Description
The profile to set when an HD input is detected on the HD-
SDI input. Visible only if Input Detection is set to Auto
Detect and Configure. If this option is visible, the Video
Profile cannot be set manually.
Defines the horizontal and vertical resolution of the
encoded video. The available options depend on the
values set for Video Input Format and Video Profile.
Defines the bit rate to be used by the compressed video
component. If Bit Rate Tracking Mode is set to Maximize
Video for the Transport Stream that contains the video
component, and the Bit Rate Weighting of the component
is set to other than Fixed or Minimal, this field is read only.
Constant Bit Rate operation.
Reduced encode delay (typically 350ms) achieved by
removing pre-processing functions. Bit Rate, GOP
structure and GOP length impact the delay. The IP GOP
structure will give lowest delay, but with reduced quality.
Encode delay reduced further by removing frame-sync in
pre-processing. Bit Rate, GOP structure and GOP length
impact the delay. The IP GOP structure will give lowest
delay, but with reduced quality.
Available if the AVP/SWO/CE-x/Stripe license is enabled.
Provides sub 100ms end to end latency for H.264
operation when combined with the appropriate Ericsson
RX8200.
Available if the AVP/SWO/CE-x/Stripe license is enabled.
Allows MPEG-1 LayerII audio encode in Stripe Refresh
This increases the latency by 1 frame compared to Stripe
Refresh.
Provides a fixed latency (~650ms) across the full bit rate
range of the selected H.264 video profile.
Does not affect the video encoding but rather indicates
what the desired aspect ratio for the decoded picture (not
the pixel). If no other mechanism such as WSS in the VBI
is used, the video output image will use this aspect ratio.
Defines the nominal distance in steps of video frames
between two consecutive I frames in the encoded bit-
stream.
Sets the number of B frames between reference frames.
IBBBBBBBP can only be used for 720p video format
encoded with a H.264 video profile.
