7.3.2
The WDM driver for Windows 98 and Windows 2000 (see
Fig.7) is a kernel-mode driver that implements a Kernel
Streaming (KS) filter with output pins for audio, video
preview, video capture and VBI, together with a crossbar

UPPORTING
EVICE DRIVER
Device access is contained within a VxD. The Video for Windows (VfW) capture driver interface is a
16-bit user-mode interface.
Device access is contained in a kernel-mode driver. The VfW capture driver interface is a 32-bit
user-mode interface.
Device access is contained with a kernel-mode Windows Driver Model (WDM) driver. The capture
driver interface is also kernel-mode WDM.
The driver is binary-compatible with the Windows 98 driver.

DRIVER SUPPORT
All platform related drivers support the following:
for input source selection and optional connections for
other on-board devices as child drivers. The WDM driver
is implemented as a stream class mini-driver. It also
exposes the external interfaces to support the user-mode
34API DLL. Custom applications and debug tools will
continue to work without the need to load different drivers.
Video preview and capture interfaces
Audio control and audio capture interfaces
Custom application interface, that enables the
development of specialized applications in cases where
the published Windows Application Program Interface
(API) such as WDM or VfW is not sufficient.
