Method and system for implementing IPTV multi-format mixed channel time shifting

Abstract

The invention discloses a method for realizing the time shifting of an IPTV multi-format blending channel, comprising the following steps that: a stream server sends a multi-format program stream to a client, the multi-format stream carries an ID number of the program; the client obtains an audio video decoding parameter according to the ID number of the program carried by the multi-format program stream; the client initializes a decoding module according to the audio video decoding parameter and controls a play module to play the multi-format program stream. Accordingly, the invention also provides a system for realizing the time shifting of the IPTV multi-format blending channel. Therefore, the invention can eliminate the limit that only a source with same audio video decoding parameters can be played on the same time shifting channel, thereby realizing the time shifting of a channel combined by a source component with different formats.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an IPTV (Internet Protocol Television, interactive network television) multi-format hybrid channel time-shifting realization method and system. Background technique [0002] With the continuous application of IPTV (Internet Protocol Television, Interactive Network Television) technology, the traditional "passive viewing" mode of analog TV has been greatly changed. The advantages of the network enable the real realization of "interactivity". [0003] IPTV is a technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. Users can enjoy IPTV services at home in the following two ways: (1) computer; (2) network set-top box + ordinary TV. [0004] The stream server sends the program stream to the client such as STB (Set-Top Box, set-...

AI Technical Summary

Problems solved by technology

If the system and the terminal itself do not support this mixed channel, it is necessary to re-compress the film source to maintain the consistency of various parameters such as encoding format, video aspect ratio, number of audio channels, sampling rate, etc., and re-compression not only It will lose the quality of audio, video and video, and consume a lot of manpower and financial resources

[0006] In summary, the existing IPTV multi-format hybrid channel time-shifting technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
