Crystal Vision Debuts Latest Embedded Audio and Down Conversion
Technology At IBC 2009

Source: Crystal Vision
Crystal Vision will be showing its new generation of embedders,
synchronisers, down converters and switches on Stand 2.B11
at IBC 2009.
This new range of uniquely-featured 3G HD products proves
that Crystal Vision is leading the way with its 3Gb/s technology,
with the competitive pricing making the products suitable
for use in 3G, HD and SD systems.
TANDEM 3G is the first single board solution providing
a combined embedder and de-embedder for four groups of audio.
Its additional ability to work with 3Gb/s, HD and SD sources
makes it an economic and flexible solution for a very wide
range of applications.
Featuring bi-directional digital audio inputs and outputs
on the board which can be configured in stereo pairs, it offers
nine different combinations for embedding and de-embedding
external audio. Typically used for embedding or de-embedding
eight AES channels, or for embedding four AES while de-embedding
four AES at the same time, such is the flexibility it could
also be used to embed three channels and de-embed five if
required. When routing the audio TANDEM 3G offers full shuffling
and overwriting of the mono channels between all four groups
thanks to the powerful 32 x 32 audio router.
An audio delay of 80ms will compensate for any video processing,
while any of the AES audio can be modified with stereo to
mono conversion and gain adjustments. It includes extensive
Dolby E handling, including Dolby E positioning and a switchable
one frame video delay to match Dolby E delays. TANDEM 3G is
ideal for applications requiring both embedding and de-embedding
at the same time, while for those that just need to embed
or de-embed there is no price premium to buy one device that
can be used as both an embedder or de-embedder as required.
SYNNER-E 3G will simplify system designs for those
working with 3Gb/s, HD or SD sources in AES or Dolby E environments.
With the ability to work with four groups of audio, this ultimate
device for all embedding, de-embedding and timing requirements
combines a video synchroniser, tracking audio delay, embedder,
de-embedder, audio processor and video proc-amp on one 100mm
x 266mm board, and includes special features for flexible
processing of Dolby E.
The acclaimed synchronising features include full horizontal
and vertical timing adjustment, cross-locking, three point
synchronising and fast locking after an upstream switch to
avoid picture disturbance. With bi-directional digital audio
inputs and outputs on the board, up to eight channels of external
AES or Dolby E can be embedded or de-embedded in any combination,
while flexible audio routing comes from a 32 x 32 router which
allows the shuffling and overwriting of any channels.
The special Dolby E features include the ability to synchronise
video which contains a mixture of Dolby E and standard AES
within the same audio group, while the video and standard
audio can both be delayed to compensate for Dolby E delays
and a selectable one field video delay can be used to correctly
align the Dolby E data with the video frame.
Crystal Vision will be unveiling two new versions of its popular
Q-Down down converter at IBC.
One of Crystal Vision's most successful products, Q-Down is
a broadcast down converter and distribution amplifier with
two major advantages: a unique level of image quality in its
price range (with its sophisticated two dimensional filtering)
and a short processing delay of just 16 lines which eliminates
the need to compensate audio signals for the video delay.
The flexible outputs available include reclocked loop-throughs
of the HD or SD input and three Standard Definition outputs
individually link selectable between analogue (composite,
Y/C, YUV and RGB) and digital, while Q-Down also deals with
any aspect ratio conversion requirements.
The first new version is Q-Down 3G, ideal for those working
with or planning 3G HD installations with its ability to down
convert or distribute 3Gb/s, HD and SD signals as well as
optional embedded audio handling. Also new is Q-Down Mini
– Crystal Vision's first minibox designed for attaching
directly to the back of SD monitors in space-challenged environments
with no spare rack space. This customer-requested product
was developed because the customer could find no alternative
standalone product with the same level of conversion quality
or short delay: this is the first time a full broadcast quality
down converter has been available in a minibox. Competitively
priced and available with a separate power supply, control
comes from DIP switches accessed from outside the box, from
GPIs and from links within the box.
Also on show at IBC will be Crystal Vision's 3G HD modular
switching range of products.
The first of these is the SW803 3G – an 8 x 3
crosspoint routing switch which works with 3Gb/s, HD and SDI
and which can route eight inputs to any of three outputs.
The SW803 3G is perfect as a secondary matrix for small studio
uses, and is particularly suited to any small routing applications
already using other Crystal Vision boards, such as providing
a selection of backgrounds for a chroma keyer. Housed in the
standard frames and with up to six SW803 3G fitting in 2U,
it saves valuable rack space compared to a stand-alone routing
switch.
The SW803 3G can switch in the vertical blanking interval
to avoid picture disturbance, with timing information provided
by either a Black & Burst or Tri-level syncs analogue
reference or by a digital reference generated from any of
the four main board inputs, while the flexible control options
include PC software or a dedicated 1U control panel.
The SW221 3G provides simple and affordable 2 x 2 switching
between two 3Gb/s, HD or SDI signals and is ideal for use
either as an emergency transmission switch to avoid broken
equipment or to manually bypass products requiring maintenance
on a 24 hour station. An automatic switch away from a faulty
source is triggered on loss of input, invalid video or invalid
format, while with manual switching there is the choice of
switching between the two feeds either immediately or in the
vertical blanking period to enable a cleaner switch. The SW221
3G reduces the need for separate distribution amplifiers by
providing two outputs of the first switched signal along with
one output of the second, and includes relay bypass protection
on power failure or board removal to provide an extra layer
of security.
The third routing switch is Smart Switch 3G, which
is ideal for securing the video output in systems that need
high reliability. It provides intelligent 2 x 2 switching
to a backup signal source by monitoring two 3Gb/s, HD or SDI
video inputs with up to four groups of embedded audio and
switching between the sources if a specified fault condition
arises, and also includes relay bypass protection.
Smart Switch 3G has been designed to extract information about
various parts of the video signal to decide which of the two
inputs is better, based on a user selection of which parameters
are significant. Any number of criteria can be selected from
a long list, including input present, input video standard,
video frozen, video black, various EDH errors (SD only), line
CRC error (HD formats only), audio group missing and silence
on a specific audio channel. Smart
Switch 3G will switch away from an error on the main input
only if the backup is free of that fault, while should the
main and standby inputs have different alarms set Smart Switch
3G will work to the most significant feature to decide which
input to select. Smart Switch 3G is most commonly used with
the Statesman PC software, where it can be set to either ignore
or create an alarm on any of the numerous features it can
measure.
Extensive demo areas on the stand will allow IBC visitors
to try out the new features for the Picturestore range, Crystal
Vision's area of speciality based on solid-state fast reading
and writing DRAM and permanent Flash picture storage.
The new features for the MultiLogo logo keyer and the Clip
N Key clip and sting store include versions with an 8 GB video
store, plus the addition of audio functionality and the ability
to lock the output to an analogue reference to ensure a correctly-timed,
uninterrupted output.
Crystal Vision now offers affordable sports action replay
of up to 60 seconds of HD video or 310 seconds of SD with
Playback 8G. Finally, for engineers who need to match any
very long delays in their system, ViViD HD-40 provides up
to 43 seconds of delay in HD and 238 seconds in SD.
