Using the ARIB Di
splays
Stream - For HD (SMPTE 292M), indicates whether the ancillary packet was acquired from the Y or C data s treams.
For SD, N/A is d i
splayed.
Status - Indica
tes whether packet(s) of the desired type are present in the video; also indicates Checksum or CRC errors.
Checksum - Indi
cates the checksum word that was recovered from the acquired packet.
Should be - Indi
cates the checksum word computed by the instrument, based on the packet’s data.
Format - Indica
tes 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 v
alue of 0xFF indicates that no format change is pending within the next several seconds.
Current Downm
ix/Audio M ode - Indicates the audio downmix and soundstage configuration of the current program.
Next Downmix/
Audio M ode - Indicates the audio downmix and soundstage configuration of the next scheduled program.
Audio Mode Cou
ntdown - A countdown timer indicating an upcoming change in audio mode, which c ounts down from
254 (0xFE). A value of 0xFF indicates that no format change is pending within the next several seconds.
Trigger Bits (Q8..Q1 Q16..Q9) - Together with trigger bits Q24..Q17 Q32..Q 25, 32 bits that can be used to indicate
changes i n the program; usage is user-defined.
Trigger Bits (Q24..Q17 Q32..Q 25) - Together with trigger bits Q8..Q1 Q16..Q9; 32 bits that can be used to indicate
changes in th
e program; usage is user-defined.
Trigger Coun
ter - 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.
Error Correcting Code - A six-word, Reed-Solomon error correcting code, which is used to verify the integrity of the ARIB
B.39 or ITU-R
BT.1685 packet.
