Abstract
A media player according to an embodiment includes: a data retriever configured to retrieve, from data recorded on a medium from which a content is run, data including an address that indicates a recording position on the medium of the content provided by the medium; and an ID determination unit configured to determine an ID for identifying the provided content in accordance with the retrieved data in order to acquire, from an external device that stores information related to the content, the information associated with the ID and related to the provided content, by communicating the ID to the external device.
Claims6
A media player comprising:
- a data retriever configured to retrieve data from a file recorded on a DVD medium from which content is run and configured to control overall behavior of the DVD medium, and configured to retrieve data from a file for controlling behavior of a video title set recorded on the DVD medium, both sets of data including an address that indicates a position of recording on the DVD medium of attribute information that is related to a unit of content provided on the DVD medium for which the position of recording varies as the unit of content is modified for recording;
- an ID determination unit configured to determine an ID for identifying the unit of content provided by the DVD medium in accordance with the data retrieved from the file for controlling the overall behavior of the DVD medium and the data retrieved from the file for controlling the behavior of the video title set, such that, given normal image content and special image content resulting from partly-modified normal image content, the ID determination unit determines an ID for the special image content that is different from the ID for the normal image content;
- and
- a related information acquisition unit configured to acquire, from an external device that stores information related to the unit of content provided by the DVD medium, information related to the unit of content provided by the DVD medium and associated with the ID determined by the ID determination unit, by communicating the determined ID to the external device.

A content ID determination method executed by a media player, comprising:
- retrieving data from a file recorded on a DVD medium from which content is run and configured to control overall behavior of the DVD medium, and configured to retrieve data from a file for controlling behavior of a video title set recorded on the DVD medium, both sets of data including an address that indicates a position of recording on the DVD medium of attribute information that is related to a unit of content provided on the DVD medium for which the position of recording varies as the unit of content is modified for recording;
- and
- determining an ID for identifying the unit of content provided by the DVD medium in accordance with the data retrieved from the file for controlling the overall behavior of the DVD medium and the data retrieved from the file for controlling the behavior of the video title set, such that, given normal image content and special image content resulting from partly-modified normal image content, an ID for the special image content that is different from the ID for the normal image content is determined, in order to acquire, from an external device that stores information related to the unit of content provided by the DVD medium, information related to the content provided by the DVD medium and associated with the ID for identifying the unit of content provided by the DVD medium, by communicating the determined ID to the external device on the medium, the information associated with the ID and related to the provided content, by communicating the ID to the external device.
A computer program embedded on a non-transitory computer-readable medium executed by a computer processor, the computer program comprising:
- a module configured to retrieve data from a file recorded on a DVD medium from which content is run and configured to control overall behavior of the DVD medium, and configured to retrieve data from a file for controlling behavior of a video title set recorded on the DVD medium, both sets of data including an address that indicates a position of recording on the DVD medium of attribute information that is related to a unit of content provided on the DVD medium for which the position of recording varies as the unit of content is modified for recording;
- a module configured to determine an ID for identifying the unit of content provided by the DVD medium in accordance with the data retrieved from the file for controlling the overall behavior of the DVD medium and the data retrieved from the file for controlling the behavior of the video title set, such that, given normal image content and special image content resulting from partly-modified normal image content, the ID determination unit determines an ID for the special image content that is different from the ID for the normal image content;
- and
- a module configured to acquire, from an external device that stores information related to the unit of content provided by the DVD medium, information related to the unit of content provided by the DVD medium and associated with the ID determined by the ID determination unit, by communicating the determined ID to the external device.
