    Abstract: A recording and reproducing device provided with at least a pair of rotary heads having different azimuths, running control means which controls the running of a magnetic tape, and recording timing control means which controls the recording by the rotary heads so that the recording can be performed in a first period when digital data having a first data rate are inputted, whereby the digital data can be recorded on the magnetic tape at the recording timing of the recording timing control means. In addition, the recording and reproducing device is also provided with a memory means which temporarily stores digital data supplied from the outside, reading means which reads out the digital data stored in the memory means, and signal processing means which performs a prescribed process of the digital data read out from the memory means. When digital data having a second data rate which is different from the first data rate are inputted, the recording timing control means and reading-out means perform processes at a speed based on the ratio between the two data rates and, at the same time, the running control means controls the running speed of the magnetic tape based on the data rate ratio.

    Abstract: The video tape recorder wherein a video signal is converted into a digital signal to be segment-recorded to make possible smooth continuation of consecutive taking in picture recording. A predetermined identificaion data (VIDEO ID, TRACK ID) is added when segment-recording a video signal. At the time of starting recording, the magnetic tape (T) is rewound and switching to reproducing mode is made and then, on the basis of the identification data, switching from the reproducing mode to recording mode is made at a break (6) between units (4, 2; 8, 10, 12) of signal processing.

    Abstract: Processing (such as recording and/or reproducing) apparatus is capable of processing first and second digital signals with the same processing device, even when the two digital signals have differing first and second data configurations, the first data configuration containing a greater amount of data than the second data configuration. Predetermined data is added (23) to the second digital signal so as to convert the second data configuration to the first data configuration. An error processor (4A), such as an error detection/correction generator or an error corrector, and capable of processing the first data configuration, selectively (21) receives either the first digital signal or the converted second digital signal, so as to carry out the same error processing operation on either one of the digital signals. The first digital signal may be a video signal, and the second digital signal may be an audio signal.

    Abstract: Methods and apparatus are provided for recording and reproducing digital information signals including image and audio portions in successive tracks on a magnetic tape. An ID signal is produced (112) for one of an image portion and an audio portion of a corresponding digital information signal to be recorded. The ID signal indicates whether the portion is to be after-recorded in a respective track. The ID signal is combined (14) with the portion to form a recording signal. Previously recorded digital information signals are reproduced (13A, 13B, 21A, 21B, 22, 23) from the track and an ID signal thereof is obtained. The recording of the portion in the track is controlled (51, 52, 53, 54, 55) based on the reproduced ID signal.

    Abstract: A magnetic recording and/or reproducing device uses a viterbi decoding circuit (40, 41) wherein, when data falls within a predetermined range, the level of the reproduced signal is corrected in a manner which reduces bit error caused by noise in the reproduced signal. Alternatively, the value of a previous video signal value is corrected in accordance with the amount of change in an instant signal value.

    Abstract: In an apparatus for detecting input digital data, for example as derived by analog-to-digital conversion (6) of a reproduced binary signal in analog form, the input digital data is distributed into at least two channels, a processing circuit (21,22) in each channel processes the respective digital data in accordance with a predetermined formula (1 + D), a Viterbi decoder (23,24) in each channel decodes an output of the respective processing circuit (21,22) in accordance with the Viterbi algorithm, and the outputs of the decoders (23,24) are combined (25) to provide a single sequence of digital data.
