-- each primary is sent as a separate video signal.
- The primaries can either be RGB or a luminance-chrominance transformation of them (e.g., YIQ, YUV).
- Best color reproduction
- Requires more bandwidth and good synchronization of the three components
-- color (chrominance) and luminance signals are mixed into a single carrier wave. Some interference between the two signals is inevitable.
(Separated video, e.g., in S-VHS) -- a compromise between component analog video and the composite video. It uses two lines, one for luminance and another for composite chrominance signal.
