Chapter 3 : OPERATING MODE
The OCTO device can be used in two different switching modes.
•
The
SEAMLESS MODE
, allows switching seamlessly, fading* and titling* between the "reference" COMPUTER input
and the others inputs. These ones are scaled to the same format as the "reference" COMPUTER format.
NOTE:
The inputs, which can be used as the "reference" Computer input, are the Input # 1 and # 8.
NOTE:
The "reference" Computer is not scaled.
•
The
FAST SWITCHING MODE (ultra smooth)
allows selecting an output format corresponding to your application.
All video inputs are scaled to the selected format. The switching between two inputs will go through a fade colored
transition. The output rate can be selected between 60 Hz, 75 Hz or can be synchronized onto one of the video input
frame rate in order to improve the motion picture. In this case, the output frame rate will be 50 Hz if the input is in PAL
or SECAM, and 59.94 Hz if the input is in NTSC.
