Difference between network matrix and decoder:
Traditional splicing screen in the past project is only the function of the display, and the signal wire is more complex is not easy to manage;
Network full-matrix splicing screen is also known as the DMD splicing screen, which is the display and control system into a single unit, replacing all the matrix, decoder, processor, etc., to facilitate the management and future upgrades. So the network full matrix is more applicable.
(1) "network matrix" is a video encoding software instead of analog matrix in the video input mode, digital high-speed processing CPU instead of analog switch, video decoding software instead of analog matrix in the video input module, network matrix host instead of the analog matrix host, based on the TCP / IP protocol IP network instead of the analog bus, the use of high-speed computer processing chips. Computing to complete the video from input to output switching equipment.
(2) decoder is a multi-input multi-output combinational logic circuits in electronic technology, is responsible for the binary code translated into a specific object, the function is the opposite of the encoder. Decoder is generally divided into two categories: general-purpose decoder and digital display decoder. In digital circuits, it can take the role of multi-input multi-output logic gates, which can convert coded inputs into coded outputs, where the inputs and outputs are coded differently. The input enable signal must be connected to the decoder to make it work properly, otherwise the output will be an invalid code word.
