SDI Passthru

provides a re-clocked SDI loop for the
encoder

Off = 0
On = 1

*.ECMD SPT

Rate- Auto Fill

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
[state]

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] [structure]

CODEC

CODEC is the type of video
compression used during encode.

MPEG 2
MPEG4/AVC

*.ECMD VEN

Video Size-
Horizontal

horizontal pixel resolution.
Auto-detected for SDI signals.

varies by encode mode

*.ECMD HSI

Manual Bit Rate
(Mbs/sec)

rate at which bits are streamed ; only
available if AutoFill is set to 'Off'.

Standard Definition encoding mode:
(input is composite video, or SDI
auto-detected at standard definition)700kb
- 100mb bits/sec
High Definition encoding mode: (SDI
input only and auto-detected as 720p or
1080i)7000000 - 60000000 bits/sec

*.ECMD VRT

GOP Size

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

1-30

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
422 = 1

*.ECMD CHT

Video
Size- Vertical

vertical pixel resolution. Auto-detected
for SDI signals.

varies by encode mode

*. ECMD VSI

GOP Structure

Group of Pictures format; the order of
interframes and the various types of
picture frames that will be used.

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

*.ECMD VID

Video Loss

only available in standard definition encoding; sets unit to hold the frame
until video returns or drop the frame and stream if incoming video signal is
lost.

Stop = 0
Black = 1
