Abstract
A color television signal, digitized by a sampling clock asynchronous with respect to the television signal's horizontal synchronizing pulses, is applied to a dynamically programmable digital filter which upsamples or downsamples the received digitized television signal over short time periods in response to time-base disturbances in the signal. The user may also select a higher or lower long-term clock frequency. Resampled digital samples are applied to a FIFO memory for readout at a clock rate which follows the time-averaged horizontal frequency of the received digitized television signal, or, alternatively, at a substantially fixed clock rate, asynchronous with respect to the horizontal line frequency of the received digitized color television signal.
