6. AVDL Function (MFR-8SDODL)
Optional MFR-8SDODL cards allows you to use AVDL (Auto Video Delay Line) function.
In addition to expansion of phase adjustment range, Quiet Switch enables clean signal switching and
V-Fade allows you to reduce audio switching noise using Fade Out/In.
REF input and SDI input signal phases must be synchronized.
If phase adjustment fails, the video is delayed by one horizontal line.
When Quiet Switch is set to ON, only limited ancillary data, payload ID information and audio
data, is inserted.
AVDL settings should be set in the Web-based Control AVDL Settings page.
See the Web-based Control manual for more details.
6-1. Output Format
Set the video format for each MFR-8SDODL card.
Supported formats are as shown below.
1080p, 1080i, 720p / 60, 59.94, 50
1080p, 1080PsF / 30, 29.97, 23.98, 25, 24
Set the same video format as the MFR-3100EX system format.
See Sec. 6-4. “MFR-8SDODL Support Formats.”
6-2. Quiet Switch
Set Quiet Switch to ON/OFF for each MFR-8SDODL card.
Quiet Switch ON/OFF determines the ancillary data types that can be passed through in the AVDL
system.
◆ If Quiet Switch is set to OFF
All ancillary data in SDI input signals are passed through “as is” to outputs regardless of the
data packet type.
Note that, however, erroneous data may be embedded into outputs when switching signals or
connecting / disconnecting BNC cables (SDI input). If the phase difference exceeds the AVDL
adjustment range, the ancillary data insertion line is also shifted by the same amount as the
video.
◆ If Quiet Switch is set to ON
Only the following packetized ancillary data is passed through to outputs.
Payload ID information compliant to SMPTE ST352
Embedded audio compliant to SMPTE ST299-1
Ancillary data packet continuity and insertion line are guaranteed even if signal switching or
BNC cable connection / disconnection (SDI input) occurs.
V-Fade becomes available.
