Research on scalable MoD has resulted in many efficient schemes that involve segmentation and asynchronous broadcast of media data, requiring clients to buffer and reorder out-of-order segments efficiently for serial playout.<br />In such schemes, buffer space requirements run to several hundred megabytes and hence require efficient buffer management techniques involving both primary memory and secondary storage: while disk sizes have increased exponentially, access speeds have not kept pace at all.<br />The conversion of out-of-order arrival to in-order playout suggests the use of external memory priority queues, but their content-agnostic nature prevents them from performing well under MoD loads. In this paper, we propose and evaluate a series of simple heuristic schemes which, in simulation studies and in combination with our scalable MoD scheme, achieve significant improvements in storage performance over existing schemes. 2003-01-20 Deng, Wei Waldvogel, Marcel Janakiraman, Ramaprabhu deposit-license 2011-03-24T16:12:36Z eng Deng, Wei
