I'm setting up a SmartGrid Demonstration Center which will be utilized to demonstrate our clients product and services to their respective clients.  They wil have various different display monitors located throughout the demonstration center, and they want to be able to distribute static and dynamic video to the various display enpoints.  Some display endpoints have traditional HDMI, Coax, and traditional AVI input.  The video content will be packaged by a third party vendor and the client would like to distribute the video content seemlessly to their various digital screens on demand.  Could you recommend what software and hardware would be needed to manage, and delivery the content to the various digital signage displays.
