Established in 1872, Boston University School of Law is a top-tier program with a faculty recognized nationally for its exceptional teaching and preeminent scholarship. In a move to provide its students with a cutting-edge learning experience, the university built a new 93,000-square-foot, five-story addition to its 18-story Law Tower, and completed a full-scale renovation of the original structure. Each of the new Sumner M. Redstone Building’s classrooms, practice courtrooms, and seminar rooms is equipped with AV technology to enable webcasting for remote learning and record-and-playback capabilities. Audio for the system is centered on Biamp Systems’ award-winning Tesira® digital signal processor (DSP), which provides pristine audio quality and the flexibility of audio video bridging (AVB/TSN) technology
Recognizing the importance of technology in the classroom, Boston University School of Law looked to provide students with a state-of-the-art educational experience. To achieve this, the university built the new Sumner M. Redstone Building in 2013. Located at the base of the Charles River Campus’ Law Tower, the building was intended to provide a new entrance to the law school and house most of its classrooms, and its practice courtrooms and seminar rooms. Each space would be outfitted with the latest AV technology to enable webcasting for remote learning, and would include record-and playback capabilities to help students sharpen their presentation skills in the courtroom. In a second phase of the project, the university’s Law Tower itself would be completely renovated, with its classrooms, courtrooms, and interview rooms receiving high-tech upgrades.
To realize Boston University’s vision, system integrator HB Communications installed a building-wide AV solution built around Crestron’s DigitalMedia™ and control products for AV switching, control, and monitoring; the Echo360 Active Learning Platform for recording and webcasting; with audio capabilities provided by Biamp’s Tesira platform. Tesira provides extensive audio processing; including signal routing and mixing, equalization, filtering, dynamics, and delay; as well as control, monitoring, and diagnostic tools. In addition, Tesira offers highly flexible and scalable networking capabilities by utilizing AVB/TSN. “When we were awarded this project, one of the first things we recommended was an upgrade from the older DSP that was originally specified to Biamp’s Tesira,” said Michael Dodge, senior systems design engineer at HB Communications. “For an AV system of this magnitude, we wanted to utilize the latest and most advanced technology. We’ve worked with Biamp for years and knew that Tesira would deliver impeccable audio quality. Plus, its ability to run AVB/ TSN over fiber was a crucial feature as the scope of the project expanded.”
Each of the 18 classrooms, three courtrooms, and numerous seminar rooms is equipped with Echo360 technologies and a Crestron DigitalMedia matrix switcher, allowing instructors to capture their lessons and make them available for students via their mobile devices. Audio and video signals can be sent to a control room, where AV operators at four workstations monitor and record classes and facilitate video conferencing capabilities. The control room headend features four Cisco Codecs for live remote teaching and video conferencing, an additional Echo360 recording device, a 128×128 Crestron DigitalMedia matrix switcher, and a 128×128 Kramer HD-SDI switcher. Initially, analog audio signals were being distributed to and from the control room over fiber, tying into a 128×128 Kramer audio switcher in the headend; this audio switcher was nearly full by the end of the building’s installation. When the renovation of the Law Tower began, many rooms were not originally intended to connect to the control room for monitoring and recording capabilities. However, the scope of the project expanded, resulting in the need to equip them with this functionality. With the originally specified switchers full, the decision was made increase the capacity of the Crestron DigitalMedia and Kramer HD-SDI switchers and to take advantage of Tesira’s extensive AVB/TSN channel count capabilities.
