摘要： A first reproduction signal is reproduced by use of a first pair of magnetic heads having first and second azimuth angles and arranged around a rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A second reproduction signal is reproduced by use of a second pair of magnetic heads having first and second azimuth angles and arranged around the rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A video signal is reproduced based on the first and second reproduction signals. The magnetic tape travel speed is set to a value (2n + 1 ± m/M) times higher than that in recording, where n is an integer of 0 or more; m and M are a natural number, respectively; T ≧ 12/(P + Q) (T: an integer) when m/M = 2k/T; and P > O, Q > O.

摘要： A real-time disk system (10) stores and plays back D1 digital 10-bit 4:2:2 component video and audio signals from magnetic storage disks (12). The system (10) has a main channel subsystem (14) with an associated smooth motion option (16) and a second or key channel option subsystem (18) with an associated smooth motion option (20). Serial and parallel D1 digital video inputs (30 and 32) and outputs (34 and 36) are connected to each of the channels (14 and 18) and to control subsystem (22). In the main channel (14), the serial and parallel D1 input (30) is connected through an input board (60) to a video processing board (62). The video board (62) is connected by a bidirectional, 11 x 2 wide bus (64) to disk arrays (66 and 68). Digital video signal information is stored and retrieved in parallel to and from the disk arrays (66 and 68) without requiring any serial to parallel or parallel to serial conversion. Smooth motion option (20) processes a group of video fields by creating a plurality of additional fields between two original fields in the group of video fields by a combination of motion adaptive interpolation and frame repetition.

摘要： A digital recording/reproducing apparatus having an external input digital interface is disclosed. A changeover switch is controlled by a changeover control circuit for selecting horizontal synchronizing signals generated by a horizontal synchronizing generator for an external input mode and for selecting horizontal synchronizing signals derived from reproduced video signals reproduced from a recording medium for a playback mode. Standard color sub-carrier signals may be generated by a color sub-carrier signal generator based on the horizontal synchronizing signals as selected by the changeover switch. Even when the digital video signals supplied from outside for the external mode include non-standard horizontal synchronizing signals, standard composite video signals may be generated by an encoder by employing the color sub-carrier signals from the color sub-carrier signal generator.

摘要： In a video recorder (1) for the recording and reproduction of picture signals in standard-play modes and long-play modes a reconverted picture colour signal supplied by a frequency-conversion stage (70) is passed through a delay device (84) having a delay of one line period in order to compensate for reproduction-dependent time errors during multi-speed reproduction of a long-play recording. In such a video recorder (1) a rectangular detection signal of half the line frequency is supplied to an output (76) of a phase detection stage (73) which detects the phase of the burst signal in the reconverted picture colour signal, which detection signal is applied, via a connection (91), to a modulator (36) for the modulation of non-modulated character signals as a control signal (S2) for the modulator (36), which generates modulated character signals suitable for insertion into the reproduced picture signals. The connection (91) includes a switching device (93) which enables a further delay device (94) having a delay of one line period to be included in the connection (91) in the case of multi-speed reproduction of a long-play recording by the video recorder (1), as a result of which the control signal (S2) is delayed by the same time as the picture colour signal during such a reproduction mode, which ensures that the picture colour signal and the character colour signal always remain locked to each other in the same way in all the modes of operation.

摘要： Image signal demodulation apparatus for demodulating an FM image signal having a carrier, an upper sideband and first and second lower sidebands, of which a modulating signal frequency is comparably close to a frequency of the carrier. The apparatus comprises an equalizer (3) for equalizing a group delay characteristics of the FM image signal at around the carrier frequency, a moire reduction circuit (7) for delaying, with respect to the carrier, respective aliasing components of the first and second lower sidebands by predetermined amounts respectively in response to the output of the equalizer, a limiter (4) for removing amplitude variations of the output of the moire reduction circuit and restoring the upper sideband, a demodulator (5) for demodulating the output of the limiter. The output of the demodulator contains a baseband component having a maximum frequency, and a lowpass filter (6) for passing only the baseband component lower than the maximum frequency. The demodulator together with the moire reduction circuit causes to perform as such that a first moire component generated due to an aliasing caused upon modulation of the FM image signal, becomes opposite in phase relationship to a second moire component generated upon demodulation of the FM image signal, so that the first and second moire components are cancelled out each other.
