Abstract
A method for storing streaming media data packets in a cache includes receiving a first streaming media data packet from a streaming media server, the first streaming media data packet comprising first header data and first payload data, pre-determining a first payload checksum in response to at least a portion of the first payload data, storing at least a portion of the first header data and the first payload checksum as first packet meta data in a first data object in the cache memory, and storing the first payload data in the first data object in the cache memory, wherein the first data object is directly addressable in the cache memory via an associated object handle.
