ABSTRACT:
A method and apparatus is disclosed for recording and reproducing color television signals on a magnetic media such as magnetic tape, wherein the signals recorded on and reproduced from the magnetic media are in a digital domain. The analog color television signal is converted to digital signals in a manner whereby the horizontal blanking interval is compressed and digital synchronizing information is inserted in the compressed horizontal blanking interval for every line. Upon reproduction, the digital synchronizing information is extracted from the reproduced information and is provided to servo circuits for controlling the relative transport of the magnetic tape and operatively associated magnetic heads to effect synchronous reproduction of the recorded information relative to a reference signal.
