发明名称 VIDEO TIME BASE CORRECTOR
摘要 <p>A time base corrector converts incoming video or other periodic information to digital form in an A/D converter, and writes the digitized signals in a memory at a clocking rate determined by a write clock generator in accordance with time base errors in the incoming signals, whereupon the signals temporarily stored in the memory are read out, or fetched therefrom at a standard clocking rate determined by a read clock generator and reconverted to analog form in a D/A converter for eliminating the time base errors. The memory is composed of a plurality of cyclically enabled memory units which each have a capacity to store information for two or any other even number of line intervals of the video signals. Each memory unit will have the same number of words to be written therein and to be fetched therefrom for facilitating the sequence control of the memory, even though alternate lines of the video signals, as written in the memory, may be comprised of different numbers of words.</p>
