Abstract

The invention discloses a high-definition matrix capable of realizing remote synchronous transmission of multichannel high-definition videos. The high-definition matrix comprises a master control board which is connected with at least two high-definition video encoding-decoding boards; the master control board and the high-definition video encoding-decoding boards are powered by a power module; when video acquisition is performed, the at least two high-definition video encoding-decoding boards collect, compress and code audio data, video data or the audio data and the video data at the same time by an audio-video acquisition interface; and then, the compressed and coded data are transmitted to the master control board; the master control board is provided with an independent network interface; and the data are multiplexed by the master control board and repacked to send out by the independent network interface. As a mode based on an IP (Internet Protocol) network is adopted for accomplishing remote transmission of the high-definition videos, the remote transmission of high-definition video signals can be ensured without distance limitation, and the definition of the video signals and the playing effect can be ensured simultaneously; and moreover, the cost can be greatly reduced and revolutionary breakthrough can be provided in the technology.

Description

technical field

[0001] The disclosure of the invention relates to the field of video and audio codec and information transmission, and discloses an information recording and dissemination product, in particular a high-definition matrix capable of realizing long-distance synchronous transmission of multi-channel high-definition video. Background technique

[0002] At present, in the field of video transmission such as monitoring and video conferencing, the transmission of multi-channel high-definition signals is basically carried out in the form of high-definition matrix. Each channel of video needs a video cable, and there are as many video channels as there are video signals. When it exceeds a certain distance, it will encounter the following problems: 1. The high-definition video cable has a distance limit, and the cost is very high after a certain length; 2. The signal attenuation is severe, resulting in poor playback effect on the player; 3. , It is impossible to realize...
