A Resource Identification Mechanism for Interactive DTV Systems

This paper describes a resource identification mechanism for interactive applications running on broadcast digital TV systems. The proposed mechanism relieves application authors from having knowledge of the addressing scheme used to identify resources in DTV presentation environments (set-top boxes or other receivers) and transport schemes based on MPEG-2 Systems and DSM-CC standards. The proposal comes from the reference middleware defined for the Terrestrial DTV Brazilian System, but can be applied to other DTV systems.
