ABSTRACT:
A digital data manipulation system for compensating for drop outs on a video recording medium. Data received by an assembler is assigned to a predetermined non-standard format prior to recording. Addition of synchronizing information via process amplifier allows the digital data to be recorded on an analog video tape recorder as lines of video information. A checksum generator and parity bit generator are provided to effect two dimensional coding indicative of assigned data content both prior to recording and following playback. By detecting any differences between the coding information this identifies drop out errors to allow compensation therefor.
