Abstract
A mixed-media service collection for multimedia platforms allows simultaneous access to various mixed-media services for rendering multimedia content, depending on current client conditions. In one implementation, in response to the client accessing a service collection, for example, by changing channels, only some of the mixed-media services in the service collection are simultaneously actuated based on client conditions. The client conditions may include the availability of subsystems to implement services and the client's authorization to receive services. If client conditions do not allow some services in the service collection to be actuated, then other services in the service collection are available to be actuated instead.
