摘要:
There is provided a signal processing system for recording and reproducing a video signal and a digital audio signal with a rotary-head VTR and, more particularly, a memory control system which generates a block address and a memory write signal so that the sync signal for reproduced digital data is detected reliably and the digital data is stored in the memory circuit correctly.
摘要:
A signal processing system for absorbing asynchronism between a video signal and an audio signal which is caused when a PCM audio signal is to be recorded together with the video signal on a helical scan-type tape recorder. When the video signal and the audio signal are recorded on the same track, a recording band width of the audio signal should be narrow. A sample pattern is provided which assures rapid pull-in for both data clock reproduction and carrier reproduction, when the audio signal is modulated by QPSK or when Q-QPSK modulation is used.
