1. A computer-implemented method of processing media data from a network, the method comprising:

  • obtaining, at a system scheduler from a user input controller, an indication to process the media data;

    obtaining, at a data transfer controller, at least a portion of the media data via the network, and providing the obtained media data to a media storage manager;

    monitoring, at said data transfer controller, a varying data transfer rate associated with obtaining at least a portion of the media data;

    periodically determining, at said data transfer controller, a statistical measure of the varying data transfer rate;

    periodically sending, at said data transfer controller, the determined statistical measure to a system scheduler;

    storing, at said media storage manager, the obtained media data in a local memory;

    periodically determining, at said media storage manager, local memory status information;

    periodically providing, at said media storage manager, the determined local memory status information to the system scheduler;

    periodically determining, at said system scheduler, a real time playback duration of the media data;

    predicting, at said system scheduler, in accordance with at least the periodically determined statistical measure and local memory status information, whether processing of the media data is likely to be interrupted;

    when processing is unlikely to be interrupted, signaling, by said system scheduler, a media processing engine;

    playing back, at said media processing engine, at least a portion of the media data in real time in accordance with the signaling by said system scheduler.
