A broadcast receiving terminal, which implements a service executing method, includes a receiver operable to receive a service that uses a plurality of resources, a recording medium, and a service executor operable to execute a service that uses the plurality of resources in a service execution environment intended for the service. The terminal also includes an associater operable to associate the service execution environment with resource set information indicating the plurality of resources used by the service, when an application requests the service executor to execute the service, and a storager operable to store a plurality of service execution environments together with the associated resource set information. The terminal further includes a resource manager operable to provide, to a selected service, the plurality of resources indicated in the resource set information in the associated service execution environment.

Service executing apparatus

In the case where plural applications are executed at the same time, if each application instructs for different trick play to the same content, a difference is caused between an ideal reproduction state expected by each application and an actual reproduction state. The present invention makes it possible to keep the reproduction state unchanged as long as normal reproduction or trick play is not accepted, by including a moving picture trick play reproduction management unit which determines, in response to an instruction for one of normal reproduction and trick play, whether or not to accept, according to a rule, the instruction, and retains details specified by the instruction in the case of accepting the instruction, and a moving picture reproduction processing unit which reproduces a moving picture based on the details retained by the moving picture trick play management unit.

Recording and reproduction apparatus and recording and reproduction method

A plurality of video streams and STN_table are recorded in the local storage. Each of the plurality of video streams is a secondary video stream to be played together with a primary video stream, and includes picture data representing a child image to be displayed in Picture in Picture that is composed of a parent image and the child image. In the STN_table, entries of secondary video streams that are permitted to be played are described in the order of priority.

Recording medium, playback apparatus, method and program

Unlike the technology for a program downloaded through conventional broadcast waves, in the case of downloading a program via a network, there is a possibility that such program will be activated without noticing that the program is tampered with. For this reason, when a program is downloaded via a network, a file hierarchy for the program located on a server is constructed in a local area of a terminal. Subsequently, the authentication of the program is performed with respect to the file hierarchy constructed in the local area, and the credibility of the program is guaranteed.

Method for authenticating and executing a program

When AV playback and an operation of BD-J application are executed in conjunction with each other, the playback apparatus saves values stored by the currently executed BD-J application into a nonvolatile memory upon termination of the BD-J application or the like. Next time the playback starts, the playback apparatus restores the values to an area accessible by the BD-J application, and subsequently, activates the BD-J application.

Reproduction device, reproduction method, and program

A broadcast receiving terminal, which implements a service executing method, includes a receiver operable to receive an application, a recording medium, and a service executer operable to execute a service that uses one or more resources in a service execution environment intended for the service. The terminal also includes an associater operable to associate the service execution environment with resource set information indicating the one or more resources used by the service, when the application requests the service executer to execute the service, and a storager operable to store, into the recording medium, a plurality of service execution environments together with the associated resource set information that are associated by the associater. The terminal further includes a resource manager operable to provide, to a selected service, one or more resources indicated in the resource set information in the associated service execution environment, in the recording medium, stored by the storager.

There is provided a download execution apparatus that can prevent, at least, sudden interruption of the viewing or recording by a user when a program is downloaded. An AM includes a download source determination unit which compares current tuning information and a frequency required for downloading, and determines a download source, a tuning frequency obtainment unit which obtains tuner use situation and the frequency being tuned to by respective tuners that are in use, a download frequency obtainment unit which obtains a frequency required to download an application, a store unit which downloads and stores a program from a determined download source, a notification unit which notifies the downloading of the program to a user, and a tuning request unit which tunes a specified tuner to a frequency required for downloading a program.

Download execution apparatus

A program execution device is provided which, even when a currently executed application (program) abnormally terminates, can prevent the application from becoming unusable, and thereby improve user convenience. An MA management unit includes: an MA management unit main for receiving an instruction from an initialization subprogram and controlling the other constituent elements in the MA management unit; an XAIT obtainment analysis unit for analyzing an XAIT sent from the head end; an MA selection unit A for selecting a program to be activated, according to the XAIT analysis result; an MA activation unit for activating of the specified program; an MA monitoring unit for monitoring the operational state of the specified program and notifying when an abnormal termination has occurred; and an MA selection unit B for selecting an alternative program.
