The University of Southern California (USC) in Los Angeles has deployed a new AV network, with Audinate Dante at its core, to more than 248 learning environments that will be foundational for a new hybrid distance/on-campus educational program the school will roll out this fall.
According to Joe Way, USC director of learning environments, the new network and systems enable faculty to simultaneously give lectures on campus, on-stream and also archive for future use. He adds that the system also facilitates classroom overflow — a result of classroom occupancy levels being dropped by up to 70 percent to accommodate social distancing. In this scenario, the faculty-member will be present in a classroom with a small group of students with additional small groups participating in the same lecture from adjacent rooms. The overflow rooms are equipped with cameras, microphones, displays/projectors, and networked sound systems to facilitate interaction.
The system also supports situations where the faculty member is uncomfortable or unable to be on-campus. In this instance, the faculty-member will present from home to students in classrooms and those attending remotely.
“The system needs to be flexible to change at any time,” Way says, acknowledging the dynamic nature of the pandemic. “We are moving to all-network-based AV that will allow us to transmit any signal to any location. Dante is critical in our ability to lecture-capture and microphone-share.”
Way and his team developed a templated approach that can be modified to facilitate varying workflows depending on the subject, department and lecturer-preferences. The core of the system, however, is a Crestron Flex UC Engine (the B140-Z or C160-Z, where Z stands for Zoom). These allow users to take a Zoom Virtual Room and make it live – using all NVX352s to encode and decode Dante.
Dante-enabled Shure networked mics – either MXA 910s or 710s – are used for lecture and student capture. Dante AVIO units are also widely used as encoders with some handheld mics and as output when the team needs to zone the room and mute the loudspeakers near microphones.
Dante Domain Manager network management software enables user authentication, role-based security, and audit capabilities for networks while allowing seamless expansion of systems over any network infrastructure. Way said the flexibility of the system is key, noting he expects to manage up to 1,100 nodes of Dante when the integration is complete.
“It’s critical that our system be as cloud-based and software-based as possible,” Way explains. “By using Dante Domain Manager we’re able to ensure we have complete observability, control and security across the network. And we’re able to utilize it both with the scheduling system we have and with individual instructor preferences. For the most part, faculty will be able to walk in at their scheduled time and the room will be ready for the way they want to teach. With things like Dante’s audio routing at our fingertips, we can set it all up ahead of time.”
For students who are on-campus but constrained by isolation requirements, AV-over-IP provides quality access to lectures and content directly over the school network. For those who are taking classes off-campus, AV-over-IP helps school IT to implement streaming services, eliminating unnecessary hardware and complexity so that students can get to the content they need wherever they are.
Audinate senior vice president of marketing and product management Joshua Rush notes, “Elite institutions like USC have earned a reputation for excellence based on the quality of the education traditionally delivered in campus lecture halls. Now, as they seek deliver the same high-quality educational experience remotely, the AV network is what connects the faculty and student body. A stronger network means a better connection, a better experience and better education.”
Way will join Rush on a webinar to discuss the changes forced on educators and how network technologies can facilitate pivots to remote, hybrid and online learning models. Go here to learn more and sign up for the webinar.
