    摘要: A recording apparatus for recording digital data comprised of a plurality of recording blocks on a recording medium includes a grouping circuit which makes a group of the digital data according to a predetermined time-based interval, A sequence number generator divides the group into "N" sequences. "N" is an integer. A data block generator divides the input data in each sequence into a plurality of data blocks. A sequence number generator generates a sequence number for each data blocks associated with each recording blocks, An ID block generator generates an ID information of each data block based on the sequence number. A recording block generator generates the recording block based on the ID information and the data block.

    摘要: In order to reproduce highly important information easily and at high speed, such information is composed into data of fixed length and is assigned from the beginning of a block. Without increasing the recording rate, in order to record a signal so that the highly important information may be reproduced securely, a dummy sync block is inserted immediately before a data sync block which contains the highly important information for defining or explaining the content of the signal to be recorded. To maintain the error correction capability in a normal play mode, moreover, the sync block composition which is the same as in the signal to be recorded is used for the highly important information. In particular, as for such information, by assigning the information in plural sync blocks, reproduction is securely realized also in the case of a trick play mode.

    摘要: Two, HD and SD, signals are arranged so as to be identical to each other in the recorded form on a recording medium. Reciver circuits, encoder circuits, and a recording circuit for SD signals are provided. Also, a receiver circuit, an encoder circuit, and a recording circuit for HD signals are provided. In addition, a circuit is provided for identifying whether the input signal is an SD or HD signal. Accordingly, both the HD and SD signals can be recorded using one single digital VCR while no further hardware is involved. Simultaneous recording of a plurality of SD signals and high-speed dubbing of SD signals may be executed using an HD signal processing circuit.

    摘要: A video and voice signal processing apparatus is provided. The apparatus includes a signal receiving circuit for receiving an input signal containing a plurality of frames, each frame having an encoded voice signal block and an encoded video signal block. The signal receiving circuit separates the encoded voice signal block from the encoded video signal block in each frame. A voice signal processor converts the encoded voice signal block into a voice signal. Also included is a video extracting circuit which decimates a plurality of encoded video signal blocks and extracts one of the encoded video signal blocks as a representative video signal. A video signal processor converts the representative video signal into a video signal.

    摘要: An apparatus serving as a digital videocassette recorder (VCR) for recording analog video and audio signals as digital signals. The apparatus serves also as a digital data storage drive. The digital VCR and the storage drive share common circuitry and a common magnetic recording medium. This reduces the cost and enhances the efficiency at which tracks are used. The apparatus has a large storage capacity. The apparatus divides input digital data into two parts and performs error correction encoding for each of these two data parts to form sync blocks. These sync blocks are recorded in an audio signal recording area and a video signal recording area, respectively, on the recording medium. Error correction codes used during reading of digital data are the same as those used during recording of video and audio signals. The same track structure and the same sync block structure are used for these two modes of operation.
