A PCI presents a specialized Application Program Interface (API) tha
20、t is related to the communications aspects of software. The present document deals with the requirements of PCIs for multimedia applications, i.e. digital applications that combine independent isochronous and asynchronous media types together. Multimedia applications can be interactive or not. They
21、may use and/or present different types of media either in context, or simultaneously or in loose conjunction with each other. Different types of applications and different types of media like audio, video, voice or images, impose different requirements onto the terminal equipment and the underlying
22、communications networks. The impact of those applications and media, and the abilities of the communications networks are studied thoroughly. The demands of the (human) users are considered carefully. The present document analyses the different requirements by applying different viewpoints, which il
23、luminate the viewpoint-specific impacts and demands. The summary of the results form a general list of requirements for PCIs for multimedia applications. Those requirements are then compared against existing PCIs. As result a detailed list of requirements for each type of PCI is obtained. Moreover,
24、the present document structures the existing and future PCIs in accordance with existing PCI models and discusses briefly the need for future extension or creation of specific PCIs. The general title of the present document reads “Generic PCI for multimedia applications“. Since this title might misl
25、ead the reader in the sense that possibly one - and only one - PCI might exist that covers all the applications needs, the reader should note that the complexity of multimedia applications disallows this approach. Several - in nature completely different - PCIs will be needed to cover the world of m
26、ultimedia applications. This becomes even more apparent, if it is considered that future multimedia applications will probably extend to run in new kinds of terminal equipment that is not even yet available. The present document identifies the Programmable Communication Interfaces (PCIs) needed for
27、today and future multimedia aware applications. It points out: - - - - what kind of PCIs are needed; what kind of features those PCIs shall provide; what kind of suitable PCIs are already defined (or standardized) by standardization bodies; how existing definitions of those PCIs should be extended t
28、o cover the needs of multimedia aware applications.
