Capped VBR Target QP
When in CVBR mode, this sets the target Quantization Parameter of
the encoder. High QP will result in more compression at the expense
of quality. Low QP will result in higher bit-rate and better quality.
Aspect Ratio
Selects the aspect ratio to be signalled in the output video:
•
16x9
•
4x3
•
1x1
•
WSS or WSS (line 18) ( Encoder only)
•
Video Index 11/324 or Video Index 8/321 (Encoder only)
AFD
AFD codes has below options:
•
Pass through: AFD codes transparent from SDI input to Video
output stream.
•
Off: AFD codes are not passed from SDI input to video output
stream.
Reduced Delay Mode
Enabling this mode reduces the encoding delay.
Please note that enabling this feature will lead to less processing and
therefore could impact picture quality at lower bitrates.
WSS Blanking
Enables WSS Blanking on the encoded output (Encoder only)
VITC
This controls the translation of Video Inserted Time Code (VITC) from
VANC in the input to Video Elementary stream. VITC is used to
accurately time stamp video frames.
Picture In Picture
Enable PIP video. This will generate a new selectable service for use
on any of the output modules. Both share the same audio.
PIP Resolution
Sets the resolution of the PIP video.
PIP Video Bitrate
Sets the bit-rate of the PIP video. Range: 250kbps to 1Mbps
The CBR video bit-rate affects only the video PID. An IP output may still be a VBR
transport stream. Some IP receivers require that the IP output is set to CBR mode. This
can be set on the
Port Settings
tab of the output stream

ONFIGURATION
Audio encoding capabilities and capacity are restricted by hardware and licensing. Depending upon hardware
the encoders support one or more of the following audio encoding formats
•
MPEG-1 layer 2 encoding
•
AAC-LC, HE-AACv1 and HE-AACv2 encoding
