Problems solved by technology

However, when the user switches the viewing channel through the buttons on the 3D glasses, the audio received by the earphone cannot be automatically switched to the audio of the target viewing channel. To switch to the audio of the viewing channel, the user needs to manually press the button To achieve, or by replacing the 3D glasses to achieve the synchronization of TV video and TV audio, the user operation is extremely inconvenient

Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0037] refer to figure 1 , figure 1 It is a working principle block diagram of a preferred embodiment of the device for dual-channel TV video and audio synchronization in the present invention. The device for synchronizing video and audio of a two-channel TV of the present invention includes a 3D TV 1 , 3D glasses 2 and earphones 3 .

[0038] Specifically, when the 3D TV 1 enters the dual-channel working mode, it will simultaneously send out the 3D synchronous signal and the audio of two viewing channels (channel 1, channel 2), wherein the 3D glasses 2 receive the 3D synchronous signal, and the earphone 3 receives the 3D synchronous signal. Audio on channel 1 or channel 2....

Abstract

The invention discloses a method and a device for two-channel television video and audio synchronization, wherein the method for two-channel television video and audio synchronization comprises the following steps that: a pair of 3D (three-dimensional) glasses judges whether a video watching mode of a 3D television is a 2D (two-dimensional) watching mode; if so, the pair of 3D glasses outputs an audio switching command to an earphone when the 3D television switches to a target watching channel from the current watching channel; and the earphone receives the audio of the target watching channel according to the received audio switching command. In the method, when switching the watching channel, the 3D glasses can automatically control the earphone to switch own audio receiving from the current watching channel to the target watching channel, in this way, the automatic synchronization between the television video watched by a user and the television audio heard by the user is realized.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a method and device for synchronizing video and audio of a two-channel television. Background technique [0002] With the improvement of 3D TV technology, the application of TV is getting wider and wider. With traditional TV, when two people watch one TV at the same time, they can only watch the same program. However, with the application of 3D TV technology, two people can watch different TV programs at the same time, for example, one person watches a satellite TV station while the other watches a movie station; game. When playing a two-player game, the TVs in the past used left and right split screens or up and down split screens to play their respective game content. However, through 3D TV technology, the original need for two TVs becomes only one TV. Everyone can see the game content in full screen. [0003] When two people watch a TV at the same time, because the exis...
