Abstract

This invention relates to an audio-and-video signal processing device, a playing device, a system and a method. The audio-and-video processing device is used for connecting to one or more than one audio-and-video signal playing devices. The audio-and-video signal processing device comprises an audio-and-video signal acquisition unit, an audio-and-video signal processing unit and an audio-and-video signal transmission unit. The audio-and-video signal acquisition unit is used for collecting one or more than one external audio-and-video signals; the audio-and-video signal processing unit is used for processing the collected audio and video signals and the processing comprises the IP processing. The audio-and-video transmission unit is used for outputting the audio and video signal which has gone through the IP processing in an IP broadcasting manner. The audio-and-video signal processing device, the playing device, the system and the method provided by the invention reduces the cost for upgrading and updating of the television and eliminates the repeat investment on the resource equipment.

Description

technical field [0001] The present invention relates to an audio and video technology, especially an audio and video signal processing device, playback device, system and method (including an audio and video signal processing method, an audio and video signal playing method, and an audio and video system implementation method). Background technique [0002] It is well known that TV sets are inseparable from external signal cables, so where the TV signal line is, the TV set has to be placed there, otherwise, the TV signal line has to be extended to the side of the TV set, which is extremely inconvenient to use; The signal cable can only be connected to a single TV, so for the scenario of multiple rooms and multiple TVs, repeated investment in source equipment is inevitable; the TV has developed from CRT TV to LCD TV, and its role is not only to watch TV programs have also become an inseparable part of home decoration. Although the LCD TVs produced by TV manufacturers all have...
