Abstract

A recording and reproducing apparatus for recording and reproducing hybrid data, including at least one of video data, audio data and additional data, onto a recording medium is provided. The recording and reproducing apparatus includes: a bus for transmitting data therethrough; an interface for receiving the video data and the audio data and outputting these data to the bus; a text unit for generating text data and outputting the text data to the bus; a processor for receiving the video data, the audio data and the text data via the bus, generating the hybrid data from the video data, the audio data and the text data and outputting the generated hybrid data to the bus; a recording unit for receiving the hybrid data via the bus and recording the hybrid data onto the recording medium; a reproducing unit for reproducing the hybrid data recorded on the recording medium; and an output unit for displaying the hybrid data reproduced by the reproducing unit.

Claims

1. A recording and reproducing apparatus for recording and reproducing hybrid data, including at least one of video data, audio data and additional data, onto a recording medium, comprising:

a tape recording/reproducing unit for recording and reproducing the hybrid data by using a tape medium as the recording medium;

a disk recording/reproducing unit for recording and reproducing the hybrid data by using a disk medium as the recording medium;

a recording rate conversion unit operatively configured with the disk recording/rerroducing unit to record input hybrid data at a rate different from a normal recording rate at which the tare recording/reproducing unit concurrently records the input hybrid data;

a reproducing rate conversion unit operatively configured with the disk recordinq/reproducing unit to reproduce the recorded input hybrid data at a rate different from a normal reproducing rate at which the tape recording/reproducing unit would normally reproduce the recorded input hybrid data; and

a first interface unit for packetizing the hybrid data output from the reproducing rate conversion unit and inputting/outputting the packetized hybrid data,

wherein the disk recording/reproducing unit is operatively configured with the recording rate conversion unit and the reproducing rate conversion unit to reproduce recorded input hybrid data while effectively simultaneously recording other input hybrid data concurrently being recorded by the tape recording/reproducing unit.

2. A recording and reproducing apparatus according to claim 1, further comprising a recording/reproducing mode control unit for controlling operation modes of the tape recording/reproducing unit and the disk recording/reproducing unit.

3. A recording and reproducing apparatus according to claim 2, further comprising a signal processing unit for receiving the video data, the audio data and the additional data and outputting these data as the hybrid data, the signal processing unit comprising:

a coding/decoding unit for coding or decoding in accordance with an input/output signal;

an error correction coding/decoding unit for performing error correction coding or error correction decoding on signals which are recorded and reproduced by the tape recording/reproducing unit and the disk recording/reproducing unit, respectively;

a signal transmission unit for bidirectionally transmitting a signal between the coding/decoding unit and the error correction coding/decoding unit;

a control unit for controlling a transmission direction of the signal transmission unit; and

a control signal generation unit for generating a control signal for the control unit in accordance with a mode control signal output from the recording/reproducing mode control unit.

4. A recording and reproducing apparatus according to claim 3, wherein the coding/decoding unit comprises:

a multiplexing section for multiplexing input data on a time axis, thereby generating a single data stream;

a shuffling section for shuffling the data stream;

a compression section for compressing on the time axis data output from the shuffling section;

a deshuffling section for deshuffling data output from the compression section; and

a signal coding/decoding section for coding data output from the deshuffling section.

5. A recording and reproducing apparatus according to claim 4, further comprising a second interface unit for adding editing control information for the tape recording/reproducing unit or the disk recording/reproducing unit to data output from the first interface unit.

6. A recording and reproducing apparatus according to claim 5, further comprising a third interface unit for adding universal packetizing information conformable to a transport standard for an MPEG system to data output from the second interface unit.
