Video encoder and control method thereof

Abstract

The invention relates to a video encoder and a control method thereof. The video encoder comprises a power supply circuit, an FPGA chip, a first compression unit, a second compression unit and a communication interface. The FPGA chip performs data transmission with the first compression unit and the second compression unit respectively and communicates with peripheral equipment through a communication interface. The peripheral equipment comprises a computer user terminal and a Camera Link camera. The FPGA chip receives a video from the Camera Link camera and transmits the video to the first compression unit or the second compression unit for video compression, and the computer user terminal achieves automatic switching between the first compression unit and the second compression unit by controlling the FPGA chip and feeds back the compressed video to the computer user terminal. According to the invention, manual control is effectively reduced, the problem that scene monitoring cannotbe kept continuous during input image switching is solved, and the influence of frame loss or frame error is reduced to the maximum extent when data overflow occurs through a transmission anti-congestion function.

Description

technical field [0001] The present invention relates to the technical field of video transmission, in particular to a video encoder and a control method thereof. Background technique [0002] A video encoder is a functional hardware device that compresses the original captured or captured video. With the continuous development of audio and video and the upsurge of live broadcast, video encoders are very important in our lives. At present, it is widely used in the broadcasting industry (TV live broadcast, network live broadcast), communication industry (video conferencing, network security monitoring), medical industry (digital medical care, remote teaching), education industry (distance teaching, resource sharing, teaching recording and broadcasting), etc. And so on are inseparable from the video encoder transmission technology. The main function of the video encoder is to directly encode the video information captured by the camera and then push it to the network server or...
