SMPTE 2022-6 Timing To Reference
The ETH1 and ETH2 timings are measured by taking the time difference between reference and the marker bits
in the S2022-6 streams. These values are displayed as values (in
µ
sec).
o
Measurement less than a field in interlaced format and less than ½ frame for progressive format will be
seen as “input is late to Reference ” (positive value).
o
Measurement higher than a field in interlaced format and higher than ½ frame for progressive format will be
seen as “input is early to reference” (negative value)
The timing of both ETH1 and ETH2 ports is reported, in
µ
sec. The range varies with the video format:
SDI Format
Range
525, 1080i59
-16683 to 16680
µ
sec
720p59, 1080p59
−8342 το 8342 µ
sec
625, 1080i50
−20000 το 20000 µ
sec
720p50, 1080p50
−10000 το 10000µ
sec
The measured value is only displayed when the both the reference and the 2022-6 stream are present and
valid; otherwise N/A is displayed.
