gateway from code check to resolution ratio
Equipment works to complete transcoding.
Video Transcoding Technology is exactly that compression video is handled end to end, i.e. input, the output of transcoder are all pressures
Contracting data, the compression bit rate after transcoding are suitable for the requirement of transmission bandwidth and receiving terminal.That is, video code conversion refers to
The video code rate of compressed encoding is converted into another video code rate, to adapt to different network bandwidths, different terminals
Processing capacity and different user demands.Transcoding is substantially one and first decodes, the process of re-encoding, therefore converts front and rear code
Rate may follow identical video encoding standard, it is also possible to not follow identical video encoding standard.
Traditional video code conversion mode carries out being then forwarded to terminal after transcoding generally according to different types of terminal manually
Player plays out.For example, the broadcasting of competitive sports, needs personnel transcoding device to be called to record scene according to the demand of terminal
The video of system carries out transcoding.When needing to be transferred on computer web player, personnel need invoking web page video transcoding device；
And it is again different for the video that mobile phone plays, broadcast format etc. and the video played on computer, at this point, personnel need to call hand again
Machine video transcoding device.Therefore, traditional this video code conversion mode can not carry out automatic transcoding.

Specific embodiment
Fig. 1 is the flow chart of video transcoding method according to an embodiment of the invention.An embodiment of the present invention provides one
Kind video transcoding method, including：
Task generation step 100：Generate video code conversion task.Video code conversion task includes the source format and purpose of source video
The object format of video.Since the transcoding units that different source formats is converted into different object format needs are different, depending on
Frequency transcoding task must clear and definite source format and object format.For example, source format can be learnt according to the form of source video, object format
It can be learnt according to the user demand of terminal.
Start transcoding step 200：Corresponding transcoding units are started according to source format and object format.
Transcoding step 300：Transcoding units carry out transcoding to source video, export purpose video.
Transfer step 400：Transmission purpose video to terminal plays out, to realize that terminal can be played in source video
Hold, that is, play purpose video.
The video transcoding method of the present embodiment can automatically generate video code conversion task, the automatic transcoding units and automatic of calling
It carries out transcoding and automatically delivers purpose video, fully achieve automating, being rapid for transcoding, it is convenient, efficient.It for example, can
The purpose of for source video file to be converted into mp4, flv video file, according to demand the difference of form be automatically converted into difference
Purpose video file to meet the broadcasting of user in website or TV programme etc., realizes the automatic of video easily and fast
Change transcoding.
In another embodiment of the presently claimed invention, as shown in Fig. 2, in video transcoding method, in task generation step 100
Before, it further includes：Multiple transcoding units are configured, each transcoding units correspond to a source format and an object format.

Business, video code conversion task include the source format of source video and the object format of purpose video.Transcoding units 30 are used for source video
Transcoding is carried out, exports purpose video.Video code conversion module 20 is used to start corresponding transcoding list according to source format and object format
Member 30.Sending module 40, for transmitting purpose video to terminal.
In another embodiment of the presently claimed invention, as shown in figure 4, video code conversion system further includes receiving module 11 with after
Continuous processing module 35.Receiving module 11 needs for obtaining the network bandwidth of terminal of access, the processing capacity of terminal and/or user
It asks and sends task generation module 10 to.Specifically, task generation module 10 is used to be given birth to according to the user demand of the terminal of access
The code check of purpose video is generated into video code conversion task and according to the network bandwidth of terminal and the processing capacity of terminal of access；Turn
Code unit 30 is used to carry out transcoding to source video according to object format and code check and exports purpose video.Subsequent processing module 35 is used
In purpose video being proofreaded or is carried out other processing, such as available for encryption.
Transcoding units 30 are configured as multiple.Each transcoding units 30 include data interface module, hardware interface module, deposit
Store up management module, transcoding algorithm module, data processing module, control management module and interactive module.Data interface module is responsible for
Processing data are output and input, and hardware interface module is responsible for communicating with computer hardware driver, and memory management module is born
Blame the distribution of the memory spaces such as memory, transcoding algorithm module provides the algorithm means of transcoding processing work, data processing module into
The specific data processing of row transcoding, control management module carry out the control and information processing of entire transcoding work, and interactive module carries
For the interaction of task generation module 10 and transcoding units 30, the parameter informations such as object format, the code check of purpose video are obtained.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
