Abstract: A computer system with an architecture and protocol that facilitate ready integration with an auxiliary display device. The auxiliary display device is coupled to the computer system over a transport, such as Bluetooth, USB or TCP/IP. From an application level gadget, control of the display device is through a programming interface to a platform component. The platform component interfaces with a device driver, which has two components. One component is common and can be used with any auxiliary display device supporting the protocol, regardless of which transport is used. The second component is transport specific. The second component processes data streams representing packets according to the protocol, conveying the packets as data in accordance with the format of the transport. The second component may be simple because it is not required to perform any processing specifically associated with the display functions or protocol.

Abstract: In a main computer system coupled to an auxiliary display device, described is an interface set for implementation by an auxiliary display device driver, to couple the driver to an auxiliary display platform. Commands received from the auxiliary display platform may be handled by code external to the driver, such as a class extension object. For example, the class extension object may interpret and/or translate commands received from the auxiliary display platform into a format understood by the driver code. The auxiliary display device driver may then provide corresponding command information including data to the auxiliary display device via the transport. Event data may be returned from the auxiliary display device driver via the interface set to the class extension object, such that corresponding event information, e.g., received at the auxiliary display device, may be returned to the auxiliary display platform.
