For SD, N/A is displayed.
Status - Indicates whether packet(s) of the desired type are present in the video; also indicates Checksum or CRC errors.
Checksum - Indicates the checksum word that was recovered from the acquired packet.
Should be - Indicates the checksum word computed by the instrument, based on the packet's data.
Format - Indicates the name of the ancillary data type or standard.
Inter-Station Ctrl Header - A header byte indicating packet continuity, and the presence or absence of the error correcting
code.
Transmitting Station Code - The name of the transmitting station. The instrument supports the display of Japanese
characters.
Transmitting Station Time - The broadcast time at the transmitting station.
Current Video Mode - The video format of the current program.
Next Video Mode - The video format of the next scheduled programming.
Video Mode Countdown - A countdown timer indicating an upcoming change in video mode, which counts down from
254 (0xFE). A value of 0xFF indicates that no format change is pending within the next several seconds.
Current Downmix/Audio Mode - Indicates the audio downmix and soundstage configuration of the current program.
Next Downmix/Audio Mode - Indicates the audio downmix and soundstage configuration of the next scheduled program.

changes in the program; usage is user-defined.
Trigger Bits (Q24..Q17 Q32..Q25) - Together with trigger bits Q8..Q1 Q16..Q9; 32 bits that can be used to indicate
changes in the program; usage is user-defined.
Trigger Counter - Increments when bits Q1-Q4 go from 0 to 1. Wraps from 254 (0xFE) to zero. Value of 0xFF indicates
the trigger counter is not used.
Trigger Countdown - A countdown timer indicating an upcoming change in trigger bits Q1-Q4, which counts down from
254 (0xFE). A value of 0xFF indicates that no format change is pending within the next several seconds.
Status Bits (S8..S1 S16..S9) - 16 user-defined status bits.
