摘要:

针对原始视频数据量大,不利于存储与传输的问题,设计了基于TMS320DM365的视频压缩传输系统。实现将多路输入的模拟视频转换为数字视频,在TMS320DM365中压缩编码并打包成TS码流。提供帧率、分辨率、P/I比等参数的设置功能,能适应于多种应用场景。实验结果表明,系统可实现25帧/s、D1分辨率标清视频的压缩传输,满足视频监控的需求

Abstract:

A video compression transmission system based on TMS320DM365 is designed, which is not conducive to the storage and transmission of the original video data. The multichannel analog video is converted into digital video with compressed encoding and packaged into TS standard stream in TMS320DM365. Setting of such parameters as resolution, frame rate, P/I ratio is provided for use in various application scenarios. Experimental results show that video compression transmission of 25 frames per second and D1 resolution is achieved, meeting the needs of video surveillance.

Key words: video compression, TMS320DM365, system circuit design
