Classes and programs originate from ten Stanford sites: two auditoriums in the Gates Computer Science Building; the Thornton case-study classroom; and six other studio/classrooms in the Engineering School; as well as from a videoconference facility.

Program signals from campus sites are monitored and switched by an 80-input, 80-output switcher to transmitters, two-way video systems, satellite uplinks and recorders in Master Control area. Classes are mastered on DVD and duplicated to DVD and VHS tape for distribution. Return-video and audio signals from distant sites are received and routed to appropriate studio/classrooms.

Uplink services to any site in the world are available through satellite connections. SITN also has C and Ku-band downlink receivers to capture satellite-delivered programs. Direct full-bandwidth digital video on telco fiber circuits can also be transmitted through a 45Mb/s broadcast-quality video fiber-optics line into the Pacific Bell digital hub in San Francisco. From there video may be routed through satellite up-links and fiber lines to broadcast networks and stations throughout the U.S.

Four microwave channels are used for broadcasting Stanford classes throughout the San Francisco Bay Area, while a fifth channel is used for special events and to connect with satellite uplink systems.

Two-way video systems are available to distribute programs to corporate and university sites and to provide SCPD/SITN customers with videoconferencing services.
