摘要： A digital audio disc (DAD) reproducing apparatus comprises pulse width detection and pulse width-to-voltage conversion means for detecting a signal having a predetermined pulse width such as a maximum or minimum pulse width of code modulated digital data signals reproduced by a pickup and converting the detected signal to a voltage proportional to the pulse width, and pulse width error detection means for detecting an error between the converted voltage and a reference voltage corresponding to a reference pulse width. Since the pulse width of the digital data signal changes with a clock rate, the error from the reference voltage represents an error in the clock rate.

摘要： A circuit for reproducing and demodulating a modulated digital signal which is modulated in a predetermined modulation system such as MFM, EFM and so on. A phase of a clock having a frequency multiplied by an integral number of a bit frequency of the modulated digital signal, is restricted or controlled by a signal showing that a predetermined pattern of the modulated digital signal occurred. The modulated digital signal is demodulated by the thus restricted clock to produce digital informations "0" and "1". A main requirement for detecting the predetermined pattern of the modulated digital signal, is that a reproduced modulated digital signal is reliable. In order to compensate for the drop-out of the modulated digital signal, the demodulation circuit is provided with a modulated digital signal reproducing circuit for complementing a predetermined signal pattern when the drop-out occurred.

摘要： A processing system and a recording/reproducing system for a digital signal including a digital video signal and a digital audio signal are disclosed. Upon transmission, the digital signal is transmitted after time-base compression and modulation. The transmitted signal is received and demodulated. In the case where the signal is to be transmitted to a plurality of recording/reproducing systems, address signals designating ones of the plural recording/reproducing systems and a control signal for controlling the start/stop of recording are transmitted. The recording by the recording/reproducing system is controlled so that it is made with the same format in either normal-speed or high-speed mode or in either normal or multiple recording mode.
