1. Implementation of a Hybrid Analog/Digital Video Management System City of San Jose, CA Kenneth Salvail, P.E. ITE District 6 Annual Meeting June 2006, Honolulu Hawaii

2. Implementation of a Hybrid Analog/Digital Video Management System 2 Topics  The Beginning  Analog Video Sharing Phase I  Analog Video Sharing Phase II  Digital Video Sharing  Hybrid Implementation  Considerations  Resources

3. Implementation of a Hybrid Analog/Digital Video Management System 3 The Beginning 1991 - San Jose Motorist Information System  The New Arena  Improve Travel Experience  Support Economic Vitality of Downtown  18 – PTZ Cameras  7 Miles - MM/SM Fiber  VICON/COHU Switcher

4. Implementation of a Hybrid Analog/Digital Video Management System 4 Analog Video Sharing Phase I 1994 - Silicon Valley Smart Corridor  The Growing Silicon Valley  Improve Day-to-Day Commute Travel Experience  Minimize Delay Impacts of Incidents & Events  83 – Fixed & PTZ Cameras  37 Miles - SM Fiber  2 – Additional Pelco Switchers

5. Implementation of a Hybrid Analog/Digital Video Management System 5 Analog Video Sharing Phase II 2001 - Silicon-Valley ITS Program (SV-ITS)  Install Common Pelco Analog Switcher System  4 – Additional Pelco Switchers  450 – Fixed & PTZ Cameras  70 Miles - SM Fiber  Expansion of Program to Include more TMC’s  Eliminate Multiple Control Units

6. Implementation of a Hybrid Analog/Digital Video Management System 6 Digital Video Sharing 2005 - Integration with Homeland Security & Maximize use of Fiber  Share Video Between State DOT & Other Local TMC’s  Meet Public Safety Needs  Allow Executive Staff Access  Facilitate Access by Remote Operators  Use Fiber Efficiently

7. Implementation of a Hybrid Analog/Digital Video Management System 7 Hybrid Implementation 2006 - 360 Surveillance Pilot  Encoding/Decoding Analog Video  IP Network for Transport  Management Server  Client Workstation  Maintain existing Analog Investments  Implement one Command & Control Interface for both Analog & Digital Video

8. Implementation of a Hybrid Analog/Digital Video Management System 8 Considerations  Hybrid Systems that are not so Hybrid Distribution vs. Command & Control Motion JPEG & Windows Media® Server Based MPEG 4 a decoding standard, with varying image quality Establish resolution and fps to simplify selection  MPEG Standards  Encoder/Decoder Compatibility Issues  Software Decoding Issues  PC Issues  IP Multicasting  IP Network Management  Field Ethernet Devices Use one manufacturers’ encoder & decoder Vary in optimization Hardware issues Significant processing power Video card requirements Viewed concurrently by multiple users Need to support IGMP across the IP network Capacity, design, and management needs Partner with IT staff early Field hardened Consider redundant path
