摘要： A video recording apparatus provides a slow motion effect or a quick motion effect by digitally converting the frame-rate instead of by changing the playback speed of the film, and using few recording media without requiring any special device at playing. A picture encoding part encodes only valid frames by changing a rate-controlling method so that a predetermined playing frame-rate is obtained at a standard data-rate at playing. And a TS multiplexing part multiplexes by converting a frequency of a standard STC clock by only a ratio of valid frame-rate and playing frame-rate, and generating values for PCR, PTS, and DTS.

摘要： In transmission or recording of a digital signal by means of digital amplitude and phase modulation, particularly recording into and reproducing the same from the a magnetic recording medium, a digital amplitude/phase modulated signal to be demodulated is commonly affected by the non-linear amplitude characteristics and the effects of unwanted jitter and envelope variation. As the result, the error rate of decoded data will be increased. For compensation, the Viterbi decoding technique is employed with the use of a weighted distance value calculated by multiplying an Euclidean distance between the signal point of a reproduction signal and the datum point of each code by a positive weighting factor which is determined smaller when the code datum point is located further from the origin point of a coordinate system. Accordingly, the weighted distance of each reproduction signal point from its corresponding datum point can approximately be uniform thus ensuring less error decoding in general.

摘要： The present invention provides a recording apparatus that generates a transport stream so that a boundary between recording units (aligned units) and a file division point (i.e., a boundary between GOPs) always coincide with each other without obtaining information on the file size or the like. When generating a transport stream by time-division multiplexing transport packets, n or more transport packets (e.g., null packets N) other than a video packet are inserted between a video packet group generated from a single encoding unit (GOP) and a video packet group subsequent to the video packet group. When d indicates the data length of the transport packet, h indicates the data length of a fixed-length header added to each of the transport packets before being recorded on a data recording medium, and L indicates a recording unit length to the data recording medium, L≦(n+1)×(d+h) is satisfied.

摘要： A digital signal magnetic recording/reproducing apparatus converts a digital signal into multi-value digital signals and performs recording/reproducing of a multi-value quadrature amplitude-modulated signal. By using the multi-value quadrature amplitude modulation, it is possible to remove the DC component in the recording signal and improve the utilization efficiency of the recording frequency band. Further, using a system to memorize the frequency characteristic of the magnetic recording/reproducing unit and effect Viterbi decoding regarding the intersymbol interference caused by the frequency as a convolutional coding, it is possible to detect the level without necessitating frequency equalization. Accordingly, there arises no deterioration of the S/N ratio by frequency equalization. Furthermore, by providing an encoder for error control coding by increasing the number of multi-values and a corresponding decoder, the error rate can be improved against the deterioration of the S/N ratio. Further, by bias recording the multi-value quadrature amplitude modulated signal, non-linearity of the electromagnetic conversion system is relaxed, and deterioration of the S/N ratio by distortion is improved.

摘要： A digital signal magnetic recording/reproducing apparatus converts a digital signal into a multi-value digital signal, followed by recording/reproducing the quadrature biphase modulated multi-value quadrature amplitude modulated signal. By using a multi-value quadrature amplitude modulation, a direct current component in the recorded signal can be eliminated, and the utilization efficiency of the recording frequency band of the digital signal magnetic recording/reproducing apparatus can be improved. Also, with respect to the amplitude non-linear characteristic which occurs in the magnetic recording/reproducing process, by providing a compensating circuit during the mapping before recording or after reproducing and demodulating, the deterioration of the S/N ratio of the reproduced and demodulated signal can be reduced to decrease the errors in the decoded data. Furthermore by bias-recording the multi-value quadrature amplitude modulation signal, the non-linearity of the electromagnetic conversion system is alleviated to decrease the deterioration of the S/N ratio due to distortion, thereby making the application of the modulation scheme more reliable.
