Method for supporting watching two-path video and network interaction television system

Abstract

The invention discloses a method for supporting watching two-path video and a network interaction television system. The method comprises that: two-path video stream comprising live main video code stream and picture-in-picture video code stream is introduced into each live channel on a server side, and a corresponding relationship is established between the main video and the picture-in-picture video of the same live channel; when the picture-in-picture function is started, a set-top box requests an EPG server for opening a channel information superposition page with a picture-in-picture window; the EPG server transmits the channel information superposition page to the set-top box, and provides address link information and display position information of a streaming media server for playing the corresponding picture-in-picture video; and the set-top box acquires the corresponding picture-in-picture video code stream through interaction with the appointed streaming media server, decodes the picture-in-picture video code stream and displays picture-in-picture video programs at the appointed window position. Through the method and the system, a user knows and browses the play information and play video of other channel programs when watching the main video program.

Description

technical field [0001] The invention relates to the field of Internet Interactive Television (IPTV), in particular to an IPTV system and a method for displaying channel information with a picture-in-picture function while playing a main video in the IPTV system. Background technique [0002] With the continuous development of computer network technology, the application of IPTV system has been rapidly developed and promoted. The set-top box is the main terminal equipment in the IPTV system, which provides interactive TV and various value-added services to users through the IP data network. The advantages of TV are more and more superior to traditional digital TV. How to use this advantage to improve user experience and win more customers has become the focus of attention of major manufacturers. [0003] While the user is watching TV programs, other channel information pages are provided for the user to check. This function is extremely useful when the current channel is beco...

Problems solved by technology

[0004] At present, there are two main types of simultaneous display technologies for two-way video in TV applications. One is the picture-in-picture function of the TV itself. This kind of TV needs to support the reception of two-way video from the hardware circuit, and the cost is high. , after the current TV programs are converted into digital TV, the original TV only plays the role of a display, and the picture-in-picture function in the original TV can no longer be used in this case; another realization It uses the program source to synthesize two channels of video programs into one channel of video on the encoder side. This implementation method cannot achieve random matching of any two channels, and the implementation of the source encoder has relatively large restrictions on functions.
