MORE FIBRE FEATURES
THE FTX-L 3G is a new fibre optic transmitter designed to transmit 3Gb/s, HD or SD signals
over large distances in a robust, reliable and space-saving way and including two input loop-
throughs ideal for system checking or distributing input video.
With its two independent 3Gb/s, HD or SD inputs, the dual channel FTX-L 3G fits in the
standard frames and will save you both money and rack space by allowing up to 24 channels
in 2U. It meets the SMPTE 297-2006 short-haul specification, allowing operation with single-
mode and multi-mode fibre.
The FTX-L 3G includes two customer-requested input loop-throughs, which can be used to
distribute the input video to equipment such as a picture monitor, or alternatively for system
checking: if a signal path has a good input and a faulty output, you can use the spare output
to check each stage of the system without breaking any of the connections, and so work out
which cable or piece of equipment is broken.
The standard FTX-L 3G uses a wideband 1310nm laser, but Crystal Vision can alternatively
provide narrowband CWDM lasers on request – allowing you to get multiple signals through
one fibre by using a different wavelength of light for each signal.
Shipping now, the FTX-L 3G replaces the FTX 3G – bringing extra features at the same
competitive price. It is the perfect companion product to Crystal Vision’s FRX 3G fibre optic
receiver. Inputs and outputs are accessed using the RM55 frame rear module – conveniently
the same rear module used for the FRX 3G receiver.

EMBEDDING, DE-EMBEDDING
AND DOLBY DECODING
WELCOME to the July edition of our
“Vision On” newsletter.
We are delighted to announce the
launch of four new products in this
edition – plus our first venture into the
world of Dolby decoding with a very
neat solution. Read about our first
3Gb/s-capable embedder for analogue
(as well as digital) audio, an enhanced
fibre optic transmitter and two
synchronisers for those video-only
sources. You can find out even more
about these products at IBC in
September where we’ll be in our usual
spot on Stand 2.B11.
Plus find out which broadcaster
is using 130 of our up and down
converters and discover who else has
been buying our products from around
the globe.
CRYSTAL VISION has launched its most powerful
audio embedder/de-embedder yet.
TANDEM 310 is a combined embedder and
de-embedder for 3Gb/s, HD and SD sources
containing up to four groups of audio, with the
ability to embed and de-embed a mixture of
up to eight AES stereo pairs and four analogue
stereo pairs (or eight mono channels) at the
same time – while decoding Dolby E.
With TANDEM 310
Crystal Vision releases for
the first time a 3Gb/s-
capable product that can
embed and de-embed
analogue audio – making
the product ideal for
studios where micro-
phones make analogue
audio popular.
TANDEM 310 embeds
and de-embeds external
audio by fitting up to two audio piggybacks to
the main board. Three different piggybacks are
available. For analogue audio there’s the HD-
AIP2 for embedding two stereo pairs or four
mono channels and the HD-AOP2 for de-
embedding two stereo pairs or four mono
channels. For digital audio the new DIOP4
piggyback is used for embedding or de-
embedding four stereo pairs, with four bi-
directional AES ports available on each piggyback
and the engineer able to select whether to embed
or de-embed each channel independently.
By fitting two of these piggybacks TANDEM
310 can be configured as a two group analogue
audio embedder/de-embedder or a four group
AES embedder/de-embedder. Alternatively
analogue and digital piggybacks can be mixed
to create a hybrid system – ideal for those using
analogue microphones with digital audio mixers
in the studio.
TANDEM 310 can
also be fitted with a
DBE-D Dolby decoder,
allowing a Dolby signal
in the embedded
video input (or from
an input piggyback) to
be decoded and either
output as analogue
or AES audio or re-
embedded – find out
more in the DBE-D story!
TANDEM 310 can shuffle and overwrite audio
channels taken from the incoming video input,
input piggybacks and DBE-D Dolby E decoder.
TANDEM 310 is the first product to feature auto
configuration of the Statesman PC software
controls (including audio routers) according to
the piggyback and Dolby decoder options fitted
to the motherboard – meaning the engineer
gets to see just the controls relevant to them.
As well as featuring short minimum delays for
both the audio and video to help prevent system
lip-sync complications, TANDEM 310 makes it
easy to match all the signals – with an adjustable
audio delay of up to 400ms and ten frames of
video delay which can be used to match any big
system delays, such as those created by Dolby E
encoding and decoding or transcoding to AC3
and re-embedding.
The audio and video can both be optimised,
with audio gain adjustments, stereo to mono
conversion and a video proc-amp. TANDEM 310
can also easily be given integrated fibre input/
output connectivity by fitting the FIP fibre input
option, FOP fibre output option or FIO fibre
input and output option.
TANDEM 310 is the usual space-saving
100mm x 266mm module. Five different frame
rear modules are available (the RM47, RM49,
RM60, RM61 and RM70) allowing use with both
75 ohm and 110 ohm audio, with an RM46
additionally available if a DBE-D is fitted.
TANDEM 310 will be shipping in August.
THE FUTURE OF
DOLBY DECODING
THE DBE-D sees Crystal Vision’s first foray into
Dolby decoding.
The DBE-D Dolby decoder is a top board
which connects directly to the main board
through an expansion connector. Used initially
for the TANDEM 310 audio embedder/de-
embedder (see the TANDEM 310 story!), it will
also be used to add increased functionality to
future synchronising products.
The DBE-D allows a Dolby E signal to be
decoded and then either output as analogue or
AES audio (using the appropriate piggybacks)
or re-embedded into the output video. The
Dolby signal can come from the embedded
video input or from an external audio stream
which is input via a DIOP4 piggyback, with the
engineer able to select which Dolby E signal to
send to the decoder.
The DBE-D also includes a stereo down mix,
which mixes the multiple audio channels within
the 5.1 surround sound down to a single stereo
pair for easier monitoring.
The DBE-D will be shipping in August. It is
perfect for those embedded audio applications
where the audio within the Dolby E stream
needs to be processed in some way, or where
the Dolby E needs to be decoded before
transmission.
