PROBLEM: You have an HD video signal that needs to be sent from one side of a building to another with minimal latency and quality loss. Laying out your own cable is not an option.
SOLUTION: Almost all business buildings today have CAT5 wiring for computer networking. Using the Teradek product it is possible to route your signal long distances using the the local nework between your video source and video destination.
You will need to work with the networking contact of the building to obtain live network jacks at your source and destination. Ideally the route between source and destination would be a private VLAN, or routed through off network hubs / switches. Using the office LAN may result in poor performance depending on the network design and traffic load.
The Teradek is an advanced H.264 encoder / decoder pair. It will accept either HD-SDI or HDMI video (720p, 1080i). The encoder will need to be configured with an acceptable IP address. The decoder will need to be configured with an acceptable IP address and also the IP address of the encoder. On a 'dry run' networking pair you will need to manually define IP information. On a functioning network you may configure via DHCP. The source and destination network address must be on the same network, or 'pingable'.
The teradek decoder will output a signal as HD-SDI or HDMI depending on the model purchased. This can then be brought into your needed application.
Example of Use:
At O'Reilly's Velocity 2011 Conference this solution was used to route video from the Keynote Address to the EXPO hall floor. This included routing the signal through multiple patch panels in the venue. The routing covered a distance of several thousand feet. The advantages are that we utilized in place infrastructure to route video where it would only be possible otherwise through an expensive and unsightly cable drop otherwise.
