Abstract: A digital video tape recorder ("VTR") that selects data useful for generating images during trick playback operation and records the data in trick play tape segments arranged on a tape to form fast scan tracks and multi-speed playback tracks. Each fast scan track comprises trick play tape segments located on a diagonal, relative to the length of the tape, of the same angle as the angle at which the heads of a VTR are expected to pass over the tape during trick-play operation at a specific speed and direction of operation. Each multi-speed playback track comprises a plurality of trick play tape segments arranged parallel to the length of the tape. Data which is used for at least one mode of trick play operation is recorded in each trick play tape segment. Each fast scan track and multi-speed track crosses multiple normal play tracks. During playback at a wide variety of speeds and directions, the heads pass over enough trick play segments of the multi-speed playback track to generate recognizable images during trick play operation. During specific speeds of playback operation supported by the use of fast scan tracks, data read from the fast scan tracks provide images of better quality than data that can be read from the multi-speed track. Data is recorded in each trick play segment in a manner that optimizes the amount of data that can be routinely recovered during trick playback operation despite tracking errors.

Abstract: A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

Abstract: A recording method is provided for a video tape recording apparatus having modes for recording PCM audio signals in a plurality of transmission rates. Index codes (104) for a video signal, which enable a search reproduction and so on, are recorded on a video tape in a constant transmission rate irrespective of the transmission rate of a PCM audio signal to be recorded. Further, an amble pattern (501) at the same frequency as the transmission rate of the PCM audio signal is recorded immediately behind the PCM signal recording area (102). A reproducing apparatus may be provided only with an index detecting circuit (603) corresponding to the constant transmission rate.
