Universal high definition (HD) video signal collecting and coding device and data transmission method

Abstract

The invention relates to process of HD video signals, in particular to the process with presence of a plurality of different HD video signals, a transmission device and a method. The HD video signal collecting and coding device comprises a front processing portion and a rear processing portion. The front processing portion is composed of a data collector, a processor and a coder, wherein various information source decoders and IP collectors are integrated in the data collector, and the IP collectors are used for collecting the IP addresses of the information sources; the processors distribute corresponding the information source decoders according to the IP addresses; the coder compiles after decoding of the information source decoders; files are compiled and compressed according to the IP communications protocol standard, the data are transmitted out through a network cable, and the corresponding rear processing portion is arranged at the other end of the network cable. According to the universal HD video signal collecting and coding device and the data transmission method, transmission of all the information is achieved by one standard network cable when the plurality of video signals are transmitted.

Description

technical field [0001] The invention relates to processing of high-definition video signals, in particular to processing and transmission equipment under the condition that multiple different high-frequency signals coexist. [0002] The invention also relates to a transmission method of high-definition video signals, in particular to a method for simultaneous transmission of multiple different signals. Background technique [0003] In a large-scale monitoring system, the human-machine interface of the monitoring personnel is the digital large-screen display wall, and the signals that need to be displayed on the monitoring digital large screen include: remote high-definition IP digital video stream, local composite video signal, local analog computer RGB signal , Local digital computer DVI signal, local high-definition video signal. The traditional way is to use various special cables to transmit the signal to the image signal acquisition processor, and then display it on th...

Problems solved by technology

For example, when there are many kinds of external information, different transmission methods, different transmission standards, analog signals, digital signals, high-definition video, standard-definition video, etc. are used in the existing technology, so that the corresponding Equipped with different access devices, output devices, large and small devices, different lengths of wires, connectors with complete patterns, and superb and exquisite wiring skills; Proud, then, with the development of technology today, do we still live in such a complex "line" environment? Is there a way to reduce these wiring methods and reduce the wiring methods of information gathering points such as computer rooms, transfer stations, and monitoring rooms? That's the point of our invention
