Abstract
A remote storage digital video recorder (RS-DVR) system is disclosed. The RS-DVR system includes a network interface to communicate data between the RS-DVR system and a subscriber system via a network, a file system module coupled to the network interface, an ingest agent coupled to the file system module to receive encoded media segments that represent media content files encoded at a plurality of different bitrates; and a storage architecture coupled to the file system to store the encoded media segments, resulting in stored media segments. The RS-DVR carries out a number of functions and operations to service multiple subscribers and associated subscriber systems, such as various storage device management operations, file structure techniques, assignment of recorded media to subscribers, file system indexing, and supporting shared and per-subscriber content rights.
