Abstract
The invention discloses a digital television navigation method, a system and a corresponding device. The method comprises the following steps: receiving a program transmission TS stream, and analyzing the received TS stream to obtain video basic code ES streams and audio ES streams; placing the audio ES streams into a cache, and splicing the video ES streams into a video ES stream; taking out an audio ES stream corresponding to a focus mosaic cell, packaging the audio ES stream and the spliced video ES stream into a TS stream, and sending the TS stream to a moving picture expert group MPEG hardware decoder. In the embodiment provided by the invention, the splicing of the video ES streams is not performed at the server side, and instead, the digital television terminal analyzes the received program TS stream into video ES streams, the video ES streams are then spliced into a video ES stream, and the splicing of mosaic television program ES streams are completed at the digital television terminal, thereby providing an interface for the user to set an individualized mosaic page and realizing the individualized mosaic television navigation.
Description
Technical field
The present invention relates to the digital television techniques field, relate in particular to a kind of digital television navigation method, system and corresponding device thereof.
Background technology
Digital Television has been enriched the program of simulated television to a great extent, still along with the increase of amount of information, has also increased the difficulty that the user searches program, and particularly digital TV channel becomes increasingly abundant, and browses TV programme and has become a hard job.Mosaic service provides the scheme of conveniently browsing TV programme, and it can the more direct content that represents broadcast items to the user.
Mosaic service is that screen is divided into several zonules, each zonule shows the full dynamic video mosaic of each channel digital television program, the user only needs to move arrow by remote controller, selection by little picture just switches to wants the program channel watched, the interactivity and the friendly of mosaic navigation channel have been demonstrated fully, user's demand has also obtained farthest satisfying, and 100 channels turn over also just can all browse about 5 times and finish.Operator can also sort out program in advance, such as all programs of CCTV are placed on same picture, all entertainment channels is placed on same picture ... be more conducive to the televiewer and easily pick out own favorite program from programs up to a hundred.
The major function of traditional mosaic server is to parse video transmission TS stream and audio TS stream from a plurality of program streams that are input to server, video TS stream is decoded into meets (the MPEG of live image panel of expert, Motion Picture Expert Group) standard storage form YC color coding (YUV) data, then with the yuv data down-sampling, again the yuv data behind a plurality of down-samplings is spliced into a yuv data, again spliced yuv data is encoded into video TS stream, then audio TS stream and the video TS stream that is encoded into is sent to digital TV terminal through multiplexing synthetic mosaic TV programme TS stream and by network; Digital TV terminal receives this mosaic TV programme TS stream, delivers to the decoding of the MPEG of dynamic moving expert group hardware decoder.
The present inventor finds in to the research of above-mentioned prior art and practice process, traditional mosaic service is really convenient, and the user browses TV programme, but professional traditional mosaic TV programme TS stream flows prior splicing at server end with each TV programme TS and re-sends to digital TV terminal well, the picture that all digital TV terminals are seen all is the same, and this has just limited the demand of user to personalization.
