Appendix B Video Waveforms
This appendix illustrates the NTSC video waveform and is taken from EIA/TIA 250C, an earlier version of which formed the basis for the video waveform as specified in the FCC rules for broadcast television. See Chapter 2 for a more detailed description of the NTSC video waveform. The figures as shown in this appendix are drawn to conform as closely as possible to the defined amplitude and times of the NTSC signal. Other references frequently distort the time relationships.
The basic frequency in an NTSC waveform is the color subcarrier. All other video frequencies are defined in terms of the color subcarrier and for broadcast purposes are required to be locked to the subcarrier. The color subcarrier frequency is defined ...
