DigiSuite, analog component video refers to a
signal containing three channels: Y (luminance),
R-Y (red minus luminance), and B-Y (blue minus
luminance).
composite video A video signal containing
luminance and chrominance information that has
been combined using a video standard such as
NTSC or PAL.

both NTSC and PAL sources to give enhanced
chroma resolution. It uses a 1/2” metal particle
tape.
