Problems solved by technology

On the contrary, if only the socket of the audio signal or video signal transmission channel is set, when the user wants to switch the operation mode, for example: the user wants to switch the original listening or talking action to the action of viewing the image, the user will will not be able to perform its operation because it does not have the required socket

Embodiment Construction

[0018] figure 1 It is a schematic block diagram of a switching system for video signal transmission and audio signal transmission according to an embodiment of the present invention. The switch system 100 includes a transmission line socket 104 , a discrimination circuit 106 , a central processing unit 108 and a switch 110 . The transmission line socket 104 is used for coupling a transmission line plug 102 . The discrimination circuit 106 is electrically coupled to the transmission line socket 104, and when the transmission line plug 102 is coupled to the transmission line socket 104, it determines whether the transmission line plug is a video signal transmission line plug or an audio signal transmission line plug, and then generates a discriminant signal. The central processing unit 108 is electrically coupled to the judging circuit 106 to receive the judging signal generated by the judging circuit 106 to control the switching action of the switch 110 . The switch 110 is e...

Abstract

The invention relates to a method for switching between video signal transmission and audio signal transmission, and aims to solve the problem that a single socket can only provide a single transmission wire plug for use. The switching method comprises the following steps of: judging whether the transmission wire plug is a video signal transmission wire plug or an audio signal transmission wire plug; producing a judgment signal according to a judgment result; controlling a switch according to the judgment signal; and switching a transmission channel into a video signal transmission channel oran audio signal transmission channel through the switch so as to perform signal transmission of the video signal or the audio signal. Therefore, a user can perform different signal transmission operations by only directly replacing different transmission wires. Furthermore, the invention also discloses a system for switching between video signal transmission and audio signal transmission.

Description

technical field [0001] The present invention relates to a system and method for switching signal transmission channels, and in particular to a system and method for switching video signal transmission and audio signal transmission. Background technique [0002] Generally, when users use earphones or microphones to transmit sound signals, they usually couple the transmission line plug of the earphones or microphones to the socket of the audio transmission channel, so as to listen or talk. In addition, when the user wants to watch the video, the plug of the transmission line of the video must be coupled to the socket of the video signal transmission channel separately, so as to watch the video. [0003] However, in this way, when the user only needs to transmit the audio signal or the video signal, another unused socket will be left unused, resulting in a redundant situation. Therefore, in the case that the user only needs to transmit audio signals or video signals, it is not...
