PCR Configuration
Use the PCR Configuration menu to set up the clock synchronization parameters for the
modulated program.
The PCR Configuration menu provides the following options:
■
Clock Source
– selects the clock source for the synchronization of the modulation of the
audio and video streams in the program. You cannot change the clock source when A/V
Sync is set to 5 ms. Options:
❑
Original PCR
❑
Decoder Clock
❑
Genlock
5
■
A/V Sync
– selects the audio to video synchronization parameter. Options:
❑
Frame
– Select this parameter to limit the audio/video sync jitter to 1 frame.
❑
5 ms
– Select this parameter to limit the audio/video sync jitter to 5ms when the clock
source is set to Original PCR.
❑

■
A/V Offset Compensation
– This menu only displays when A/V Sync is set to 5 ms. The
range is -20 to 20 ms. The default is
0
.
■
Genlock Type
– This menu only displays when Clock Source is set to Genlock. Use this
menu to sync with the incoming signal. The options are:
❑
Analog
– Analog genlocking supports PAL B/G, NTSC, 720P (50, 59, 60 Hz) and
1080i (50, 59, 60 Hz). The main output must be configured to PAL B/G or NTSC. The
configuration options are under the Analog Genlock Configuration menu.
❑
Digital
– Digital genlocking supports PAL B/G, NTSC, 720P (50, 59, 60 Hz) and 1080i (50,
59, 60 Hz). The main output must be configured to PAL B/G, NTSC, 720P (50, 59, 60 Hz)
or 1080i (50, 59, 60 Hz).
The default is
Digital

■
Analog Genlock Configuration
– this menu only displays when Genlock Type is set to
Analog
. Options:
❑
Horizontal Delay
– The range is 0 – 1728 in 37 ns or 27 MHz ticks. The default is
