Abstract

The invention discloses a television set supporting a multi-program pattern. The television set comprises a signal source detection and preprocessing unit, a video playing unit, an audio playing unit and a main control unit, wherein the signal source detection and preprocessing unit is used for detecting the type of multiple types of television signals input into the television unit and separating audio signals and video signals from the television signals, the video playing unit is used for playing the video signals and sending synchronizing signals corresponding to the video signals to the main control unit, the audio playing unit is used for transmitting the audio signals through different frequency modulation channels, and the main control unit is used for transmitting the different frequency modulation channels, the corresponding relations between the different frequency modulation channels and the audio signals, and the synchronizing signals corresponding to the video signals to a plurality of glasses terminals. According to the television set supporting the multi-program patter, a plurality of programs can be played at the same time, the synchronizing signals and the audio signals can be transmitted in a separated mode, and the problems that communication distance is short and transmission is unstable are solved.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a television supporting multi-program mode, liquid crystal glasses, a television system and a control method. Background technique [0002] Existing digital TVs can obtain high-definition display images by combining the use of set-top boxes. However, users can only watch one channel through this TV. When it is necessary to watch multiple channels or videos at the same time, the existing TVs cannot satisfy For these requirements, users need to purchase multiple TV sets, which will cause waste of cost, space and energy. [0003] The Chinese patent with the application number 201110092113.5 discloses a "TV system that broadcasts different channels at the same time", which encodes the audio data of two TV channels and the synchronous control signal that is synchronized with the TV playback screen, and then adopts the method of infrared transmission The mixed transmission is sent ...
