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.
