Abstract
A system enables connection information and content description information to be separately transmitted from a broadcaster to a receiver. Thus, the description of the content may be provided to a receiver prior to the time that the information needed to specify the connection to the service such as a channel is known. By uncoupling the content description and connection information, the assignment of connection information may be managed dynamically in the broadcast network.
Claims17
A method comprising:
- transmitting a first announcement including a content description for content arranged with at least two levels of granularity, the first announcement transmitted before any assignment of connection has been determined for the content, said first announcement including a service identifier to link with a second announcement;
- thereafter transmitting said second announcement including connection information for the content, including linking each of the granularity levels to connection information for the granularity;
- and
- transmitting the content after the first announcement and the second announcement.
1 more element
A method comprising:
- transmitting a first announcement including a content description for content, the first announcement transmitted before any assignment of connection has been determined for the content, said first announcement including a service identifier to link with a second announcement;
- thereafter transmitting said second announcement including connection information for the content that specifies the location of service in said connection information;
- and
- transmitting the content after the first announcement and the second announcement.
1 more element
An article comprising a medium to store instructions that if executed enable a system to:
- transmit a first announcement via a digital broadcast, the first announcement including a content description for content, the first announcement transmitted before any assignment of connection has been determined for the content;
- thereafter transmit a second announcement including connection information for the content;
- transmit the content after the first announcement and the second announcement;
- provide a service identifier to link said first and second announcements;
- and
- generate the second announcement using a template while the first announcement is generated.
3 more elements
A system comprising:
- a processor;
- and
- a transmitter coupled to said processor to transmit a first announcement including a content description for content, the first announcement transmitted before assignment of connection has been determined for the content, thereafter transmit a second announcement including connection information for the content, the connection information to specify the location of service, and transmit the content after the first announcement and the second announcement.
