Problems solved by technology
In practical applications, users are generally accustomed to displaying video signals through active decoding. However, due to the inconsistency in viewing frequency of different video sources, active decoding is always used for video with low frequency viewing and video sources with tight video signal output. Mode display will put pressure on background services and old signal transmission equipment, resulting in unstable signal output

Embodiment Construction
[0012] The present invention uses a high-definition decoder, a large-screen display, a decoding wall client software module, a video integrated machine and other software and hardware systems to carry out comprehensive work to ensure that after video signals from different sources are input to the decoder, after the mode setting of the decoder and the main , Passive decoding channel settings, thus completing the solution of outputting video signals to the large-screen display area for display.
[0013] figure 1 Indicates the interactive working relationship among the video all-in-one machine, client software system, decoder, and large-screen display.
[0014] Among them, the video all-in-one machine forwards the video stream to the decoder and client through internal protocol instructions such as streaming media forwarding service, central media scheduling service, and video equipment control service;
[0015] The client provides a graphical interface for command interaction ...

The invention discloses an active / passive interactive decoding display method based on a high-definition decoder. The active / passive interactive decoding display method is characterized in that a high-definition decoder, a large-screen controller, a decoding on-wall client and a video integrator are used for performing comprehensive work in order to ensure that video signals from different sourcesare input into the decoder, the mode setting of the decoder, an active decoding channel and a passive decoding channel are provided, and a solution of displaying a video signal to a large-screen display area. The video integrator is used for forwarding a video stream to the decoder and the client through the stream media forwarding service, a center media scheduling service, a video equipment control service. The decoding on-wall client is used for providing a graphic interface, and interacts with the video integrator, the decoder and the large-screen controller. The high-definition decoder is used for acquiring a video signal from the video integrator, and outputting the video to the large-screen controller through a signal cable. The large-screen controller is used for receiving a client software command for partitioning the screen, and acquiring the signal from the decoder for displaying.
Description
technical field [0001] The invention relates to the technical field of monitoring video display, in particular to a video decoding and display method based on a high-definition decoder. Background technique [0002] It is a common application mode in daily monitoring to output the video signal from the decoder to the large-screen display. The decoding display is mainly divided into active decoding and passive decoding. Among them, active decoding is also called dynamic decoding, and fast decoding is realized by pre-setting the associated front-end device information. Passive decoding means that the decoder passively receives the code stream for decoding and transmission. Generally speaking, the active decoding method should be used for video signals with stable signal sources, and the passive decoding method should be used for displaying on the screen for video sources with tight video signal output. In practical applications, users are generally accustomed to displaying ...
