The WinFast TV2000 WDM Crossbar driver is associated with a TV tuner card manufactured by Leadtek (under the WinFast brand). This driver is part of the WDM (Windows Driver Model), which allows the TV tuner card to interface with Windows applications for tasks such as watching TV, recording TV shows, and video capture.
The Crossbar in the name refers to a crossbar switch, which is part of the video capture pipeline, enabling the routing of various video and audio sources (such as TV signals or video inputs) to the correct outputs in the driver. In essence, the WDM Crossbar driver helps configure and manage the input/output channels of the TV tuner card, allowing users to control and access video sources.
