Crystal Vision Introduction
1 Introduction
TANDEM10-VF provides a versatile solution for audio embedding and de-embedding for use
with Vision rack frames from Crystal Vision. It has a single SDI video path with a de-
embedder and an embedder which allow the extraction and insertion of up to 16 channels
(four groups) of audio.
Embedded audio signals can be extracted and output as analogue or AES, then resampled
and re-embedded into the video signal in the same or different channel position with user-
controlled gain and delay. Additionally, external analogue and AES audio inputs can be
embedded into the video signal in any channel position.
There are two slots for optional analogue and digital I/O piggybacks of which there are three
types: 3G-AIP2, 3G-AOP2 and DIOP4. The 3G-AIP2 piggyback has four analogue inputs; 3G-
AOP2 has four analogue outputs; DIOP4 has four stereo AES pairs – each pair can be
individually configured as an input or output. Any type of piggyback can be fitted into any of
the two slots to provide the desired mixture of analogue and AES, inputs and outputs.
The main features are as follows:
Use with any source:works with 3Gb/s, HD and SD.
Supports the following video standards: 625, 525, 720p50, 720p59.94, 1080i50,
1080i59.94, 1080p50, 1080p59.94, 1080psf23.98, 1080psf24.
Versatile audio: will de-embed and embed up to four audio groups and input or
output up to eight external AES stereo pairs or four analogue stereo pairs which can
be fully shuffled with the powerful 32 x 16 audio routers.
Optimise the video: video proc-amp allows adjustment of lift and gain in RGB and
YUV domain. TANDEM10-VF features a switchable 0-10 frame video delay – useful
for matching Dolby E or other audio processing delays.
Optimise the audio: each channel has individual gain control and stereo to mono
conversion. The audio level can be increased or decreased to match the rest of the
system: each mono audio channel offers individual gain control, adjustable between
+18dB and -18dB in 0.1dB steps. Audio channels can be muted and stereo pairs
converted to mono. PCM Audio channels can be delayed with respect to the video by
a fixed amount of up to 400mS.
Control of TANDEM10-VF is most easily achieved by Crystal Vision’s VisionWeb PC
software. Control can additionally be from an active front panel on the Vision frame,
remote VisionPanel or SNMP.
Optical connectivity: send signals beyond the local equipment bay with the fibre
input and output options.
VANC blanking option.
Supports the following Vision Rear Modules: VR02, VR12 and VR13.
Compatible with ‘Vision’ frames from Crystal Vision.
Passes all timecode, AFD and subtitling information.

Crystal Vision Introduction
TANDEM10-VF functional block diagram
Block Diagram Description
SDI video is cable-equalised, re-clocked and passed through a de-embedder block where up
to 16 channels of audio are extracted. The video signal is then processed allowing for
adjustment of video gain, black level and independent RGB and YUV gains. This is followed
by up to ten video frames of delay before the video is then passed to the embedder block
where up to 16 audio channels are inserted.
De-embedded audio and external input audio are processed with resampling, delay and gain.
Dolby E encoded signals bypass this process. After processing, the audio is passed to two
independent 32 x 16 routers which feed both the optional plug-in output piggybacks and the
embedding block. In this way any of the 32 input audio channels sources can be output
externally or embedded.

Crystal Vision Hardware installation
2 Hardware installation
All of the links and potentiometers on the card are factory set and should NOT be adjusted.
TANDEM10-VF cards are intended for use only in the Crystal Vision ‘Vision’ frame range and
not in older style frames such as ‘Indigo’.
The card should be inserted and removed from the Vision frame by gently pushing or pulling
the metal ring at the bottom of the card, being careful to ensure the card is inside the guide
rails. Do not force the card if resistance is met as the card may not be correctly aligned with
the rear connectors. The white tab at the top of the board is a label only and should not be
pulled.
Ensure that the Vision frame has the correct rear module fitted. Only the VR02, VR12 and
VR13 rear modules offer the correct input/output functionality for this card.
2.1 Piggyback boards
The TANDEM10-VF card has two positions where one of three types of piggy-backed I/O
module can be plugged to enable analogue or digital input and output.
The three types of piggybacks are 3G-AIP2, 3G-AOP2 and DIOP4.

The I/O piggybacks plug onto the main board such that main board plugs PL6, PL5, PL12 and
PL4, PL3, PL11 align with piggyback sockets SK2, SK3, SK1. With the component side of the
module top-most, align the piggyback sockets carefully with the plugs and push firmly. Insert
the plastic rivets supplied with the fitting kit through the main board (holes ‘A’) from the
underside so they protrude through the piggyback board, then push the rivet peg firmly to
splay the end to lock the piggyback board in position. Note: The position that the
piggyback is fitted determines the function of the rear module connectors. See Rear
modules and signal I/O for more information.

4 Control and Status monitoring
TANDEM10-VF status and controls can be accessed most easily by ‘VisionWeb’ remote
control PC software but also by VisionPanel, the Vision frame’s front panel and SNMP.
4.1 Controlling cards via VisionWeb
Accessing the ‘Vision’ frame homepage with a PC browser via the Ethernet connector of a
frame will display a list of the cards fitted. (See ‘Vision’ frame User Manual for more details.)
Typical Vision frame home page
The example above shows a TANDEM10-VF card fitted in slot 1 and other Vision cards in

available space. See Menu Structure for a more detailed menu tree.
VisionWeb GUI controls are accessed by tabs at the bottom of the page: Status, Video,
Audio, Audio router and Presets, default, alarms. These tabs, when selected, offer menus
containing a number of controls. Some controls are simulated LEDs that are used to show
status, others are check boxes, buttons or sliders which change various TANDEM10-VF
settings.
What follows are VisionWeb menu screenshots with a description of each control’s function.
Note that VisionWeb adjusts the number and type of controls displayed to suit the piggybacks
fitted, so screen grabs may not correspond exactly to a user’s own configuration.
The description of the menus is in the order displayed in the VisionWeb GUI:
Video, Audio, Sub PCB type, Delay & output, RGB proc, YUV proc, VANC, Fibre enable,
DeEmbedded input, Discrete inputs, Audio gain, DeEmbedded input delay, Discrete

‘OVERLOAD’ or ‘HIGH’ may cause the receiver to saturate with
poor or no video output. In extreme cases the receiver may even
be damaged – consider using an optical attenuator or a longer
fibre cable.
‘TOO LOW’ or ‘LOW’ may be the result of dirty optical connectors
– if in doubt, clean. Excessive fibre cable runs will also cause
these warnings. Although transmission distances of up to 50km
is possible with single-mode fibre, this distance is dependent on
minimal attenuation from junctions etc. Multi-mode fibre
installations can expect considerably shorter transmission
distances. Single-mode fibre, or any single-mode components
should never be used downstream of multi-mode fibre.
