1. A remote storage digital video recorder (RS-DVR) system comprising:

  • 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 a media content file encoded at a plurality of different bitrates, wherein the encoded media segments include a respective set of encoded media segments corresponding to each of the plurality of different bitrates, and wherein each of the encoded media segments has a time range relative to the media content file; and

    a plurality of memory storage devices coupled to the file system to store the encoded media segments on behalf of the subscriber system as a single logical file across the plurality of memory storage devices in accordance with a distribution scheme influenced by the plurality of different bitrates and time ranges of the encoded media segments, wherein;

    each encoded media segment of the encoded media segments corresponds to a partial period of playback time of the media content file; and

    each encoded media segment of the encoded media segments of the single logical file is not stored together with another encoded media segment of the encoded media segments of the single logical file having a different bitrate of the plurality of different bitrates and an overlapping partial period of playback time on a common memory storage device of the plurality of memory storage devices.
