Abstract
A video on demand (VOD) gateway allows multiple incompatible and non-interoperable VOD systems to function as a single unified VOD system. A VOD gateway system includes a VOD asset gateway, a VOD session gateway, a VOD transaction gateway and a generic VOD client software program. The generic VOD client software resides in a CATV set-top box. The VOD asset gateway at the headend aggregates video inventory from multiple VOD vendor's equipment. The VOD session gateway at the headend translates a subscriber request in a generic protocol for VOD program into the proprietary protocol for a specific VOD system. The VOD transaction gateway at the headend aggregates transactions from multiple VOD vendor's equipment. In an alternate embodiment, a VOD gateway permits operators of multiple CATV systems to use multiple incompatible and non-interoperable VOD systems in each of a plurality of separate CATV systems.
