Abstract: A multimedia data processing system includes a memory for storing multimedia application programs and a multitasking operating system. Extensions to the operating system control data streaming from source devices to target devices to provide real-time, continuous streaming. The extensions provide central buffer management with a user buffer option, bi-level priority support for data stream handlers, support for interleaved streams, and data stream event detection and notification.

Abstract: A method of and apparatus for bridging communications between an object oriented component and a procedural programmed device driver are disclosed. Both the object oriented component and the procedural programmed device driver are both part of a data processing system. Both the method and apparatus isolate the object oriented component from the device drivers, specifically the active device driver, by encapsulating the specific device driver information associated with that particular device driver and then transporting requests or commands from the object oriented component to the specific device driver when interfacing with the device driver. The object oriented component generates an interface object that allows for opening communication or closing communication to the device driver as well as initializing the device using the information within the device driver and for controlling the device via the device driver. A transport object is also generated, which allows the transporting of data from the object oriented selected device driver to the object oriented component. This transport object also allows data flow to be controlled between the component and the selected device driver.
