As the saying goes, the British’s home is his castle, and the management of property requires attention and attention to details. In the northeast of England, one of the companies responsible for this work is the 13th Group, a landlord and housing developer that provides rental and sale of houses. From North Tyneside to York, 13 companies have more than 1,500 employees and serve 70,000 customers in 34,000 properties. Thirteen Group was previously distributed in three offices and hopes to implement modern workplace technology in its new flagship three-story office in Middlesbrough to maximize desk management and meeting space.
System integrator Visavvi is responsible for providing complete audiovisual consulting services in a proof-of-concept way. The reason why he succeeded in winning this job was because he successfully completed the previous installation for the customer. The initial brief was to establish a comprehensive visitor management system with desk and room reservation functions, and was equipped with multiple meeting, collaboration and open desk spaces.
The final facility provides a modern workplace environment, which includes seven standard meeting rooms, two larger meeting rooms/demonstration spaces, collaboration areas using UC&C technology, 357 desks, 11 meeting room reservation panels, and The UK's first equipment management system for GoBright interactive workplace monitoring and installation. The technology used by Visavvi has reduced the number of Thirteen desks by nearly 150, saving a lot of space and money.
Due to the renovation project, it is impossible to actually see these spaces, so the initial consultation of Visavvi was only based on the site plan and floor plan. Visavvi account manager John Andrews said that the housing industry is not an industry that you will naturally associate with new and innovative technologies, but the thirteenth is to push the limits. "It is very interested in the most advanced equipment, which is a surprise for us. They have a very strong idea in their minds, how they want the equipment to work, and how the room works." The technology must be easy to use and must Has a large number of collaboration and video conferencing functions (provided by Microsoft Teams). "Since the pandemic began, this has obviously worked for them, but the main reason is room utilization," Andrews added. "Customers want to see real-time information on the usage of the room, and the room is equipped with sensors to see who is in it, how to use them, and they want a bookable desk."
When visitors enter, they will cleverly use AV to meet them for the first time on the building. Visitors record their arrival on a 10-inch interactive screen managed by GoBright, which will automatically take their photo and then print it as their visitor badge with photo ID. Then, the system sends them via e-mail to the host where it arrived. There is also a reception desk at the back, which can be used by visitors if there is a problem, but with this screen, the receptionist can complete other tasks during the day.
Then, the LG 55 embedded system-on-chip display is used to guide visitors and staff around the building through a series of strategically placed Signagelive wayfinding systems. These display real-time room and table usage information, so that staff and visitors can easily and quickly find their desired destination or free work space.
Downstairs is where visitors can find one of the two larger spaces in the Dockside room. The room can be divided into two parts by a partition, with an 86-inch Visavvi commercial screen display in the center, and two 55-inch Visavvi relay screens on both sides. The AV in the room is controlled by the AMX Modero touch screen. Lenovo ThinkSmart Hub 500 provides an 11-inch touch screen meeting interface for Microsoft Teams, which can start a video meeting with just one touch. Wireless collaboration is provided by Barco Clickshare. Audio in the Dockside conference room is processed through Extron amplifiers and suspended speakers, Ampetronic conference microphones, Beyerdynamic lavalier microphones and Biamp Devio ceiling microphones.
The two standard conference rooms on the ground floor have the same combination of AMX, Barco, Extron and Lenovo technologies, in addition to Polycom Studio, a soundbar with a built-in HD camera and a Polycom Trio conference phone. Two other collaboration areas can be found on the ground floor, one with a Visavvi 43-inch screen and Barco Clickshare, and the other with a 65-inch Avocor W6555 Windows interactive display.
There are also two collaboration areas and two standard meeting rooms on the first floor. There are three standard meeting rooms, three collaboration areas and one meeting room on the second floor. The technology in the conference room is similar to that in the Dockside room. The standard meeting room can accommodate 6-8 people, the meeting room and Dockside meeting room can accommodate up to 20 people, and the Dockside meeting room can accommodate up to 40-50 people.
The core of this installation is the GoBright workplace monitoring and management system. It can be found in interactive map search kiosks spread over three floors. Staff can use these search kiosks to select a desk to sit at or find free meeting rooms, and then book these meeting rooms. Visavvi was originally proposed by British distributor Ascentae as a solution to Thirteen's specific requirements, and was tested with the help of distributors before showing it to customers. In order to stamp the technology, several members of the 13th Group were taken to GoBright's Dutch headquarters to fully demonstrate what the technology can provide. Andrews said: "We didn't press this button until the customer returned from that visit."
Once a decision is made, Visavvi must install and start and run the GoBright system, and one particular aspect posed one of the most severe challenges for the project. "We want to set up 357 desktop systems. We have to put the desktop sensors in each desktop into a hole under the table, connect them all together, and then put them on the USB power input. We found that we can Two engineers complete the 50-day mission every day.” Andrews added.
Each meeting room has a battery-powered room sensor to measure whether the room is empty, and a sensor under each table to measure whether someone is sitting there. The sensor is set to not move for 15 minutes to allow the toilet to rest; if the table is idle for more than 15 minutes, it will be released back to the swimming pool for other people to use. The meeting room works in the same way. If there is no one in the meeting room within the first 10 minutes after booking, it will be released. Alerts will be sent to the facility manager to monitor when the room is not being used and who has booked the room.
Andrews said that although the installation was completed before the full implementation of Covid-19 restrictions in the UK, the system was outdated and could guarantee the return of employees. "When you leave the booked desk, the sensor will turn purple, indicating that it needs to be cleaned. After cleaning, the cleaner (using an RFID card) will wipe it, and then it will turn green again, ready for cleaning.
Was booked again. "Other Covid-related amendments that have been implemented include Barco Clickshare, instead of a dongle that everyone goes through. Employees have already downloaded the app, and employees can also activate Teams meetings using their phones, so they can start meetings without using the touch screen . Meeting. Outside each meeting room is a small touch screen to show when the meeting room is available. When the staff walks over to book a room, they can swipe an RFID card.
Normally, construction delays shortened Visavvi's on-site time than originally planned, but the entire project was successfully delivered within a tight time frame. In the future, the AV will be handled by the internal IT team, while the FM team can modify and adapt to the changing requirements in the data provided to it by GoBright.

Some distributors and manufacturers claim that the latest Samsung TV update disables HDBaseT, and it is recommended that users temporarily turn off automatic updates.
British
Yesterday, I said on Twitter that Samsung’s latest update (v1160) for connected TVs is a dog. According to reports, the update prevented some Samsung TVs from passing
, Which means that HDMI sources connected to the HDBaseT switch or extender cannot be played.
The affected TV dimmed.
Tweet said that the new software is said to "have serious incompatibility issues with the HDBaseT chipset used in most HDMI-based CAT5/6 products." "This software version was released on January 25, but it has not been downloaded/installed by many TVs."
caveat:
Samsung monitors connected via the network, especially the new 6000, 7000 and 8000 series.
The message continues:
The current Samsung update seems to make it impossible for all HDMI inputs on these TVs to connect to any device using the HDBaseT chipset, nor to receive pictures from any device, including video matrices, expel children and splitters. "
It is a technology widely used by Valens Semiconductor to extend the HDMI signal to the long distance of Category 5+ (Ethernet) cables.
The original #LiveInstall Tweet was inspired by
, A manufacturer of HDBaseT switches headquartered in the UK.
Any comments will be welcome

— #LiveInstall (@LiveInstall)
At this point, it is difficult to tell who has been affected by Samsung's so-called bad update. Some traders commented on Twitter that they have seen the problem since the update. Others reported no problems.
Chris Pinder, the founder of A/V exchange company HDanywhere, "confirmed" the interruption in a tweet.
The HDBaseT Alliance released "No problems found. With Samsung-check, will update."
Electric Orange, a UK-based integrator, mentioned at least one customer affected by this update:
Just ask my client to turn off automatic updates. It seems it is too late. The TV is not working!
-Electric Orange (@elecorange)
Several people commented that the video works normally in 1080p, but it does not work in 4K mode.
Use the completed second test
With Sam 4K BD, it can be played at 1080p, but it cannot be played at 2160p. For Panasonic’s 2160p, there is no problem at all.
-Nick (@Cooperboy76)
Nick’s above assessment seems to have resonated with other dealers and suppliers, who suggested temporarily reducing its resolution to 1080p.
Samsung seems to have multiple parties in contact with them, and Samsung has not publicly commented on the so-called "snafu". CE Pro is also being promoted.
Phil Davis, the head of Blustream, told CE Pro that this is not a false warning: "We are very sure of this problem and heard that Samsung is working hard to fix it. Our dealer has a basic point-to-point kit that can be used. No one knows the exact problem. , But we know that the latest firmware on the TV has eliminated HDBaseT compatibility."
The company issued this alert to the distributor:
Samsung firmware update will affect 6, 7 and 8 series screens. On most Samsung screens, the "Auto Update" feature is enabled at the factory, which means that as long as the screen can access the Internet, they will update to that firmware version and then stop working. It is strongly recommended to turn off the automatic update function from the settings menu on the Samsung screen. Please see the screenshots of the automatic update function in the 8 series screens below.
It has just been discovered that the software update (version 1160) of Samsung TV has serious incompatibility problems with the HDBaseT chipset used in most HDMI-based CAT5/6 products. This software version was released on January 25, 2017. The software version has been released to their 6000, 7000 and 8000 series TVs.
The current update by Samsung seems to make it impossible for all HDMI inputs on these TVs to connect to any device using the HDBaseT chipset (including video matrix, expansion kit and splitter), nor to receive pictures from any device. This will obviously affect many manufacturers, including Wyrestorm, CYP, Blustream, HDAnywhere, etc.
If you have any affected customers, please follow the steps below:
1. Turn off the Samsung TV
2. Turn off the broadband router to prevent the TV from connecting to the Internet when it is turned on
3. Turn the TV back on
4. Follow the excerpt from the user manual in the attachment to browse to the "Auto Update" setting, and set this function to "Off"
5. Exit the settings menu on the TV
6. Turn on the broadband router again to re-enable your Internet service
It’s also worth noting that after reading the manual of the 7000 series TV, it pointed out that the automatic update function will be automatically enabled when all Smart Hub terms and conditions are accepted during the TV setup process, so even if you think this function has not been enabled, it will Will be automatically enabled. It might still be.
Martin Ellis, head of HDMI switching company, said: "This is an HDCP timing issue.
, And is a long-term member of the HDMI standard board.
Samsung’s disruptive update is no different from other updates that affect the timing of HDCP, and therefore will disrupt the distribution of the video.
He said: "It will also affect non-HDBT products." "In the UK, it often happens when Sky is connected directly to the TV."
Ellis added that LG’s “HDBT issue shocked us”. "Their 2016 model is not suitable for HDBT. We have to use a workaround."
Ellis said that assuming Samsung "caused" the TV fiasco, the company may launch a solution, but obviously, this is not good for end users and they will blame the audio and video installer. "
At the same time, Pulse Eight is delving into Samsung's problem-the company is working on 6000 and 7000 series TVs-but Ellis believes that the problem is not universal.
In any case, "I am happy to continue to record that we are not affected by the problems in the software version 2.3+."
Ellis said that he was aware of a potential Samsung issue "and we proactively resolved the issue last week and made a silent update to our customers."
He added: “Because we can fix the contents of the kit within a few hours (for example, fix HDCP timing issues), when someone mentioned it to us, we sorted it and silently performed it. Repair, we don’t know anything about it."
At the same time, CE Pro has contacted other suppliers to share their experience.
"My suggestion is that if you want to install a managed system, make sure to manage all aspects of the installation. Disable automatic updates for products that cannot be managed remotely." Ellis said. "When you (the installer) can't control it, letting things update automatically may become the end of the relationship, or make you unable to extricate yourself."
Ellis pointed out that there are many network monitoring services that provide insight into the health of the network and connected devices.
He sighed: "Sadly, all they can usually do is monitor, because the manufacturer does not disclose the management interface. If all suppliers follow the slogan we give installers ultimate control, then the industry can avoid these harmful updates. "
This begs the question: should the installer connect the "smart" TV to the network first?
In response to Samsung’s matter, dealers
This topic is being discussed. An integrator commented:
After successful configuration, if you connect the TV to [Network], you will not be able to truly win. LG's firmware also had problems, which destroyed HDBaseT. Sony has broken IP control in almost every release, and even if it works, not all functions are 100%. Another reason why I never want to watch TV on [network] anymore. Want a streaming media device? …Using Roku, Fire, AppeTV.
The advantages of connectivity include IP control from home automation systems; integration with third-party services (such as Amazon Alexa); and higher quality streaming through TV-based applications.

Daniel Shwartzberg of HDBaseT Alliance talked about the obvious "battle royale" between HDBaseT and AV-over-IP forms, saying that they are unnecessary because they can coexist.
Daniel Shwartzberg of the HDBaseT Alliance discussed HDBaseT and AV-over-IP.
Usually, especially recently,
. Daniel Shwartzberg, director of customer experience at HDBaseT Alliance, said that for many reasons, the competition between HDBaseT and IP over AV is meaningless.
"In terms of convergence and distance, HDBaseT is actually the de facto standard for audiovisual connections. It replaces all the cables used by installers at work. During the installation process, it is replaced with a simple category cable. It can go far, far. It’s larger than the actual capacity of any single cable.” Shwartzberg said in an interview
.
He pointed out that the HDBaseT Alliance has more than 200 members, and
By thousands of people
. He said: "This is a huge success."
"In the past 18 months, there has been a lot of hype,
"In the field of IP-based audiovisual, there are many activities." Shwartzberg said. "In other words, although HDBaseT is its own protocol, IP over AV will of course use standard Ethernet and standard IP protocols to transmit audio or video in the installation."
"You don't have to just do HDBaseT. You don't just need to do AV over IP. It's important to try to understand the use cases in each situation." Shwartzberg said.
Somehow"
He said, "appeared in the market." "It seems that this war is taking place between HDBaseT in one corner and various IP over AV solutions in the other corner."
Shwartzberg added that the problem is not the comparison between apples and apples. "HDBaseT is not AV on IP. When you remember that even AV on IP itself is broken down into many different camps, the confusion becomes even greater. You have 10G. You have 1G. You have from different vendors For different 1G solutions, these vendors themselves don’t know how to work together. There is a lot of confusion."
He said that in the HDBaseT Alliance, IP-based AV and HDBaseT are not "one or the other."
"You don't have to just do HDBaseT. You don't just need to do AV over IP. It's important to try to understand the use cases that apply to each solution."

Thanks for this article. But I completely missed an important question. Battle Royale is not at least IMHO, not between HDBaseT and IP-based AV, but
A) AV as an island
versus
B) AV has been fully integrated into the customer’s common IT infrastructure
As long as the AV is in an island state, for the rest of the earth, it does not matter which technology the AV people use. However, as long as you think of really using the existing infrastructure, rubber will hit the road.
Also, what I found very interesting is that the interoperability between various IP-based AV standards does not seem to be that important. No one seems to care, the solution of manufacturer A is not compatible with manufacturer B at all. why?
Out of all due respect, representatives of the HDbaseT industry group are not effective arbiters in this debate, especially considering that HDbaseT technology is facing obsolescence.
**Full disclosure. I work for the company where the founding member of the SDVoE Alliance works, so this is totally biased**
But... this is like a dispute between coal and clean energy. Of course, they can all provide energy, but one of them is obviously future thinking.
ProAV integrators now need to be proficient in IP. See how video conferencing is converted to IP, and how telecommunications is converted to VoIP. Anyone he had waited for too long was left behind. AV is no different.
The necessary places have been marked
Enterprises have seen the gospel when implementing IP-based AV technology, and integrators have found satisfied customers when installing IP-based AV technology. In this webinar, you will understand exactly why IP-based AV is needed.
This one-hour webinar will discuss the basics of fiber optic cables, how their bandwidth capabilities support current and future AV formats, and the guidelines for specifying and installing fiber optic cable products.

HDBaseT, SDVoE, AVB-For integrators, there is no shortage of AV network paths. Use our research to determine which network AV solution to use.
In terms of audio-visual network and audio-visual distribution, integrators have more choices than ever before.
As far as network AV connection standards are concerned, there is HDBaseT, which allows transmission of uncompressed high-definition AV, power, USB and control via a single cable.
Then there is SDVoE (Software Defined Video over Ethernet), which is a newer technology that can be used for AV distribution via an existing Ethernet network.
Then there is AVB- or audio-video bridging. This technology initially satisfies the need to ensure that audio data packets are delivered in the correct order and to reserve bandwidth for priority routing.
Each standard has its industry supporters, who assert that its specific technology is a technology that can promote the development of the industry now and in the future.
However, for integrators, the most important issue and ultimately the issue that should be informed of their choice is which standard can best meet the needs and budget of their customers.
This is usually not a black or white issue, especially between SDVoE and HDBaseT.
"There are variants of HDBaseT that are very similar to SDVoE," said Paul Zielie, Harman Professional Enterprise Solutions Manager, who taught AVIXA the network AV distribution system.
He said that both standards can "provide a lossless video system so that you can't see the compression effect, so it's very good."
He added that the advantage of HDBaseT lies in its installed user base, which in turn contributes to interoperability between HDBaseT products, backward functional compatibility, and extensive industry expertise for network expansion.
The HDBaseT standard was originally developed by chip manufacturer Valens, and the first specification was finalized in 2010.
In view of its long history, HDBaseT enjoys huge appeal in the audiovisual industry.
This
An industry trade organization with 200 members, all of which are HDBaseT equipment manufacturers certified for interoperability.
As a standard, HDBaseT can transmit ultra-high-definition video and audio up to 328 feet through a single cable.
As Daniel Shwartzberg saw, HDBaseT is a simple, reliable and proven technology that AV integrators can deploy to various commercial implementations.
Shwartzberg, director of customer experience at HDBaseT Alliance, said: "It allows integrators to replace a large number of cables with one cable."
Eliminating dedicated cables simplifies installation, improves cost-effectiveness, and eliminates the need for encoders and decoders.
Shwartzberg said that with HDBaseT, "we are talking about convergence and expansion, all without losing any data."
"There is no compression in HDBaseT-the content that enters one end of the link comes from the other end of the link, and in the middle, we convert it to our own protocol, but this is only used for transmission over Cat-5 cables."
To use HDBaseT, you need to use a matrix switch to switch between different inputs and different outputs.
The scope of implementation can be a simple point-to-point expansion from a single source to a single display, or it can be distributed on a wider network involving multiple inputs and multiple outputs of networked AV.
HDBaseT is non-blocking, and all outputs and all inputs are routed.
In addition, HDBaseT can perform USB and AV distribution at the same time-a typical use case is a conference room system equipped with multiple microphones, noise reduction functions and collaboration software.
Contrary to popular belief, Shwartzberg said that HDBaseT can be controlled, managed and monitored over an IP network.
Customers who already use HDBaseT who want to upgrade or add rooms can do so in the most cost-effective manner by leveraging the existing infrastructure.
Robert D'Addario, president of Cleerline Technology Group, a provider of system cabling and installation solutions, agreed to some extent.
He said: "HD is a great tool for existing infrastructure in the toolbox for installers."
"If you need new cabling during the specification phase of the project, it would be foolish to avoid using optical fiber, and the SDVoE solution allows more options for using optical fiber in current endpoint solutions."
But Shwartzberg touts the number of options for HDBaseT as the main advantage of the technology because it promotes flexibility that other standards cannot currently provide.
He said: "There are too many manufacturers selling interoperable HDBaseT products, so installers can choose."
"They don't have to buy equipment from a particular supplier, they can search for the product that best suits the customer's needs at the price they want to pay."
The promise of SDVoE is obvious in its name: As a ready-made software-defined technology, SDVoE provides "the advantages of the IP infrastructure itself," said Justin Kennington, the company's president.
It is a 40-member non-profit organization responsible for promoting the concept of “audiovisual distribution traffic should move on the IT network”.
Kennington said, in fact, such systems have greater flexibility and scalability, "over time, they can grow with the growth of business needs."
By networking AV and IT-eliminating a separate network-costs are reduced.
He explained: "You have only one network, one infrastructure for design and deployment, maintenance and management."
Zielie said that as a relatively new object, SDVoE is not as widely deployed as HDBaseT, but "it is a good successor to the same types of applications used by HDBaseT."
However, he did list some restrictions related to Ethernet. "With SDVoe and any online media where you use more than 50% of the pipeline, you must first unsubscribe the video you are receiving, and then subscribe to the next one, otherwise the pipeline will overflow."
Zielie said that if the integrator wants to use SDVoE on multiple switches or multiple WANs, it is possible, although there are many ideas for specific use cases.
He said: "SDVoE is a great technology for large frame switchers, but it is actually not very well applied to enterprise networks." "SDVoE will not be suitable for the topology of IP networks."
According to Kennsington, SDVoE does provide flexibility. He believes that the architecture of the SDVoE system is "super simple", "each video source has an encoder, each video display has a decoder, and the middle is the network."
No matrix switch is required.
Moreover, whether it is a meeting room, a digital operating room, a stadium, etc., the architecture of each system implementation remains unchanged.
"If you continue to grow, you may want to add some hardware, but from a basic point of view, you can decide what functions you need-expansion and switching, video scaling or other video processing (such as video walls) without having to buy these Each of the functions requires a specific piece of hardware." Kennington said.
"It's just that the software is different." What determines the function of the SDVoE system is to change the software, not to buy, move or add basic hardware.
Karl Johnson, senior product manager at Christie Digital, recently developed an SDVoE-based system for customers and pointed out that the integration of functions is an important advantage.
He said: "You don't need to buy a multi-viewer and a large number of receivers, you can upgrade and add a multi-viewer to monitor signal sources and combine them."
As a founding member of the SDVoE Alliance, Christie Digital is promoting the market for SDVoE-compliant devices. Recently, the company launched its Terra product, which supports the end-to-end delivery of 4K uncompressed video over 10G Ethernet.
Johnson believes that the ability of SDVoE to combine functions will actually become the "killer application" of the technology, thereby promoting its adoption.
As a relatively new standard, the adoption of SDVoE still provides a learning curve for integrators and even their customers.
D'Addario said that integrators need to "have a lot of experience and knowledge in video and audio networks in order to maximize the potential of SDVoE."
From the customer's point of view, SDVoE can represent a different way of AV processing.
Kennington said: "For two decades, discussions on the integration of network audio and video and IT have been going on, and now SDVoE is here."
"AV and IT staff will need to work together when designing the system, and AV need to understand how to manage bandwidth and pay attention to the security of devices on the Ethernet."
Although those who advocate HDBaseT and SDVoE seem to admit that each standard has its own unique advantages, audio-video bridging is not the case. Audio-video bridging is generally not regarded as an audio-centric standard because it cannot solve the urgency. Customer issues to distinguish yourself.
In essence, AVB is concerned with ensuring that audio and video are delivered simultaneously.
Kennington said: "AVB uses two IEEE protocols to ensure that the signal is correctly timed or at least arrives in a way that is easy to correct."
The second aspect of AVB-it has a route reservation protocol to ensure that the network will find a path to ensure that bandwidth is blocked for priority communication. With these attributes, AVB can provide accuracy that cannot be achieved by other standards.
He said: "The challenge of AVB is that it can be used with the IEEE protocol only if your network switch supports the IEEE protocol."
Kennington added that in most cases, the AV side of the house is unlikely to specify the switch to be used on the Ethernet.
He said: "The IT director doesn't want to unplug all Cisco switches, but replace them with AVB-enabled switches."
If more AVB-compliant products are available, this situation may be different. Shwartzberg of the HDBaseT Alliance says he doesn't know many vendors in the AVB market.
German speaker and amplifier manufacturers are one such supplier.
. Henning Kaltheuner, the company's head of business development and market intelligence, said that AVB provides enhanced features designed to address "serious limitations of conventional Ethernet."
Kaltheuner said that although Ethernet is the ubiquitous AV network technology, it is "not deterministic-the arrival of data packets cannot be determined or guaranteed."
This is just a shortcoming that AVB aims to solve. He said: "AVB is very suitable for use in AV equipment where timing is critical, and requires extremely high reliability without dropping the line," he said.
Think of a large concert venue with many speaker systems and multiple amplifiers.
"If these systems are in the same room or display the same media, they must behave as one system," Kaltheuner explained.
Kaltheuner participated
, A group of manufacturers will further promote AVB for use in professional AV and other industries by creating interoperable open standards for low-latency, time-synchronized, and highly reliable networked AV equipment.
Although Kaltheuner admits that AVB deployment for network AV distribution is affected by product shortages, the Avnu Alliance is actively working on this issue. Recently, the alliance announced the development of the Milan network protocol to ensure that devices used for professional media applications can work together.
As a result, Kaltheuner said: "There are different solutions on the market," adding: "As a standard, AVB is the long-term prospect of upgrading Ethernet with products designed for 15 years."
Supporters of any given standard will naturally declare that the standard they support is the best for their network AV client. However, this in turn has caused great confusion among integrators who are looking for the best solution for their customers.
It’s easier to rank the various criteria according to the utility, but the truth is much more subtle. Integrators should evaluate each criterion based on the best use scenario for their customers.
"...They pack the boxes by not looking at what is available in the audiovisual distribution..."
Usually, AVIXA staff lecturer Marcus Yarborough said that integrators will use a standard for a specific project, “They will continue to use it. Although it’s not a problem, they don’t see what it is. It can be distributed through AV.”
As Yarborough has seen, there is not much difference between the standards for most network AV distribution applications.
He said: "Ten percent of the time, there is something in the application that should guide you to use one technology rather than another."
Shwartzberg echoed this view.
He said: "Integrators must correctly understand customer needs. If you understand the technical advantages and customer needs, then you will make the right decision."

Cisco supports AVB, FYI
No need to "unplug those Cisco switches"-Cisco now supports AVB! You may need to upgrade, but if you choose, you can stay with Cisco. Other companies such as Extreme Networks can also make excellent AVB switches.
For video AVB, one thing to consider is that because the AVB firmware automatically configures the switch, the setup and control are very simple. By using AVB with Biamp Systems products, you can install a Dante audio card on one of the Biamp servers, and extract/output the Dante audio stream when AVB audio cannot meet your needs. The best of both worlds!
Not mentioned yet, but what is worth discussing is the ability to send Dante audio through HDBaseT and the difference between HDBaseT and IPBaseT.
According to different application scenarios, HDBaseT, AVOIP, SDVoE, AVB will be a good choice. I personally prefer HDBaseT.
The missing part of this article, or a good reason for another article, is what is the level of support from well-known software companies about these products? Like Final Cut, Adobe Premiere?
The technology should support advanced multi-view and video wall functions, PIP, PAP, advanced audio routing without additional processing hardware, and can be switched instantly without delay. Therefore, the audio/video routing always defined by the software will It is the best choice to maintain this technology. For a longer time, it should also support 1Gig, 2.5Gig, 5Gig, and 10Gig applications, which can be achieved immediately through downgrading and upgrading technologies
The necessary places have been marked
Enterprises have seen the gospel when implementing IP-based AV technology, and integrators have found satisfied customers when installing IP-based AV technology. In this webinar, you will understand exactly why IP-based AV is needed.
This one-hour webinar will discuss the basics of fiber optic cables, how their bandwidth capabilities support current and future AV formats, and the guidelines for specifying and installing fiber optic cable products.
