Operating instructions

Stream Output
Reflex
HD Vertical Blanking Interval/Ancillary Data Configuration
GOP Structure IP, IBP, IBBP, IBBBP Sets the number of B frames between reference frames
Scene Cut
Detection
On, Off
Configuration to minimise affects caused by scene
changes. An I-Frame will be inserted on scene
changes, changing GOP length.
Seamless Buffer
Delay
50 ms to 5 s Defines the video buffer delay
Min Seamless Bit
rate
Min bit rate for VBR operation
Lookahead Delay 360 ms to 1000 ms
The time between the lookahead encoder estimating
the required bit rate and the final encoder encoding
that piece of video.
Delay Status Only This reports the actual video encoding delay.
Parameter Values Description
Embedded PCR On Off
Controls whether a PCR (Program Clock Reference)
should be included within the compressed video
component stream.
Copyright On Off
Controls the copyright flag within the elementary
stream header.
Original On Off
Controls the original flag within the elementary stream
header.
Parameter Values Description
Enable Reflex On, Off
This controls whether Reflex Statistical Multiplexing is
enables for the video output. THIS SHOULD NOT BE
SET VIA THE WEB INTERFACE, but should only be
controlled by nCC
Device Rx Counter Status only
This shows the number of Reflex messages received by
the unit. If Reflex is enabled this should be increasing.
Device Tx Counter Status only
This shows the number of Reflex messages transmitted
by the unit. If Reflex is enabled this should be
increasing.
Socket Rx Counter Status only
This shows the number of Reflex messages received by
the VCM. If Reflex is enabled this should be increasing.
Socket Tx Counter Status only
This shows the number of Reflex messages transmitted
by the VCM. If Reflex is enabled this should be
increasing.
VBI/ANC
Closed Captions
The source for Closed Captions data (off or SMPTE 334) encoded as part of
the Video Stream (only applicable when Video Frame Rate is 29.97 Hz)
Generic VANC Control
Generic ANC Extraction
Controls whether the ANC data (excluding audio) is extracted from the SDI
input and carried in the VBI component in accordance with SMPTE 2038.
