Abstract

The invention discloses an IPTV system, an audio / video coding switching method and equipment, wherein the audio / video coding switching method comprises the following steps of: analyzing out multiple paths of audio code streams and video code streams in different coded formats of a current television program from a received transport stream and respectively storing the code streams to an audio code stream database and a video code stream database; when an indicator signal sent by a user for selecting an audio coding format or a video coding format is received, controlling to acquire an audio code stream and a video code stream with coding formats corresponding to the coding format of the indictor signal from the audio code stream database or the video code stream database and controlling to transmit the video code stream and the video code stream to a decoder for processing. The invention provides a favorable condition for users to customize a digital television service, and the users can select different audio coding formats according to different use environments or external equipment so as to achieve a better digital television watching effect.

Description

technical field [0001] The present invention relates to audio and video processing technologies, in particular to a method for encoding and switching audio and video, corresponding processing equipment, and an IPTV system using the method. Background technique [0002] In the process of continuous development and popularization of digital TV, in order to meet different customer needs, it is necessary to provide customers with more and better service content, and even provide service content selected by customers according to their own needs. [0003] Digital TV operators provide multiple sets of TV programs, and users can switch to watch corresponding TV programs by selecting different channels through a remote control. At the same time, since the TV program data contains audio data of different channels, the user can select different channels through the remote control to produce different audio-visual effects under different environments and conditions when watching TV pro...
