BitLink Professional HDTV Decoder
The BitLink Professional HDTV Decoder (hereinafter called the
BitLink Decoder) meets the highest standards in picture quality,
flexibility and reliability, for both HDTV and SDTV. The BitLink
platform affords cable, satellite and terrestrial operators, plus new
players, a cost effective and flexible way to transit to the DTV Market.
The BitLink Decoder supports extensive decoding and system modes
making it ideally suitable for use in ATSC/DVB contribution and
professional network monitoring applications.
User's Manual Overview • 1
Page 8
Video decoding formats cover interlaced and progressive HDTV
formats as well as SDTV for 60Hz. Both digital and analogue video
outputs are available.
The BitLink Decoder comprises of a 1RU rack-mounted, forced-air
cooled frame.
Modular Approach
The BitLink Decoder was designed with modularity as a key criteria.
This modularity facilitates easy adaptation to a number of different, and
in some cases not so obvious, decoding/DTV applications. The I/O
modules provide extensive choices in terms of transport stream
interfaces, e.g. 8/QPSK, ASI, analogue or digital video outputs, digital
and analogue audio outputs and video reference input. All transport
stream interfaces, except for the 8/QPSK demodulator, also provides
independent outputs that can be routed from any available input
module. In this way the "decoder" can be used for format conversions,
e.g. from QPSK to ASI.
General Features
MPEG-2 MP@HL and MP@ML
Transport stream input options include: ASI, QPSK
Support for up- and down-conversions
Up to two digital PCM and analogue audio pairs
Pass-through of Dolby Digital (AC-3)
Closed Caption support
Front panel, Web or Serial control

Do not operate this product from a power source that supplies
more or less than the voltage specified for the products.
Provide proper ventilation
User’s Manual Installation • 3
Page 10
To prevent product overheating, provide proper ventilation and
do not obstruct the ventilation areas on the units.
Do not operate with suspected failures
If you suspect there is damage to the products, have it
inspected by qualified service personnel. Do not attempt to
repair the failure even if you suspect it may be a minor
problem.
Packaging
Visual check
When you receive the BitLink Decoder, examine the package for
obvious signs of damage. The delivery should not be accepted if the
packaging is damaged.
Open the packaging carefully and check for any obvious product
damage incurred during shipping. If there is any damage please contact
your distributor immediately.
Unpacking
Check the equipment against the delivery/packing note when
unpacked.
Retain the packaging, as it is required for warranty shipments.
Don’t grasp the unit’s front panel when unpacking.
General Installation Instructions
WARNING!
These installation instructions are for use by trained personnel only. To
reduce risk of electric shock, refer servicing to qualified personnel only.
Site Requirements
An ambient temperature should be maintained between 10 deg C (45
deg F) and 40 deg C (104 deg F) at a relative humidity of 10-90% (noncondensing)
WARNING!
To avoid electric shock, never remove the unit’s lid. There are no user
serviceable parts inside. Refer servicing to qualified personnel. Failure to
comply may result in equipment damage and/or personal injury.
WARNING!
Always remove main cord from unit before removing the front panel or the I/O
modules.

Electrical power connection
WARNING!
The equipment must be grounded to avoid electrical shock. Failure to ground
the unit may cause equipment damage and/or personal injury. Particular
attention should be given to supply connections when connecting to power
strips rather then direct connections to branch circuits.

The BitLink Decoder can be mounted directly in a 19” rack, using the
supplied rack mounting hardware (for both front and rear side).
WARNING!
Do not put any extra weight on top of the BitLink Decoder when mounted in a
rack.
Connecting
Transport Stream Input
Ensure you have a valid transport stream on either the ASI or the RF
(demodulator) input.
Default (out of the box) setting is ASI 1.
Note! Coaxial cables for ASI inputs and outputs must be double-shielded.
Video Output
Use one of the video outputs and connect to your monitor.
Note! Coaxial cables for SDI outputs must be double-shielded.
Audio Output
Connect the audio output (if available) from the BitLink Decoder to an
audio amplifier or similar.
Default (out of the box) setting is decoded audio, available on both
analogue and digital outputs.
Power
After connecting TS, Video and Audio, power up the unit.
For detailed information on connectors, see Connections, page 33.

7. Connections
General
The BitLink Decoder has a wide range of input and output interface
modules available and can be configured in a number of different ways.
The following sections will describe the different modules and their
connectors.
ASI module
The ASI module provides dual ASI transport stream input and outputs.
Note! This module is optional.
ASI Out 1/2
DVB-ASI output, BNC 75 ohm (looped from input or any other TS
input module).
ASI In 1/2
DVB-ASI input, BNC 75 ohm.
Lock LEDs indicates when a valid transport stream is provided.
Note! Coaxial cables must be double-shielded.
User’s Manual Connections • 33
Page 40
8/QPSK Demodulator module (DEM)
The DEM module is an L-Band RF 8/QPSK, 16QAM demodulator
(950 – 2150 MHz) with two inputs.
Note! This module is optional.
8/QPSK In 1/2
2x F-type 75 ohm. These inputs can be routed to ASI outputs.
Note! If both inputs are connected to signals with the same frequency and
bitrate, the signal strength need to be reduced to -55 dBm, due to cross talk
of -25 dBm between inputs.
Digital Video Output module (DVO)
The Digital Video Output module (DVO) provides digital outputs
separately for both SDTV and HDTV. Note that only SDTV or HDTV
outputs are active at a time.
Note! This module is optional.
SD SDI Out 1/2
2x Serial digital SDTV output according to ITU-R BT.656.
HD SDI Out 1/2
2x Serial digital HDTV output according to SMPTE292M.
Note! Coaxial cables must be double-shielded.
Analogue Video Output module (AVO)
The Analogue Video Output module (AVO) provides analogue outputs
for both SDTV and HDTV. Note that only SDTV or HDTV outputs
are active at a time.
Note! This module is optional.
VGA
VGA HD output (RGBHV).
34 • Connections User's Manual
Page 41
Note! Only active for HDTV and if YPbPr is selected, the VGA output
does not have a valid signal.
R/Pr
Pr Colour difference signal or Red depending on the mode chosen in
the menu Output > Video > Analogue Format SDTV and HDTV
respectively.
G/Y/CVBS
Luminance or Green analogue output or Composite PAL/NTSC
output depending on the mode chosen.
B/Pb
Pb Colour difference signal or Blue depending on the mode chosen.
Video Reference Input module (GLK)
The Video Reference Input module can be used to lock the output
video to an external composite video reference as an alternative to the
PCR in the transport stream.
Note! This module is optional.
Video Ref
Composite video reference input with loop through according to ITU-R
Rec. BT.470-3. Needs to be terminated with 75 ohm.
Audio Output module (DAO)
The Audio Output module (DAO) provides 2 channels of both
analogue and digital audio.
Note! This module is optional.
Analogue Out
2 balanced stereo pairs (same as digital outputs) on 1x DB15.
See Appendix A for pin-out.
Note! Analogue audio is only available if the audio is decoded.
AES3 Out 1
48kHz unbalanced digital audio output (SMPTE276).
User’s Manual Connections • 35
Page 42
AES3 Out 2
48kHz unbalanced digital audio output (SMPTE276).
System Controller module (QMC)
The System Controller module (QMC) provides an external
remote/control interface.
RS232/422
The RS232 port is used for 3
rd
party control of the BitLink Decoder.
To obtain protocol information, see Serial Control, page 31.
See Appendix A for pin-out.
Ethernet
The Ethernet connection is used for the Web interface (see page 21)
and to upgrade with new software.
Alarms/Control
The Alarms/Control connector is reserved for Alarm relays output and
future implementation of GPI.
The QMC has three alarm relays, one for warning alarms, one for minor
alarms and one for major alarms. Each relay is connected to three pins
on the Alarms/Control port. The three pins are called “common”, “A”
and “B”. When an alarm occurs there will be a short-circuit between
“common” and “A”. When no alarm is active there will be a shortcircuit between “common” and “B”.
