摘要： A digital video recording system for digitizing analog video signals and recording the digital signals on video tape and for reading digital video signals from video tape and producing an analog video signal. The recording system comprises an A/D converter, a data compressor for compressing digital video signals at a data rate of 1/N (N: an integer greater than 1), a selector mechanism for selecting between the compressed digital video signal and a non-compressed digital video signal, and a control mechanism for controlling the system such that recording data for one field, which is normally recorded in M tracks (M: an integer greater than N) in ordinary recording mode, is recorded in about M/N tracks in a long recording mode.

摘要： A digital video tape recorder has interpolation and crossfading circuits and records audio and video signals in independent frames, the audio frames being offset with respect to the video frames. For a four-channel audio signal, the even and odd samples are recorded near different edges of the tape, enabling burst errors near one edge to be recovered efficiently by interpolating the audio signal from the other edge. When audio dubbing is performed, the first and last dubbed frames contain the even samples of the new signal and the odd samples of the old signal, or vice versa, and audio-dubbing flags are recorded in the these frames. When these frames are played back, the old and new signals are regenerated by interpolation and crossfaded to create a smooth transition between them. The same apparatus can also be used to record a two-channel signal, by recording each sample twice.

摘要： A variable length coding method designed to assign a different number of coding bits in accordance with the information content a sample holds when an analog signal such as a television signal or the like is converted to a digital signal. An assigning method of coding bits used to a luminance signal is different from that used to a chrominance signal. A variable length coding method is further capable of selecting an optimum assigning method in accordance with contents of an original signal from a plurality of determined assigning methods of coding bits. The data related to the plurality of assigning methods of coding bits is recorded on a medium after it is added to a coded digital signal.
