摘要:
An aggregation system for aggregating contents recorded on a plurality of recording mediums and recording them onto another recording medium while protecting the copyrights of the contents is provided. An aggregation system (1) includes an aggregation apparatus (16) and a reproduction apparatus (17). The aggregation apparatus (16) obtains a main content from an optical disc (11), obtains a sub content from a memory card (12), and aggregates the obtained main content and sub content and records them onto a portable medium (13). The reproduction apparatus (17) obtains the main content from the optical disc (11), obtains reproduction control information for controlling reproduction of the main content, and reproduces the main content recorded on the optical disc (11) based on the reproduction control information.

An optical disk includes an audio data storage area for storing audio data; a still picture data storage area for storing a plurality of pieces of still picture data; and a management area for storing reproduction control information for controlling reproduction of the audio data and the plurality of pieces of still picture data. The reproduction control information has flag information representing specified still picture data among the plurality of pieces of still picture data.

To provide a sub-picture unit generation apparatus for generating a plurality of sub-picture units that compose a sub-picture stream which is interleaved with a video stream into a system stream, each sub-picture unit including a subtitle image that is to be superimposed on moving images reproduced from the video stream. The sub-picture unit generation apparatus includes an attribute storage unit for storing a display attribute that shows a base position for arranging each subtitle image, a character string storage unit for storing a plurality of subtitle character strings, a subtitle image generation unit for generating a subtitle image from one of the plurality of subtitle character strings stored in the character string storage unit, a display position determination unit for determining a display position of the subtitle image according to the display attribute, and a sub-picture unit generation unit for generating a sub-picture unit that includes the subtitle image and display position data showing the determined display position.

Provided is a video processing device that quickly identifies a distribution mode of a stream of display data, e.g., subtitles, and reproduces the data according to the distribution mode. The video processing device receives a transport stream including additional information and a data stream of display data to be displayed along with a 3D video, the additional information indicating whether the transport stream further includes left-view and right-view data streams generated from left-view and right-view data used for displaying the display data; determines whether the transport stream includes the left-view and the right-view data streams based on the additional information; and reproduces the left-view and the right-view data from the left-view and the right-view data streams when the transport stream includes the left-view and the right-view data streams, and reproduces alternative left-view and right-view data when the transport stream does not include the left-view and the right-view data streams.

A recording medium has authoring data recorded thereon. The authoring data has a plurality of formats. Data items common to all the plurality of formats include, a content, a content key for encrypting the content, a hash value of the content, a media key for encrypting the content key, and revocation information for revoking an unauthorized device from using the media key. The plurality of formats include a first format and a second format. In the first format, the content is not encrypted and each of the content key, the hash value, the media key, the revocation information is dummy data. In the second format, the content is encrypted and each of the media key and the revocation information is dummy data.

When playing an AV Clip recorded on a BD-ROM, a judgment is made, for each elementary stream, which of a plurality of predetermined conditions the elementary stream satisfies. The plurality of predetermined conditions include (a) a condition that a playback apparatus has a capability of playing the elementary stream, (b) a language attribute of the elementary stream matches a language setting of the playback apparatus, and (c) a channel attribute of the elementary stream is surround sound and the playback apparatus has a surround output capability. The playback apparatus assigns a priority to each elementary stream based on which conditions the elementary stream satisfies, selects an elementary stream having a highest priority, and plays the selected elementary stream.

A data generating apparatus 100 includes: an acquiring unit 101 configured to acquire a frame image; a setting unit 109 configured to set prohibition information showing a region on the frame image in which superimposition of an additional image is prohibited, the prohibition information being used when a playback apparatus superimposes the additional image on the frame image for playback; and a multiplexing unit 104 configured to multiplex the frame image and the prohibition information to generate data. A receiving apparatus 400 includes: a receiving unit 401 configured to receive data having been generated by multiplexing the frame image and the prohibition information; a separating unit 402 configured to separate the frame image and the prohibition information from the data; an acquiring unit 409 configured to acquire the additional image; and a superimposing unit 407 configured to superimpose the additional image on the frame image based on the prohibition information.

A video processing device receives at least a supplementary display object playback stream and a data block, the supplementary display object playback stream containing an encoded supplementary display object to be displayed along with a 3D video image, and the data block including identifying information for 3D display of the supplementary display object by a processing unit. Before the content of the supplementary display object playback stream is referred to, the identifying information is extracted from the data block and the processing unit for 3D display of the supplementary display object is determined. The determined processing unit processes the supplementary display object playback stream to create and output a right-view supplementary display object and a left-view supplementary display object.

When reading an AV Clip which is formed by multiplexing a plurality of elementary streams from a BD-ROM and playing back the AV Clip, an STN_table that lists an entry of each elementary stream is acquired from PlayList information on the BD-ROM. For each elementary stream shown in the STN_table, a judgment is made as to whether the elementary stream satisfies a predetermined condition. Of all elementary streams judged as satisfying the predetermined condition, an elementary stream having a highest entry in the STN_table is selected and played back.
