An incentive provision system that contributes to expanded sales of a content service and includes a user terminal and a provision device. The provision device receives, from the user terminal, request information for requesting incentive information relating to the content service. If the request information is valid, then the provision device provides the incentive information to the user terminal. A user of the user terminal enjoys using the incentive information provided from the provision device, which, in turn, motivates the user to receive the content service.

Incentive provision system

A playback apparatus and method that executes an application while playing back a digital stream. A mixer is configured to, when a flag included in a playlist is set to ON, mix an output of a click sound using sound data with an audio output of the digital stream when a user performs an operation on an application while the application is executed. When the flag is set to OFF, the mixer refrains from mixing the output of the click sound with the audio output.

The data processor includes: a receiving section, which receives an instruction on a partial deletion range including the beginning of the file; and a media control section for deleting data, the size of which is an integral number of times as large as the least common multiple of the cluster size and the packet size, from the beginning of the file within the partial deletion range.

Data processor

AVClip recorded in BD-ROM is obtained by multiplexing a graphics stream and a video stream. The graphics stream is a PES packet sequence that includes 1) PES packets storing graphics data (ODS) and 2) PES packets storing control information (PCS). In each ODS, values of DTS and PTS indicate a timing of decoding start for corresponding graphics data, and a timing of decoding end for corresponding graphics data, respectively. In each PCS, a value of PTS indicates a display timing of corresponding decoded graphics data combined with the video stream.

ABD-ROMand a local storagecontain dynamic scenarios (programs) such as a Java application and a Movie Object. A dynamic scenario reads profile information from PSRof the playback apparatus and judges whether or not the playback apparatus is an audio-only type. If it is judged that the playback apparatus is not the audio-only type, an interactive screen is displayed to perform a control to play back a digital stream according to an operation made onto the interactive screen. If it is judged that the playback apparatus is the audio-only type, a control is performed to play back a digital stream according to an operation that is made without use of the interactive screen.

Recording medium, program, and reproduction method

A playback apparatus that, when it is incorporated in a home theater system, judges via the HDMI whether an apparatus such as a speakerconnected thereto has a playback capability. If the connection partner apparatus has the playback capability, the playback apparatus inquires a user whether a decoding should be performed using a decoder embedded in the connection partner apparatus. If, in response to the inquiry, the user indicates that the decoding should be performed using the decoder of the connection partner apparatus, the playback apparatus reads a digital stream from a recording medium and outputs the read digital stream to the connection partner apparatus, by the pass-through output, regardless of a decoding capability of the playback apparatus itself.
