ARIB STD-B 39 display
The ARIB STD-B.39 display shows the decoded data for video signals using
ancillary data compliant with ARIB STD-B.39. When this display is selected, the
instrument searches the signal for ARIB STD-B.39 packets using the DID/SDID
combinations defined by either the ITU or ARIB standards organizations.
