ARIB TR-B.22 Display and Status Screens

WFM8200 and WFM8300 Waveform Monitors
The ARIB TR-B.22 display shows the decoded data for video signals using
ancillary data compliant with ARIB TR-B.22. (See Figure 68.) When this display
is selected, the instrument searches the signal for ARIB TR-B.22 packets using
the DID/SDID combinations defined by ARIB.

The decoded ancillary data includes the following:
DID - Data Identifier of the requested packet; permissible values range from 1
to 0xFF (255) inclusive.
Type - Type of the ANC Data packet. For ARIB TR-B.22, this is always a
Type 2 packet (DID less than 0x80), as defined by SMPTE 291M. The actual
value (with parity bits added) is displayed in parentheses.
SDID - Secondary Data Identifier of the requested packet; permissible values
range from 0 through 0xFF (255) inclusive. This field only appears when
a Type 2 packet is selected (see above). The actual value (with parity bits
added) is displayed in parentheses.
