General WG Description
Description of Work
The WG System and Transport and WG Content Referencing and Location were merged at the 17th meeting in Montreal.

The new WG System, Transport and Content Referencing is responsible for the total architecture and consistency of the TV-Anytime System. The basic goal of the group is to ensure that working TV-Anytime systems can be build using the TV-Anytime tools.

The group uses two means to achieve that goal:
  • Technical Plenary (TP): The group prepares and hosts the TP of the TV-Anytime Forum where all the technical working groups meet and discuss the major cross group and hot issues.
  • TV-Anytime Forum technical reports that describe possible systems. These documents are the ‘white papers’ of the TV-Anytime Forum and identify, next to the behaviour of TV-Anytime tools in a system, also potential other tools that are needed to buid a working system.
The WG’s mandate also includes defining requirements on the Lower Layer Transport needed for correct operation of the TV-Anytime System. These will be mandatory requirements and will enable organisations like the DVB, ATSC, ARIB and others to implement TV-Anytime in their environment.

The purpose of Content Referencing is to allow acquisition of a specific instance of a specific item of content. For example, if a consumer sees an announcement saying "there will be a new series of murder mysteries soon", they may want to instruct their Personal Digital Recorder (PDR) to record the whole series, but cannot since they do not know when the episodes are going to be broadcast. In fact, the broadcaster may not know yet either.

To provide the capability desired by the consumer, the ability is needed to refer to content (in this example a series of programs) independent of its location, whether that location is on a particular broadcast channel on some date and time, or on a file server connected to Internet, or wherever.

The TV Anytime Content Referencing Specification provides a location independent reference (called a CRID) and the process by which this CRID is resolved into times and locations where the content can be found.
