Abstract

The invention discloses a multi-channel video processing switcher and a measuring method thereof. The multi-channel video processing switcher comprises a channel detection module, an LED control display module, a key analysis module, a function selection module, a switching control module, an AD8175 control module, an AD9984 control module, a video data collection module, a DDR3 control module, a multi-screen display module, a character generation and addition module, a four-side eight-mode correction module and a video output module. According to the invention, random seamless switching output display among multiple paths of input sources can be realized, video fusion processing of the multiple paths of input sources is realized, and trapezoidal correction operation of'four sides and eight modes' on the output video stream is realized.

Description

technical field [0001] The invention relates to the technical fields of high-definition digital video signal processing and high-speed signal exchange, in particular to a multi-channel video processing switcher and a measurement method thereof. Background technique [0002] Video is an important carrier of visual information, accounting for about 70% of the total information people get, and their attention is increasing day by day. With the development of high-definition digital video processing technology and high-speed signal switching technology, and the improvement of people's quality of life, people have higher requirements for visual effects. There are more and more functional requirements for video processing equipment used with laser projectors; at present, it has not been able to realize arbitrary seamless switching between multiple input sources, output display, video fusion processing of multiple input sources, and output control. A high-performance, all-in-one d...
