About the Device Host API

The Device Host API with UPnP technology is a framework for implementing UPnP-based device functionality on the Windows platform. Developers who are creating devices by using the Device Host API with UPnP technology (referred to as hosted devices) need only implement the device's core functionality. Developers can rely on the device host to handle the UPnP-specific details of discovery, description, control, eventing, and presentation. The device host validates incoming data from UPnP-based clients and formats all outgoing data from hosted devices according to the UPnP device architecture.

The following sections explain, in general, how the UPnP device host works:

• Implementing a Hosted Device
• Registering a Hosted Device with the Device Host
• Device Providers
• Eventing
• Presentation
