PBS station KLCS has installed a Spectrum media server system from Omneon Video Networks to stream video to Los Angeles area public school classrooms.
The Omneon SPECTRUM systems allow facilities to add or expand I/O ports, bandwidth, capacity, and redundancy in granular increments, either simultaneously or independently, without interrupting system operation.
KLCS is integrating a 28-channel Spectrum server within a comprehensive digital content distribution system that provides near-video-on-demand (NVOD), streaming specialty channels, and other video and data content to the desktops of nearly one million students and teachers at Los Angeles Unified School District (LAUSD) campuses.
From the start of the school day until 4 p.m., KLCS will broadcast its main over-the-air DTV channel while delivering four to 10 streaming specialty channels directly to students' and teachers' desktops. Then from 4 p.m. to 8 p.m., the facility will shift from streaming channels to four traditional over-the-air broadcast channels, delivered through the cable system.
From 8 p.m. until 11 p.m., KLCS will offer a traditional DTV channel plus an HD channel, and then from 11 p.m. to 8 a.m. will shift to a regular DTV channel and a heavy data push for delivery of near-video-on-demand to the LAUSD campuses.
Teachers will be able to browse the entire contents of the KLCS and LAUSD media library, which includes not only video and audio, but also PowerPoint presentations, lesson plans, and other resources that will be searchable by grade level, subject matter, and state and federal standards. After previewing available material as low-res thumbnails on the WAN/LAN, teachers can request digital content for overnight datacast to the school server, where it is accessible for playout at any time.
