The video A/D converters need a supply of properly amplified, limited, DC restored, clamped, clipped, contoured, multiplexed, faded and filtered analog video before they can accomplish anything. After the digital magic is performed, there is usually more amplifying and filtering to do as an adjunct to the D/A conversion process, not to mention all those pesky cables to drive. The analog way is often the most expedient and efficient, and you don’t have to write all that code.

The foregoing is only partly in jest. The experienced engineer will use whatever ...
