Crystal Vision Introduction
1Introduction
TANDEM 310 provides a versatile solution for audio embedding and de-embedding. 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 re-
sampled 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.
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, 1080i 50, 1080i 59.94, 1080p 50, 1080p 59.94, 1080psf
23.98, 1080psf 24.
•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 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. Audio channels can be delayed by up to 400mS.
•Optimise the video: video proc-amp allows adjustment of video gain,
black level and independent RGB and YUV gains. TANDEM 310
includes the additional function of a switchable 0-10 frame video
delay - useful for matching Dolby E or other audio processing delays
•Control of TANDEM 310 is by Crystal Vision’s VisionWeb web
browser software. Control can additionally be from an active front
panel on the frame, remote panel or SNMP. Card edge control was
also available prior to 2018.
•Optical connectivity: send signals beyond the local equipment bay
with the fibre input and output options
•GPI control of configuration set-ups and status alarms.
•VANC blanking option.
•EDH insertion.
TANDEM 310 User Manual R1.45 04 July 2019

Crystal Vision Introduction
•Supports the following rear module connectors: RM47, RM49,
RM60, RM61, RM70 and RM74.
•Compatible with Crystal Vision standard frames available in 2U, 1U
and desk top box.
•Passes all timecode, AFD and subtitling information.
TANDEM 310 functional block diagram
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 frames of delay. The video is then passed
through the embedder block where up to 16 audio channels are inserted.
All input audio from both external (up to 16 channels via the optional plug-in input
piggyback) and de-embedded sources (16 channels) are passed to audio
processing blocks where gain and delay adjustments are made after re-sampling
The outputs of the audio processing block are inputs to two independent 32x16
routers which feed the optional plug-in output piggybacks and the embedding block.
In this way any of the 32 sources can be output or embedded.

Fitting the I/O piggybacks onto the main board
Example showing 3G-AIP2 and 3G-AOP2 piggybacks fitted
The I/O piggybacks plug onto the main board such that main board plugs J3, J4, J5
and J6, J7, J8 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 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.

Crystal Vision General Purpose Interface
4General Purpose Interface
4.1 Introduction
Each frame slot has up to six connections ‘a-f’ for GPI control and monitoring. These
connections are available at the rear of the frame on the 26-way D-Type remote connectors.
TANDEM 310 has four GPI inputs and two GPI outputs.
Each General Purpose Interface (GPI) input is fitted with a 6800Ω resistor connected to the
internal +5V and in the following table, this equates to logic ‘H’. With the GPI preset recall
lines set to ‘level’ mode and no connections (logic ‘HHHH’), preset 1 will be selected. With the
GPI preset recall lines set to ‘pulse’ mode, the GPI will be activated whenever a bit is pulled
low but no change to the preset selection will occur when all bits return to logic ‘HHHH’. Note
that preset 16 is not accessible in pulse mode.
Note: Because the GPI inputs are sampled in the vertical interval it is recommended that in
‘pulse’ mode, the GPI should be asserted at least 2mS before the start of vertical sync to
ensure stability and held active for at least 40mS.
See Presets for details of inverting the GPI preset logic.
Each General Purpose Interface output (GPO) has a 270Ω resistor in series with its output.
This allows for an external LED to be driven, connected to a DC voltage of +5V.
The GPI inputs can be programmed to automatically recall a previously saved preset
configuration. The 16 user preset configurations are selected using binary notation. The two
outputs can be programmed to assert themselves for a number of different alarm conditions.
