To provide a playback device that plays back a content recorded in an optical disc in conjunction with execution of an application supplied by a server. The playback device includes a disc region code detection unit operable to detect a region code from the optical disc; an application region code estimation unit operable to estimate a region code assigned to the application based on an address of the server; a restriction unit operable, if a region code assigned to the playback device, the region code detected from the optical disc, and the estimated region code assigned to the application do not match each other, to restrict the playback of the content in conjunction with the execution of the application.

Reproduction device, reproduction method, and reproduction program

A multimedia optical disc for recording main video data which is composed of sets of frame data that is processed beforehand to allow compatibility with displays of a plurality of aspect ratios. The disc has a stream area storing streams made up of the main video data and a plurality of sets of sub-picture data, with each set of sub-picture data including a set of tel-op data and a set of coordinate information showing a display position of the set of tel-op data. The disc also includes a control area storing a plurality of pairings of a set of display mode information and a set of sub-picture indicating information. Each set of display mode information shows a species of display method according to which the frame data is to be processed for a case when the frame data decoded from the main video data is displayed at one of the plurality of aspect ratios. Each set of sub-picture indicating information shows a set of sub-picture data, out of the plurality of sets of sub-picture data in a same stream as the main video data, which includes a set of coordinate information which coincides with the species of display method shown by the display mode information.

Recording medium and playback apparatus for selecting sub-picture data according to combination of aspect ratio of display screen and type of display mode

A processing apparatus that is connected with another processing apparatus via a network, receives a request for a processing from the other processing apparatus, executes the requested processing while not performing an originally intended process of the processing apparatus, and indicates that the processing apparatus is executing the requested processing, by causing an indicator to blink on and off.

Processor

A processing apparatus is connected to a network and has a content recording/playback function. The processing apparatus stores therein, in correspondence, (i) statuses of the recording/playback process and (ii) computer virus-handling processes to be performed if a detection unit detects a computer virus. If the computer virus is detected, the processing apparatus performs one of the computer virus-handling processes in correspondence with one of the statuses of the recording/playback processes.

Processor and processing apparatus performing virus protection

A multimedia optical disc on which a variety of types of video titles are recorded and which enables a reproduction apparatus to instantly distinguish whether emulated AV functions may be performed for any of the titles. The multimedia optical disc includes a manager area which stores playback type information corresponding to the management information for each video title, with the playback type information including a first flag showing whether the present video title is expressed using one or a plurality of sets of route information and a second flag showing whether a title is expressed using any branch information.

Multimedia optical disc storing both video titles provided with AV functions and video titles with no such functions which can instantly distinguish between such kinds of titles, and a reproduction apparatus and reproduction method for such disc

A given terminal of a plurality of terminals in a network system that also includes a server apparatus, the terminals respectively corresponding to characters that exist in a virtual space. The given terminal including a display unit performing, in accordance with data stored in the sever apparatus and data stored in the given terminal, a display of a scene in the virtual space in which exits a first character whose actions are determined by the given terminal and a second character whose actions are determined by another terminal Further, the given terminal including an updating unit uploading, when a user performs an operation to form a group of characters, the displayed scene, such that performance information pertaining to the other terminal is displayed in correspondence with the second character.

Client terminal for executing multiplayer application, group forming method, and group forming program

A multimedia optical disc is provided. The multimedia optical disc includes a data area and a management information area. The data area stores a plurality pieces of video data. The management information area stores a channel table in which a plurality of logical channel numbers are respectively related to a plurality of physical channel numbers for each piece of video data. A piece of moving picture data and a plurality pieces of sub-data are interleaved in each piece of video data. The sub-data is either of audio data and sub-picture data as still pictures. The logical channel numbers are shared by pieces of video data. The physical channel numbers are used to physically identify the plurality pieces of sub-data. With this construction, it is possible to manage sub-data even when the sub-data is dealt with by a plurality pieces of video data.
