Volume Control – Who’s the boss?

Written on April 26, 2017 at 12:38 pm, by

 

Many AV installers have multiple systems they run into a single amplifier, using  a single, integrated control system for room volume.  The amp is often one of the longer-lasting pieces of room equipment, and once set, most AV techs know not to “mess” with it.

 

When using Clearone professional audio DSPs, AV techs almost always connect to an existing amplifier.  However, many amps that were in use with legacy equipment or non-conference applications are turned up far too high for use with a DSP and conference audio.

 

This isn’t because the volume in the room is too high. In fact, it will often sound great to the installers.  It’s actually because the DSP functions best when the signal sent to the amp is at 0 dB on average.  It’s tempting on new installs to turn down channels in the DSP to conform to an existing amp that’s set at 50% or higher, but this will degrade the DSP’s acoustic echo cancellation and cause choppy RX audio from the conference.

 

Always calibrate a DSP to 0 dB for all inputs, and outputs, and tune the amp down accordingly.  It’s not uncommon for an amp to be at 30% or lower when used with an AEC-enabled system like the CONVERGE® Pro 2.

Wireless Presentation Gone Mainstream

Written on April 5, 2017 at 10:58 am, by

 

You probably get this familiar type of call quite frequently:

 

Mr. Customer is searching for a wireless data-sharing solution – and the strangest part is that he may reference a specific brand-name of solution instead of the technology itself.

 

Those of us who are not quite so young anymore might remember those types of calls, in the end of last century, when customers were inquiring about a specific brand of conferencing solution when a more general executive phone was actually needed for simple audio-conferencing activities.

 

That is a sign that a technology has “made it.” It has gone mainstream!

 

One vendor discovered and delivered a much-needed new product concept in the market, found a new intuitive and natural way in which people can collaborate. A new niche, a new opportunity for business has surfaced.

 

Wireless data sharing became a fundamental component in meeting rooms of the new millennium. Employees and business guests expect it…it should simply be there for agile and productive collaboration.

 

And now Mr. Customer calls in, knowing he should be prepared to spend a couple thousand for even the most basic configuration – all his budget will allow.

 

What Mr. Customer does not know yet, and you may want to inform him, is that the wireless-data-sharing-box concept he is looking for has been by far surpassed by the new outstanding ClearOne COLLABORATE® Share!

 

For almost the same price, Mr. Customer would receive so many features that a sophisticated sales pitch simply isn’t needed. With COLLABORATE® Share, he is not only increasing the potential of his buy, but he is also getting, basically for free, a state-of-the-art H.323 codec and cloud collaboration suite – all three fully integrated in one, simple, intuitive user and administration interface.

What is 4:4:4 color and why should I care?

Written on March 15, 2017 at 5:45 am, by

 

In the AV industry we pride ourselves on providing the best-quality audio and visual communication to our clients.  One way in which we can do that is to offer video solutions in 4:4:4 color.

 

 

When digital video was first introduced, video files sizes were large in relation to storage and transmission capabilities.  One of the ways to address these larger file sizes was to introduce “chroma sub sampling.”  In digital video there are two main components; Luminance and Chrominance.  Luminance (or contrast) is the difference between the lightest and darkest parts of an image.  Chrominance is the color saturation of an image.  The human eye is very sensitive to small changes in contrast (Luminance) and is less sensitive to changes in color saturation (Chrominance).

 

 

To make digital video files more manageable, compression was introduced.  A true-color video signal (4:4:4) includes all of the red, green, and blue color information of each pixel.  In a 24-bit system, there are 8 pixels for each color and thus 24 bits in true color.  Chroma subsampling reduces file size by removing color.  In the AV world, the most common color space is 4:2:0, which is DVD quality. However, with 4:2:0 quality, the viewer is only seeing 50% of the available color.  To make up for that loss of color, the pixels that were removed are recreated by borrowing or “interpolating” from the adjacent pixels.  In some instances 4:2:0 quality is perfectly acceptable.  In other instances however the chroma sub sampling provides the viewer an experience that is less than optimal.

 

 

I can think of at least three instances in which 4:4:4 color is required:

 

  1. Telemedicine:  Surgical procedures streamed over a network require extremely accurate color information on the receiving end.
  2. Spreadsheets: Small text on a spreadsheet in color is virtually unreadable at anything other than 4:4:4 quality.
  3. Corporate Branding: Accurate color representation in a company logo.  Think of how some iconic brands might appear if the colors were not accurate represented.

 

 

If two video streams with identical content are placed next to each other, one at 720P 4:4:4 color and the other at 1080P 4:2:0, chances are extremely high that the average viewer will choose the lower resolution image with the true color as the more impactful.  Color trumps resolution pretty much every time.  So the next time you are specifying a streaming solution make sure to factor in which color space is most appropriate for the application.

Happiness at the Office- PART III

Written on February 22, 2017 at 12:21 pm, by

 

Today we’re going to wrap up our series on “Happiness in the Office”. In Part I and Part II, we looked at the overall concept of happiness at the office, and 12 ways to exploit your own happiness.

 

Below is a bit more information on the ClearOne Spain office and their “Thanks Portal,” which is a concrete way they are encouraging office happiness:

 

The “Thanks Portal,” initiative at the ClearOne Spain office, combines the overall happiness strategy, gamification, and social relationships to cultivate a positive mindset among employees in a simple way, without changing daily work routines and without losing time.

 

The basic premise of the Thanks Portal is to express gratitude and focus on positive experiences and random acts of kindness. These simple acts all change peoples’ outlooks, the very way in which your brain views “work,” to create and sustain a positive and engaged workforce.

 

The portal allows fellow employees to post “stars/positive points” about encounters with other employees; the intrinsic reward being simply to receive more and more of these positive comments. The social relationship between employees is well-documented as the greatest predictor of happiness during periods of high stress, and a positive social relationship creates positive habits.  It can have favorable outcomes both on employees (e.g., job satisfaction, increased well-being) and the organization (e.g., commitment, collaboration and productivity).

 

We know we’ll see nothing but increased creativity and efficiency from the Spain office, as they continue this unique and fun way to add happiness to the office!

 

Let us know what you’ve done in your workplace, or what you’ve seen in other areas that help everyone to be more positive and more fulfilled.

 

Here’s to your Happy Office!

A better Video Conference User-Experience with Spontania’s Simultaneous Four-Camera Support

Written on February 1, 2017 at 7:30 am, by

 

With video conferencing becoming a necessity for most corporate, SMB, education and other organizations, how do the various Video Conferencing solutions really differentiate themselves from one another?

 

They all make the promise of being simple and intuitive; allowing you to save money and time by avoiding hundreds of miles of travel. They offer popular features like content sharing, recording, and even whiteboarding.  But despite the promises, the reality was, for many remote participants, these solutions just weren’t maximizing on the video conferencing experience. Many participants found that by being remote, it was easier for them to become distracted and lose focus. Some users were so busy, they often found themselves multi-tasking and weren’t even focused on the meeting. And for others, doing a remote video call was just plain boring.

 

 

So how can you eliminate that feeling? What if you were able to provide your remote users a feeling of being on-premises, of actually being there in that conference room or classroom with everyone else,so that they could see everything and everyone, and truly feel like part of the meeting?

 

How do you create that feeling for remote users, all hundreds of miles away?

 

 

We do this with Spontania’s ability to capture 4 simultaneous camera views. Far-end participants now see everything that’s going on, giving them the feeling of actually being there in the classroom or conference room.

 

Here’s a training scenario for using 4 cameras:

 

One camera is pointed toward the front of the room, to see the instructor’s every move.

 

A 2nd camera is pointed at the attendees, so if a question is asked, the remote participant can see who’s asking it instead of just hearing it.

 

A 3rd camera can be pointed at a whiteboard for instructors who prefer to make quick notes by hand, an ASL interpreter, or any other angle that adds to the overall experience.  The participant now can see what’s written in real time and take notes accordingly.

 

The 4th camera can be a document camera. So, if the instructor needs to show an object to the class, the far-end participants won’t struggle with just having a minimal view. The instructor simply positions the object under the doc cam and the remote participants see it up-close; as if they were there in the room.

This is just one use-case example ; you can use 4 cameras to provide a multi-view product demo or even set them up for a full 360 degree views.

 

The possibilities are endless.

 

Whether you’re a business, a university, a law firm, or just have a huge conference room, the 4-camera support included with the Spontania Video Collaboration platform is an instant professional experience for your participants, clients, students, colleagues, and end-users.

 

Video conferencing software and hardware is an investment, so why not take advantage and get the best value with that investment?

 

Your far-end participants will thank you.

Happiness at the Office- PART II

Written on January 11, 2017 at 10:10 am, by

 

In PART I, we  looked at the overall state of happiness in the workplace. Now, we look at the ways in which to exploit your capacity for happiness…

 

———————————————————————————————

 

Sonja Lyubomirsky, Professor of Psychology at the University of California, Riverside, (The How of Happiness) indicates that 50% of individual differences in happiness are governed by genes, 10 percent by life circumstances. This leaves a startling, and startlingly underdeveloped, 40% of our capacity for happiness within our power to change.

 

 

She explores 12 ways to exploit that 40 percent:

 

  1. Counting your blessings: Expressing gratitude for what you have (either privately – through contemplation or journaling – or to a close other) or conveying your appreciation to one or more individuals whom you’ve never properly thanked.
  2. Cultivating optimism: Keeping a journal in which you imagine and write about the best possible future for yourself, or practicing to look at the bright side of every situation.
  3. Avoiding overthinking and social comparison: Using strategies (such as distraction) to cut down on how often you dwell on your problems and compare yourself to others.
  4. Practicing acts of kindness: Doing good things for others, whether friends or strangers, either directly or anonymously, either spontaneously or planned.
  5. Nurturing relationships: Picking a relationship in need of strengthening, and investing time and energy in healing, cultivating, affirming, and enjoying it.
  6. Doing more activities that truly engage you: Increasing the number of experiences at home and work in which you “lose” yourself, which are challenging and absorbing.
  7. Replaying and savoring life’s joys: Paying close attention, taking delight, and going over life’s momentary pleasures and wonders – through thinking, writing, drawing, or sharing with another.
  8. Committing to your goals: Picking one, two, or three significant goals that are meaningful to you and devoting time and effort to pursuing them.
  9. Developing strategies for coping: Practicing ways to endure or surmount a recent stress, hardship, or trauma.
  10. Learning to forgive: Keeping a journal or writing a letter in which you work on letting go of anger and resentment towards one or more individuals who have hurt or wronged you.
  11. Practicing religion and spirituality: Becoming more involved in your church, temple, or mosque, or reading and pondering spiritually-themed books.
  12. Taking care of your body: Engaging in physical activity, meditating, and smiling and laughing.

 

 

Based on this strategy list, the ClearOne Spain office has implemented a happiness strategy, what we call the “Thanks Portal.”

 

 

Stay tuned for more exploration on the ongoing uses of the “Thanks Portal” and the value of employee recognition.

 

 

 

The Case for Audio Making or Breaking Video Communications

Written on January 3, 2017 at 3:06 pm, by

 

It’s easy to see video conferencing and collaboration as the “next step” in communications, something beyond the world of audio conferencing. However, the truth is, a video conference is only as good as its audio. The occasional dropped frame or even severe video issues can still be forgiven in a conference without interrupting the flow.

 

However, if audio becomes choppy, it quickly becomes fatiguing to listen or to repeat statements or questions… and worse, if audio is missing, there simply is no conference to be had.

 

Tune in an find out why great video collaboration can only be built on a solid foundation of superior audio. Ron Lynch, ClearOne’s Supervisor Technical Trainer, provides an overview of why strong audio is an absolute necessity in video conferencing and collaboration, in conjunction with Commercial Integrator:
