This sample is the source code for a Broadcast Driver Architecture (BDA) tuner driver<!-- for Windows® 2000-->. It is provided as an example of a BDA device minidriver for the AVStream class of kernel streaming. Use the BDA tuner driver with a Philips tuner card.<P>
|
||
|
|
|
||
|
|
<H3>BUILDING THE SAMPLE</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
|
||
|
|
To build the sample, open a DDK command window, change to the BDA directory, and use the <B>build</B> command. Before you can use the sample, you need to install the Philips tuner card.
|
||
|
|
<P>
|
||
|
|
To install the tuner card, shut down the computer, insert the tuner card, and boot. The operating system uses the PhilTune.inf file to detect and install the tuner card.<P>
|
||
|
|
|
||
|
|
After the tuner card is installed, the built sample, Philtune.sys, is in the %SystemRoot%\System32\Drivers directory of the operating system.<P>
|
||
|
|
|
||
|
|
<!--Plug and Play and Power Management are not implemented in Philtune.sys. <P> -->
|
||
|
|
|
||
|
|
Building this sample produces one file: Philtune.sys. Both free and checked versions are buildable.<P>
|
||
|
|
|
||
|
|

|
||
|
|
The BDA network provider filter uses the BDA tuner driver to configure a filter in a filter graph. This filter is used to tune and demodulate a digital signal. Other filters in the filter graph capture video frames and present the video on the display.<P>

The ObjDesc.cpp file contains definitions and templates that the network provider filter uses to determine topology, to configure and change a filter instance, and to manipulate tuner and demodultor nodes. The BDA tuner driver registers these definitions and templates with the BDA support library so the library can handle most aspects of these operations. Other files of this sample define constants, structures, and classes and implement methods for those classes. <P>
