Abstract

The invention discloses a multi-channel video acquisition and processing device for teaching, comprising a video processing module (VPSS), a video input module (VI), a video output module (VO), a video encoding module (VNEC), and a video decoding module (VDEC), the video processing module is electrically connected with a video input module, a video output module, a video encoding module, a video decoding module, a video multiplexing module and a demultiplexing module, respectively, and the video processing module is connected with a video distribution amplifier, so The video input module includes an SDI video capture chip and a VGA capture chip, and the encoding module includes a rate controller (RC) and an encoder (Encoder). The equipment has low cost, simple construction and small maintenance workload.

Description

technical field [0001] The invention relates to a multi-channel video collection and processing device and method for teaching. Background technique [0002] PC-style audio and video capture needs to insert the capture card into the PCI / PCI-E slot of the PC. Since it is an interface, of course there will be a problem of loose interface; in addition, the gold finger of some capture cards (PCI / PCIE interface part) There is also the problem of poor contact caused by oxidation; while in the embedded mode, all chips are soldered to a fixed board, and there is no problem of loosening and oxidation of the interface, so its shock resistance and dustproof function will be better. From the perspective of software, embedded is mainly reflected in the fact that the operating system is not easily affected by some additional factors, and the WINDOWS operating system carried by the PC itself has instability and other adverse factors caused by additional functions, as well as Compatibility...
