Avitecture Case Study: Sheldon Hall, Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland

The Challenge

The Johns Hopkins University Bloomberg School of Public Health is the first institution of its kind worldwide and the largest school of public health in the world.

The Johns Hopkins Bloomberg School of Public Health is dedicated to the improvement of health through discovery, dissemination, and translation of knowledge and the education of a diverse global community of research scientists and public health professionals.

Sheldon Hall, a large lecture hall at the renowned Bloomberg School of Public Health, had aging AV technology incapable of meeting the School’s requirements and in need of an upgrade to a digital platform. Avitecture was engaged to perform a full technology refresh. The AV systems accommodate basic presentation capabilities, recording, streaming and video production. Because the School’s AV staff required both manual and automatic room control, Avitecture provided full operator surfaces for both audio and video operation. The site’s high fit and finish demanded great care as the new technology was installed.

The Avitecture Solution

An NEC 7,500-lumen projector in the control room at the rear of the hall provides bright, high-resolution images. A Crestron Digital Media Matrix switch offers full video routing capability of presentation sources. Three Sony PTZ cameras capture in-room action for recording or streaming. A Biamp digital signal processor teamed with a Behringer digital mixing console allows for fully automatic or fully manual audio control. All video production is centered around the Newtek TriCaster. A fully integrated Crestron control system with easy-to-use custom touch panels allows both operators and users to manage functions.

A Crestron Digital Media switching system presentation matrix accepts both digital and analog inputs and presents all signals in digital format to displays. A lectern-mounted transmitter accepts signals from a dedicated lectern PC and from lectern laptops outputting either VGA, DVI-I or HDMI signal types. The lectern’s interactive display has full touch control and annotation over the dedicated lectern PC and serves as a preview monitor of the lectern PC. Laptops rely on the built-in laptop monitor for the presenter’s preview. The separate notes mode in PowerPoint allows the local monitor to display presenter notes that the room audience will not see.

Three new high definition pan-tilt-zoom robotic cameras link directly to a NewTech TriCaster 460 which has two production-grade video monitors and can switch and control the cameras. Two outputs from the presentation switch will be made available as a TriCaster input. The TriCaster has an external one terabyte hard-drive for video storage.

The Success Story

Avitecture’s AV-IT system in Sheldon Hall helps to enable faculty, students, and staff to fulfill the the Bloomberg School’s mission to advance research, education and practice to create solutions to public health problems around the world.
