A set top box includes an interface to a video on demand system, the interface adapted to receive communications from one or more modulators of a modulator group of the video on demand system. The set top further includes a decoder configured to extract a modulator group identifier periodically inserted into communications directed 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 on demand system to the one or more modulators. The set top includes a video-on-demand request interface to the video on demand system, the video on demand request interface configured to output a request for video on demand data including the modulator group identifier.
