Abstract

[Object] To appropriately control simultaneous presentation of broadcast content and an application.
[Solving Means] The information processing apparatus includes: a broadcast content processor configured to receive and process broadcast content; and a controller configured to obtain an application information table, the application information table (XML-AIT) storing an application identification descriptor 24 as information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously, and to determine if it is possible to present the application and the broadcast content simultaneously or not.

First claim

The invention claimed is:

1. An information processing apparatus, comprising:
a broadcast content processor to receive and process broadcast content; and
a controller to obtain an application information table, the application information table storing information necessary to start an application and information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously, and to determine if it is possible to present the application and the broadcast content simultaneously or not,
the information specifying broadcast content includes a channel identifier, an event identifier, a first flag, and a second flag,
the channel identifier specifying a channel, the event identifier specifying an event, the first flag defining if one or both of the channel identifier and the event identifier are to be treated as being allowed to be presented with the application simultaneously or to be treated as not being allowed to be presented with the application simultaneously, and the second flag defining if availability of simultaneous presentation of the application and the broadcast content is determined for each channel or for each combination of the channel and the event, and
the controller utilizes the first flag and the second flag to determine if it is possible to present the application and the broadcast content simultaneously or not.

2. An information processing method, comprising:
receiving and processing, by a broadcast content processor, broadcast content; and
obtaining, by a controller, an application information table, the application information table storing information necessary to start an application and information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously, and determining if it is possible to present the application and the broadcast content simultaneously or not,
the information specifying broadcast content includes a channel identifier, an event identifier, a first flag, and a second flag,
the channel identifier specifying a channel, the event identifier specifying an event, the first flag defining if one or both of the channel identifier and the event identifier are to be treated as being allowed to be presented with the application simultaneously or to be treated as not being allowed to be presented with the application simultaneously, and the second flag defining if availability of simultaneous presentation of the application and the broadcast content is determined for each channel or for each combination of the channel and the event, and
the determining utilizes the first flag and the second flag in determining if it is possible to present the application and the broadcast content simultaneously or not.

3. A non-transitory computer readable medium having stored thereon a program, which when executed causes a computer to function as:
a broadcast content processor to receive and process broadcast content; and
a controller to obtain an application information table, the application information table storing information necessary to start an application and information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously, and to determine if it is possible to present the application and the broadcast content simultaneously or not,
the information specifying broadcast content includes a channel identifier, an event identifier, a first flag, and a second flag,
the channel identifier specifying a channel, the event identifier specifying an event, the first flag defining if one or both of the channel identifier and the event identifier are to be treated as being allowed to be presented with the application simultaneously or to be treated as not being allowed to be presented with the application simultaneously, and the second flag defining if availability of simultaneous presentation of the application and the broadcast content is determined for each channel or for each combination of the channel and the event, and
the controller utilizes the first flag and the second flag to determine if it is possible to present the application and the broadcast content simultaneously or not.

4. An application information table transmitting apparatus, comprising:
a table transmitting section to transmit an application information table, the application information table storing information necessary to start an application and information specifying broadcast content, the broadcast content being capable of being presented with the application simultaneously,
the information specifying broadcast content includes a channel identifier, an event identifier, a first flag, and a second flag, and
the channel identifier specifying a channel, the event identifier specifying an event, the first flag defining if one or both of the channel identifier and the event identifier are to be treated as being allowed to be presented with the application simultaneously or to be treated as not being allowed to be presented with the application simultaneously, and the second flag defining if availability of simultaneous presentation of the application and the broadcast content is determined for each channel or for each combination of the channel and the event.
