[QUOTE="Charles Harrigan, post: 14663, member: 23"] Re: Small venue video distribution Heres what i know about digital display encryption systems: HDCP is a content protection system that uses a twisted pair for the checking of a encryption key known as a handshake. HDCP is built in to the HDMI, DisplayPort and DVI systems, as well as some proposed display protocols. Since they are currently using a system based on component video, you don't have to worry about HDCP as there is no HDCP over component video. This is why stores use component video for their in store displays. You simply plug the display into the distribution amp and it works. Also if they required HDCP over component video, people with pre-HDMI televisions would be unable to see HD content on their televisions. If you used commercial tuners the output solely over HDMI you would have a maximum of 16 displays per tuner (that limit is determined by the HDCP protocol). I think you would only need a switcher/scaler that accepts s-video, component, and VGA input and outputs in either VGA or component video. You would then most likely need a distribution amp and/or a video balun system to get the signal to the displays. You could have input plates wherever the dj's set up and wherever you foresee people needing to display video content in the future. Do the current displays have VGA inputs? [/QUOTE]
