ICCSubStreamFiltering Interface

This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.

The ICCSubStreamFiltering interface sets the filtering on the closed captioning (CC) pins of the VBICodec filter. The CC output pins on the VBICodec filter both expose this interface. Use this interface to select which CC services are delivered by each pin. The CC pins are independent, so you can select different services on each pin. For example, you might select CC1 and CC2 on one pin and extended data services (XDS) on the other.

In addition to the methods inherited from IUnknown, the IDVB_BAT interface exposes the following methods.

Method Description
get_SubstreamTypes Retrieves the list of closed captioning services this pin is delivering
put_SubstreamTypes Sets the closed captioning services the pin will deliver.
