Details of the Mask Angle and Position
Setting the Mask Angle (Area Mask Degree Set)
The angle is displayed as 12 bits and divided into 4-bit
units when increased by a magnification of 10.
Example) Setting the mask angle according to the
following parameters during NTSC
Mask Number 1
Pan Angle 135°
Tilt Angle 45°
Pan Angle:
1350

q = 5, r = 4, s = 6
Tilt angle sign bit:
If the tilt angle is positive
x = 0
Tilt Angle:

According to the setting above, if the tilt angle only is
set to -45 degrees the following codes are transmitted.
