IATSC_STT Interface

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

The IATSC_STT interface enables the client to get data from a system time table (STT), which defines the current data and time of day. The IAtscPsipParser::GetSTT method returns a pointer to this interface.

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

Method Description
GetCountOfTableDescriptors Returns the number of descriptors in the STT.
GetDaylightSavings Returns the Daylight Savings Time Control bytes.
GetGpsUtcOffset Returns the offset between GPS time and UTC.
GetProtocolVersion Returns the protocol version of the table.
GetSystemTime Returns the current system time.
GetTableDescriptorByIndex Returns a descriptor for the STT.
GetTableDescriptorByTag Searches the STT for a descriptor with the specified descriptor tag.
Initialize Initializes the object.
