摘要

In this paper, a new source video signal is designed for online DVD evaluation and then its composite video signal waveform is produced through a video waveform generator board PXI-5431. The composite video field, no matter NTSC or PAL system it is, includes both visible image and invisible lines. The visible image has been set to different patterns, and the invisible lines include three lines such as Copy Once, Auto Clock Setting and Electronic Program Guide. Detailed procedures to produce both parts are well illustrated and the virtual instrument blocks in G-language are also presented.
