Abstract: This paper contains a brief description of the RGB and the NTSC codecs used during the First SMPTE Component-Coded Demonstration of Digital Video. Each unit operates at the luminance/chrominance sampling ratio of 4:4:4 and is capable of running at any of three demonstration clock rates. Operating the above units in any tandem combination, as well as with a digital interface with units of the other Demonstration participants, yielded acceptable picture quality. In the Appendix the codec matrices between RGB, YUV, YIQ, and Y, R - Y, and B - Y of the digital interface are postulated. The relationship of Y, R - Y, and B - Y to the composite video signal is indicated. The numerical relationships described in this paper are independent of clock frequencies and luminance/chrominance sampling ratios.
