Abstract
Abstract A method and system for loading a library requested by a service requester of an application program in a computer system. The service requester issues a request to a first loader module to load the library, where the first loader module is part of the executable application program. The first loader module passes the request to a second loader module, where the second loader module is an executable distinct from the executable application program. The second loader module then loads the library. In a preferred embodiment, the first loader module is a global dynamic loader of a multicast application program and the second loader module is a global dynamic loader executable that is an executable distinct from the executable multicast application program. A media services manager of the multicast application uses the global dynamic loader and global dynamic loader executable to load and unload one or more media service providers.
