Audio and video matrix

Abstract

The invention provides an audio and video matrix which comprises a case body. The case body comprises a bottom plate, a top plate, a front plate, a rear plate and two side plates, the rear plate is provided with a plurality of aviation interfaces, and the front plate is provided with an indicator lamp, a display panel and a control key. A power supply module, a filter, a fuse, a video input module, an audio input module, a video output module, an audio output module and an audio and video switching and control module are arranged in the case body. Reinforcing ribs are arranged in the case body, all faces of the periphery of the case body are fixed through the reinforcing ribs, and therefore low-frequency resonance can be effectively avoided, an aviation interface is adopted outside the case body, the poor contact phenomenon in the vibration process is effectively eliminated in an aviation plug connection mode, and through the arrangement, the low-frequency resonance can be effectivelyavoided. Therefore, the audio and video matrix has the effects of impact resistance and vibration resistance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an audio and video matrix. Background technique [0002] The existing audio and video matrix is ​​mainly used in conference rooms on land. Its main function is to access video signals of various interface protocols. The video input interface can be connected to HDMI, DVI, VGA, CVBS, IP, SDI and other types of For video signal, there will be a 3.5mm audio input interface next to the video input interface, and the output terminal can also provide HDMI, DVI, VGA, CVBS, IP, SDI and other types of video output signals, and there will also be a 3.5mm audio output interface, through the corresponding software, a certain video and audio mixed signal at the input end can be switched to any video and audio output at the output end. The video and audio signals at the input end are bound together and switched synchronously. Asynchronous switching is performed, and the audio signal has...

AI Technical Summary

Problems solved by technology

[0003] At present, the audio and video equipment on the market is mainly used in the conference room on land. The environmental conditions of the conference room (including temperature, humidity, air salinity and pH, etc.) are very good. Equipment under good environmental conditions, but in some special environments, such as in the ship field, during the operation of the ship, the turbulence is strong, and it is often impacted, and the existing audio and video matrix devices on the market are not up to the job
