ABSTRACT:
An apparatus for providing component-to-composite and vice versa transcodings of a sampled video signal features generating steering bits that indicate which of combinations of surrounding samples of a composite signal has a component that provides the closest match to the corresponding component of an original component video signal. This allows successive transcodings with a minimum of crosstalk between components, e.g., luminance and chrominance.
