What is the difference between video decoder and video decoding matrix?

The difference between a video decoder and a video decoding matrix is that the video decoder decodes the signal onto the wall and uses software to control the image. The decoding matrix has decoding functions, picture segmentation functions, storage functions, switching functions, and also uses software to control the image. For small and medium-sized projects, it is more cost-effective to choose a video decoder, which is used in the radio and television, medical, and education industries. Large-scale projects have requirements for network bandwidth, splicing display, video control, etc. Video matrix is mainly used in the security large-scale project industry.

With the development of audio and video transmission technology, all walks of life need to rely on network technology to achieve unified viewing of video sources from cameras. From early analog monitoring to current network digital monitoring. It has also become the core of current security monitoring projects or unified management and monitoring of videos. Recently, many friends have been asking about the difference between a video decoder and a video matrix. Which solution should I choose for video on the wall? Today I will give you some popular science.

For surveillance systems, the function of a video decoder is to compress large video information and then transmit it in wired or wireless network communications. The compressed video information will be much smaller than the original one, reducing the video The transmission time is then decompressed on the terminal, and the decompressed video can be clearly displayed on the screen. If you want high-definition and low-latency video surveillance, of course, this high-definition video codec is a must-have device.

So how is the video decoder used:

For example, if there are 8 1080P cameras at the front end, and they need to be divided into 8 different images to be displayed on the large screen, they need to be equipped with a decoder that supports 1080P cameras. At the same time, the decoder must be capable of being displayed on 8 different screens. Video decoding matrix Video decoding matrix is also a decoding device that decodes front-end digital video signals and puts them on the wall. The input end of its signal is a Gigabit network port, which can be directly connected to the display screen or to the splicing controller. The video decoding matrix is actually multiple decoders integrated together. The functions of both are the same, converting digital signals into analog signals and sending them to the wall.

The difference between video matrix and video decoder

The decoder decodes the signal and puts it on the wall, and uses software to control the image. The network decoding matrix controls multiple physical screens at the same time, and decodes and outputs multiple channels to switch to different display screens or splicing screens. The digital matrix has decoding function, picture segmentation function, storage function, switching function, and also uses software to control the image. Generally, for small and medium-sized projects, it is more cost-effective to choose a video decoder. Mainly used in the radio and television industry, medical industry, education industry, etc. For large-scale projects, there are requirements for network bandwidth, splicing display, video control, etc., so the video matrix is mainly used in the security large-scale project industry.
