This sample is the source
code for a generic tuner sample Broadcast Driver Architecture (BDA) driver for
Windows® XP. It is provided as an example of a BDA device minidriver
for the AVStream class of kernel streaming and to
give hardware vendors assistance in writing their own BDA minidrivers.
This sample does not have any associated hardware. The driver is designed to work the sample BDA
Capture driver.
To build the sample, open
a DDK command window, change to the BDA directory, and use the build
command. The build command gets instructions on how to build from the Sources file.
This sample can be built
as either an ATSC sample or a DVB-S sample.
To select the flavor of sample simply uncomment the appropriate MACRO
definition (ATSC_RECEIVER or DVBS_RECEIVER) in BDATuner.h. Make sure only one of the receiver type MACROs is defined. Building
this sample produces one file: BDATuner.sys. Both
free and checked versions can be built.
The best way to use the
sample BDA tuner driver is to build both BDATuner.sys
and BDACap.sys.
Copy these to a directory along with the sample BDA tuner INF (BDATuner.inf), sample BDA capture INF(BDACap.inf), and software receiver INF (BDASWRcv.inf). Start the installation by right clicking BDASWRcv.inf and then left clicking Install. Follow the direction to complete installation
of both the sample BDA tuner and sample BDA capture drivers.
GraphEdit uses the BDA sample generic tuner
driver to configure a filter for the driver in a filter graph. This BDA sample
generic tuner filter does not perform any specific functions. You can connect
the BDA ATSC or DVB-S network provider filters to the input pin of the generic
filter. You can connect the BDA capture filter to the output pin of the BDA
tuner filter.
The sample BDA capture appears
under "BDA Receiver Components" as "Sample BDA Capture". The sample BDA tuner appears under “BDA
Source Filters” as “Sample BDA Tuner Filter”.
The ATSC Network Provider appears under “BDA Network Providers” as “Microsoft
ATSC Network Provider”. The DVB-S
Network Provider appears under “BDA Network Providers” as “Microsoft DVBS
Network Provider”.
Many properties can be set
on your filter by right-clicking the Network Provider filter in GraphEdt and selecting Properties. The displayed property pages allow for the
creation and submission of tune requests that ultimately result in properties
being set on your driver. Note that, if
you are testing a DVB-S driver, you should use the DVBS Network Provider
property pages to create ad DVB-S tuning space called “MYDVB”. To access these
properties you must first run Regsvr32 on PropPage.dll which is delivered in
the Direct Show SDK. You can also create
a plugin to directly access and configure the BDA
sample generic tuner filter.
