    摘要: In a reproducing apparatus, a generator circuit for adding copy information during the vertical blanking period of a reproduced video signal output is provided, and copy information in compliance with copy information contained in the reproduced signal is added and delivered. In a recording apparatus, a detection circuit for detecting copy information in an inputted video signal is provided, and permission/inhibition of copy is controlled on the basis of the detected copy information and when copy is permitted, necessary copy information is generated and added to a recording signal.

    摘要: A recording and/or reproducing apparatus for recording and/or reproducing image signals compressed according to different compressing methods. This recording and/or reproducing apparatus includes a compressing circuit for compressing first image data according to a first image data compressing method, a selecting circuit supplied with the first image data thus compressed and encoded by the compressing circuit and second image data compressed and encoded according to a second image data compressing method and selecting any one of the first and second compressed image data, and a first error correction encoding circuit for error correction encoding the selected compressed image data. The recording and/or reproducing apparatus further includes a recording and/or reproducing circuit for recording and/or reproducing the error correction encoded data on and/or from a recording medium, a first error correction decoding circuit for error correction decoding the compressed image data reproduced by the recording and/or reproducing circuit, an image data expanding circuit for expanding the compressed image data that has been error-corrected by the error correction decoding circuit, and an output circuit for outputting the first image data expanded by the image data expanding circuit. The second image data has a bit rate not greater than that of the first image data.
