There’s no doubt that the audio visual industry has proven its ability to survive and thrive in trying times. Global events have facilitated the rapid evolution of audio visual technologies, and these only continue to advance. Here are some audio visual trends for 2022 collected from many sources (click the link colored to text to get to the information source):
Growing consumer demand for audio content: People are listening to all forms of audio content: news, music, podcasts and books. Nielsen reports 75 per cent of people working from home are streaming music every week, with 40 per cent tuning in daily.
Rapid smart speaker adoption: Smart speakers and voice assistants are becoming common home appliances. One-third of U.S. households are equipped with smart speakers and 44 per cent of U.S. adults use voice assistants. Smart speakers let listeners to respond to ads using voice commands. Consumers are rapidly embracing voice to access information, entertain themselves and shop. The ability to instantly answer consumers’ questions and help them solve problems is becoming a key advantage for marketers who lean into audio.
Digital Audio is becoming multi-devices: Historically, digital audio has been widely consumed via mobile devices; it can now also be launched from a variety of new technologies including tablets, connected speakers, TVs and even smart watches.
Prosumer audio: Prosumer audio gear has remained on a steady upward curve over the last few years. With podcasting, live streaming, and at-home work solutions more popular than ever, it’s been a fantastic few years for prosumer audio sales. Their need for reliable, slightly elevated gear to take their content to the next level is proving highly profitable for certain companies.
Content Still Rules: Audiophiles are fiercely loyal to their favorite DJs, hosts, podcasters, artists and stations. As a result, they’re spending more time than ever listening to audio daily. Listeners consume programming on their own terms.
TikTok has caused a seismic shift in the world of content creation, skewing it ever further into a mobile-first industry. To capitalise on the market, more and more mobile-friendly gear is being created, forgoing the need for hundreds of adaptors and plugging straight into AUX, USB-C, or iPhone ports (or working wirelessly).
Many amplifier technologies in use: While classic class AB amplifiers are more and more often replaced with class D amplifier technology, there is still special audiophile markets for class A amplifiers and tube based amplifiers. New technology just coming to the class D amplifiers are GaN-based audio amplifier powered with switch mode power supply. They promise premium audio systems with good sound quality in a small and light format.
Vinyl records: Vinyl is here to stay, it seems, despite all technological advances that would have seemed to threaten it. Vinyl records (and coincidentally, cassette tapes) are selling like hot cakes again. Vinyl sales have been steadily rising for some time, but in 2020 for the first time in 34 years, vinyl has surpassed CD sales.
Streaming has killed CD: CDs sales are continuously and quickly declining thanks to streaming and music flash drives.
The race to wireless zero latency: Companies around the world are racing to find a solution that all but eliminates latency from wireless audio, removing the need for cables in an increasingly space, waste, and aesthetically-conscious world.
Green screens: As events become more hybrid, green screens will play a significant role, enabling speakers to be placed directly in the content becoming part of the message. Green screens are a great cost-effective way to insert branding and infographics, which works perfectly for online events and we will see them become adopted further for conferences. There are also cameras with depth sense features and software that can use pretty many background for green screen type effects without building a real green screen.
Hybrid events: Events have had to embrace the constant mix of who can attend, who can possibly attend and who is not afraid to attend and as such have flipped to hybrid. Although not necessarily an AV trend, hybrid events are unsurprisingly on the increase as people work from home and corporate travel is halted. In those events content needs to be clear and targeted to get the information across efficiently. There is demand for standalone apps that can enhance hybrid events such as Slack, Slido and Survey Monkey.
Touchless Environments: COVID-19 has accelerated the desire for automation and touchless environments from a nice-to-have to a must-have. They minimize the amount that people come into contact with shared surfaces. Following the throes of COVID-19, it appears that touchless building controls are here to stay.
Remote Control And Remote Management: We’re seeing an increase in demand for remote management software that allows one person, or a small group of people, to log into a remote system and review the status of a set of classrooms or meeting spaces. Increasingly in 2022, companies can implement remote monitoring and maintenance for audio visual systems to support the advancement of technology. Whether your organization is expansive or small, remote audio visual support teams can significantly reduce operating costs for your business.
Live Streaming: As more people look to tune into events from home, we’re seeing an increased need for equipment that supports live streaming.
Video Walls: In many commercial spaces, there’s often a need for a large video display. In past years, many spaces have opted for projection screens as opposed to large LCD displays or video walls, solely because the cost was much lower. The price of video walls getting close to similar to a projection screen, and the benefits almost always outweigh the slightly higher cost.
Service And Maintenance: As more commercial spaces look for ways to save, there’s been an increasing demand for AV integrators to handle service and maintenance in order to maximize the lifespan of AV products. Businesses are focussing on reducing the overhead costs associated with maintaining and installing the equipment. Companies having expertise in sectors other than AV cannot have a dedicated team to manage and monitor their AV equipment.
Snake oil: Many audiophiles are infected by the snake oil curse, which causes them to chase endlessly after what is supposedly better sound reproduction. Audio interconnect and speaker cables have become a profitable business built on imaginative marketing and misinformation. This market now extends into power cords, HDMI, and optical cables. Untold sums of money have been wasted on the fanciful claims of cable vendors. There is lots of ridiculous pieces of pseudo-audiophile nonsense out there. Try to avoid this bullshit in 2022. Try to to restore peace of mind, and the enjoyment of music.
Hybrid environment: Although some employees are returning to the office, it is doubtful that society will return to an entirely on-site work environment. Remote workspaces from 2020-21 on will now be ‘Hybrid’ (home and office). AV technologies are playing a crucial role in creating a modern working environment. Hybrid technologies are changing their form, we had just a Skype call before the pandemic and now we have Zoom, Microsoft Team Rooms, Google Meet, etc with more advanced features allowing space for seamless collaboration and communication. Hybrid environments are expected to go beyond that with continuous innovation and development. Remote employees, distant customers, healthcare providers, and educational institutions can utilize unified communication solutions. It is now increasingly important to adopt technologies that make collaboration easier. At one time, frequent video communications, online learning, and compact hardware design were ambitious audio visual innovations that were hard for people to imagine. Today, they’re top priorities for business, educational, and religious spaces of all types, and are critical to how people interact in those spaces.
Silent Video Gains Momentum: It’s estimated that 85% of short videos viewed on Facebook are watched without sound. Yet as much as 41% of video would be incomprehensible to viewers without sound. Video marketers are using captions, context and other “no-audio” tactics to convey information.
Social Media Goes Video-First: video content is one of the internet’s main attractions. Users are being drawn to video-first platforms. One of the most common reasons people use social media is to view video. But with video streaming set to be as much as 82% of total web traffic by 2022, the importance of video content to marketing strategy is massive and still growing.
Digital audio: Digital audio consumption accelerated in 2021 and commercial engagement followed the audiences. In 2022 we foresee three key commercial trends in the digital audio space: Data-led targeting capabilities provide a powerful way to get advertising cut through, Creativity is a constant rather than a ‘trend’ in advertising and Audience Growth is attracting new advertisers. Programmatic audio is divided into three main supply sources – music streaming (through suppliers like Spotify), podcasts (the biggest opportunity for brands), and online broadcast radio (now more attractive with the addition of data overlay opportunities). Amongst these audio heavyweights we can see emerging innovation in the form of conversational and actionable audio ads.
Virtual and Augmented Reality: Although virtual and augmented reality first entered the public consciousness via video games or social media filters, they are now infiltrating every aspect of our lives. Given the rapid evolution of technology, it is inevitable that these advancements will impact the audio visual industry. Companies specializing in the development of VR and AR technologies are noticing an increase in interest from educational institutions wishing to create an enhanced learning experience. Within the healthcare sector, VR solutions are assisting healthcare professionals with socializing medically isolated patients. Virtual reality has been in development within the audio visual industry for many years. In 2022, virtual reality is becoming mainstream. Or at least tries.
Shift from linear TV to streaming: Video streaming goes beyond traditional TV viewing for people under 45. The lion’s share of viewing by those over 45 is still grabbed by linear television.

https://www.techradar.com/televisions/home-theater/i-tested-blu-ray-vs-netflix-and-disney-plus-on-the-same-movies-and-the-biggest-difference-surprised-me
Smart TVs and streaming devices give access to apps such as Netflix, Prime Video, Disney Plus and more, meaning people can watch millions of hours of movies and TV shows, in up to 4K, for set monthly fees, which ends up being significantly cheaper, and tidier, than buying hundreds of Blu-rays.
So it begs the question: why would people bother with physical media such as 4K Blu-ray anymore? As someone with experience in AV retail and now a tester of TVs, I knew there was a quality difference so I decided to check it out for myself and the results were surprising.
In John Wick 4, both Blu-ray and Prime Video looked great, but on Blu-ray (right) there are deeper black levels and stronger colors. In comparison, the Prime Video version (left) is brighter.
Moving on to Godzilla vs Kong, again in 1080p HD on Netflix vs standard Blu-ray, and it was the same story. The Netflix version looked better than I expected, carrying a lot of the vivid, colorful punch on the neon signs in Tokyo that was on the Blu-ray version but again the Blu-ray version showed deeper black levels and more refined details and textures. I was still, however, impressed with how good the streaming version looked.
Finally, I managed to test a 4K Blu-ray vs a 4K stream in the fantastic re-master of Alien, which was on Disney Plus. In both versions, black levels and contrast were superb, capturing the eerie, doom-laden nature of the movie well. Textures were again sharp on both versions. Although there was that little bit more perceived definition in the 4K Blu-ray. Skin tones, for example, looked accurate on both, but more so on the 4K Blu-ray. It is worth noting that the Disney Plus version was in HDR10, whereas the Blu-ray version was in HDR10+, which gave the Blu-ray the perception of a clearer picture.
Whether it was the UB820 or UB154, Blu-ray did indeed have better picture quality overall thanks to 4K upscaling and performance, but the comparison between them and streaming was closer than anticipated.
In John Wick 4, dialogue and surround effects were perfectly clear through the Prime Video stream but when the Blu-ray took over, a whole new level had been unlocked. It was louder, more powerful and more immersive.
Final thoughts
When I put both Blu-ray and streaming in as close to the same conditions as possible, I was pleasantly surprised by just how close the picture quality battle was. Both had excellent details and colors that would make any viewer happy, although for the real movie lover, Blu-ray had the upper hand thanks to better contrast levels, despite streaming offered a suitable alternative.
Ultimately, it’s down to your preference. Streaming offers a more cost effective way to view more movies and TV shows, and saves space on discs around the house. But Blu-ray offers better picture, superior sound and stability (thanks to not having to rely on Wi-Fi). All I know is, I’m going to be buying more Blu-rays in future. Now if I can just find somewhere to put them all…

We tested five ways to find hidden cameras in hotels and house rentals
https://www.youtube.com/watch?v=h77un7ry5bY
Have you ever wondered if you’re being watched?
It’s a feeling that’s creeping in for more travelers, as stories of hidden cameras — in hotel rooms, house rentals, cruise ships, even airplane bathrooms – continue to make headlines.
Spycams were once the stuff of international espionage, with secret agents given cameras resembling pocket watches, matchbooks – even tubes of lipstick.
Pieter Tjia, founder of Singapore tech company OMG Solutions, said that cameras have become smaller and harder to see in the past three years – often hidden in everyday objects such as calculators, diffusers, and water bottles.
But how hard is it to find these cameras? And do devices designed to locate hidden cameras really work?

A DisplayPort Port That You Can Plug HDMI Into
https://www.youtube.com/watch?v=rZpHizpZSPQ
DisplayPort Dual-Mode (DP++) is quite common but it requires a passive adapter. This is taking things one step further.
Displayport has interoperability modes for DVI and HDMI. I didn’t think they were pin compatible but the DP to HDMI and DP to DVI-I adapters are passive. The DisplayPort does all the magic. For DVI-A or VGA Displayport has those analog signals as well where HDMI doesn’t.
DVI and HDMI are electrically identical. Some gfx cards even have the ability to drive sound through their DVI ports if the other end is detected as a HDMI display
https://hackaday.com/2024/03/12/unusual-port-combines-displayport-and-hdmi/
Normally a DP++ port is marked as such, and requires an adapter that works with the DP++ port. What Xi3 did in this case to make regular DP and HDMI connectors work seems to be somewhat of a mystery, with any information on this type of port being rather scarce.
Since DP and HDMI/DVI use a different signaling scheme, normally an active adapter would be required.
One disadvantage of DP++ is that the HDMI signal will be limited to e.g. 1920×1080 @ 120 Hz and 4K only at 30 Hz.
They can push sounds through the DVI port, but they can’t have the DVI logo on them because audio isn’t part of the DVI standard.
I must also add that while DP to HDMI is passive, the other way is not !
DVI only has some minor advantages in how it is backwards compatible with analog. DVI-D is resolution and frequency limited so that is why DisplayPort is superior. DVI standard also doesn’t support audio or networking. DVI has some limitation with end to end encryption for HDCP content. It’s doable but not built into every source.
Tomi Engdahl says:
https://hackaday.com/2024/03/12/unusual-port-combines-displayport-and-hdmi/
With DP++ the DP port can detect when a DVI or HDMI adapter is connected and then transmit DVI/HDMI TMDS signals rather than DP signals. Since DP and HDMI/DVI use a different signaling scheme, normally an active adapter would be required. One disadvantage of DP++ is that the HDMI signal will be limited to e.g. 1920×1080 @ 120 Hz and 4K only at 30 Hz.

Bye Bye Green Screen, Hello Monochromatic Screen
https://hackaday.com/2024/04/09/bye-bye-green-screen-hello-monochromatic-screen/
It’s not uncommon in 2024 to have some form of green background cloth for easy background effects when in a Zoom call or similar. This is a technology TV and film studios have used for decades, and it’s responsible for many of the visual effects we see every day on our screens. But it’s not perfect — its use precludes wearing anything green, and it’s very bad at anything transparent.
Green screens, or chroma key, to give the effect its real name, relies on the background using a colour not present in the main subject of the shot. This can then be detected electronically or in software, and a switch made between shot and inserted background. It’s good at picking out clean edges between green background and subject, but poor at transparency such as a veil or a bottle of water. The Disney effect instead used a background illuminated with monochromatic sodium light behind the subject illuminated with white light, allowing both a background and foreground image to be filmed using two cameras and a dichroic beam splitter. The background image with its black silhouette of the subject could then be used as a photographic stencil when overlaying a background image.

What are Time Base Correctors & WHEN do you need them? (for glitch art)
https://www.youtube.com/watch?v=so7Mk16wGrA
Time Base Correctors (TBC) are devices that make sure you don’t get signal dropout on your non-CRT monitors whenever you’re doing hard analog video signal glitches (for glitch art purposes). In my demo I take a basic dirty mix of two video signals and send the output directly to a CRT TV and a DLP projector to understand how the former handles glitches fine, while the latter drops the signal (shows blue screen of death, searching for new source, etc). Then, one at a time, I put a Sima SFX-9, Panasonic WJ-AVE 7, Roland/Edirol V-8, and a Prime Image TBC/Freeze II in between the dirty mix and the projector to get an idea of how each device stabilizes the video glitch so there’s (ideally) no more signal dropout.
The DLP projector in this demo is simply acting as our example of any display that is NOT an old tube TV monitor, meaning similar signal dropout can occur in other types of displays and capture devices (with varying degrees of severity). BUT, if you’re lucky, some older LCD displays actually do a decent job of not dropping the signal and can handle glitches better by themselves, than if you were to run the signal through a Roland/Edirol or Panasonic mixer first.

Gigabit Multimedia Serial Link
https://en.wikipedia.org/wiki/Gigabit_Multimedia_Serial_Link
Gigabit Multimedia Serial Link, commonly referred to as GMSL, is a serial link technology that is used for video distribution in cars. It was developed by Maxim Integrated. Maxim Integrated was acquired by Analog Devices[1][2] in 2021.
GMSL is an asymmetric, full duplex SerDes technology – which means that it transports data at a high rate in the downlink (or forward) direction, while simultaneously transporting a lower data rate in the uplink (or reverse) direction. It transports power, bidirectional control data, Ethernet, bidirectional audio and multiple streams of unidirectional video[3] simultaneously over a single coaxial cable or shielded twisted pair cable. A GMSL serializer receives video from a standard digital video interface such as HDMI, DisplayPort, Camera Serial Interface (CSI-2) or Display Serial Interface (DSI) over a cable up to 15 meter in length.[4] The data is received by a deserializer that outputs it on another standard digital video interface. GMSL video transport may be unprotected or encrypted using HDCP.[5]

Build Your Own RGB Fill Light For Photography
https://hackaday.com/2024/04/19/build-your-own-rgb-fill-light-for-photography/
Photography is all about light, and capturing it for posterity. As any experienced photographer will tell you, getting the right lighting is key to getting a good shot. To help in that regard, you might like to have a fill light. If you follow [tobychui]’s example, you can build your own!
The build relies on addressable WS2812B LEDs as the core of the design. While they’re not necessarily the fanciest LEDs for balanced light output, they are RGB LEDs, so they can put out a ton of different colors for different stylistic effects. The LEDs are under the command of a Wemos D1, which provides a WiFI connection for wireless control of the light.
