MPEG2_FILTER2 structure (mpeg2structs.h)

The MPEG2_FILTER2 structure specifies criteria for matching MPEG-2 section headers.

Members

bVersionNumber

The version number of the structure. This value must be 2 or higher.

wFilterSize

The size of the structure data, excluding any padding bytes. Set this field equal to the constant MPEG2_FILTER_VERSION_2_SIZE.

fUseRawFilteringBits

If TRUE, the Filter and Mask members specify the filtering criteria as a pair of bit masks, and the remaining members of this structure are ignored. If FALSE, the Filter and Mask members are ignored, and the other structure members give the filtering criteria.

Filter[16]

A 16-byte bit mask, which contains the bit values to match in the section header.

Mask[16]

A 16-byte bit mask. For each bit, if the value in Mask is 0, the corresponding bit in Filter is matched against that bit in the section header. If the value in Mask is 1, that bit in the section header is ignored.

fSpecifyTableIdExtension

If TRUE, the table_ID_extension field in the header must match the value of the TableIdExtension structure member. Otherwise, the table_ID_extension field is ignored.

TableIdExtension

A value for the table_ID_extension field.

fSpecifyVersion

If TRUE, the version_number field in the header must match the value of the Version member. Otherwise, the version_number field is ignored.

Version

A value for the version_number field.

fSpecifySectionNumber

If TRUE, the section_number field in the header must match the value of the SectionNumber member. Otherwise, the section_number field is ignored.

SectionNumber

A value for the section_number field.

fSpecifyCurrentNext

If TRUE, the current_next_indicator bit in the header must match the value of the fNext member. Otherwise, the current_next_indicator field is ignored.

fNext

A value for the current_next_indicator bit. You can use the MPEG_CURRENT_NEXT_BIT enumeration type to specify this value.

fSpecifyDsmccOptions

If TRUE, the Dsmcc member contains additional filtering criteria for the DSM-CC portions of the section header. Otherwise, the Dsmcc member is ignored.

Dsmcc

A DSMCC_FILTER_OPTIONS structure that contains additional filtering criteria for the DSM-CC portions of the section header.

fSpecifyAtscOptions

If TRUE, the Atsc member contains additional filtering criteria. Otherwise, the Atsc member is ignored.

Atsc

An ATSC_FILTER_OPTIONS structure that contains additional filtering criteria.

bVersion1Bytes[124]

fSpecifyDvbEitOptions

If TRUE, the Dvb_Eit member contains additional filtering criteria. Otherwise, the Dvb_Eit member is ignored.

DvbEit

An DVB_EIT_FILTER_OPTIONS structure that contains additional filtering criteria.
