Patent ID: 7216170

Claim:
A computer-based method comprising: receiving, by a client device, source content comprising one or more embedded references to resources identified via unique syntactical abstractions; and determining, by the client device, actual values of the unique syntactical abstractions in syntax of the embedded references, the unique syntactical abstractions representing at least a subset of abstractions enforceable by a single schema to reference resources independent of particular criteria used by networks associated with different respective digital broadcast standards to reference deployed resources effective to allow an individual unique syntactical abstraction to be referenced to multiple deployed resources, wherein the embedded references to deployed resources are transport stream universal resource locators (TS URL), the transport universal resource locators comprising: a name space notation; an original network identifier that identifies an original carrier of a transport stream; a transport stream identifier that uniquely identifies the transport stream within a terrestrial, cable, or satellite network; a service identifier that uniquely identifies a service or a program within the transport stream; either component tags or packet identifiers, each component tag for identifying an elementary stream with the transport stream and each packet identifier for uniquely identifying the elementary stream within the transport stream and is defined in a program map table for individual elementary streams in the transport stream; and, one of an event identifier that identifies an event within the service, an application reference that uniquely identifies the application, and a path identifier that references an object in an object carousel within the service if the URL identifies a service.
