To edit the frame rate sub-menu press Enter-Button for 2 seconds.
Use the Up- and Down-Buttons for navigation and select the desired frame rate by
pressing the Enter-Button.
To exit this submenu press Enter-Button.
Note
With PsF, a progressive frame is sliced into two "segments", with
the odd lines in one segment and the even lines in the other
segment. This allows for a progressive picture to be processed
through the same electronic circuitry that is used to store, process
and route interlaced video. Technically, progressive segments are
equivalent to interlaced fields, but unlike native interlaced video,
there is no motion between the two fields to make up the video
frame, both fields represent the same instant in time.
3.6 Modulation (5)
In the sub menu “Modulation” the Modulation method can be changed. The following
options are available:
• QPSK (if SD Resolution is selected)
• 16 QAM (if SD Resolution is selected)
• 64 QAM (1080p/1080i/720p/SD)
Below table shows the Bitrates for the different modulation options. FEC and Guard
Interval will be changed automatically along with the selected modulation.
Bitrate for SD Modulations
Modulation FEC GUARD BITRATE
QPSK ½ 1/32 6.03 MBit/s
16QAM ½ 1/32 12.06 MBit/s
64QAM ½ 1/32 18.09 MBit/s
