Implementation of Video Capturing and Playing-back in Embedded System
JU Zheng-quan · Microcomputer Information · 2008
The amount and quality of video information is increasing rapidly in embedded system. But the rate of real time video capturing based on USB 1.1 technique is not satisfied in the meeting of the increasing demands of capturing and playing-back fluently. This paper presents a video capturing and playing system based on embedded processor S3C2440A and co-processor SM501, analyses the working principle of hardware architecture and software module in the details. A common designing method of embedded video system is brought forward, and then a real demo system is implemented also in this paper.
