Out with the Analog, In with the Digital Distance Learning Classroom Goes High Definition! - February 3rd, 2010

The Learning Technology Center is putting the final touches on the first major system overhaul of its Distance Learning Classroom (DLC) since its construction in 1998. Analog cameras, control systems, document camera, video monitors, and most other system components were replaced with high definition (HD) digital equipment during the semester break.

“A lot of the high definition equipment that we installed has just been introduced, and we are the first to purchase it. The DLC’s video and control systems are definitely state-of-the-art,” says Frank Escobedo, LTC Administrative Associate, who purchased all the equipment for the complex project.

A crisp, high definition signal originates with the room’s three remote-controllable HD cameras. New Crestron touch panels with all-new programming allow the user to easily control inputs to the rear projection screen and two auxiliary flat panel HD monitors, as well as room lighting and audio volume. A new disc player allows Blu-ray video to be viewed in the room. The DLC will also soon be able to offer webcasts and podcasts.

The DLC’s control room has also been transformed with digital equipment. Four small flat panel monitors allow DLC technician Craig Smith to view preview and program video, as well as codec and cable TV inputs. Says Craig, “We’ve been planning the upgrade of the DLC systems for several years now, so it’s great seeing it all finally come together.”

Along with Craig and Frank, Chris Yallalee, Ryan Baldwin, Ken Waters, and James Keys worked with Crestron Electronics and Troxell Communications to bring the project to fruition.

The work should wrap up shortly. The analog codec, which sends and receives teleconferencing video signals, will be replaced with a digital HD codec, and equipment to record the HD program for later viewing will also be added. The HD conversion will then be complete, allowing the DLC to continue to provide the best videoconferencing service possible for the College of Education.
