IDVB_SDT Interface
This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005 and later.
The IDVB_SDT interface enables the client to get information from a service description table (SDT). The IDvbSiParser::GetSDT method returns a pointer to this interface.
An SDT describes one or more services that are carried in a particular transport stream. The services may be carried in the same transport stream that carries the SDT, or a different transport stream.
