4.2.3 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.
❑ Off
■ 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 0.
❑ Vertical Delay – The range is -7 – 6. The default is 0.
❑ SCH Phase Delay – The range is 0° – 360°. The default is 0°.
5. Only available with certain hardware configurations, see B.6 Front End Card Features.
