Abstract: When digital image signals inputted through an inputting terminal are recorded on a disc, a medium-related information (a serial number in an TOC) of the disc, read from the disc, with a medium-related information reading section is spectrum-spread in an SS additional information generating section and then digital image signals S2 on which the spectrum-spread medium-related information is superimposed in an SS additional information superimposing section are recorded on the disc. When the signals attempt to be reproduced, the reproduction can be performed in the case wherein the medium-related information superimposed on the image signals recorded on the disc is consistent with the medium-related information of the disc on which the image signals are recorded. Thus, copying of the information signals can be limited to the copying for private use.

Abstract: A digital information reproduction apparatus for compressing frames of data so as to intermittently reproduce the data in fast-forward speed. A data re-write device retrieves a reproduction-target frame for the fast-forward reproduction and a parameter-calculation-target frame exclusively for calculation of the frame data parameters. The frames then are transferred to a RAM. A decoder determines the frame data in the RAM, calculates the parameter-calculation frame data, and decodes the reproduction frame data by use of the parameter obtained as above. The described operation prevents expending the reproduction frame data with an incorrect parameter so as to normally fast-forward reproduce the compressed data. Furthermore, the present can select a frame used in the fast forward reproduction according to a feature index so that a section subjected to the fast-forward reproduction can be easily grasped by the user.
