Webinar Recording: Enterprise Collaboration With SMART Technologies and HARMAN Professional

Presenters from HARMAN Professional and SMART Technologies team up for this look at solutions designed for today’s workplace meeting spaces. In the HARMAN session, Paul Krizan covers the AMX Acendo meeting-space solutions, including:

  • Acendo Vibe (compact solution for presenting and sharing audio and video)
  • Acendo Core (an intuitive one-click interface for users to easily start their meetings with Skype for Business integration)
  • Acendo Book (schedule a room through a booking panel that connects to Office 365)
  • Trends in huddle spaces (including technology expectations)
  • How Millennials and real estate costs are affecting the workplace

Stephen Yao of SMART Technologies looks at its interactive displays for the enterprise, including the 2000, 6000, and 7000 Pro series. For each of these models, Stephen covers:

  • Where these solutions are best used
  • HyPr technology (for smooth, precision writing)
  • Ability to preview different inputs
  • Exclusive iQ technology
  • The number of licenses included with these solutions (and their value)

Paul and Stephen also answer many technical questions from the live attendees.

The IT Manager’s Guide to Managed Services

Let’s say you’re an IT manager for a corporation, and you’re seeking a better way to manage the video conferencing and AV systems the company relies upon. In this scenario, you will likely be exploring and comparing the managed services offered by different companies. Or perhaps you’re trying to determine if such services from a third party are necessary.

In this Wainhouse Research report, “Video Conferencing and AV Managed Services,” sponsored by AVI-SPL, you’ll get an overview of managed services in the context of video conferencing and AV systems. This paper makes an argument for the value of managed services and covers specific benefits. Some of the topics covered in this paper include:

  • Definition of managed services (including their features)
  • Myths about managed services
  • The difference between basic and advanced managed services
  • Spotlight on AVI-SPL managed services

AVI-SPL Webinar: Learn About AVB From Cisco and Biamp

On Wednesday, May 17, join us for a look at audio-video bridging from two of the industry experts in AVB. In this webinar, Cisco and Biamp look at the digital transformation that has converged AV onto the IT network. Reps from each company will discuss their abilities to help organizations of all types experience better meetings through AV/IT solutions on the network. Ginger Liu of Cisco and Chris Chandler of Biamp will help attendees learn how AVB affects Quality of Experience, scalability, and leads to lower TCO. Topics to be covered include:

  • Digitization in commercial spaces
  • Disruption in enterprise AV
  • Technology comparison and use
  • Platforms and roadmap
  • How AVB differs from DANTE and CobraNet

Codecs, Bandwidth, and Latency

In our Video Over IP post, we touched on the encoding and decoding process that makes it possible to send video signals over the network. Now let’s take a brief overview of the codecs — which are encoding and decoding protocols — that employ these processes.

Codecs that use about 10Mbps (megabits per second) are ideal for transporting networked AV since they won’t allow the signals to monopolize your network.  Conversely, a 10Gbps (gigabits per second) codec will use up all the available bandwidth on a 10-gigabit network link. On the plus side, the latency — the delay caused by the process of encoding and decoding a video signal — will be low for this bandwidth-heavy codec.

Mezzanine, Intra-frame, and Inter-frame

Mezzanine, intra-frame, and inter-frame codecs will look at the source signal in different ways before compressing it for transmission. You want to have the most bandwidth-efficient codecs handling your signals. Even though there will be a trade-off in latency, that trade-off can be acceptable.

  • Mezzanine: These include TICO and DSC compression codecs. Latency is very low, but they also use the most bandwidth.
  • Intra-frame: These are JPEG2000 and VC-2 codecs. More efficient than Mezzanine in terms of bandwidth, but unable to stream to laptops and mobile devices.
  • Inter-frame: H.264 and H.265. H.264 AVC is the most common codec in use today. H.265 HEVC is the next generation. Latency will be about 200ms in the best case, which is considered acceptable.

Crestron’s “State of Networked Video and Integrated System Design” offers an easy-to-understand overview of these codec types, and the areas you need to address to have an integrated system of video distribution and devices — including network management, control, and security.

Video Over IP — How It’s Done

In a previous post, you learned why video over IP makes sense. Now we’ll look at how to make it happen.

First, let’s define a couple of terms:

  • Encoding: When you encode data, you’re making it suitable for transmission over an Ethernet network. So an encoder distributes high-definition AV signals over an IP network. Video In can be HDMI, and Video Out is Ethernet. An example of an encoder is Crestron’s DM-TXRX-100-STR.
  • Decoding: As you’d expect, this means you’re making the signal suitable for an uncompressed HDMI transmission. So a decoder receives high-definition AV signals over an IP network. Video In is an Ethernet stream, and Video Out can be HDMI. An example of a decoder is the Crestron DM-RMC-100-STR.

In a point-to-point network, you can send a signal from a computer over your LAN to a display in another room. Both areas can have Crestron’s DM-TXRX-100-STR, and they don’t need a matrix switcher. You can also multicast from a single encoder that sends signals to each room that has a decoder and display.

You can also use those rooms as collaboration spaces, where you connect your computer so that your content appears on the display. The Crestron DGE-100 has the ability to receive the LAN stream, and also can take a local connection from a laptop. Watch this Crestron video to see how easy it is to create a network AV solution.
