SAA7134HL
PCI audio and video broadcast decoder
6.3.2
Supporting WDM
The Windows driver is implemented as an AV-streaming class-driver and provides a
‘DirectShow’ (DS) filter with output pins for video preview, video capture and VBI, together
with a crossbar for input sources selection.
The TV tuner filter is a separate child driver and supports the control of all common Philips
CAN and Silicon tuners. The typical filter structure is shown in
Figure 7
.

PCI configuration registers
The PCI interface of the SAA7134HL complies with the PCI specification 2.2and supports
power management and Advanced Configuration and Power Interface (ACPI) as required
by the PC Design Guide 2001
The PCI specification defines a structure of the PCI configuration space that is
investigated during the boot-up of the system. The configuration registers (see
Table 12
)
hold information essential for plug-and-play, to allow system enumeration and basic
device setup without depending on the device driver, and support association of the
proper software driver. Some of the configuration information is hard-wired in the device;
some information is loaded during the system start-up.
