Abstract
A method and system identify programming code that is appropriate to the architecture and capabilities of a set-top terminal in a cable television system. The appropriate programming code is identified from among a variety of code objects being broadcast from the headend facility of the cable television system. A platform identifier stored in the set-top terminal is matched to a corresponding platform identifier in an entitlement management message or other download locator message that specifies where in the transport stream from the headend a particular code object can be acquired. By acquiring the object corresponding to the message bearing a matching platform identifier, the set-top terminal acquires programming code compatible with its attributes. Additionally, the cable television system can then optimally support a varied population of set-top terminals.
