Data processing apparatus, data processing method, program, program recording medium, data recording medium, and data structure

A data processing method for a data processing apparatus that processes record data recorded on a data recording medium,

• the record data containing
• encoded video data composed of video data that have been encoded every a predetermined unit that is an access unit, and
• permission information representing whether video data corresponding to encoded video data equal to or larger than the access unit are permitted to be secondarily used in the data processing apparatus,
• the data processing method comprising the steps of:
• obtaining the permission information about the video data that are being reproduced;
• determining whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information;
• capturing the video data that are being reproduced when it has been determined at the determination step that the video data that are being reproduced have been permitted to be secondarily used;
• and
• executing a process that displays a background or a screen saver using the video data captured in the capturing step.

A computer readable medium having instructions that when executed cause a computer to perform a data process for record data recorded on a data recording medium,

• the record data containing
• encoded video data composed of video data that have been encoded every a predetermined unit that is an access unit, and
• permission information representing whether video data corresponding to encoded video data equal to or larger than the access unit are permitted to be secondarily used in the computer,
• the data process comprising the steps of:
• obtaining the permission information about the video data that are being reproduced;
• determining whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information;
• capturing the video data that are being reproduced when it has been determined at the determination step that the video data that are being reproduced have been permitted to be secondarily used;
• and
• executing a process that displays a background or a screen saver using the video data captured in the capturing step.

An apparatus comprising:

• a program recording medium on which a program has been recorded, the program including instructions that when executed by a processor cause a computer to perform a data process for record data recorded on a data recording medium;
• the data recording medium having the record data containing
• encoded video data composed of video data that have been encoded every a predetermined unit that is an access unit, and
• permission information representing whether video data corresponding to encoded video data equal to or larger than the access unit are permitted to be secondarily used in the computer, and
• the processor, the processor when executing said instructions perform steps including
• obtaining the permission information about the video data that are being reproduced;
• determining whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information;
• and
• capturing the video data that are being reproduced when it has been determined at the determination step that the video data that are being reproduced have been permitted to be secondarily used;
• and
• executing a process that displays a background or a screen saver using the video data captured in the capturing step.

A data recording medium on which record data have been recorded, the record data being processed by a data processing apparatus having a processor,

• the record data containing:
• encoded video data composed of video data that have been encoded every a predetermined unit that is an access unit, and
• permission information representing whether video data corresponding to encoded video data equal to or larger than the access unit are permitted to be secondarily used in the data processing apparatus, when said processor executes said record data, said data processing apparatus becoming a special purpose computer that controls a usage condition of said video data, and
• executes a process that displays a background or a screen saver using the video data previously captured and for which permission information exists to permit the video data to be secondarily used.

A data processing apparatus that processes record data recorded on a data recording medium,

• the record data containing
• encoded video data composed of video data that have been encoded every a predetermined unit that is an access unit, and
• permission information representing whether video data corresponding to encoded video data equal to or larger than the access unit are permitted to be secondarily used in the data processing apparatus, the data processing apparatus comprising:
• a processor configured to execute instructions that program the processor to implement an obtainment mechanism configured to obtain the permission information about the video data that are being reproduced;
• a determination mechanism configured to determine whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information;
• a capture mechanism configured to capture the video data that is reproduced when the determination means has determined that the video data that are being reproduced have been permitted to be secondarily used;
• and
• an execution mechanism configured to execute a process that displays a background or a screen saver using the video data captured by the capture mechanism.
