Abstract

The embodiment of the invention provides an audio data transmission method, device, system and equipment. The method comprises the steps of adding to-be-transmitted audio data to a blanking region ofa video frame, obtaining the video frame carrying the audio data, and transmitting the video frame carrying the audio data. According to the scheme, a communication cable for transmitting the video frame is used for transmitting the audio data, additional wiring for the audio data is not needed, and the wiring cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of signal transmission, in particular to an audio data transmission method, device, system and equipment. Background technique [0002] In the monitoring system, the front-end camera is connected to the back-end processing device through a communication cable (such as a coaxial cable or other cables), and the front-end camera sends the collected image to the back-end processing device through the communication cable. The back-end processing device can store, play and process the received images. [0003] In some cases, an audio device is also set up in the scene, and audio data is transferred between the audio device and the back-end processing device. In most current solutions, an audio cable is additionally arranged between the audio device and the back-end processing device, and audio data is transmitted through the audio cable. This solution increases wiring costs. Contents of the invention ...
