摘要： PURPOSE:To reduce the amount of data when the two systems of video signals of stereoscopic images with mutual correlation are compressed. CONSTITUTION:The video signal L for left eye is added on the video signal R for right eye by an adder 11(+), and the video signal R for right eye is subtracted from the video signal L for left eye by a subtractor 11(-). A sum signal (L+R) and a differential signal (L-R) are converted to the data of prediction, orthogonal transformation, and sub-band division, etc., by transformation parts 12(+), 12(-), respectively, and scalar quantization or vector quantization is applied to those data by quantization parts 13(+), 13(-), respectively, and Huffman-coding and arithmetic coding, etc., are applied to each quantized value by encoder parts 14(+), 14(-), respectively.

摘要： A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which a plurality of fields of video signals are recorded for each track turn on a spiral track comprises a reproducing transducer having a reproducing element for scanning over tracks on the rotary recording medium to reproduce recorded signals, and shifting device responsive to a signal applied thereto for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium, and a circuit for producing shifting a signal in order to shift the reproducing element by one track pitch towards the outer side on the rotary recording medium every time the reproducing element reaches one predetermined position on the rotary recording medium, and capable of producing a shifting signal for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium according to the slow-motion ratio and the direction of the slow-motion reproduction when the reproducing element reaches another predetermined position on the rotary recording medium. The shifting signal is supplied to the shifting device. The tracks are reproduced a plurality of times with respect to each track turn, to perform a slow-motion reproduction.

摘要： A periodical signal detection circuit is designed for use in an apparatus which reproduces an information signal and a periodical signal from a recording medium. A separation circuit separates the periodical signal from the reproduced signal. A reference pulse is generated at a repetition frequency which is the same as the frequency of the periodical signal. A first gate circuit responds to the periodical signal obtained from the separation circuit and to the reference pulse signal. A first counter produces an output by counting N of the reference pulses (N is an integer greater than or equal to 2). A second gate circuit passes the signal from the separation circuit according to the output of the first counter. An output circuit detects the signals in responsive to the reference pulse, and the output of either the first or the second gate circuit.

摘要： A reproducing apparatus comprises a reproducing circuit including a pickup reproducing element, for reproducing recorded signals from a rotary recording medium, an address signal reproducing circuit for reproducing a track shift address signal from the signals which are reproduced by the reproducing circuit, a detecting circuit for detecting whether the address signal is reproduced with a predetermined period, a memory for storing the value of the reproduced address signal or a flag which is related to the value of the reproduced address signal, when the detecting circuit detects that the address singal is reproduced with the predetermined period, and a circuit for generating a control signal which causes the pickup reproducing element to undergo a forced track shift at predetermined positions on the tracks so that the pickup reproducing element scans along a scanning locus which has the same periodicity as the scanning locus along which the pickup reproducing element had been scanning up to that point. The control signal is generated based on the value of the reproduced address signal when the detecting circuit detects that the address signal is reproduced with the predetermined period, and based on one or a plurality of values which are pre-stored in the memory when the detecting circuit detects that the address signal is not reproduced with the predetermined period.
