EX-SDI<br />
EX-SDI TECHNOLOGY<br />
The EX-SDI (Extended Serial Digital Interface)<br />
is a transmission method to overcome<br />
the transmission distance limitations<br />
of HD-SDI technology.<br />
The HD-SDI signal will be compressed to<br />
270Mb/s instead of up to 2.97Gb/s for an<br />
uncompressed Full HD HD-SDI signal.<br />
This compression is visually almost not<br />
noticable and is executed within less then<br />
100μs, so the advantages of HD-SDI will<br />
be kept up, while the limitation will be<br />
removed.<br />

With EX-SDI you can increase the transmission<br />
distance on an RG59 cable from<br />
100m for an Full HD signal, or <strong>16</strong>0m for an<br />
HD signal up to 330m with EX-SDI.<br />
With higher quality cable (for example<br />
RG11) you can reach more than 600m<br />
transmission distance instead of 200m.<br />
