BDA Sample Application Description    Demonstrates how to construct a filter graph in DirectX 9.0 based on digital TV tuner cards that support the new Microsoft® Broadcast Driver Architecture (BDA). The sample also shows how to perform tuning based on the new Microsoft Tuning Model. The sample is discussed in more detail in the article Writing Digital TV Applications with DirectX. This sample does not use the Video Control or other TV components available on Windows® XP only.    NoteTo build this sample you must have strmbasd.lib or strmbase.lib present on your system. This library is created when you build the DirectShow base classes. For more information, see Using the DirectShow Base Classes.     Path    Source: (SDK root)\Samples\C++\DirectShow\BDA\BDASample    Executable: (SDK root)\Samples\C++\DirectShow\Bin\Bdasample.exe    每天省下一包菸的錢 愛心1000元餵飽一名非洲飢餓兒童 http://www.worldvision.org.tw/edm/30hffan/30hf1000.htm

Analog Television

Analog television differs from other video capture scenarios in several ways:

• The tuner card tunes to an analog signal, which is then digitized.
• Audio is carried in the analog signal. How the audio reaches the sound card varies depending on the hardware.
• The signal may contain additional data in the vertical blanking interval (VBI), such as closed captions (CC), World Standard Teletext (WST), and extended data services (XDS).

The following diagram shows a typical filter for television preview:

• The TV Tuner filter controls tuning.
• The TV Audio filter controls the audio decoding.
• If the tuner card has more than one physical input, the Analog Video Crossbar filter enables the application to select which input is decoded and rendered.
• The WDM Video Capture filter delivers the digitized video stream.

The Capture Graph Builder automatically inserts any filters that are required upstream from the capture filter.
This section contains the following topics:

• Analog Television Tuning
• Analog Television Audio
• Closed Captions and Teletext
