Abstract

The invention provides an uplink transmission method and a downlink transmission method for an ultra-high-definition video signal, and the method comprises the steps: carrying out the coding of a collected ultra-high-definition video signal, and obtaining a coded signal; modulating the coded signal according to the working frequency band of a target satellite transponder to be used to obtain a modulated signal; performing power amplification on the modulation signal to obtain a power-amplified modulation signal; and transmitting the modulation signal after power amplification to a target satellite transponder through a preset antenna, so that the target satellite transponder forwards the modulation signal after power amplification. The transmission quality and the transmission efficiency of the ultra-high-definition video signal are improved, and efficient transmission and further application of the ultra-high-definition video signal are facilitated.

Description

technical field [0001] The invention relates to the technical field of video information rebroadcast transmission, in particular to an uplink transmission method and a downlink transmission method of ultra-high-definition video signals. 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 line...
