Moving image generation apparatus, moving image playback apparatus, their control method, and storage medium

A control method of a moving image playback apparatus, comprising:

• an input step of inputting stream data generated by multiplexing a plurality of object data;
• a demultiplexing step of demultiplexing the stream data into the plurality of object data;
• a playback step of playing back the object data demultiplexed in the demultiplexing step;
• a detection step of detecting COP (Copy & Output Protection) information, which is for controlling a copy count and a transmission count, of each object data demultiplexed in the demultiplexing step;
• and
• a control step of controlling a playback operation of the playback step in accordance with a detection output of the detection step.

A computer readable storage medium on which is stored a computer executable program that executes a method for a moving image playback apparatus for playing back stream data, the program comprising:

• an input step of inputting stream data generated by multiplexing a plurality of object data;
• a demultiplexing step of demultiplexing the stream data into the plurality of object data;
• a playback step of playing back the object data demultiplexed in the demultiplexing step;
• a detection step of detecting COP (Copy & Output Protection) information, which is for controlling the copy count and transmission count, of each object data demultiplexed in the demultiplexing step;
• and
• a control step of controlling a playback operation of the playback step in accordance with a detection output of the detection step.

A moving image output apparatus comprising:

• storage means for storing various object data in a scene;
• input means for inputting request data indicating a request of desired object data stored in said storage means;
• and
• output means for outputting the object data and IPMP(Intellectual Property Management & Protection) information or COP (Copy & Output Protection) information in response to the request data.
