Video time base corrector

A time base corrector for processing television signals to remove time base errors introduced during signal recording, reproducing, or transmission. Incoming video signals are converted from analog to digital form and temporarily stored in a memory unit. Time base errors are removed from the video signals by storing the digitized signals at a clocking rate which varies in a manner generally proportional to the time base errors and fetching these stored signals at a standard clocking rate. The clocking signal for storing the digitized information is derived from an input voltage controlled oscillator whose frequency is dependent upon the frequency content of the instantaneous incoming video line information; the clocking signal for fetching is derived from a frequency standard. After storage and retrieval, the digitized video information is reconverted to analog form, processed and coupled to an output terminal.
