High Definition (HD) Digital Output parameters:
■ Video Format – selects the video format.
Options: 720p@50, 720p@59, 720p@60, 1080i@50, 1080i@59, 1080i@60.
■ Aspect ratio Conversion – selects the aspect ratio conversion for the output stream. To be
performed if the incoming stream aspect ratio is not the same as the configured output
aspect ratio.
Options:
❑ Pillarbox (Side-bars)
❑ Full Screen
❑ Letterbox
❑ Center-cut
■ CV Mon Output (SD) – sets the parameters for the SD analog (CV) monitoring output,
consisting of SD video format, SD aspect ratio and aspect ratio conversion.
Advanced video processing parameters:
■ Blanking – selects the response for blanking mode (underflow). Options: Black, Last Field,
Last Frame.
■ Buffer Management – Options:
❑ Normal
❑ Low Delay – Select this option to use Low Delay mode.
❑ Additional Image Processing
PCR Parameters Tab
The PCR parameters tab provides the EMS user the following information and set-up
capabilities:
■ Clock Source – You can select one of the following clock sources:
❑ Original PCR
❑ Decoder Clock
❑ Genlock

– Use this menu to sync with the incoming signal. The Genlock menu enables
two radio buttons:
•Analog – Analog genlocking supports PAL B/G and NTSC. The main output must be
configured to PAL B/G or NTSC. When you use an analog clock source you can
configure the following:
· 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.
• 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).
You must select either Analog or Digital. The default is Digital.
