Descripción
Future high-quality consumer electronics will contain a number of applications running in a highly dynamic environment, and their execution will need to be efficiently arbitrated by the underlying platform software. The multimedia applications that currently execute in such similar contexts face frequent run-time variations in their resource demands, originated by the greedy nature of the multimedia processing itself. Changes in resource demands are triggered by numerous reasons (e.g. a switchintheinputmediacompressionformat).Suchsituationsrequirereal-timeadaptationmechanisms toadjustthesystemoperationtothenewrequirements,andthismustbedoneseamlesslytosatisfythe userexperience.Onesolutionforefficientlymanagingapplicationexecutionistoapply qualityofservice resourcemanagementtechniques,basedonassigningandenforcingresourcecontractstoapplications.
