摘要： It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A tape travel speed of an archive VTR 4 is changed in response to the picture compression rate. Thus, an amount of a tape travel is optionally set depending upon a level of the picture quality. Therefore, it is possible to optionally select a tape storage space in response to the level of the picture quality.

摘要： An optical transmitter converts serial hi-vision digital signals sent from a transmitting side peripheral device over a coaxial cable into serial digital optical signals to transmit the resulting signals over an optical fiber. An optical receiver receives the serial digital optical signals sent from the optical transmitter over the optical fiber to convert the signals into serial hi-vision digital signals to transmit the converted signals over a receiving side coaxial cable to a receiving side peripheral device. This enables transmission of digital signals to the receiving side peripheral device with suppressed signal deterioration without requiring a complex structure.

摘要： A servo circuit is provided for use with a reproducing apparatus wherein an information signal is reproduced from an elongated slant track formed on a tape which is wrapped on the periphery of a guide drum having a rotary head. The servo circuit includes a circuit for detecting an intermediate point of the length of the slant track and generating a timing signal at the detection of the intermediate point and a circuit for comparing the timing signal with a reference pulse to generate a control signal. A relative position of the slant track to the rotary head is controlled in accordance with the control signal.
