Audio Visual technology played a significant role within major global events of 2012. Both the Democrat and Republican conventions utilized the technology as a vital tool to nominate their leaders. The events were broadcast to millions of Americans and the footage was transmitted to almost every news outlet around the world. With the stakes set so high, a technological failure would have catastrophic consequences– resulting in a failure to communicate a party’s message.

AV ExhibitsLondon 2012 also stands out as an Audio Visual spectacle, with the Olympics’ coverage featuring the transmission of the athlete’s performance around the globe as countries celebrated the games. One of the most notable elements of the critical AV coverage was the huge video wall present. Capturing both these events in real-time provides a unique public experience which can influence, enthuse and arouse emotion amongst the world’s population. AV technology is undoubtedly predominant on the global events stage, but it is equally important within smaller exhibitions where the role that digital media takes has undergone a transformation in this industry.

The Guardian’s B2B network recently held a live debate to examine these changes as businesses seek to diversify their customer engagement through interactive AV technologies. The role of the exhibition has been able to extend itself from an exclusive business meeting to a global PR campaign which has social interactivity as an accessible feature integrated into its AV. Digital displays serve as marketing tools for brand exposure and can demonstrate a products potential and encourage audience participation. The digital revolution may have been a famous phrase of the 1990’s yet not all businesses are realising its potential to engage consumers in the exhibitions industry.

Let’s consider the development of Brand Engagement, Social Media and Augmented Reality through the Audio Visual medium and how small exhibitors can leverage this technology to the public.

Brand Engagement

AV ExhibitAn exhibitor stand can harness a brands power through a digital display and interactive interface. Digital displays provide a contemporary approach to display marketing. Customers are drawn to the exhibitor stand and are subsequently more likely to engage with the stand staff. Web interfaces and interactive flash games can mirror the brands personality and provide a focal point and engagement tool for your stand.

Social Media

Accessing social media through the interface encourages consumers to promote the product which is great brand exposure. Social tools such as Twitter, LinkedIn and Pinterest; should be at the heart of the live marketing strategy and encourage product information to trend. The brands success is dependent upon a genuine consumer relationship and the product excitement can be marketed before, during and after the show. Encourage all audience members to participate.

Augmented Reality

Augmented reality blurs the lines between what is real and computer generated and applications which enhance the customer experience could become the most revolutionary aspect of the exhibitions industry. Exhibitors are currently using smart phone applications to add a dimension to their display, turning them interactive and providing virtual environments within the exhibitor booth.


Lip Synchronization Is Part Of Show Business

Let’s Not Crucify Beyoncé For Lip-Synching

By Paul Konikowski, CTS-D

I remember my first paid lip sync experience like it was yesterday. It was about 10 or 12 years ago. I was working a Halloween-themed multi-act concert with a local professional sound company.  In addition to the load-in and load-out, my responsibilities that day included handing out the wireless handheld microphones that each act was utilizing. Moreover, it was my job to make sure the wireless microphones were working correctly without any interference, and that the artists returned the mics as they left the stage.

Since the music expo was sponsored by a local top 40 radio station, it featured a lot of one-hit-wonders who did not have full albums out yet. Many of the hip-hop performers did not carry any instruments. Instead, they would sing over pre-recorded compact discs, oftentimes hiring multiple backup dancers before any touring musicians.   In the live sound business, we refer to these boy bands and girl bands as ‘track acts’.  Now to be clear, a track act and lip synching are two different things; track acts generally sing, at least part of the song, but let me get back to my story.

One of the track acts we were supporting that day was a duo of teenage girls, along with some backup dancers. Their technical rider requested two wireless mics, which they used to introduce themselves.  But when they began performing the songs, it was obvious to me, and anyone looking at the meters on the corresponding wireless receivers (or the meters on the mixing consoles), that these girls were definitely not singing. It was all track.

Wireless microphone receivers have meters that indicate when batteries are low, as well as when the performers are actually singing (Image courtesy of

I bit my tongue and tried not to laugh.  These two teenage girls were performing difficult, choreographed dance moves I could never imagine doing, even after an entire season of being on Dancing With The Sound Guy.  The audience cheered for their entire set of three songs.  So who was I to say they were not performing their songs, even if they were not singing?  If the instruments and backup vocals are pre-recorded, what is wrong with canned lead tracks? There is a good chance they didn’t write the lyrics or melody in the first place. It was probably handed to them on a compact disc, with Post-It Note instructions: “add dance to this”. So who care’s if they sing or not?

Graduate Synch School continued later that night, as I began to setup the stage for a three-man “DJ super group”. I use both terms very loosely, because there were certainly no discs or records being jockeyed, nor was there anything super about this group.  It was basically three electronic music producers who stayed up all weekend and wrote a hit song on a laptop, and a few other songs that were not as popular. 

So back to the stage, this electronica trio included two guys on keyboards, one of which was the cool 80’s “strap on” version that hung off the shoulders using a guitar strap.  But it didn’t matter, because neither keyboard was plugged in!  They were both just props!  The third guy was the only “real” performer in the group, as he sang the lead vocals using a vocoder over three pre-recorded tracks.

I thought to myself, “can these guys really respect themselves as music producers, while pretending to play keyboards that were not even plugged in?”  I guess the fake keyboards gave Thing 1 and Thing 2 something to do on the stage while the lead guy sang the leads. Who was I to say it was not live performance?  The crowd didn’t seem to mind at all.

Which brings me back to Beyoncé. We all know this modern-day diva can sing, LIKE A BOSS. That is why everyone tuned in to hear her sing, and applauded when she finished. It was not until a Marine Band member came forward to say she may have lip-synched, that suddenly, Beyoncé was in the middle of a scandal questioning her patriotism. Shame on you, mainstream media, for jumping on this bandwagon, and not defending her honor. You should know as much as anyone, that just like applying makeup, or throwing your voice, lip-synching is an art, not a crime.

Moreover, the Star Spangled Banner is never an easy song to sing, because it spans so many octaves. On a good day, you might mess up a few words. On a bad day, you might sound like Roseanne.  It’s not like Beyoncé took any performing enhancing drugs to sound better in the Vocal Olympics.  It was a ceremony. It was still her voice, and everyone still applauded. It was not unpatriotic; it was part of a Patriotic performance.

We all know professional wrestling is fake. It doesn’t mean that they are not athletic, and that it’s not dangerous, or difficult to do their job. But in the end, they are performers, not Olympians. Those wrestlers follow a script, just like Beyoncé and everyone else did on Inauguration Day 2013.

Let’s face it: lip synching is a part of show business, just like acting is part of politics!

MHL: Mobile High-Definition Link

MHL, A Must See at CES 2013 In Vegas, Baby!

by Karin Vogel, Director of Consumer Marketing, MHL, LLC.

What Exactly Is MHL?  Does My Smartphone Or TV Have MHL?

I recently joined MHL because of their staggeringly cool technology.  MHL stands for Mobile High-Definition Link and it was created by some of the world’s leading mobile and CE companies – Nokia, Samsung, Sony, Silicon Image and Toshiba.  Think of it as a way of sending your pictures, video, and audio from your Android smartphone, tablet, or portable device to your high-definition television and other home entertainment products such as AVRs, Blu-ray Disc players and streaming media devices. But there’s a lot more to MHL than meets the eye: it can charge your phone, and supports full surround sound (7.1). You can even stream movies from Netflix or your Roku streaming stick in high-definition (1080p). Better yet, use your TV remote or game controller to control the content being sent from your smartphone to the TV.

To find out if your smartphone and/or TV is MHL enabled, click here.  If you have an MHL Smartphone, but your TV is not listed as MHL enabled, you can use an MHL-to-HDMI adapter, as illustrated below:

MHL Smartphone to MHL TV OR MHL Smartphone to HDMI Adapter

Level Up While You Power Up

MHL adds a whole new dimension to video gaming. Imagine you are on the bus on the way home from school or work, playing your favorite game on your Android smartphone or tablet, and your phone battery is running low. When you get home, what if you could plug your smartphone into your television using an MHL cable or adapter, and have your phone battery charge? You then grab your favorite snack and wireless Bluetooth gaming controller, sit back on the couch, and continue playing the same game you were playing on the bus with no lag or interrupted game play; except now you are playing on a much larger screen, using a real gaming controller!

In this imaginary scenario, your smartphone IS the gaming console, but it still has all the other capabilities and apps of a phone.  Now imagine your phone becomes the controller, which you need for racing games to navigate runways, speedways, and waterways at thrilling speeds.  But guess what?  It’s not a dream.  With MHL technology, you can have it all, the ultimate mobile gaming experience.

Accelerate Your Automotive Infotainment System

Watching movies in automobiles is nothing new, and many people are already connecting their smartphone or MP3 player to their car’s sound system.  So what makes MHL different?  Because MHL is more than just audio and video, you can also use the dashboard display in your car or truck to access the automotive apps already on your phone (without getting a ticket from the police).  Just plug-in your MHL smartphone, and away you go!  Use Google Maps or other GPS navigation, and get real-time traffic updates. Cool, huh?

You can also lookup restaurants, stream TV shows, or order movie tickets all through your phone apps. Of course, MHL doesn’t propose doing any of these actions while you are actually driving, but you could safely park and, order a pizza, check your email, and then get directions to where you are going before you start driving again. Or have your co-pilot handle everything. With MHL technology you can charge your phone while you are driving. Just like at home, you can stream movies or live television using your phone, show video on backseat displays and hear the audio from the car’s sound system, or in full surround sound (if your car has a 5.1 or 7.1 speaker system). As your phone evolves, your experience will continue to grow, and most importantly, your content grows with you.

Where I Can I Find MHL At The 2013 International CES Show?

The MHL Consortium will have a booth in the Gaming Pavilion at the Las Vegas Convention Center, South Hall 2 – #25700. On one side of the booth there will be a gaming station; on the other side there will be a home theater station with a TV and Roku Streaming Stick. I will be there in the booth to answer any questions you may have. This year MHL will also be in Hyundai’s booth, where they’re sharing some pretty exciting news…that we’re itching to tell you, but can’t just yet.

Since MHL is a Consortium, our technology will also be featured in a number of other booths on the show floor. Look for MHL to be demonstrated in concept cars’ dashboards, in Blu-ray players, televisions, A/V receivers, and of course mobile smartphones and tablets. If you would like to schedule a press briefing or similar MHL meeting at CES 2103, please call Kristin Uchiyama at 408.313.0448 or email

See you in Vegas, baby! – K.V.
