Information record controlling apparatus, information record controlling method, information reproduction controlling apparatus, information reproduction controlling method, information recording medium, information record controlling program, and information reproduction controlling program

An information reproduction controlling apparatus that administrates and controls recorded information, constituted by a plurality of information units, and controls reproduction of the recorded information, carried out with respect to each of the information units on the basis of reproduction able and disable information which stipulates whether or not reproduction is possible at an access starting position to an I (Intra-coded) picture constituting the recorded information, comprising:

• a discrimination device that refers to the reproduction enable and disable information when the recorded information, recorded on the first recording medium, is reproduced, and discriminates whether or not the information units can be reproduced from a first recording medium with respect to each of the information units;
• and
• a reproduction controlling device that obtains and reproduces the information units when it is discriminated that the reproduction is possible,
• wherein, a reproduction disable setting device sets up disable information on the reproduction able and disable information of the each of the information units in the first recording medium every after the each of the information units is recorded on the second recording medium.

An information record controlling method for controlling and administrating recorded information, constituted by a plurality of information units, and controlling move and record of the recorded information with respect to each of the information recording units on the basis of reproduction able and disable information for stipulating whether or not reproduction is possible at an access starting position to an I (Intra-coded) picture constituting the recorded information, comprising:

• a move controlling step of obtaining the recorded information, recorded on a first recording medium, with respect to each of the information units, and making the recorded information record on a second recording medium with respect to each of the information units;
• and
• a reproduction disable setting step for setting up information, indicating that the information unit cannot be reproduced from the first recording medium, with respect to each of the information units of the recorded information of the second recording medium,
• wherein, in the reproduction disable setting step, disable information is set up on the reproduction able and disable information of the each of the information units in the first recording medium every after the each of the information units is recorded on the second recording medium.
