Delivery of MHEG-5 in a DAVIC ADSL network

Abstract

We analyze the delivery of an object-oriented multimedia content model, namely MHFG-5 (Multimedia Hypermedia Expert Group), for interactive multimedia applications in a DAVIC-compliant ADSL access network using low-cost memory-constrained set top units. We present detailed latency budgets for MPEG-2 DSM-CC-based transactions including STU configuration, engine download, and application and scene activation. We use simulation and analysis to assess the tradeoffs in memory management and application response time. We discuss our implementation of a subset of DSM-CC and MHEGJ, and latency measurements for presenting MHEG objects. The results are formulated as graphs which can be used by an application designer when encoding an MHEG application.
