Abstract

The provisioning of a multimedia application is enhanced by using a communications protocol which defines a number of different functions and which allows a multimedia application to be segmented into a plurality of logical blocks such that a user may enter a request characterizing one such function and, in response thereto, the system performs the function with respect to a particular one of the logical blocks. The underlying multimedia system is also enhanced by arranging it so that an application provider may interact with the system via a telecommunications network for the purpose of, for example, storing the application thereon and/or "debugging" the stored application.
