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
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

User’s Manual Installation • 5
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.
