Embodiment
Mobile phone 3D television video player method of the present invention, comprises the following steps: use image pick-up card to gather 3D TV signal, obtain the 3D video data meeting the requirement of 3D video image clarity; Adopt compressed format H.264+mp3, under the prerequisite ensureing compressed video quality, select the resolution, code check and the frame per second parameter that meet 3D television video and require; Adopt privately owned packing form, the audio frequency and video after compression are packed, generate packaging file; After packaging file uploads onto the server, cell-phone customer terminal is by after request, download and decoding, and on mobile phone, 3D television video is reproduced in reduction.
As shown in Figure 1, cell-phone customer terminal for the broadcasting step of 3D video channel is:
Enter specified channel, request video, server sends designated;
Receive data, audio/video frames is separated, recombinate;
After receiving full predetermined quantity frame, start to play.

Import one-frame video data into, adopt H.264 algorithm decoding designated frame;
Described frame data are zoomed to given resolution;
Do image according to panel type to interweave;
Image after display interweaves.
There is larger difference file packing aspect with package form in the past, tradition package form is synchronous in order to ensure enough School Affairs in transmitting procedure, encapsulation format occupies larger bit stream, consider that this programme is under Transmission Control Protocol, the steps such as fault-tolerant verification can accomplish that very well, we have employed the bit stream that privately owned form occupies to reduce encapsulation.In privately owned form customization procedure, what time following main realization is:
1) preliminary check and fault-tolerant is met; 2) audio-visual synchronization is met; 3) audio frequency and video fast forwarding and fast rewinding demand is met; 4) bit stream that takies of privately owned form is enough low.
Internal memory use, in order to ensure to apply enough speeds of service, promotes Consumer's Experience, internal memory process have also been made relevant treatment, and first, analytical applications is to the frequency of utilization of internal memory, the internal memory frequently used is united, extracts from general memory and be divided into memory block.Under GSM mobile handset, utilize system interface, change Overlay region, by what repeat, the code of non conflicting removes when application enters and is saved on SD card, then carries out, from new division, simulating region of memory, and externally providing read-write interface to this region.When applying and exiting, the Code on SD card is reverted to this region.The method mainly promotes read-write efficiency, thus promotes application speed.
Video is placed in independently buffering area.Buffering area is that a bulk of independently Buffer, this Buffer are divided into equal-sized multiple memory cell block, and each block all can independently decoding compressed unit.Data Structure Design is carried out to buffering area, multiple memory cell block is carried out ending and be connected, make the cache blocks recycled.For each little module unit, increase corresponding information, as the time, frame per second, resolution etc., these are all written in the data structure of buffering area, facilitate follow-up carry out compression process (any autonomous block independently can be revised and is edited), raising controllability.
