20、eces of equipment in an NTSC, PAL or SECAM high-resolution colour video system, in the form of a Y-signal, consisting of luminance + blanking + sync, and a C-signal, the same as the modulated chrominance signal of the composite video signal. It specifies the signal levels and impedances at the inter
21、face and the type of connector to be used.2 Normative referenceThe following normative document contains provisions which, through reference in this text, constitutes provisions of this International Standard.
