When SD is selected
1. Make coarse adjustment of the H phase by COARSE of GENLOCK PHASE (S02) and make fine adjustment by
H STEP.
2. When the BB signal is selected as reference, adjust the SC phase with the SC PHASE switch on the EN-159A/159B

2-5-3. Aspect Ratio Setting for Down-Conversion
With this unit or MSU-1000/1500, this system enables switching of aspect ratio in accordance with various systems for
the HD-SD down-conversion.
Set the aspect ratio with the MIC REMOTE connector on the rear panel or with S05:SD ASPECT of the SYSTEM
OPERATION menu. It can also be set using the maintenance menu of MSU-1000/1500.
The following four aspect ratio modes are selectable in this system.
Squeeze Converts the HD video signal to SD signal with an aspect ratio of 16 : 9 unchanged (16 : 9)
Edge crop Crops 4 : 3 video part from the HD video signal and converts it to SD signal (4 : 3)
Letterbox Fits the HD video signal with an aspect ratio of 16 : 9 into a 4 : 3 monitor frame and converts it to
SD signal (4 : 3)
(Black level is inserted above and below the picture.)
Semi-letterbox Crops 15 : 9 (or 14 : 9 or 13 : 9) video part from the HD video signal, fits it into a 4 : 3 monitor
frame, and then converts it to SD signal (4 : 3)
(Black level is inserted above and below the picture.)
Setting Aspect Ratio with the MIC REMOTE Connector
Note
If MIC REMOTE in OTHERS (M04) of the MAINTENANCE menu is set to MIC+NETWORK or MIC1 or MIC2, the
ASPECT REMOTE signal from the MIC REMOTE connector is disabled.
1. Set the DSUB-15 in I/F SETUP (C05) of the CCU CONFIGURATION menu to WF-REMOTE.
2. Set pin 12 (ASPECT REMOTE ON/OFF) of the MIC REMOTE connector on the rear panel to low level.
3. Set pins 13 (ASPECT CTL CONT1) and 14 (ASPECT CTL CONT2) of the MIC REMOTE connector according
to the aspect ratio to be converted.
