    As analog TV still sends a B & W picture as well as colour (chromanance & lumanance) so as to remain backward compatible for B&W viewers (well back in the 70s anyway!), my question is....

    Does digital do the same or just send colour?

    Or is there more to it than that?

    Is a B&W signal still required in the processing for older colour TVs or can the STB handle all this processing?

    If it is a raw colour signal only then would standard VCRs benefit from having RGB recording capabilities?

    The native format of digital transmissions is, I believe, component in nature. Set top boxes have the ability to downconvert this to PAL encoded composite signals which are black and white compatible.

    If VCR's could record component signals from set top boxes it would be a benefit, yes.
