Extron NAV & Streaming Systems Serve the Chef for St. Helena High’s Culinary Program
Integration of Extron's NAV Pro AV over IP system and the SMP 111 streaming processor lets the students at home be on the same page as those in the classroom, making this AV system just what the chef ordered.
St. Helena High School is a top-ranked institute of learning in California's Napa Valley wine region. The county is filled with luxury hotels and Michelin-starred restaurants, such as The French Laundry. Because of this wealth of fine dining and high-end accommodations, the high school offers programs that prepare students for careers in hospitality and the culinary arts.
For the culinary classroom, a new AV system would enhance instruction and enable students attending from home to have as close to an equal experience as possible. St. Helene High brought in E.R.I.C. Low Voltage Services to design and program and Consolidated Networks Corporation – CNC to integrate a
NAV Enhances Classroom Learning and Demonstrations
The culinary classroom includes six full commercial kitchens, and the instructor is Chef Karl Turner III. Previously, the students gathered around the outside of the kitchen to watch the professional chef prepare and plate the gourmet dishes. Visibility was an issue. A rudimentary AV system was introduced, with the video sourced from a GoPro camera that the chef wore around his neck or on his toque hat. While this did improve visibility for students, the camera was cumbersome and the single point of view had limited value. Later, a closed-circuit TV system was installed, with RG 59 to BNC connectors going from PTZ cameras directly to receivers installed behind the 55" wall-mounted displays. A network solution with streaming capabilities was the next step.
The NAV Pro AVoIP system ties three broadcast-quality 4K HDMI PTZ cameras to the existing 55” displays, as well as provides content to the streaming system. An Extron

SMP 111 Streams Each Step for Budding Chefs
Three years ago, CNC upgraded the school to a CAT 6 cable infrastructure that provided a 40 Gbps backbone with at least a 10 Gbps uplink between the switches. Currently, the system maintains 40 Gbps with up to 100 Gbps in some spots of the switching architecture. This gave the school the bandwidth needed to support streaming. The Extron SMP 111 streaming media processor was a perfect fit. The single-channel, H.264 streaming media processor captures and distributes the camera feeds and other resources for selectable live streaming.
The content can be streamed to the offices of the school officials and any classroom on campus, as well as to the students attending class from home. The SMP 111 also provides simultaneous recording of the HDMI video and audio. Recordings can include metadata, such as a date and time stamp, the chef’s name, the title of the recipe, and the technique being demonstrated.
From concept to commissioning, the entire project was completed in two weeks. CNC credits this in part to Extron’s well-designed products and the support engineers. The administration is quite pleased with the success of the AV system upgrade in the culinary classroom, and Chef Turner III is happy with how easy it is to use.
At the chef’s request, a fourth PTZ camera is being mounted to the front of the vent hood. It will allow each student to see a hands-on view of the chef at work. According to the programmer, adding to a NAV system using GC Pro only requires very little time. “In my experience of programming products from a wide variety of AV manufacturers, NAV is by far the easiest system to configure and program, and Extron support is top notch,” says Eric Marshall of E.R.I.C.
