摘要： A frequency-multiplexed video signal is generated in which a color-under signal and a second under signal are linearly combined with at least partially overlapping frequency spectra to form a composite under signal for an FM luma signal. The frequency-multiplexed video signal is suited for recording on magnetic tape using helical scanning methods and for being played back from the magnetic tape using helical scanning methods. The second under signal is generated in such way that line-comb filtering can be used during playback to separate color-under signal and second under signal each from the composite signal despite their frequency spectra being at least partially overlapping in the composite signal.

摘要： An apparatus for synchronously reproducing compressed and multiplexed data for multi-angle reproduction. The apparatus for synchronously reproducing multi-angle data includes a plurality of reproducers to receive a data stream in which multi-angle data is multiplexed for multi-angle reproduction, to separate, decode and reproduce data corresponding to a predetermined angle from the received data stream and to generate a reproduction ready notice signal indicating that data is ready for reproduction. One of the plurality of reproducers synchronizes data reproduction of the plurality of reproducers based on the reproduction ready notice signals generated by the other reproducers. Thus, images involving various angles at an instant can be provided to a user.

摘要： A video recording/playback system includes in its recording electronics time-base correctors both for luma signal and for color-under signal, the time-base corrector for luma signal being used to facilitate comb filtering and the time-base corrector for chroma signal being used to maintain luma/chroma tracking during recording. The video recording/playback system includes in its playback electronics time-base correctors both for played-back luma signal and for played-back color-under signal, the time-base corrector for played-back luma signal being used to facilitate comb filtering and the time-base corrector for played-back chroma signal being used to maintain luma/chroma tracking during playback. With appropriate switching, the same pair of time-base correctors can be used in both the recording and the playback electronics of a video recording/playback system. A detector in the recording electronics determines when there is substantial time-base error in the video signal received for recording and conditions the comb filtering of the luma signal during recording to be carried out in just the spatial domain and not in the frame-to-frame time domain. The recording electronics includes circuitry for signaling the playback electronics, via a recorded signal, that the comb filtering of the luma signal during recording was carried out in just the spatial domain and not in the frame-to-frame time domain. The playback electronics responds to such signaling to adapt the comb filtering of the played-back luma signal to suit.

摘要： Apparatus is disclosed for processing the chroma and luminance signals reproduced from a magnetic recording medium. The chroma signal in passing through a separate path from the luminance signal may suffer a phase displacement relative to the phase of the reference luminance signal. Means are provided for connection between the chroma channel and the luminance channel to generate an error signal representing the phase displacement of the chroma signal relative to the reference luminance signal. Additional means are provided to use this phase error signal to restore the phase of the chroma signal to its original phase relative to the reference luminance signal, whereby to insure the accuracy with which the signals modulating the chroma carrier can be demodulated.
