摘要： A video tape recorder/player capable of selectively recording a wide-band video signal including information for forming a picture of an aspect ratio a.sub.1, and a normal video signal for forming a picture of an aspect ratio a.sub.2. The video tape recorder/player comprises video signal discriminating means for discriminating between the reproduced wide video signal and the reproduced normal video signal reproduced from a magnetic recording medium, and time expansion means for expanding the time base of the reproduced video signal by a factor approximately equal to the ratio a.sub.1 /a.sub.2. Either the reproduced video signal or the output signal of the time expansion means obtained by expanding the time base of the reproduced signal by the time expansion means can be selected as an output signal when the video signal discriminating means detects the wide video signal.

摘要： An audio signal recording/reproducing system is used in a time-lapse video tape recording device for time-lapse recording a video signal on a magnetic tape at predetermined time intervals. The audio signal recording/reproducing system comprises a memory which stores an audio signal and time-compresses the stored audio signal to output it as the time-compressed audio signal at one field period, and a magnetic head for recording the one-field period audio signal on the magnetic tape. Each of the audio signal recording tracks recorded on the magnetic tape is arranged between two adjacent video signal recording tracks. The audio signal recorded on the magnetic tape is read out by the magnetic head and stored in the memory again. The audio signal stored in the memory is expanded in its time-base to be reproduced as continuous sound.

摘要： A relay control circuit is disclosed in which a timer circuit is actuated by a reference clock pulse in synchronism with an AC voltage supplied by a commercial power supply. An output signal of the timer circuit causes current to flow in the coil of the relay thereby to close the contact of a relay. The invention further comprises a polarity-reversing device for reversing the polarity in accordance with the variations in the output signal of the timer circuit. The reference clock pulse is applied to the timer circuit through the polarity-reversing device.

摘要： In a magnetic video recording/reproducing apparatus having a recording circuit for recording two kinds of video signals for different aspect ratios a.sub.1 and a.sub.2, where a.sub.1 >a.sub.2, a reproduced signal for aspect ratio a.sub.1 is subjected to a time-axis processing and then delivered to a monitor television having the aspect ratio a.sub.2 in order to avoid a picture on the monitor television from being so distorted as to be elongated vertically. During the time-axis processing, a Y/C interleave set-up processing and a time-axis variation correcting processing are also carried out as necessary. A reproduced signal for aspect ratio a.sub.2 is subjected to a time-axis processing and then delivered to a monitor television having the aspect ratio a.sub.1 in order to avoid a picture on the monitor television from being so distorted as to be elongated horizontally.

摘要： A method and apparatus for reproducing information at variable speeds from a magnetic tape by correcting a deviation between at least one video track of the magnetic tape and a rotating head during a tape stop state of an intermittent drive for a noiseless slow-still picture in a video tape recorder using pilot signals. A series of pulses produced by a frequency generator of a capstan for feeding the tape is counted during the tape feeding state of an intermittent drive in order to detect a timing of the stopping of the tape feeding. As the count number equals a set value corresponding to a regular amount of feeding of the tape during the intermittent drive, the tape feeding is controlled to stop. A tracking error signal is produced from the pilot signals reproduced from the tape by the rotating head within the tape stop state of the intermittent drive and the set value for the next tape feeding of the intermittent drive is adjusted in response to the tracking error signal.
