MECHANICAL:
Standard Crystal Vision modules 266mm x 100mm.
Weight (with two piggyback modules fitted):
250g. Power consumption: 11 Watts
VIDEO SDI INPUT:
2 channels SDI 270Mbit to EBU 3267-E
& SMPTE 259M. Cable equalisation >200m
Belden 8281 or equivalent. Auto 625/525 line
selection. Automatic de-embedding of SMPTE or
Sony format
VIDEO SDI OUTPUT:
2 channel SDI 270Mbit to EBU 3267-E
& SMPTE 259M. Audio is embedded to SMPTE
or Sony format. 2 outputs of each with suitable
rear connector
EMBEDDER TIMING PERFORMANCE:
Inter-channel: <1 clock cycle. Audio to video:
Min 160us for Sony data format AES audio input.
Min 1ms for analogue audio input. De-embedder
automatically handles asynchronous and synchronous
audio
MONITORING:
1 x miniature front mounted audio jack and switch
selects individual stereo audio analogue monitoring
on both embedder and de-embedder. Also available
on rear connector
EDH:
EDH insertion on embedder and EDH error and
rate of error checking for de-embedder
STATUS MONITORING:
Front card edge visual monitoring with alphanumeric
and LED indicators to indicate: PSU rails present
- LED, SDI inputs - alphanumeric display, AES
audio inputs - alphanumeric display, Audio silence
- alphanumeric display, Piggyback card types
- alphanumeric display
DIGITAL AUDIO DELAY:
Presetable and controllable via the card or
Crystal Vision's active remote control panel.
Each half of TANDEM has its own adjustable delay
up to 0.68 seconds max or - in TANDEM-200 only
- up to 1.36 in audio bridge mode
AUDIO PROTECTION IN DE-EMBEDDERS:
A variety of sophisticated techniques are employed
to protect and minimise the effects of cuts
to untimed and asynchronous SDI, SDI corruption
and TRS loss in the SDI signal. An AES/EBU reference
can be applied to maintain audio integrity (silence)
with loss of video.
