摘要： A digital audio data playback apparatus such as a digital audio disc player is configured such that a PCM encoder and associated circuits within the apparatus can be used both for playback of recording discs having only digital audio data recorded thereon and also for processing a digital audio signal output from a video disc player during playback of a video recording disc having digital audio data recorded thereon, superimposed upon frequency-modulated recorded audio and video data. This eliminates the need to provide a PCM encoder circuit within such a video recording disc player.

摘要： In a color video information reproduction system such as video disc player and video tape recorder, the color burst signal is inserted into each horizontal period even during the vertical blanking period of a video information signal when the video information signal is recorded in order to obtain correct time axis variation information of a reproduced signal. Upon reproduction of the recorded video information signal, the color burst signal is separated from the reproduced signal and phase difference between the separated color burst signal and a reference signal is detected. The time axis servo system is driven on the basis of the detected phase difference and a stable and improved reproduced picture can be obtained while preventing an adverse influence to the audio information.

摘要： A video disc player in which undesirable frequency variations in reproduced video and audio signals due to absence of the color burst signal during the vertical retrace time are eliminated. A first control unit actuates a tangential mirror driver unit in response to a phase difference produced by comparing a horizontal synchronizing signal from the reproduced video signal with a reference color subcarrier signal. The video signal is delayed by an electronically-controlled variable delay line the delay time of which is set on accordance with a phase difference between the color burst signal and a reference horizontal synchronizing signal.

摘要： A method for recording broad-band color video signals in which the broad-band 3-color signals are separated into narrow-band 3-color signals and a high-band monochrome signal having a higher frequency band. The high-band monochrome signal is divided into three bands and frequency-converted respectively. The frequency-converted three bands of the high-band monochrome signal are merged into the narrow-band 3-color signals, while maintaining the frequency interlace relationship, so that three composite color video signals are produced. The thus produced three composite color video signals are recorded on different regions of recording medium.

摘要： A disk player in which the audio signal can be reproduced during FAST and SLOW playing modes. The speed of the spindle motor is controlled in accordance with the phase and frequency difference between a reference synchronizing signal and a synchronizing signal derived from information read from the disk. The frequency of the reference synchronizing signal is made variable to vary the speed of the spindle and hence the speed of reproduction of the disk.

摘要： A reproducing apparatus and method for both CD and complex disks capable of displaying a still frame of video information during the reproduction of the audio portion of a complex disk. When reproduction of a disk is first started, it is detected whether the disk is a complex disk or a CD. In the former case, the pickup is immediately shifted to the region where both audio and video information are recorded and reproduction is begun. During the reproduction of this region, a frame of video data is extracted and saved in a memory for reproduction during the playing of the solely audio portion of the disk.

摘要： An optical video disk, an optical disk recorder, and a playback unit for an optical video disk in which a digital data signal is divided into blocks, each being formed of a fixed number of bits, and the length thereof after interleaving is made longer than one field of a television video signal but shorter than one frame thereof. As a result, at least one block is made to correspond to one frame or field of the video signal, and the end portion of the block after interleaving is recorded at a position close to a point corresponding to the vertical synchronizing signal of the video signal and at the same time recorded on a corresponding frame or field basis. Accordingly, digital data in the form of blocks may be made to correspond to specific frames or fields, whereby desired picture images or digital data can readily be retrieved and played back.

摘要： A video disc recording and reproducing system in which a program is stored on a video disc to eliminate the need for the user to manually input a control program. A program and control signal is recorded in place of at least a portion of one of two audio tracks on a video disc along with video signals. The video disc player of the system includes modulator circuits which demodulate the video and audio signals from the disc, a central processing unit connected to the output of the demodulator circuit for demodulating the audio signal for detecting the control signal and program recorded on the video disc, and a memory for storing the control signal and program. The central processing unit controls the memory for storing the program and control signal at predetermined locations corresponding to the state of the control signal.
