Abstract
A method of transmission of wide bandwidth chroma signals converts a component video signal having a luminance and two half-bandwidth chroma components into a 0:4:4 video signal having no luminance component and two wide bandwidth chroma components. Half of the wide bandwidth chroma component samples are inserted into a standard serial digital data stream in place of the luminance component, and the second half of the wide bandwidth chroma component samples are inserted into the standard serial digital data stream in place of the two half-bandwidth chroma components.
