Description
SDI IN
A 75 W BNC connector provides a serial digital video input
to the unit. This input is terminated in 75 W.
A 75 W BNC connector provides an HD serial digital video
input to the unit. This input is terminated in 75 W.
A 75 W BNC connector provides a high quality analogue
video input to the unit.
Optional - Studio Black and Burst should be fed to the
75 W BNC connector (H SYNC). This genlocks the
Encoder to the Studio system. This method may be
required with some audio formats, or for locking
Encoders to an evolution 5000 Multiplexer.
The 15-way, D-type male connector is used in different
ways according to the audio input and the encoding
configuration selected.
The connector provides two stereo pairs which may be
independently configured as either analogue or digital.
The left channel is used to input digital audio.
The Encoder is supplied with a break-out cable which
plugs into this connector, and provides a more
convenient means of connecting the audio signals via
five connectors. There are four XLR female connectors,
with the fifth cable being a BNC which provides an
AES/EBU 75 W digital reference output. This is for when
the unit is connected to an external Dolby Digital
Encoder.

An 8-way, RJ-45 connector provides a 10BaseT Ethernet
interface for communications with the TDC/MEM for
control and monitoring. The Encoder has a single
switched Ethernet channel. Ethernet#1 is selected as
default at power-up. If a carrier is not detected on
Ethernet#1 then the input switches to Ethernet#2. This
gives a redundant Ethernet control via two hubs.
RS-232/RS-485
Control
A 9-way, D-type male connector provides an
RS-232/RS-485 port for remote control of the Encoder.
This connector is wired as a DTE.

data. The options are; video line 21, video line 21 and line 284,
SMPTE 333M and SMPTE 334.
CC Format – select the required closed caption format, the default
is ATSC, and this is the required setting for EIA-708B compliant
closed captions.
SMPTE 333M Port – if the closed caption source has been set to
SMPTE 333M, then the Encoder’s RS-232 port through which the
data is to be input must be selected.
SMPTE 334 CC can be extracted from the HD-SDI.
For more details regarding setting up the Encoder’s closed caption
options see the Reference Guide.

Set the Audio Options
The standard Encoder can process two stereo pairs, but up to four can
be processed with the addition of audio option cards. All the audio
inputs are configured in a similar manner.
Navigate to the Audio Menu. Select the following options:
>
>
>
22
Source Option - select the audio source. This can be an analogue
or a digital input, or can be de-embedded from the SDI input. If the
audio source is embedded in the SDI (HD or SD) then the audio
DID must be set. Entering 1024 for the DID causes the default DID
for the selected group to be used.
Coding Standard Option - Select the coding standard, e.g.
MPEG Layer 2, Dolby Digital (AC-3) etc.
Bit-rate Option - select the required audio bit-rate.

Set the Data Options
Navigate to the Data Menu. If serial data, either RS-232 or RS-422, is to
be encoded then configure the input source and bit-rates.
4.9
Set the Output Options
The Output Menu allows the output of the Encoder to be selected. If the
modulator output is to be used then the Output Format should be set to
Sat. Modulator.
The Satellite Modulator Menu is then available to allow all the
modulator parameters to be configured.
4.10
Configuring Option Cards
For information regarding configuring any option cards that may be
fitted to the Encoder refer to the Reference Guide.
4.11
Satellite Modulator Control
A major advantage of having the satellite modulator integrated into the
Encoder is that the Encoder bit-rate can be automatically linked to the
satellite modulator modulation type, symbol rate and FEC rate.
Changing any one of these parameters causes the others to be
automatically updated.
4.11.1
Initial State of the Modulator
Following power-up the Modulator is configured into a safe state such
that:
>
>
>
The Modulator output is off.
Modulation is switched on.
The output power is set to the ‘Low’ setting.
The exception to this is if ‘Power Dip Recovery’ (in the Setup/General
Menu) has been enabled, and the power interruption was less than
eight seconds. In this case the unit will power up in the same state as
when the power failed.

The Ops Menu
The most frequently performed operation on a DSNG Encoder is
configuring the Modulator, switching the output on and off, and
controlling the output power.
The Ops Menu is intended to allow the user to quickly configure the
Modulator. The following parameters can be controlled via the Ops
Menu:
>
>
>
>
>
>
>
Output – On/off
Modulation – On/off
Output Power – Preset Low / Preset High
FEC Rate
Bit-rate
Symbol Rate
Frequency
Full control of all satellite modulator parameters is provided via the
Satellite Modulator Menu.
4.12
Configuring the Encoder for Minimum Bit-rate
The following parameters can be configured to minimise the video bitrate required for a given picture quality:
>
>
>
24
Compression Mode - the Compression Mode option is found in
the Video Encoder Menu. For minimum bit-rate this should be set
to standard.
Video Bandwidth - the Video Bandwidth option is found in the
Video Source Menu. To minimise the video bit-rate this should be
set to medium, or better still soft. However, this does effect the
sharpness of the pictures.
Noise Reduction - if the noise reduction option has been
purchased, then there will be a Noise Reduction option in the
Video Source Menu. The higher the level of noise reduction set,
the lower the video bit-rate, but the sharpness of the pictures will
be reduced.
Voyager E5784 and E5788 HD DSNG Encoder
NOTE
From SV 3.6.0, three new noise reduction levels have been added
when in SD mode. Please refer to the Reference Guide
>
>
>
Video Resolution - the Resolution option is found in the Video
Encoder Menu. Selecting a lower resolution will reduce the video
bit-rate, but will reduce the amount of detail in the picture.
GOP Structure - the GOP Structure option is found in the Video
Encoder Menu.
A new option, “Adaptive GOP”, has been added in SV 3.6.0. Please
refer to the Reference Guide. This option has always been available
in HD mode.
Long GOP - if the performance upgrade option has been
purchased, in the Video Encoder Menu there will be a Long GOP
which, if set to On, allows GOPs of greater than 0.5 seconds
duration to be selected. Setting a longer GOP may allow the video
bit-rate to be reduced, but at the cost of a longer time to acquire
the service. Also, if a very long GOP is used, the build-up of noise
up to the next I frame may become noticeable.
