Smart carousel
Abstract:
A data carousel exists as an out-of-band carousel (OOBC), and accessed as a hidden background service from the channel map, and that discriminates against metadata that is never (or is rarely) accessed, and that is acquired in the background, filling a cache even when the subscriber is not accessing Video on Demand.
