Image recording/reproducing apparatus re-compressing and re-recording recorded data and re-recording method thereof

摘要

Video of rewriting data stored in a recompression by the recording / reproducing apparatus and provided his re-compressed data recording method It is. The video recording / reproducing apparatus and outputting the first compressed data generated by compressing a digital video signal input to a first predetermined compression encoder, the first compressed data stored in the storage unit, a storage unit for storing the first compressed data by stretching the decoder to restore the output to a digital video signal, and to transfer the digital video signal output from the encoder to the decoder, the encoder is a compressed digital video signal is passed to a second predetermined compression rate to produce a second compressed data and to output the second compressed data output by a control unit that controls to be stored in the storage unit. Accordingly, it is possible to achieve a more efficient use of the recording medium.
