if enabled, the decoder will calculate and use the max video bitrate for
the current TransMuxRate setting.
When disabled, the decoder uses the VRT setting for the video bitrate.
Please see F.A.Q. for more detail. On = 1
Off = 0 *.ECMD VAF

Manual Bit Rate
(Mbs/sec)
rate at which bits are streamed ; only available if AutoFill is set to 'Off'.
Limitations:
In standard definition encoding mode. (input is composite video, or
SDI auto-detected at standard definition)
1000000 - 15000000 bits/sec.
In high definition encoding mode. (SDI input only and auto-detected
as 720p or 1080i)7000000 - 60000000 bits/sec.

GOP Type
Group of Pictures; GOP type as open or closed
An Open GOP uses referenced pictures from the previous GOP at the
current GOP boundary.
A Closed GOP starts with an I Frame and subsequent B Frames do
not rely on I or P frames from the previous GOP.
GOP is expressed as one command, i.e., *.ECMD GOP [type]

GOP Size
GOP Size is the distance between two full image frames (I-Frames) in
a GOP Structure.

SD Standard
select television system standards the packet will be encoded for-
NTSC or PAL video. This is only available if the incoming SDI feed is
standard definition, or if the input is Composite.
NTSC

PAL-M
PAL-N
Chromatype
chrominance (color information) of video component
420 mode applies to high definition or standard definition encoding.
422 mode applies only to standard definition encoding.
420 = 0 (high

422 = 1 (std

*.ECMD CHT
Aspect Ratio ratio of horizontal to vertical lines in the encoded image
4 x 3 = 0

AFD
Active Format Descriptor is data that can be sent in a MPEG video
stream that provides information about the aspect ratio and picture
characteristics within the stream. AFD compatible display or STB/IRD
is required. AFD is related to Aspect Ratio. Aspect Ratio defines pixel
aspect ratio as encoded. AFD is used by downstream decoding
devices to properly display pixel aspect ratio on displays with differing
aspect ratios.
