Biamp is now shipping its TesiraLUX product line of video streaming solutions to its global base of customers.
The TesiraLUX suite, utilizing IEEE Audio Video Bridging/Time-Senstive Networking (AVB/TSN), includes an AVB video encoder (TesiraLUX IDH-1) and an AVB video decoder (TesiraLUX OH-1). The encoder features one HDMI port, one DisplayPort port, and includes two mic/line level analog inputs. The decoder includes one HDMI port and two-line level analog outputs.
A Single Software Environment for Networked Audio and Video
While video over Ethernet is nothing new, Biamp sees increased value in offering a holistic ecosystem for networked audio and video. TesiraLUX natively integrates with the entire Tesira platform, therefore installers and tech managers can use a single software environment for both audio and video. It integrates streaming video with audio DSP; no breakout boxes or workarounds are required to get audio and video signals to work together.
TesiraLUX supports advanced video formats including 4K, 4096×2160 at 60Hz, high dynamic range (HDR), and the Rec. 2020 color space. It can accept video at up to 16-bit color depth with 4:4:4 chroma subsampling. It also supports eight channels of embedded PCM audio which can be broken out to be routed and processed independently. 1GB and 10GB connections are supported.
“AVB is the sanest and fastest way to manage network bandwidth usage and traffic for applications streaming audio and video,” Chris Fitzsimmons, Video Products manager of Biamp Systems, told AV Technology magazine yesterday. “It sets up faster, doesn’t require chattier protocols (such as IGMPv2) and won’t force the client into unnecessarily provisioning their switch infrastructure to ensure no bottlenecks occur.”
Fitzsimmons added that TesiraLUX also does not use special networking technologies (e.g. Jumbo Frames) which can interfere with other switch traffic.
The Networked Landscape: Where Does AVB Fit?
With 132 manufacturers shipping its products, Audinate’s Dante is the best-supported audio protocol, far outstripping the other technologies combined. But AV/IT industry stakeholders, including Cisco, Meyer Sound, and Biamp, believe in the potential of open standards such as IEEE AVB/TSN as technologies evolve. An often misunderstood element of AVB/TSN is that they are not communications protocols. Like VLAN and Power over Ethernet, AVB/TSN are core network capabilities that can be used by any (open or proprietary) communications system that needs them.
The AVB core and specs of the Biamp TesiraLUX line are “very promising,” said Phil Hippensteel, PhD, AV Technology contributor and instructor at Penn State Harrisburg. “[It offers] very high quality video, extremely low bandwidth, and guaranteed bandwidth availability.”

These days, the term “mega projects” indicates large buildings for public assembly, such as sports complexes, corporate headquarters, and transportation facilities like airport shopping centers, said Ted Leamy, senior vice president for Panasonic’s AV direct sales group. “These sports venues are not stadiums but are becoming meeting grounds. They’re multi-function spaces hosting rodeos, concerts, and other events.”
|Panasonic’s 84-foot video display, created for the Sacramento Kings, is regarded as the largest single piece of digital signage in the NBA.|
In fact, mega projects are actually campuses, often with entire restaurant and entertainment districts, associated hotels, and sometimes small convention centers. “In sports venues, for example, the premium club spaces are still revenue generating on non-game days,” he noted. “Any one of the big names in the corporate world have these large, multi-building campuses where people spend a large percentage of their day, beyond the eight-hour workday. In our world of AV, we want to treat that entire campus as a single AV system, even on one with multiple venues. We need to be able to transmit both audio and video throughout the campus with each venue standing on its own.”
Leamy pointed to SunTrust Park and The Battery Atlanta as an example of a mixed-use area of residential and commercial, “The walk-through neighborhood draws you into the game. Even if patrons don’t go to the game at one of these mega projects, they may arrive hours before to experience a concert in the plaza, dinner, a visit to the hall of fame or a museum. These are really meeting places to support folks through the whole day, and it’s the same with mega corporate spaces.”
A CAMPUS IS A CAMPUS
The concept of a campus goes beyond sports; it’s about the idea of creating campus standards, Leamy said. “The IT department is a factor because we’re transporting AV over the existing enterprise IT network. AV is one of several factors that are dragged into these campus-wide standards. This requires standards that are flexible and comprehensive enough to fit the needs of many different types of users, so we have to create systems and control GUIs that the average user can easily operate.”
This, he added, is the challenge for both integrators and designers. “There is a lot of thought that goes into the engineering and designing for these multiple functionalities that must be presented to the user in a simple fashion. Increasingly, it’s the AV integrators who need to have people onboard who are experts in enterprise network systems.”
Mega projects can absolutely incorporate the latest technology while still being user friendly. “The newest technology is based on IoT,” Hanak said. “As the standards become clear the technology is less costly, easier to use, and more impressive. If I had told you 15 years ago that by now we’d be able to search the web, listen to music, and videoconference on a single device, you wouldn’t have believed me.
“Now, a lot of folks are multitasking and we’re talking about the ‘latest and greatest’ technologies,” he added. “The root technology is here, but it’s on the application side that we’re creating exciting things for fans to interact with. We want to give a platform for our clients to scale beyond the solution because we don’t know where it’s all going.
Another interesting aspect, Leamy said, is the interoperability of the systems that allow owners to monitor, maintain, and adjust most systems that are part of a converged IT full blown network. “This idea of interoperability between audio and video, security, and building management, etc. is driving this. It’s not the technology; it’s the ease of use.”
BEWARE THE CREEP
The solution for preventing scope creep, Hanak suggested, is to have that detailed and “painful discussion” early on. “Regardless of size, many projects have the same elements,” he said. “Look at the holistic scope of the project and be diligent from the beginning. The more energy put in at the front end, the fewer gaps you’ll have to deal with down the road.”
Often, what happens is that people don’t take the time or have a checklist ready at the front end, Hanak continued. “We are checklist driven, we have a scope matrix, and we communicate with our clients to make sure it matches up and to identify any gaps. Doing your R and P (research and planning) will provide clarifications. You have to speak up and address gaps early on. Prioritize items that can cause the most economic damage. And sometimes the bidder who made the biggest mistake wins because if you guarantee the job and you made a mistake in your estimation, why not pick you?”
NOW HEAR THIS
Audio and video in these projects is more intertwined than ever before. “It’s all about the experience created—especially in sports—for fans’ expectations, encompassing many senses,” Leamy said. “Audio is a big part of that. How do we draw fans into the experience, including real-time social networking, and the many facets of engagement? Audio, more than ever, is not forgotten and pays a big role in achieving that goal.
“Our roles in these mega projects is challenged as these budgets become extraordinarily large,” he cautioned. “It takes a high level of design to ascertain that the correct kind of audio matches the space. Audio is the number-one criteria to convey information; intelligibility measured by the standard of speech transmission index for public address is critical to design. Speakers and components today are advanced, allowing us to provide great intelligibility along with a fun music experience and dynamic musical range.”
In the past, there was a choice to be made between providing a clear announcement or big, fun music. “Now, componentry is capable of offering both, but it’s important to remember that it’s application specific,” Leamy said. “You need the right piece and that goes back to the extraordinary amount of design engineering necessary to meet owner and fan expectations.”
BIG IS BEAUTIFUL
The bottom line, Hanak said, is that these larger projects start earlier. “With more runway you can do things that are more interesting. With a year and a half timeline, you have an opportunity to develop intimacy with the client, to see what’s coming over the horizon, and to make some changes. In general, with this time, we can do some interesting things.”

MEGA PROJECT, MEGA LIGHT
When it comes to mega projects, don’t forget about power control for AVL, cautioned Mark Bishop, president, LynTec.
In any install, most AVL equipment is being used only three to five percent of the time, he said, so it goes without saying that large venues need robust power control. “The ability to turn these solutions on and off at the circuit level not only reduces the overall cost of operations, but also dramatically increases the lifespan of your equipment.”
Bishop noted three major challenges for AVL mega projects, including that of space. “End users want as much public space as possible and often view electrical rooms as ‘wasted space.’ Be aware of your real estate needs when considering power control,” he said. “Relay panels will often take up twice the wall space of motorized circuit breaker panels by virtue of the fact that relay panels have to connect to a conventional circuit breaker panel. Be prepared to defend your territory.”
Allow for future expansion, Bishop added. “If history has taught us anything, it’s that new technology is always right around the corner, and circuiting needs go up, not down. It is much easier to build in expandability from the beginning than to try to add it after the fact. There will never be a time where you will need less circuits, especially in these mega installs. ‘Oh no! I have too many spare circuits!’ is something no one ever said.”
Finally, remember communication is key, he said. “Communicate your needs to the electrical engineer, the electrical contractor, and the end user. Attend all meetings. Don’t just tell them what you need, but explain why you need it. Power control isn’t the shiniest or most sparkly part of the system and it can easily be overlooked by those who don’t realize how important it is. Without power control, none of the other technology will run. Strong power foundations are just as important as the multimillion dollar lighting arrays they support. Spending a little more time explaining your power control needs in the design/pre-construction phase will save a lot of time and money in the long run.”

Users of Dante networks are now able to create quick Dante endpoints, promises its Australian developer Audinate, thanks to the introduction of the Dante Analog Output Module. The device is a small-form factor PCB with appropriate analogue connectors that can be used in small footprint enclosures.
The module supports one RJ-45 Dante input, and one or two balanced analogue outputs. It can receive audio channels from a Dante network and provide studio-quality, low-latency audio via balanced output connectors to analogue audio equipment. According to the manufacturer, any audio available on the Dante network can be routed via the outputs to an amplifier, powered speaker, mixing console, digital signal processor or other analogue audio device.
Planar Clarity Matrix Video Wall MX46HDX and LX55HDX feature 1.7mm tiled bezel width for nearly seamless LCD video walls.
Planar and Leyard recently announced the addition of two models to its Clarity Matrix LCD video wall system, each featuring a 1.7mm tiled bezel width for what the companies call “nearly seamless LCD video wall installations.”
Planar and Leyard also introduced the Clarity Matrix ColorBalance, a color matching tool co-developed with Portrait Displays. Designed specifically for Clarity Matrix LCD video walls, Clarity Matrix ColorBalance “makes it easy to achieve consistent color and brightness across the entire video wall,” according to the Planar and Leyard press release.
“Together, these innovations extend Planar and Leyard’s existing Clarity Matrix family, which offers the most comprehensive LCD video wall line-up in the industry – along with superior performance, mission-critical reliability and simple installation and service,” according to the announcement.
Here’s more about the new additions to the Clarity Matrix video wall line:
“With the addition of these two new extreme narrow bezel models, our customers will have more options for deploying the smallest bezel available in the industry, enabling them to build LCD video walls that are nearly seamless,” said Steve Seminario, VP of product marketing at Planar and Leyard. “And with Clarity Matrix ColorBalance, they now have the ability to create the most visually attractive LCD video walls on the market for a wide range of applications where image quality matters, from control rooms and corporate environments to stunning brand advertising.”
Half the Bezel Width of Previous Models
Available in 46-inch and 55-inch sizes, the new Clarity Matrix MX46HDX and Clarity Matrix LX55HDX models offer a tiled bezel width of 1.7 mm, half the size of previous-generation models, allowing for a near-seamless digital canvas that meets today’s sophisticated video wall requirements.
The Clarity Matrix MX46HDX is an ideal solution for customers who want the narrowest bezel available but need a smaller 46-inch display due to space constraints. The Clarity Matrix MX46HDX offers the highest in pixel density of all Clarity Matrix models and is optimal for applications with a close viewing distance or touch interactivity.
The 500-nit brightness Clarity Matrix LX55HDX offers high performance, 24×7 reliability and easy installation – at a lower price point than Clarity Matrix MX models. It is an ideal video wall solution for indoor environments with controlled ambient light such as surveillance and security command centers.
Both Clarity Matrix models are integrated with the Planar EasyAxis Mounting System, which is optimized for extremely narrow bezel widths and offers perfect panel-to-panel alignment. The displays also have an installed depth of less than 3.6 inches, making them compliant with the Americans with Disabilities Act (ADA) for protruding objects.
Planar ERO (Extended Ruggedness and Optics) technology is available as an option, providing an optically-bonded glass front that increases the ruggedness and optical performance of these displays in high-traffic and interactive touch environments.
Precise Color Matching
Planar and Leyard partnered with Portrait Displays to deliver Clarity Matrix ColorBalance, which offers users a fast and accurate way to match individual LCD displays that make up a Clarity Matrix video wall. With Clarity Matrix ColorBalance, installers obtain an automated way to calibrate color and brightness, saving time and reducing the complexity of performing manual calibrations. The tool also includes validation and reporting capabilities for installers to leave with clients.
Clarity Matrix MX46HDX and Clarity Matrix LX55HDX join the Clarity Matrix MX55HDX, which also has a tiled bezel width of 1.7 mm and began shipping in Fall 2016. The new models will begin shipping in calendar Q1 2017 through Planar and Leyard’s worldwide network of authorized resellers.
Integrated compatibility with Shure’s Microflex Advance series of array microphones has been provided with the release of the latest addition to Biamp’s Tesira family, TesiraForté Dan. Released at ISE 2017, the new range of audio processors are able to interact with Shure’s MXA beamforming line of microphones, while also delivering seamless interoperability between DSP and microphone technologies thanks to dedicated Shure MXA input blocks included with the Tesira 3.0 software, reportedly reducing setup and installation times, while offering a complete digital solution.
Four fixed I/O models are offered as part of the TesiraForté Dan range, mirroring the existing TesiraForté family with AI, CI, TI and VI versions, all of which feature 12 mic/line inputs, eight line outputs, Ethernet control, RS-232, up to eight channels of configurable USB audio, four general purpose I/Os and an OLED display as standard. TesiraForté Dan also sees the addition of 32×32 audio channels by way of the Dante Brooklyn II module.
The VI, TI and CI models include Biamp’s AEC technology, designed to remove acoustic echoes and feedback. The devices can be controlled centrally or remotely via Tesira software and users are able to connect natively and directly to Shure systems, such as the MXA910 ceiling microphone.
The TesiraForté Dan processor can network with other units in the range as well as with a Tesira Server IO, should it contain a Dan-1 card. This allows servers to pass audio across an ecosystem, configuring via a Dante Controller.
LG kicked off the busiest day for CES 2017 announcements by revealing its latest OLED TV. While Samsung and Panasonic concentrated on color reproduction with their new OLED announcements, LG preferred to let thickness and features do the talking. LG’s new 4K HDR OLED TV is just 2.57mm thick and, what’s more, there’s Dolby Vision and Dolby Atmos built-in.
The new W7 comes in both 65-inch and 77-inch sizes and is designed to look like a ‘picture on the wall’ rather than a TV thanks to the same super thin design we previously saw with the B7 and C7 series LG TVs. As in LG’s older OLEDs, the W7 also features pixel dimming tech to render blacks with a limitless contrast ratio but the new model also has an expanded color gamut.
The What: Christie has added the Extreme Series to its Aspect family of LCD video wall panels. The new series consists of four models: FHD553-XE, FHD553-XE-R, FHD553-XE-H, and FHD553-XE-HR, and includes a range of brightness levels and features an advanced electronics platform with an optional redundant remote power supply.
