In this paper, a hierarchical paradigm modelingboth the intramedia and the intermedia time relationships ofmultimedia sources is derived. Each multimedia source is consideredas being made up of a master monomedia source, which isindependent, and slave monomedia sources, which are dependenton the master. The paradigm takes different timescale statisticsinto account and is used to characterize intermedia relationshipsin terms of the second-order statistics of the multimedia source.Finally, the impact of the intermedia relationships on the performanceof each monomedia source making up a multimedia sourceis analyzed when a number of multimedia sources are multiplexedtogether. The error introduced in both loss and jitter performanceanalysis when intermedia relationships are not modeled is evaluatedthrough a case study. Numerical results show that this errormay be dramatically significant in many common scenarios.
