Claims11
A reproducing apparatus comprising:
- a reproducing means for reproducing an information signal from a solid-state memory, the information signal being composed of a plurality of blocks each of which has a compressed image signal and additional information for disabling a normal reproduction of the compressed image signal stored in the solid state memory;
- and
- expanding means for expanding an information amount of the compressed image signal reproduced from the solid-state memory, wherein the normal reproduction of the image signal from the solid-state memory is disabled according to the additional information of the plurality of blocks.
A recording apparatus comprising:
- compressing means for compressing an information amount of an image signal;
- and
- recording means for forming an information signal composed of a plurality of blocks each of which has the compressed image signal and additional information for disabling a normal reproduction of the compressed image signal and for recording the information signal into a solid-state memory, wherein the normal reproduction of the compressed image signal from the solid-state memory is disabled according to the additional information of the plurality of blocks.
A recording apparatus comprising:
- input means for inputting an image signal representing a moving image;
- generating means for dividing the input image signal every predetermined period and for obtaining an information signal composed of a plurality of blocks each of which has the divided image signal and additional information for disabling a normal reproduction of the image signal by adding the additional information to the divided image signal;
- and
- recording means for recording the information signal in a recording medium, wherein the normal reproduction of the image signal by said reproducing means from the recording medium is disabled according to the additional information of the plurality of blocks.
