Abstract
The invention relates to a method for processing intelligent personal television (IPTV) network television data of a global system for mobile communication (GSM) mobile phone. The method comprises the following steps of: eliminating audio-video data which does not accord with a standard format from a service end; detecting and discarding data packs with errors in transmission; separating audio data and video data of the audio-video data according to a protocol of a data transmission layer; decoding obtained data, storing the obtained data in a buffer area respectively, then processing the obtained data respectively, and finally reading the video data and the audio data respectively; performing integration and packaging according to process tracking and supervising (PTS) information; storing the packaged audio data and video data to the buffer area and connecting the packaged audio data and video data with each client; and reading corresponding audio and video data from the buffer area according to requests of the clients, and transmitting the audio and video data to corresponding clients through a network. The method reduces the cost of a mobile phone end, can automatically expand a program source, upgrades the experience effect of the mobile phone television to the maximum extent, ensures the continuity and the consistency in the data transmission, and simultaneously, effectively reduces non-essential bytes in the data transmission.
Description
Technical field
The present invention relates to mobile phone IPTV Web TV technology, particularly relate to GSM mobile handset IPTV Web TV processing method of data.
Background technology
Be accompanied by the development of society, mobile phone institute's role in people's life is increasingly important.People more and more pay close attention to the amusement function on the mobile phone, and aspect amusement, see that by mobile phone TV becomes the important bright spot of cellphone multimedia amusement again.
See that by mobile phone the realization of TV mainly is by increasing TV chip on mobile phone, playing TV by receiving wireless television signal in the market.Difference according to TV chip mainly is divided into following three schemes:
1, analog signal chip (Analog signal chip).Mainly be to receive analog signal, and carry out processes and displays.Shortcoming: program channel is single, and image quality is relatively poor, and jitter contains much information, and mobile phone end power consumption height is handled complexity, defectives such as cost height.
2, digital signal chip (DTV signal chip).Receiving digital signals, and carry out processes and displays.Shortcoming: program channel is single, contains much information, and the mobile phone end is handled complicated, and power consumption is very big, defectives such as cost height.
3, mobile television signal chip (CMMB signal chip).Receive the handheld device TV signal, and carry out processes and displays.Shortcoming: joint channel order is single, chip expense height, and mobile phone end power consumption is bigger, and region limits is arranged, and is also at the experimental stage at present, and video flowing needs charge, and process chip needs copyright fee, defectives such as cost height.
Comprehensive above the analysis as can be seen, scheme existed program single in the past, and image quality is undesirable, the overall expenses height, the compartmentalization restriction consumes more high shortcoming when chip uses.
Summary of the invention
Technical problem to be solved by this invention is exactly to provide GSM mobile handset IPTV Web TV processing method of data for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: GSM mobile handset IPTV Web TV processing method of data, it is characterized in that, and may further comprise the steps:
A. service end is rejected the audio, video data that does not meet reference format;
B. detect and abandon the misdata bag that produces in the transmission, according to the agreement of data transfer layer separately, preserve the corresponding timestamp PTS information that shows simultaneously the voice data of audio, video data and video data;
C. the voice data that obtains is decoded, export the PCM formatted data of original band time slot Ts, and be saved to first buffering area;
D. the video data that obtains is decoded, export original video data, and be saved to second buffering area;
E. from the second buffering area reading video data, dwindle downscale, the image after dwindling is carried out precommpression, and the video data after will compressing is saved to the 3rd buffering area by the secondary differential technique;
F. read voice data in order from first buffering area, carry out the high compression ratio compression, be saved to the 4th buffering area after the encapsulation;
G. from the 3rd buffering area and the 4th buffering area reading video data and voice data respectively, merge and encapsulate according to PTS information, and the audio, video data after will encapsulating is saved to the 5th buffering area;
H. connect with each client, read corresponding audio, video data according to the request of client from the 5th buffering area, and send to corresponding client by network.
Described reference format comprises mpeg format video+AAC format audio, Analog format video+PCM format audio, mpeg format video+AC3 format audio and H264 format video+amr format audio.
Described service end and client are advanced alternately by the ETV flow host-host protocol, and this ETV flow host-host protocol comprises:
At first set up a connecting path before client is connected with service end, service end and client are all opened up a block buffering after the connection request success, as the data extra buffer;
Service end is set up an independently control section according to link separately simultaneously, is responsible for carrying out data interaction according to network state;
Concrete request of data is sent by client, and service end sends data, revises the Data Position of client when Data Receiving is finished, and guarantees the continuity of data;
Simultaneously, when network occur to postpone, client after the regular hour from a position send request again, prevent that data from being lost, realize the continuity of data.
Compared with prior art, the present invention has the following advantages:
1, do not need hardware supports, effectively reduce the cost of mobile phone end;
2, aspect program source, can expand automatically, demonstrate fully the program variation, the characteristics of no region limits;
3, adopt up-to-date compress technique,, promote the experience effect of mobile TV to the full extent at different handset processes abilities;
4, adopt self-defining host-host protocol, guarantee continuity and consistency in the data transmission procedure, effectively reduce byte nonessential in the transfer of data simultaneously.
