Video Server for Subway Systems

Optelecom-NKF announced that it is deploying its S-44 video server, a recently introduced four channel video codec, as part of three major subway system projects now underway around the world. The largest installation is for the new rail line, Line 10, of the Beijing Metro System (BMS) in China and will support the transport and recording of more than 1,000 video signals. This is the third major contract award for the company from BMS. The other two strategic project wins are subway security systems for major cities in France and Spain. The video servers design combines four Texas Instrument DSPs on a single board. Each DSP can simultaneously transmit two MPEG-2/4 video streams and one Motion JPEG stream, with all of them simultaneously running at full D1 resolution. This capability to triple stream makes each channel available for simultaneous recording, live viewing, and screen capture.
