Abstract

Still today, diagnosing a problem withmultimedia resources, such as video and sound cards, isinsufficiently automated. These resources thereforecannot be accurately managed. One reason for this is the lack of their thorough modeling. In this paper,we fulfill this need, by proposing a generic informationmodel, which we further apply to an MPEG2 video codec.We highlight the main characteristics of this kind of codec, identify parameters thatinfluence these characteristics, and reveal some of thetrade-offs that the application developer can considerin order to design efficient software for MPEG2 codecs. In addition to the benefits of this modelingfor the user and the application developer, we also showhow useful it could be for the providers of distributionservices, such as "live" video transmission. These providers can use our model to achieveresource management on an end-to-end basis.
