IATSC_VCT::GetRecordIsOutOfBandBitSet

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

The GetRecordIsOutOfBandBitSet method queries whether the out_of_band bit is set for a particular record in the VCT.

Syntax

  HRESULT GetRecordIsOutOfBandBitSet(
  DWORD  dwRecordIndex,
  BOOL*  pfVal
);

Parameters

dwRecordIndex

[in]  Specifies the record number, indexed from zero. Call the IATSC_VCT::GetCountOfRecords method to get the number of records in the VCT.

pfVal

[out]  Receives a Boolean value. The value is TRUE if the out_of_band bit is set, indicating that this channel is carried on an out-of-band physical transmission channel. Otherwise, the value is FALSE.

Return Values

The method returns an HRESULT. Possible values include those in the following table.

Return code Description
E_POINTER NULL pointer argument.
MPEG2_E_NOT_PRESENT The table does not contain an out_of_band bit.
MPEG2_E_OUT_OF_BOUNDS Index out of bounds.
S_OK The method succeeded.

Remarks

This bit applies only to cable VCTs. If the VCT is a terrestrial VCT, the method returns MPEG2_E_NOT_PRESENT.
