Embodiment Construction

[0025] In the present invention, the front-end equipment of the digital TV system provides digital TV program sources, and one service in the program source includes multiplexed multiplexed videos. Since a service (Service) is only displayed as a TV program in an electronic program guide (Electronic Program Guide, EPG), a condition for realizing program hiding is provided.

[0026] The difference between the digital TV program source provided by the front-end equipment of the digital TV system of the present invention and the previous program source is that there are two or more channels of video data under one service. This requires a corresponding description of each channel of video in the Program MapTable (PMT) of the transport stream, that is, a PMT describes the packet identifier (Packet Identifier, PID) of multiple channels of video and multiple channels of audio.

[0027] Wherein, in the transport stream, the Program Map Table (PMT) of each service has a PID, denoted a...

Abstract

The invention discloses a method and equipment for processing multi-path video of digital television programs. The method comprises the following steps: analyzing a transport stream and acquiring audio data and video data corresponding to a television program which is selected by a user and multiplexes multi-path video data; popping up an interface for the user to select and process one path of video data when receiving a control instruction of selecting video sent by the user; and acquiring the video data selected by the user for decoding and output. The invention also discloses the method for providing of the multi-path video of the digital television programs. The method and the equipment adopt multi-path video multiplexing, provide a realizing condition for hiding the video data or the television programs and realize private data communication in a digital television system.

Description

technical field [0001] The invention relates to the processing of digital TV transport streams, in particular to a method for providing and processing multi-channel video digital TV programs and corresponding processing equipment. 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. Moreover, the digital TV operator provides multiple sets of TV programs, and the user can select different channels through the remote control to switch and watch the corresponding TV programs. [0003] In the MPEG-2 standard, regarding the multiplexing of multiple programs into Transport Streams (Transport Stream, TS), there is no strict regulation on the Elementary Stream (ES) contained in a service or service (Service), which is the The numbe...
