Abstract

According to one embodiment, there is provided a data processing method. The method includes reading management information indicative of a playback and display procedure, acquiring a content from a certain storage position at a timing determined based on the management information, and performing playback and display of the content at a timing determined based on the management information.

Claims

1. An information storage medium storing management information,

the management information being configured to manage main video or sub video,

the main video being capable of being played back with the sub video, and

the management information including information which relates to a position and a size of the sub video to be displayed.

2. A transfer method comprising:

receiving a request; and

transferring management information, main video, or sub video, based on the request,

the management information being configured to manage the main video or the sub video, the main video being capable of being played back with the sub video, the management information including information which relates to a position and a size of the sub video to be displayed.

3. An information reproducing method comprising:

reproducing management information, the management information being configured to manage main video or sub video,

the main video being capable of being played back with the sub video,

the management information including information which relates to a position and a size of the sub video to be displayed; and

reproducing the main video or the sub video.

4. An information recording method for recording management information on an information storage medium,

the management information being configured to manage main video or sub video,

the main video being capable of being played back with the sub video, and

the management information including information which relates to a position and a size of the sub video to be displayed,

the information recording method comprising:

receiving a request; and

recording management information relating to the request on the information storage medium.
