Abstract
A playback device reads a BD-J application from a BD-ROM and runs the BD-J application. The BD-J application causes, by using a socket connection API, the digital copy module of the playback device to execute copying of a protected content for portable terminals to a removable recording medium and setting of a resume playback point on the copied content. The resume playback point is specified by the BD-J application according to playback time information read from the PSR set.
Claims13
A playback apparatus for playing back a first content recorded on a first recording medium, the playback apparatus comprising:
- a reading unit configured to read an application recorded on the first recording medium;
- a platform unit configured to execute the application;
- a copy unit configured to execute copy processing of a second content recorded on the first recording medium;
- and
- a register configured to store a parameter indicating a playback point on the first content, the playback point on the first content updated as the playback of the first content progresses,
- wherein the platform unit includes a communication programming interface for use by the application, and
- the application (i) reads the parameter from the register, (ii) establishes a socket connection with the copy unit by using the communication programming interface, and (iii) causes the copy unit to execute the copy processing via the socket connection, the copy processing including copying of the second content to a second recording medium and setting of a playback point on the copied second content, the playback point on the copied second content specified by the application according to the parameter.
A non-transitory recording medium that has recorded thereon a computer readable program for causing a computer to playback a first content recorded on a first recording medium, the computer readable program causing the computer to execute operations comprising:
- reading an application recorded on the first recording medium;
- causing a platform unit of the computer to execute the application;
- and
- causing a copy unit of the computer to execute copy processing of a second content recorded on the first recording medium wherein
- the application (i) reads a parameter indicating a playback point on the first content from a register of the computer, the playback point on the first content updated as the playback of the first content progresses, (ii) establishes a socket connection with the copy unit by using a communication programming interface included in the platform unit, (iii) causes the copy unit to execute the copy processing via the socket connection, the copy processing including copying of the second content to a second recording medium and setting of a playback point on the copied second content, the playback point on the copied second content specified by the application according to the parameter.
A playback method for executing playback of a first content recorded on a first recording medium, the playback method comprising:
- reading an application recorded on the first recording medium;
- causing a platform unit of a computer to execute the application;
- and
- causing a copy unit of the computer to execute copy processing of a second content recorded on the first recording medium wherein
- the application (i) reads a parameter indicating a playback point on the first content from a register of the computer, the playback point on the first content updated as the playback of the first content progresses, (ii) establishes a socket connection with the copy unit by using a communication programming interface included in the platform unit, (iii) causes the copy unit to execute the copy processing via the socket connection, the copy processing including copying of the second content to a second recording medium and setting of a playback point on the copied second content, the playback point on the copied second content specified by the application according to the parameter.
A non-transitory recording medium that has recorded thereon:
- a first content that is subject to playback;
- and an application, wherein
- the application is executed by a platform unit of a playback apparatus, the platform unit including a communication programming interface used by the application
- the application (i) reads a parameter indicating a playback point on the first content from a register of the playback apparatus, the playback point on the first content updated as playback of the first content progresses, (ii) establishes a socket connection with a copy unit of the playback apparatus by using the communication programming interface, (iii) causes the copy unit to execute copy processing of a second content, recorded on the non-transitory recording medium that is different from the first content, via the socket connection, the copy processing including copying of the second content to another recording medium and setting of a playback point on the copied second content, the playback point on the copied second content specified by the application according to the parameter.
