Challenges and Solutions in AV Network Management

 

Creating a well-designed, resilient, and secure AV over IP network that is integrated into the overall technology infrastructure of a university campus requires funding for equipment, training for staff and faculty, and the creation of a diverse and dedicated AV support teams to ensure proper maintenance and operation of the AV systems. All this adds up to a seemingly unsurmountable series of tasks.

In a session of the DDMC, Dr. Joe Way, the Director of Learning Environments at the University of Southern California, along with his senior team of Raj Singh and Chi Lo, discussed the challenges they faced and their approach to resolving them in their own AV network.

 

 

Raj Singh kicked off our session with pointing out initial challenges of managing multicast traffic and traversing between different switches and VLANs for the AV system in USC. They performed a stress test with about 40 rooms to create a playbook for replication and put network and security team guardrails to contain the multicast traffic. Challenges also include securing IP traffic, issues with bandwidth, multicast routing, and multi-MAC exemptions. USC’s approach to network AV is a top-down approach, designing rules and systems first and then propagating down to individual rooms. Data hygiene is important in network-based AV environments, unlike traditional AV where devices can be easily connected and swapped out.

Chi Lo further discussed stress testing a network to ensure it can handle high bandwidth traffic, such as 4K video. Recommend testing all scenarios and maximizing bandwidth to guarantee network readiness for future needs. The importance of direct connection of encoders and decoders to the distribution switcher is emphasized. Firmware updates that allow traversing across multiple fabrics and implementing software based VLAN separation.

The conversation continued with a question about USCs networking approach for distributing AV over IP system. Layer 2 or 3 and why? With a flat layer 2 network and the need for a layer 3 model with edge routing to avoid the whole system going down if a point in the network fails. Raj spoke to the use of router stacks on each floor of the building and keeping the AV system separate to that floor. The approach includes a mix of layer 2 and layer 3 with direct connections to network switches for multicast devices, and a registration and monitoring system for security.

The importance of security measures in the network and how USC went through an approval process with its own network security team to ensure the firewall rules and ports were secured was also discussed in detail. They partnered with the CEO’s office and IT infrastructure early on to get their approval and blessing, which slowed down the process initially but ultimately fast-tracked everything else. They were able to develop policies and tools to monitor the system and detect anomalies. They also used software-based tools to see what type of process is causing issues in the network.

Tracking metrics becomes the priority once an AV over IP network is in place, one on the engineering side and the other on the IT side. They are looking at things like network bandwidth, CPU cycles, packet loss, latency, and connectivity. Exploration of self-healing solutions for issues like cameras going offline, which can be fixed by power cycling. The team is also focused on ensuring that all their devices are running the latest software to enable them to connect to different platforms like Microsoft Teams, Zoom,and Webex. Compliance and security risks are also taken seriously, and upgrades are made promptly when necessary.

In conclusion, the DDMC session featuring Dr. Joe Way, Raj Singh, and Chi Lo provided valuable insights into the challenges faced and solutions implemented in the AV network at the University of Southern California. From network security and software updates to equipment maintenance and user support, the USC team demonstrated a comprehensive approach to managing a complex AV infrastructure.

While we have summarized some key points from the session, there are many more details to be learned from watching the recorded video. Overall, this session serves as a valuable resource for anyone involved in AV network management, particularly in an educational or large organizational setting.

What Is A Microphone Array?

The use of technology in the classroom is becoming increasingly prevalent in today’s educational landscape. As schools and universities adopt new and innovative solutions to enhance the learning experience for students, one area of focus has been improving the quality of audio in the classroom. The DDMC recently sat down with Steven Pretzer, an AV support tech at Fuqua School of Business, to discuss the installation of three new microphone arrays in the McClendon and HCA classrooms. In this article, we will explore the benefits of microphone arrays over traditional tabletop microphones, the challenges of implementing them in a classroom setting, and best practices for their use.

  • What is a microphone array, and how does it differ from traditional table microphones?

 A microphone array is a microphone system that uses multiple microphones arranged in a specific pattern to capture audio in challenging acoustic environments. It uses beamforming technology to enhance sound coming from specific directions while reducing unwanted background noise and reverberation. The microphones are combined to create a virtual microphone that can be aimed and steered to capture audio from a particular area. It is often used in situations where multiple speakers are present, such as in a panel discussion or a classroom lecture and can provide high-quality audio for remote participants in video conferencing systems.

 A microphone array differs from a tabletop microphone in several ways. First, a microphone array is typically mounted on the ceiling or wall and can capture audio from multiple directions simultaneously, while a tabletop microphone only captures audio from a single direction. This allows microphone arrays to pick up a wider range of sounds and voices in a classroom setting, improving the overall quality of audio.

  • What are the benefits of using microphone arrays in a classroom setting?

 Using microphone arrays instead of tabletop microphones in a classroom setting offers several benefits, including the ability to capture sound from a wider area, reducing background noise and reverberation, being more discreet, and being more cost-effective in the long run. This enhances the learning experience for students and teachers alike by providing clear and intelligible audio in a range of challenging acoustic environments.

  • How do microphone arrays improve the quality of audio in a classroom environment?

 Microphone arrays improve the quality of audio in a classroom environment by providing clear and intelligible audio that can be easily understood by students and teachers. This is achieved through a combination of features, including the ability to capture sound from a wider area, reducing background noise and reverberation, and the ability to steer and focus the audio in real-time towards the person speaking. In contrast, traditional tabletop microphones can often be garbled and difficult to distinguish between speakers, particularly in larger classrooms or lecture halls. By using microphone arrays, the need for additional equipment, such as lavaliere microphones, can also be reduced, resulting in a simpler and more streamlined audio setup that is easier to manage and maintain. Overall, the use of microphone arrays can significantly enhance the quality of audio in a classroom environment, improving the learning experience for students and teachers alike.

  • What are some of the challenges associated with implementing microphone arrays in a classroom, and how can they be addressed?

 Implementing microphone arrays in a classroom can present several challenges that need to be addressed to ensure optimal performance. One of the main challenges is the complex acoustic environment of a classroom, which can include a variety of sound sources, such as students talking, moving around, and rustling papers. In addition, the shape and size of the classroom, as well as the placement of the microphones, can also affect the quality of the audio captured.

 To address these challenges, it is important to carefully plan the installation and setup of the microphone array system. This may involve using specialized software to analyze the acoustic environment and optimize the placement and configuration of the microphones. It may also involve walking the room and testing the system to ensure that it is capturing clear and intelligible audio from all areas of the classroom.

  • What factors should be considered when selecting a microphone array for a classroom setting?

 Installation type and location, backend interface. All play into the choice.

When selecting a microphone array for a classroom, factors such as installation type and location, backend interface, size and shape of the room, number of students and teachers, and the acoustic environment of the room should be considered. Ceiling-mounted microphones may offer wider coverage and be more discreet, while wall-mounted microphones can provide better directionality and control. The interface should be compatible with the existing audio system and any additional equipment that may be needed. Advanced noise reduction capabilities may be necessary for classrooms with high levels of ambient noise. By carefully considering the specific needs of the classroom and the capabilities of different microphone array systems, schools and universities can select a system that provides clear and intelligible audio for students and teachers.

  • How do microphone arrays improve the learning experience for students and teachers?

 Clarity, Clarity, Clarity!

 Microphone arrays can greatly enhance the learning experience for both students and teachers in the classroom. They improve the clarity of audio, reduce the need for repeating questions, and help the classroom flow more smoothly. Microphone arrays can create a more inclusive learning environment, making it easier for all students to hear and understand what is being said. This is particularly beneficial for students with hearing impairments or those who may struggle to hear in a crowded or noisy classroom. Overall, microphone arrays can greatly enhance the learning experience in the classroom by improving audio quality and creating a more inclusive environment.

  • Why use ceiling mounted microphone arrays in a classroom?

Ceiling-mounted microphone arrays can offer superior audio quality compared to other types of microphones, thanks to their advanced beamforming technology. This technology allows the microphones to focus on the speaker and filter out unwanted background noise, resulting in clear and intelligible audio for all students. While other types of microphones, such as wall-mounted or portable microphone arrays, may be suitable for certain classrooms, ceiling-mounted microphone arrays offer several key advantages that make them a superior solution for most classroom environments. By providing wide coverage, reducing disruptions, and delivering high-quality audio, ceiling-mounted microphone arrays can greatly enhance the learning experience for both students and teachers.

  • What are some best practices for using microphone arrays in a classroom setting?

A In line ducker in the DSP. Gain Structure. Focused on speech. High Pass filters. NOM limit of 1 with the ceiling arrays to keep the noise floor low and a lower hold time on the gating auto mixer to ease the transition between open mics.

 If something you’re doing is not making it better? Don’t do it!

 To optimize the use of microphone arrays in a classroom setting, there are some best practices that should be followed. Firstly, it is important to use an in-line ducker in the DSP, which will automatically lower the volume ofany background noise when someone is speaking. This can greatly improve the overall audio quality and intelligibility.

Secondly, attention should be paid to gain structure, ensuring that the microphones are set at the appropriate level to capture speech without picking up unwanted noise. Additionally, the microphones should be focused on speech, with any background noise or reverberation minimized using high-pass filters.

 Finally, it is important to remember that if a certain adjustment or change is not making the audio quality better, it is better not to do it. This can prevent unnecessary tinkering and ensure that the microphone arrays are being used in the most effective and efficient way possible. By following these best practices, the use of microphone arrays in a classroom setting can be optimized, resulting in improved audio quality and a more effective learning environment.

 Additionally, the advanced beamforming technology of microphone arrays allows them to filter out unwanted background noise, resulting in clear and intelligible audio.

 When selecting a microphone array for a classroom setting, factors such as installation type, location, and backend interface should be considered.

A New Kind of DDMC

Bryan Center Studio 1

We had great attendance for this DDMC meeting! Featuring a lineup of big hitters and an all-star cast in the gallery at Studio 1 made for a great event. A big thanks to everyone for your support!

Richard Mitchell made his return to the DDMC, wearing a well fitted Biamp Vest, to give us a rundown of the new Parle’ VCB2500 video bar that is shipping! He also provided overviews of Biamp’s new AV control product line, Video conference cameras, Devio conferencing, and an easy to use classroom designer. The Biamp product line does an excellent job of covering all of your educational technology needs.

Michael Greene and Chris Lorch from Duke Learning Innovation discussed the impact of digital learning technologies on the classroom and other learning environments and showed how active learning helps students think, create, discuss and solve problems rather than passively sitting in a class receiving information. They highlighted the use of whiteboarding to promote brainstorming and group work. Reducing the need for podiums, providing good sound and visuals, and promoting more instructor interaction with online students are all components that should be considered in this new landscape of HyFlex teaching at Duke University. DLI is Duke’s resource for faculty and staff to tap into the opportunities that hybrid teaching tools can provide.

John Ballinger and Tim Hunnicutt with Panasonic brought an impressive array of PTZ cameras, video switchers and auto-tracking technologies to studio 1. John spent some time featuring Panasonic’s auto-tracking, which uses high-performance motion detection and high-accuracy facial recognition. These features allow precise tracking of the subject with minimal tracking errors, regardless of the direction the person is facing, even when the lecturer has his/her back to the camera. In addition, since this function provides detection/tracking with streaming video from the camera, the video capture board typically needed for capture on a PC is no longer required. This reduces the processing load for video capture, thereby eliminating the need for a high-performance PC. I also want to note the new PressIT 360, an easy to use plug and play conferencing camera ideally suited for small collaboration spaces.

Finally, our own Stephen Toback presented a topic near and dear to his heart: How to build a 4k studio for under $4,000. Knowing that the Bryan Center Studios will not always be convenient or the right place to shoot your video, Stephen put together a concise list of features your 4k studio should have in order to be successful. Room size, shape, acoustics, and lighting should all be considered before purchasing cameras and microphones. Stephen’s 4k studio equipment list details everything you need to outfit a studio of your own.
