4K high-definition receiving box and video output system thereof

Abstract

The invention discloses a 4K high-definition receiving box, and relates to the field of spliced screen KVMs. The receiving box is used for receiving and processing high-speed serial data transmitted by an optical fiber, and is characterized in that the receiving box comprises an FGPA processing module, an HDMI conversion chip and an audio conversion chip; the FGPA processing module converts high-speed serial data, outputs serial port data and analyzes and converts the serial port data into a high-speed differential serial 4K high-definition video signal and an audio signal, and the HDMI conversion chip restores the high-speed differential serial 4K high-definition video signal and expands the high-speed differential serial 4K high-definition video signal into a plurality of HDMI high-definition videos to be output; the audio conversion chip restores and expands audio signals into a plurality of audios, one or one group of high-speed serial 4K data are output as a plurality of HDMI high-definition video outputs and audios, the high-speed serial data transmitted by the optical fiber are analyzed, high-definition video streams are converted into low-delay lossless 4K high-definition HDMI outputs, and the audio stream is converted into a lossless analog audio signal.

Description

technical field [0001] The present invention relates to the field of splicing screen KVM, and more specifically, to a 4K high-definition receiving box and a video output system thereof. Background technique [0002] With the continuous development of audio and video industry technology, people have higher and higher requirements for video image quality, and the demand for low-latency and high-quality video transmission technology is increasing; most of the existing video transmission on the market is based on H264 / H265 lossy compression methods For transmission, there are disadvantages such as high delay and lack of video quality. Contents of the invention [0003] The invention aims to overcome the traditional H264 / H265 lossy compression method, provide a 4K high-definition receiving box and its video output system, and realize low-latency and high-quality 4K video reception. [0004] The technical scheme that the present invention takes is, [0005] A 4K high-definitio...
