VIDEO INPUT
One HD or SD input with reclocking
270Mb/s or 1.5Gb/s serial compliant to EBU 3267-E, SMPTE 259M and SMPTE 292M
HD cable equalisation up to 140m with Belden 1694 or equivalent (approx. 100m with Belden 8281). SD cable equalisation >250m Belden 8281 or equivalent
Input return loss: -15dB for 50MHz to 1.5GHz

VIDEO OUTPUTS
Two equalised and reclocked loop-throughs of the HD or SD input and three configurable video outputs using RM34 frame rear module, or one loop-through of the HD or SD input, one dedicated SDI output and three configurable video outputs with RM45 rear module

Differential gain: <2% typ
Differential phase: +/- 1 degree typ.

PICTURE PROCESSING WHEN DOWN CONVERTING
Sophisticated two dimensional filtering gets broadcast results and avoids the complication of looking at multiple fields or movement detection, resulting in reliable, artefact-free conversion with broadcast filter quality
When down converting the performance can be optimised by choosing one of four alternative filter characteristics (sharpest, sharp, soft, softest)
When the input is SD the board processing is bypassed, so that the signal is passed without degradation

HD TO SD ASPECT RATIO CONVERSION
16:9 Anamorphic (for 16:9 SD systems) and either 16:9 to 4:3 Letterbox or 16:9 to 4:3 Full Screen with centre cut (for 4:3 SD systems)

FIXED VIDEO DELAY
There are three video delay settings available:
‘minimum’ – the video processing delay. With an HD input the delay is 16 SD lines (Anamorphic or Full Screen) or 52 SD lines (Letterbox). With an SD input the delay is 3.8us
‘fixed’ (52 SD lines) – this allows the aspect ratio to be changed live on air without any picture disturbance, for example
‘frame’ – can be used to match a variety of equipment or to connect with equipment that has no delay
