Abstract

A reproducing apparatus includes a reproducing section picking up any signals compressed in a plurality of different compression methods from a recording medium. The recording medium records the signals compressed in a plurality of different compression methods and record management information denoting association of the signals compressed in a plurality of different compression methods with each other, respectively. A decoding section decodes the signal picked up from said recording medium, and a recording section records reproduction management information including reproduction-interruption information in the reproducing section associated with the record management information onto the recording medium.

Claims

1. A recording and reproducing system, comprising:

a recording and reproducing unit that extracts a signal from a recording medium in which (1) signals that have the same contents and are compressed in a plurality of different conditions, and (2) record management information that denotes a mutual association between said signals, are recorded, respectively;

a decoding unit that decodes said extracted signal;

a transmitting unit that transmits said extracted signal; and

a remote decoding unit that decodes said transmitted signal,

wherein said recording and reproducing unit outputs said extracted signal to said decoding unit or said transmitting unit, and records, in correspondence to said record management information, reproduction management information including reproduction-interruption information for defining a point of interruption, to allow decoding in said decoding unit or said remote decoding unit from the point of interruption.

2. The recording and reproducing system according to claim 1, wherein said recording and reproducing unit can transmit said extracted signal to said remote decoding unit, and in said transmission, based on said record management information and said reproduction management information, transmits signals after signals corresponding to said reproduction-interruption information included in said reproduction management information.

3. The recording and reproducing system according to claim 1, wherein the signals that have the same contents are compressed at the same time in the plurality of different conditions.

4. The recording and reproducing system according to claim 1, wherein signals are a plurality of audio/video (A/V) signals in which the recording and reproducing unit compresses the plurality of A/V signals having the same A/V contents, each A/V signal being compressed in at least a first compression standard defining one of the plurality of different conditions and each A/V signal being compressed in at least a second compression standard defining another of the plurality of different conditions.
