Your Technology Divisions Division 27 – AV Technology Division 28 –Life Safety Division 29 –Other (TV Studio, Video Over IP…) Bid Your Divisions as Prime – DO NOT BID THROUGH ELECTRICAL – Electrical is Division 26 Require Performance Bond of Prime Bidder Do NOT let Your Technology Divisions bid through Electrical Contractor (Div 26) Saves Money and LOTS of Headaches!

3. Emerging Presentation Technologies & Trends in Education Analog Sunset – VGA and Analog connectivity eliminated on current devices – HDMI (High Bandwidth Digital Multi-Media Interface – HDCP (High Bandwidth Digital Copy Write Protection) – Duplicate Protection AND Multi-Screen Protection

4. HDMI Video 7.1 audio HDCP EDID CEC HDMI / DVI / DisplayPort DVI Video ------ HDCP * EDID ------ DisplayPort Video 7.1 audio HDCP EDID ------ * Optional and not supported on most DVI extenders

5. What is Driving the Future of AV? CONTENT – Where does it come from? – User computers – Video playback devices Cable feed Blu-ray and DVD disc players Video Teleconferencing CODECs – Cameras 5

6. Computer Evolution PC Manufacturers (and Apple) want two things: – Lower cost – Small form factor RGBHV is expensive and big Manufacturers are moving towards DisplayPort / Mini DisplayPort 6

7. Video Playback Device Evolution Content providers want one thing: control over their content HDCP is the industry standard HDCP requires a digital video format (i.e. HDMI, DVI, DP) 7

8. Say “Goodbye” to analog  Content providers have embraced HDCP and manufacturers have embraced DisplayPort and HDMI  Content provider support and set-top boxes  MPAA (Motion Picture Association of America) is petitioning the FCC to block movies from being transmitted via analog outputs  Feature support  1080p and Deep Color are only supported by HDMI formats
