摘要： The invention relates to a system for recording and/or reproducing information, comprising a magnetic tape and an apparatus comprising a magnetic head unit which is movable on a transverse direction by means of an actuator. By means of a write head, the magnetic tape has been provided with a pattern of servotracks ST101-ST127 which extend in a longitudinal direction. The odd-numbered servotracks contain a first servosignal and the even-numbered servotracks contain a second servosignal which is phase opposition to the first servosignal. The servotracks ST103-ST113 and ST116-ST126 have a typical width W1 and form a group of two bands of N1 servotracks which are separated by a band of N2 servotracks ST114, ST115 having a typical width W2. The magnetic tape is adapted to cooperate with an apparatus comprising eight magnetic heads. The actuator is controlled in response to the servosignals read by the heads.

摘要： Methods and apparatus for converting digital signals having a variable data rate to fixed data rate signals suitable for recording on a tape by a digital video tape recorder are disclosed. The methods include buffering of the received variable rate data, measuring the data rate of the received data for a fixed period of time and processing the buffered data to converted it into a fixed rate data stream. This processes is repeated for each of the fixed periods of time. Methods for increasing the recording time of a digital video tape recorder ("VTR") and for supporting multiple normal play modes of digital VTR operation, e.g., recording modes for recording SDTV and HDTV are also disclosed. To generate fixed data rate signals from variable data rate signals one or more of data padding and/or data reduction techniques are used. The same data reduction techniques used to generate the fixed rate data stream are used, in accordance with various embodiment of the invention, to reduce the amount of data required to represent a video frame.

摘要： Method for increasing the recording time of a digital video tape recorder ("VTR") and for supporting multiple normal play modes of digital VTR operation, e.g., a standard play mode of operation and one or more long play modes of operation. To achieve long play mode operation data reduction is performed on a received full rate video data stream to generate a reduced rate video data stream. Data reduction is performed using data prioritization and selection, requantization of full rate data stream, and/or by selecting data to be included in the reduced rate data stream as a function of what portion of a video frame the data represents. The reduced rate data stream is generated to be compliant with the data format of the full rate data stream. During long play mode recording operation the data in the reduced rate data stream is recorded on a tape at the same tape data density as used during standard mode VTR operation. In accordance with each of the recording methods of the present invention the rotational rate of the digital VTRs headwheel is the same for both standard and long play modes of VTR operation. In addition, the present invention is directed to several methods of reading data from a tape at a reduced data rate.

摘要： A signal recording apparatus is arranged to record main information in a first area provided in each of a multiplicity of parallel tracks formed on a tape-shaped recording medium, and an index signal in a second area of each of a predetermined number of continuous tracks, the second area being provided separately from the first area within each of the multiplicity of parallel tracks. The apparatus records, as the index signal, first index information in a first section within the second area of each of the predetermined number of continuous tracks, with either one of binary data being repeated continuously during a period corresponding to the first section, and second index information in a second section within the second area of each of the predetermined number of continuous tracks, the second index information including track data indicative of relation to a specific track among the predetermined number of continuous tracks. In the above-described arrangement, it is possible to increase the speed of search for a specific track by using the first index information and to improve the accuracy of search for the specific track by using the second index information.

摘要： An apparatus and a method for variable speed searching of recorded pictures on a storage medium is disclosed. The apparatus comprises a recording-playback device which records pictures and an information value signal, and plays back the recorded pictures. A speed controller responsive to the information value signal adjusts the speed of the recording-playback device during a fast-scan search (i.e., fast-forward or fast-backward search). The fast-scan search speed is adjusted so that the recorded pictures with high information values are played back at a slower fast-scan speed and the recorded pictures with low information values are played back at a faster fast-scan speed. The information value signal is generated during recording or during playback. The information value signal has a low value when a correlation between temporally successive recorded pictures is high, and a high value when the correlation is low, the correlation depends upon temporal redundancy between the successive video pictures. In short, an apparatus and a method for variable speed searching of recorded pictures is provided in which the fast-scan speed is automatically adjusted to allow for viewing of static and dynamic scenes at a proper speed during a fast-scan search.

摘要： In a method for synchronizing recording and reproducing devices including a master device and a slave device, during a recording mode and in a state where reference clock of the slave device is synchronized with reference clock of the master device, position information which is synchronized with the reference clock of the master device is recorded commonly in both the master and slave devices and information to be recorded is simultaneously recorded in both the master and slave devices. During a playback mode, the master device and the slave device reproduce the position information respectively at their own reference clocks and cause internal counters provided in the respective devices to perform counting at their own reference clocks and to be reset at a predetermined period of the position information reproduced in the respective devices. The slave device compares a reproduced value of the position information and a count value of the internal counter provided by the master device with a reproduced value of the position information and a count of the internal counter of the slave device and thereby causes the reference clock frequency of the slave device to change so that differences between the values of the master device and those of the slave device become predetermined values.

摘要： A method of display control is disclosed for an audio tape deck having a display unit employing an array of light-emitting segments, whereby both data relating to playback audio signals and tape transport data can be selectively displayed in the same display region. Any change in operating status from a normal play mode of operation during display of audio playback signal data is sensed, causing changeover to display of tape transport data, and after a fixed time has elapsed following return to the play mode the display of audio playback signal data is restored.

摘要： A digital audio disc (DAD) reproducing apparatus comprises pulse width detection and pulse width-to-voltage conversion means for detecting a signal having a predetermined pulse width such as a maximum or minimum pulse width of code modulated digital data signals reproduced by a pickup and converting the detected signal to a voltage proportional to the pulse width, and pulse width error detection means for detecting an error between the converted voltage and a reference voltage corresponding to a reference pulse width. Since the pulse width of the digital data signal changes with a clock rate, the error from the reference voltage represents an error in the clock rate.
