Extron NAV Pro AVoIP Connects Researchers at Korea Institute for Advanced Study with Peers Worldwide
Once KIAS decision-makers saw how the NAV Pro AV over IP design scaled so easily to accommodate meeting spaces of various sizes, they almost immediately began planning for future phased expansions of their VTC capabilities to extend the reach of their knowledge sharing events.
Korea Institute for Advanced Study - KIAS - was founded in 1996 by the government of South Korea to promote research excellence in the basic sciences. KIAS is located on a 30-acre site in Seoul, where its members are provided with a research-friendly environment that fosters the advancement of learning and the discovery of new ideas in the fields of mathematics, physics, and computational sciences. The Institute is a destination for scientists from all over the world to conduct collaborative research. It hosts international meetings, seminars, workshops, and seasonal schools where participants exchange ideas across disciplines and disseminate research findings.
To further its collaboration goals, KIAS embarked on a project to equip its facility with a robust and professional VTC, video teleconferencing, capability to connect its collaboration sessions, meetings, and seminars to presentation spaces throughout the building and to scientists anywhere in the world. After conducting an initial survey of potential VTC system vendors, KIAS engaged its long-time AV supplier, Seoul-based pro AV integrator Neuroo Digitech, who arranged a design consultation at the Extron Regional Training & Support Center in Seoul. KIAS came away from that meeting impressed with Extron’s products and people and decided that a solution using Extron’s
KIAS required video teleconferencing connectivity between four meeting spaces within their main building, including a large 100-person lecture hall and three 30-person meeting rooms. These venues also needed VTC connectivity to overseas participants via the Internet. Neuroo Digitech completed the system design in one month, then proceeded with installation, which took 15 days. The inherent simplicity of distributing AV over the existing enterprise data network infrastructure made such a rapid design and install schedule possible.
Lecture Hall VTC System Includes Multiple AV Sources and Displays Connected Via NAV Pro Networking
Attendees at sessions held in the lecture hall watch 4K video on a projection screen and two 129” flat panel displays. AV sources available to presenters include a PC, three PTZ cameras with joystick control, and a VTC hardware codec. A ceiling array microphone captures room sound. Presenters speak into wireless microphones. All mic audio passes through a DSP audio conferencing processor and audio mixer to combine the various sound sources, perform echo cancellation, and apply other sound conditioning before delivery to ceiling speakers.
Content is streamed to remote audiences via the VTC hardware codec and through the Zoom unified communications platform.
A 1 Gbps Ethernet switch performs AV matrix switching to route AV signal sources to their destinations. The AV sources interface to the switch via six
Smaller Meeting Rooms Equipped with Scaled-Down Version of Lecture Hall VTC System
The VTC systems in the three 30-person meeting rooms share the same design as the 100-person lecture hall. The meeting room VTC systems are identical to the lecture hall VTC system, except that these smaller venues are equipped with one camera and one 55” flat panel display. This reduced the number of NAV Pro endpoints per room to four encoders and four decoders. KIAS decision-makers were delighted with how the design scaled so easily thanks to the versatility of NAV Pro AV over IP networking.
Intuitive Control of Presentation Materials and VTC Functions from the Podium
Presenters can advance their PowerPoint presentation slides, perform on-screen annotations, and control the VTC system without distraction, all from the podium. They select VTC modes and functions using clearly marked buttons on the podium’s
As they finalized the requirements for their video teleconferencing system, KIAS reached out to several AV system suppliers to explore options. Of all the suppliers KIAS approached, only Extron provided the level of support that KIAS felt their project deserved.
KIAS was impressed with the solid, actionable technical information available on Extron’s website, as well as the case studies on the website that chronicled user experiences with applications similar to theirs. KIAS’s comfort level with Extron was bolstered by the responsiveness and technical expertise of the people at Extron’s nearby Seoul Regional Training & Support Center.
Extron’s quotation was not the lowest bid, but KIAS recognized that the NAV AV over IP system was the most cost-effective solution for long term needs. Once the VTC system was installed and fully operational, all stakeholders at the Institute were fully satisfied. In fact, according to Mr. Dong Hee Ahn, Neuroo Digitech General Manager, “Once KIAS decision-makers saw how the NAV Pro AV over IP design scaled so easily to accommodate meeting spaces of various sizes, they almost immediately began planning for future phased expansions of their VTC capabilities by adding more NAV Pro endpoints to extend the reach of their knowledge sharing events.”
