Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] In the present invention, the TV signal receiving decoder receives multi-channel TV signals, and converts one of the TV signals into streaming media (StreamingMedia, SM) signals according to the requirements of mobile terminals (such as mobile phones) for audio and video attributes, and then transmits them through wireless channels. To the mobile terminal, the TV signal is played in the mobile terminal. This playback method is independent of the TV, so it will not cause visual interference to other people watching TV programs through the TV, and can fully and effectively monitor and select ch...

Abstract

This invention provides a method and a system for playing multi-channel TV signals simultaneously, in which, said method includes: A, setting up wireless connection between a receiving decoder of TV signals and a mobile terminal, B, the decoder receives TV signals and transmits them to a mobile terminal after it processes them, C, the mobile terminal receives said TV signals and plays TV programs corresponding to the signals, in which, the decoder converts received TV signals to streaming-media signals according to the needs of a mobile terminal to audio-video attribute and sends them to a mobile terminal independent of the TV set via the wireless channel and plays it.

Description

technical field [0001] The present invention relates to the field of television and mobile communication, more specifically, relates to a method and system for simultaneously playing multi-channel television signals. Background technique [0002] Due to the rise of digital TV, TV signal receiving and decoding devices are well known. This device is a conversion device that converts digital TV signals into analog signals, decodes and restores digitally compressed image and sound signals, and generates analog video and audio signals. Sound signal, watch TV programs through TV. Typical TV signal receiving and decoding devices include set-top boxes, computers and digital TV all-in-ones, and the like. [0003] At the present stage, the TV signal receiving and decoding device can receive two channels of TV signals at the same time, so that the contents of the two channels can be played simultaneously. The playback method is realized by adopting the "picture-in-picture" method: on...
