Above-mentioned mobile phone carries out net cast towards set-top box and PC the method for work of system is as follows:
At first, handset audio collecting unit and mobile video collecting unit are gathered voice data and video data respectively, and the data of being gathered are separately carried out time mark with current acquisition time;
Then, mobile video coding unit and handset audio coding unit are separately encoded video data and voice data separately;
Then, the data of the writing unit of mobile phone after with described mobile video coding unit and each own coding of the handset audio coding unit buffer area that writes described mobile phone memory cell respectively sends respectively treating;
Then, the data wireless in the described buffer area of the wireless transmit/receive units of mobile phone is sent on the video server, the data deletion that the delete cells of mobile phone has sent the described wireless transmit/receive units in the described buffer area;
Then, the network communication unit of video server receives from the voice data of the wireless transmit/receive units of described mobile phone and video data and live client and sends live request;
Then, the video decoding unit of video server and audio decoding unit separately described network communication unit is received video data decoding be that YUV video data, voice data are decoded as audio frequency PCM formatted data;
Then, the data buffer unit of video server gives buffer memory respectively in order to stand-by with the audio frequency PCM of video decoding unit and the back gained of audio decoding unit decoding and the buffer area that YUV video data is put into described server storage unit;
Then, the audio-visual synchronization unit of video server carries out the audio, video data in the buffer area synchronously according to its timestamp;
Then, the live Signaling Processing Unit of video server is handled the live request of the live client of described network communication unit reception, to determine the needed audio/video information of live client and its audio/video coding form that is adopted;
Then, the server video encoding unit of video server and server audio coding unit are separately according to described live Signaling Processing Unit needed audio/video information of determined live client and audio/video coding form, the corresponding YUV video data of buffer memory is carried out corresponding encoded and corresponding audio frequency PCM data are carried out corresponding encoded, both each self energys are carried out multiplex coding simultaneously;
Then, the audio, video data of the live data transmitting element of video server after with server video encoding unit and server audio coding unit coding transferred to the network communication unit and sent to live client;
At last, the audio, video data of the merging of server stream unit after with video encoding unit and audio coding unit coding according to industrial standard generates the video file of standard, and deposits the step that described memory cell is used for the non-live program request of client in.
Therefore, 1, mobile phone is voice data and video requency frame data separately to be sent rather than transmit merge good video flowing; 2, there is a data buffering area in the mobile phone memory cell, promptly voice data behind the coding and video data directly do not send, but put into buffering area earlier, and then by the transmission of from buffering area, fetching data of the wireless transmit/receive units of mobile phone, the purpose of doing like this is because the communication network that mobile phone wireless adopted is also unreliable and bandwidth is lower, can be earlier when network condition is bad data buffering rather than abandon, it is complete can making the video file data of preserving on the video server like this; 3, have independent voice data buffer memory subarea and video data buffer memory subarea in video server, existing for what video server was finished audio frequency and video of these two buffer memory subareas provides condition synchronously; 4, server audio frequency buffer memory subarea and server video cache subarea are in audio decoder module and video decode module rear, what wherein deposit is decoded Voice ﹠ Video data, and this live TV stream of exporting multichannel different coding form simultaneously for video server provides condition; 5, in video server, immediate data transmitting element and stream merge cells are separated, when video server provides direct broadcast service, also preserved a video file like this for the usefulness of carrying out program request in the future; 6, finish in the audio-visual synchronization processing unit of the Synchronous Processing of audio frequency and video in video server, rather than finish in live client.
In sum, mobile phone of the present invention is by the video source of mobile phone as video living transmission system towards system and the method for work thereof that set-top box and PC carry out net cast, and after the data in video server receiver, video source, request that should each live client, video data and voice data are met the coding that each client requires separately, thus, can realize uploading one road real-time audio frequency and video input and the audio/video flow of output multichannel different-format by mobile phone.To satisfy the demand of different clients, can promote the attraction of mobile phone and video server greatly.
The foregoing description just lists expressivity principle of the present invention and effect is described, but not is used to limit the present invention.Any personnel that are familiar with this technology all can make amendment to the foregoing description under spirit of the present invention and scope.Therefore, the scope of the present invention should be listed as claims.
