SYNCHRONIZING SIGNAL GENERATING CIRCUIT OF DIGITAL VIDEO SIGNAL PROCESS FOR DIGITAL AUDI TAPE SYSTEM

摘要

The generator for recording the synchronous signal on the digital andio tape before recording the digital video signal to identify the video tape includes a video data write enable signal generating circuit (10) generating enable signals for switch signal writing digitised video data stored in a RAM on the digital audio tape, output and initial reset signal of a clock input circuit (11), and synchronus signal writing the data after addressing the memory. With the output of the circuit (10), the synchronous data of 7FFF and 8 are provided from a synchronous signal generating circuit (4).
