Design and implementation of video frame extractor for television broadcasting monitoring system

In this paper, a video frame extractor applying analog video input signals for television broadcasting monitoring system is designed and implemented in order to satisfy the requirements for rapid development of radio and television industry. The video frame extractor uses advanced RICS machine (ARM) embedded processor S3C2440A with Linux operating system as system host processor and field programmable gate array (FPGA) EP3C25 as system coprocessor, increasing the design flexibility and real-time performance. These extracted video images are compressed using a video encoder ADV212, and finally stored in local hard disks or transmitted to data servers through networks. In the verification chapter, the loop-locked experimental results under both normal and emergency modes demonstrate the validity and applicability of designed analog video frame extractor.
