| 摘要： | The California Department of Transportation, Caltrans, District 11 has deployed a unique, first of its kind, video distribution system in the San Diego region. This system is a Metropolitan Area Network (MAN) using a fiber optic backbone employing Asynchronous Transfer Mode (ATM) technology. This system carries a diverse range of services such as Internet Protocol (IP) and traditional telephone technologies. Whereas the traditional CCTV video system uses point-to-point high bandwidth analog video with analog switch technology and FM multiplexing, the San Diego system utilizes an all-digital video technology centered on the use of network protocols. This network is characterized by several distinct uses of technology. These include its ability to route video using standard networking protocols and to provide additional services for command and control of the roadside video equipment. Network management and remote software configuration is accomplished though a stand-alone management system. The video system establishes video paths between field-deployed cameras and the Caltrans Transportation Management Center (TMC) through creative use of remote access software. Command and control are accomplished through innovative utilization of a distributed digital network with tie-ins to the legacy infrastructure. |
