HYBRID CENTRAL/DISTRIBUTED VOD NETWORK WITH TIERED CONTENT STRUCTURE

摘要

A service network includes media servers (216) located in both the head-end station (110) and the hub stations (130). Set top boxes would be supplied VOD services from the media server (216) located in the hub station (130) nearest to the user. By distributing the servers (216) to the hub stations (130), the size of the fiber transport network associated with delivering VOD services from the central head end media server (216) is reduced.
