Abstract: During recording, a multilingual indication is generated when at least two of the audio channels of a digital audio signal are associated with a common program, and the multilingual indication is combined with the digital audio signal. During reproduction, a display is activated when a multilingual indication indicates that at least two of the audio channels included in a digital audio signal are associated with a common program.

Abstract: A video tape recording and reproducing apparatus records and reproduces digital video signals representing both still pictures and moving pictures in the form of coded signals that have a recording format which includes a video signal recording area (VIDEO AREA) for recording video data and respective accompanying video information, and a subcode information area (SUBCODE AREA). The recording and reproducing apparatus generates signals for high speed cuing and reproduction of the still pictures and moving pictures and stores the signals in the accompanying video information and in the subcode area.

Abstract: 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.

Abstract: A digital signal recording and/or reproducing apparatus can maintain satisfactory continuity of a previously-recorded area and a postrecorded area by reducing the tracking displacement between the previously-recorded area and the postrecorded area. A signal from a playback amplifier (10) is supplied to a f1/f2 discriminating circuit (13), and a discriminated signal is supplied to a tracking information detector (14). A memory means (15) is controlled by a system controller (100). Tracking information from the detector (14) is supplied to the memory means (15) which independently memorizes tracking information signals of respective areas of a video signal, an audio signal, a subcode signal and an ITI signal. Tracking information signals of the respective areas memorized in the memory means (15) are selected by a selector means (16) formed of switches (161 to 164) and supplied to an averaging circuit (17). A tracking information signal averaged by the average circuit (17) is supplied to a servo circuit (8) which effects a tracking correction. For postrecording of a said area, tracking correction is performed using the tracking information for a predetermined area of said areas. A digital signal recording and/or reproducing method thereof also is provided.

Abstract: Magnetic recording apparatus are provided for recording signals on a magnetic tape (102). A recording head (41) records signals in successive tracks on the tape and a tape transport transports a magnetic tape past the recording head in a recording direction. In one embodiment, absolute track addresses are recorded in at least some of the tracks, the absolute track address of each track corresponding to a distance of the track from a start position (43) of the magnetic tape. Recording is initiated from a track having a predetermined absolute track address corresponding to a predetermined distance from the start position. In a further embodiment, the tape transport transports the tape initially by a distance (R) necessary to establish a stable running state, and thereafter transports the tape a further distance (S) while recording reproduction control signals so that during reproduction a stable running state may be achieved. Thereafter, information to be output is recorded.

Abstract: A method of dubbing compressed digital video signals (32) adopted for an apparatus (1-15) for efficient coding and subsequent recording/playback of video signals. In the method of dubbing compressed digital video signals, on a playback unit side (8-15), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of playback, the digital video signal is provided with a parity for transmission by a parity generating circuit (6) and is then transmitted to a recording unit side (1-7). On the other hand, on the recording unit side (1-7), after padding error data by an error processing circuit with respect to an error uncorrectable in error correction by an ECC circuit (10) of transmission, the digital video signal is provided with a parity for recording by a parity generator (6) and is then recorded in a recording medium.
