Abstract

The invention provides a video rebroadcasting system and a video receiving system, and the method comprises the steps: enabling coding equipment in the video rebroadcasting system to code a received ultra-high-definition video signal, obtaining an ultra-high-definition video TS flow signal, and transmitting the ultra-high-definition video TS flow signal to signal frequency conversion modulation equipment; enabling the signal frequency conversion modulation equipment to carry out modulation and frequency conversion on the received ultra-high-definition video TS stream signal to obtain a processed TS stream signal; wherein the signal power amplification equipment is used for carrying out power amplification on the processed TS stream signal to obtain a power amplification signal; and enabling the waveguide device to transmit the power amplification signal to a satellite transmitting antenna, so that the satellite transmitting antenna transmits the power amplification signal to a satellite for forwarding use of a transponder on the satellite. And after the ground receives the signals forwarded by the satellite, frequency conversion power amplification, demodulation and decoding are carried out, and ultra-high-definition video signals are recovered to be played or recorded. According to the invention, the transmission efficiency of 8K ultra-high-definition video signals is improved.

Description

technical field [0001] The invention relates to the technical field of satellite rebroadcasting, in particular to a video rebroadcasting system and a video receiving system. Background technique [0002] According to ITU-R BT.2020 "Ultra High Definition Television System Program Production and International Exchange Parameter Values" and GY / T307-2017 "Ultra High Definition Television System Program Production and Exchange Parameter Values", the resolution of ultra high definition images The rate is 3840×2160 and 7680×4320, which are commonly known as 4K and 8K. From the perspective of a TV terminal, a TV that can receive, process and display UHD programs is called an UHD TV. The resolution of the 4K ultra-high-definition TV screen is 3840×2160 pixels, and the definition can reach 2160 TV lines. The resolution of the 8K ultra-high-definition TV screen is 7680×4320 pixels, and the definition can reach 4320 TV lines. For ultra-high-definition video transmission, according to ...
