摘要:
A digital video signal is recorded in a first number of tracks in a standard play (SP) mode and in a second number of tracks in a long play (LP) mode, wherein each frame of the digital video signal is recorded in first and second sets of tracks in the SP mode and in only a first set of tracks in the LP mode, each track having subcode data recorded therein for locating frames during a high speed search of the record medium. The digital video signal is compressed prior to recording in both the SP and LP modes, with the compression ratio being greater in the LP mode. When the digital video signal is recorded in the SP mode, the subcode data is of a first type for recording in the first set of tracks and is of a second type for recording in the second set of tracks; whereas when the digital video signal is recorded in the LP mode, only one type of subcode data is recorded. Hence, in the SP mode, a frame of compressed digital video signals includes subcode data of both types; and in the LP mode, a frame of compressed digital video signals contains subcode data of only one type.

The invention provides an input device (1) which includes a gripping part (2), a pointing part, and at least one depressible part (6) furnished in such a manner that while holding the gripping part by hand, a user may manipulate the pointing and depressible parts with fingertips to perform the same kinds of operations as those of a mouse. The input device may include a rotating and/or a pivoting part (7) and at least one operating element which provide a still wider variety of functions when operated.

There is realized a cassette (41a,41b) with a memory (MIC) in which the writing time is short, it can be accessed in a short time, and there is no need to provide an apparatus side of a main body with an additional memory. The memory (MIC) comprises an EEPROM (SPACE 0) to store fundamental data such as table of contents (TOC) information or the like, and a large capacity memory (SPACE 1), for example, flash memory, to store data.

A digital video tape recorder (200) records a teletext signal together with a digital video signal on a magnetic tape (40). The teletext signal is extracted from a broadcast video signal (BS) and recorded in the form of binary data in auxiliary data areas of a video signal recording region in each recording track on the magnetic tape.

A PCM (pulse code modulated) audio signal recording and/or reproducing apparatus is disclosed, in which a scanning track area formed by one scanning of a rotary head (1, HA, HB) on a tape (2) is separated into a plurality of track areas in its longitudinal direction to thereby form multi-channel segment track areas and the PCM audio signal (SL, SR) is recorded on and/or reproduced from each of segment track areas of each channel on the tape (2). According to this apparatus, when a plurality of programs are sequentially recorded in a timer scheduled event recording mode, it becomes possible to select (30) a recording mode (S) (series recording mode) in which the recording is carried out only on the segment track area of one channel and a mode (P) (parallel recording mode) in which the recording is sequentially carried out on segment track areas of different channels.
摘要:
In a cassette (41a;41b) with a memory (MIC) in which video data and audio data are digitally recorded: a plurality of additional information items are made to correspond to one predetermined video image; and a storing order of events is properly set and data processes in the memory in the case of adding or deleting character information are easily executed. Number information indicative of the number of text events corresponding to a program event is recorded in the program event. The memory (MIC) has: a main area in which tape information and the like are stored; and an optional area in which table of contents (TOC) information, timer recording information, character information, and the like are stored. In the case where character information regarding the events of the optional area exists, the character information is stored at the last position of the optional area.
