Method, system and storage device for collecting and distributing multi-channel audio and video signals

Abstract

The invention discloses a multi-channel audio and video signal acquisition and distribution method and system as well as a storage device. The multi-channel audio and video signal acquisition and distribution method includes the following steps: detecting the number of signal acquisition equipment and signal output equipment in all lines, and numbering all signal acquisition equipment and signal output equipment; and then enabling each signal acquisition equipment to acquire corresponding audio and video data, and saving the corresponding audio and video data to a data table with a preset structure according to the serial numbers of the signal acquisition equipment; and then reading the audio and video data in the data table according to a preset signal distribution rule, and outputting the corresponding audio and video data to the signal output equipment with the corresponding serial numbers. Thereby, the real-time distribution of multi-channel audio and video signals can be implemented, and the acquisition and distribution efficiency of the multi-channel audio and video signals can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of embedded signal processing systems, in particular to a method, system and storage device for collecting and distributing multi-channel audio and video signals. Background technique [0002] With the development of the Internet of Things, the embedded video acquisition system has the advantages of high efficiency, small size, real-time stability, and low cost, and has naturally become a good carrier for video surveillance equipment. However, most of the existing embedded devices adopt the method of switching input devices for the collection and output of audio signals, such as Android tablets, etc., and in terms of function, they can only switch and play one of the multiple channels, and cannot do more. Simultaneous distribution of audio and video.

However, most of the existing embedded devices adopt the method of switching input devices for the collection and output of audio signals, such as Android tablets, etc., and in terms of function, they can only switch and play one of the multiple channels, and cannot do more. Simultaneous distribution of audio and video

If you want to support the acquisition and output of multi-channel audio and video signals at the same time, you need multiple embedded devices to work together to build a communication network to meet the needs, which wastes a lot of embedded resources, and the entire signal distribution system will appear very Complicated and difficult to maintain
