ABSTRACT A digital time base corrector for correcting time base errors of the digital samples of a video signal for all the various speed modes of a reproducing apparatus. The time base corrector is configured having a small capacity memory and a large capacity memory wherein the small capacity memory is divided into a first section and a second section. The first section of the small capacity memory retimes data samples for subcarrier phase errors without losing or repeating data, while the second section of the small capacity memory retimes data for horizontal frequency error without losing or repeating data in all reproducing modes except shuttle. Further, the second section of the small capacity memory in reverse and forward shuttle retimes the data for horizontal frequency and phase errors while equalizing the data rate through the time base corrector by selectively discarding or repeating horizontal lines based on line type. The large capacity memory in all reproducing modes except shuttle retimes data for timing errors of line and field phase while in shuttle the memory retimes for field phase only.
