Implementation of a Hybrid Analog/Digital Video Management System 3 The Beginning 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

Implementation of a Hybrid Analog/Digital Video Management System 4 Analog Video Sharing Phase I 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

Implementation of a Hybrid Analog/Digital Video Management System 5 Analog Video Sharing Phase II 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

Implementation of a Hybrid Analog/Digital Video Management System 6 Digital Video Sharing 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

Implementation of a Hybrid Analog/Digital Video Management System 7 Hybrid Implementation 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

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
