ABSTRACT:
A programmable time code generator utilizes a synchronous parallel-to-serial data converter for conversion of time code in parallel form into serial form. The resulting longitudinal time code is suitable for recording on magnetic tape in synchronism with an information signal. The time code generator can be readily adapted for various video recording formats, such as NTSC, PAL, PAL-M, SECAM, etc., as well as for synchronous time code generation in other types of recording. In addition, the frequency of the generated longitudinal time code can be changed in a simple manner to be adapted for recording at various tape speeds which are different from the normal playback speed.
