Abstract
A set top box includes an interface to a video system configured to deliver data to an individual subscriber or subset of subscribers that are part of a larger group of subscribers, wherein the data is not delivered to the other subscribers of the larger group, the interface adapted to receive communications from one or more modulators of a modulator group of the video system. The set top further includes a decoder configured to extract a modulator group identifier periodically inserted into communications directed to the set top box from the one or more modulators, the modulator group identifier unique to a physical transmission path from a headend of the video system to the one or more modulators. The set top includes a video request interface to the video system, the video request interface configured to output a request for video data including the modulator group identifier.
