Abstract:

An apparatus for adaptively generating video signal thresholds for a comparator circuit having a plurality of signal channels. The apparatus has input circuitry in electrical signal communication with the plurality of signal channels. The input circuitry uses a selector circuit to select one signal channel of the plurality of signal channels for processing. The apparatus also has a processing resource having an input joined to process the electrical signals on the selected one signal channel to determine if a video signal is present and, if no video signal is present to process noise signals on the selected one signal channel to generate a new video signal threshold. The processing resource has an output to provide the new video signal threshold to the comparator circuit corresponding to the selected signal channel.
