Recording and reproducing apparatus for reproducing time-base compressed signals dependent on the time-base compression implemented

A recording/reproducing apparatus for digitally recording and reproducing an analog or digital picture/audio signal, comprising:

• first input means for inputting time base compressed digital data to which compression coding and time base compression processing have been implemented;
• first recording signal processing means for demodulating and performing error correction on the time base compressed digital data;
• second input means for inputting an analog signal;
• an analog-to-digital converter to convert the input analog signal into predetermined digital data;
• second recording signal processing means for compression-coding at least the predetermined digital data;
• a changeover switch for receiving an output of the first recording signal processing means and an output of the second recording signal processing means;
• control means for controlling said changeover switch based on the input analog signal or the input time base compressed digital data;
• parity generator means for adding parity to the data output from the first or second recording signal processing means, which is received as an output of the changeover switch;
• channel coding means for modulating an output of the parity generator means;
• recording means for recording the modulated signal onto a recording medium;
• read out means for reading out the digital data from the recording medium, said read out means being controlled by said control means to read out the digital data at a speed slower than a recording speed based on the time base compression processing that was implemented to time base compress the digital data;
• and
• output means for outputting the digital data read out from the recording medium.

A reproducing apparatus for reproducing prerecorded analog or digital picture/audio data, said data having been selectively time base compressed, comprising:

• reproducing means for reproducing the prerecorded data from a recording medium at a speed slower than a recording speed, the reproducing speed being based on processing that had been implemented to time base compress the prerecorded data;
• channel decoding means for demodulating the reproduced data;
• error correction means for performing error correction on the demodulated data;
• a changeover switch for receiving the error corrected data;
• first reproduction signal processing means connected to the changeover switch to reproduce the time base compressed data;
• and
• second reproduction signal processing means connected to the changeover switch to reproduce non-time base compressed data;
• and
• control means for controlling the changeover switch based on discrimination data recorded on the recording medium and for controlling a drive speed of a recording medium drive means.
