Compressed digital data recording and reproducing apparatus with selective block deletion

A compressed data recording and/or reproducing apparatus comprising:

• a compressed data reproducing system for at least reproducing digital data from one recording medium in which digital data is bit-compressed and recorded;
• a compressed data recording system for at least recording digital data in another recording medium in which digital data is bit-compressed and recorded;
• the compressed data recorded in said one recording medium of the reproducing system being reproduced and transmitted to the recording system, the compressed data being bit-compressed at the same or a lower bit rate and recorded in said another recording medium;
• wherein the compressed data reproduced by the reproducing system is directly transmitted or further compressed, without being expanded, so as to be transmitted to the recording system, and is recorded in the recording medium;
• wherein the compressed data is recorded with the processing block of the bit compression being selectively deleted by means of a parameter of the bit compression.
