The normal interpretation of a component video signal is one in which the luminance and chrominance remain as separate components, e.g. analogue components in Betacam VTRs, digital components Y, Cr, Cb in ITU-R BT.601 and 709. RGB is also a component signal. Pure component video signals retain maximum luminance and chrominance bandwidth and the frames are independent. Component video can be edited at any frame boundary.
