Soft coding and decoding large-screen splicing system and soft coding and decoding method thereof

Abstract

The invention discloses a soft coding and decoding large-screen splicing system and a soft coding and decoding method thereof, the system comprises a video source, a switch, a network splicing controller, a transmitter and a splicing screen, the network splicing controller comprises a control management module, a network input module and a plurality of output modules, and the video source is provided with a splicing encoder. The data exchange between the video source and the network splicing controller is realized by adopting a network connection mode, the hardware configuration requirement on the video source equipment is reduced, a special video interface does not need to be arranged on the video source equipment, a corresponding video line does not need to be selected according to the interface, the expansion of the video source is facilitated, and the replaceability of the video source is improved. Meanwhile, the splicing encoder connected with the video source is used for encoding the video data, so that the video can be conveniently projected on the splicing screen to be displayed, and the requirement of the era of everything interconnection is better met.

Description

technical field [0001] The invention relates to the technical field of LED / LCD splicing screens, in particular to a soft coding and decoding large screen splicing system and a soft coding and decoding method thereof. Background technique [0002] The splicing screen is assembled and installed freely through several display units, and spliced ​​into a super large display screen. At present, splicing screens are widely used in many fields such as monitoring centers, command centers, and outdoor displays. see figure 1 , the current splicing screen system includes: several video sources, a splicing controller connected to the video sources, several transmitters connected to the splicing controller, and a large LED splicing screen connected to the transmitters. Provide video data through the video source, and send the video data to the splicing controller, splice or separate the video data, and finally transmit the processed video signal to the splicing screen through the trans...

AI Technical Summary

Problems solved by technology

If the video source does not have two video output interfaces, you need to configure an additional splitter to expand one interface into two interfaces. However, expanding the interface will cause more failure points of the equipment, reduce reliability, and increase construction costs. quantity and construction cost

[0004] 2. The types of video source devices are limited

If there is no HDMI, DVI, VGA, DP and other hardware interfaces on the video source, splicing cannot be realized
