Here are some audio and video trends for 2018.
Buying headphones in 2018 is going to be a fragmented mess because of a silent goodbye to the 3.5mm audio plug, Majority of new headphones introduced at CES were wireless and there are several different wireless systems. Bluetooth audio has historically sacrificed sound quality for convenience relative to a wired connection. However, there are a couple of standards now that promise “better-than-CD” audio quality. For wired connections where we once had the solid reliability of a 3.5mm analog connector working with any jack shaped to receive it, there’s now a divergence of digital alternatives:Lightning, USB-C, and Sony’s 4.4mm Pentaconn connector.
Voice, connectivity and AI took center stage at the Consumer Electronics Show. Alexa Skills and the Voice Experience is really getting off. With over 15 million Amazon Echo devices shipped and 244 million projected by 2022 it is expected to take lead with Google Home Assistant and Apple Homepod with Siri following. Also Google Assistant was mentioned a lot in CES. Google Sold 6.75 Million ‘Google Home’ Devices In the Last 80 Days. ‘Language assistants were a big topic at this year’s CES. More and more manufacturers like JBL and Creative are integrating smart helpers into their WLAN speakers. Alexa support comes to 2018 TVs from Sony, Hisense and LG. Google launches smart displays with JBL, Lenovo, LG and Sony. There will be also other competitors aiming to this market, for example “China’s Google,” shouted out most loudly for voice. Microsoft’s Cortana had a crappy CES so it seems that Amazon Alexa will soon arrive on Windows PCs (HP, ASUS, Acer and others). Introducing Single-Chip Solutions for Building Alexa-Enabled Products.Sony launches a bunch of new headphones and adds Google Assistant functionality to the line.
Binaural, ambisonic, spatial, surround, 3D will be talked about. The most accessible exhibitions of this technology are in Youtube VR and Facebook 360, where users can interact with 360º videos that contain spatial audio. AR/VR was hot topic at CES 2018.
Sound bars are popular for compact home theater setups. Traditional home cinema systems with AV receivers and large speaker arsenals are only used by film and sound enthusiasts who sacrifice space in the living room for this purpose.
People listen to four hours of audio content every day. Streaming platforms like Spotify take a big bit of that. Streaming accounts for 41% of music consumption was the 2017’s most jaw dropping statistic. People will also listen a lot of music from YouTube.
Acoustics-based NFC is being pushed to market as it requires only a microphone and speaker, eliminating tags and chips. Chirp and LISNR are two emerging companies facilitating soundwave communication.
Wireless headphones and speakers become more common. Portable loudspeakers without cables are more popular than ever with music listeners. Most popular connection technology is Bluetooth.More and more manufacturers are breaking away from the cable and are showing new models and updates of completely wireless in-ear headphones at the CES 2018.
There is a bit of nostalgia involved: Several traditional technology tries to make come-back in 2018. The traditionalists among the music lovers continue to use records, so new record players keep coming. Cassette tapes making a comeback thanks to young, independent artists. Artists like Justin Bieber, Eminem and Metallica have all put out material on tape recently as a recent blockbuster film “Guardians of the Galaxy” put a hero center stage with a Sony Walkman. Tube amplifiers are back for traditionalist audiophiles that think that tubes can make your music to sound better.
4K video resolution is hot and 8K going to be pushed to market. TV has progressed to the 4K ultra-high-definition stage with its 3,840 × 2,160 pixel resolution. LG Display has made a 65-inch rollable 4K OLED TV. LG displayed 8K OLED TV at CES. Samsung has technology scales the image resolution to a 8K with AI. LG, Panasonic, and TCL put the spotlight on the chips that do the video processing: For the foreseeable future, any advances in image quality will be coming from these chips, not from the displays themselves.
Welcome ATSC 3.0 in USA: In November, the Federal Communications Commission (FCC) issued new rules that will let TV broadcasters adopt the next-generation wireless TV standard designated ATSC 3.0. This new standard defines the specifications for ultra-high-definition (UHD) or 4K over-the-air (OTA) digital TV. But over-the-air is minority in USA as roughly 75% of households pay for their TV reception for cable or satellite distribution.
Home theater headsets have come a long way. AR/VR is hot. Oculus partners with Xiaomi to launch the Oculus Go and Mi VR Standalone.
Wired peripherals and electronics are still a major part of the market. Cabling for AV systems will have new features: a new HDMI standard and how active cables will provide both power and video to consumer devices.
3D cameras are hot. HP’s Z 3D Camera puts Sprout’s scanning power on your PC. Intel’s new cameras add human-like 3D vision to any machine.
When almost all AV products are pushing more and more features, it seems that almost Everything is too complicated for an average Joe.

This is the best conversation about cables that i have seen or read so far, I’ve been reading audio publications for over 30 years since Stereo Review Magazine was a hot selling publication, you remind me of Julian Hirsch who was a long time contributor to many publications and audio critic, he was an electrical engineer and used the scientific approach in all his writings, as an electrical engineer myself I couldn’t agree more with you assertions, thank you for sharing !

Air Jordans make you jump higher? Nah, that’s not true. But Adidas make you jump further.
From a scientific point of view (trust me, I’m an electronics engineer) every wire has an inductance, even if it’s totally straight (see also: right-hand rule). If your amp stands between your speakers it’s basically already half a winding of a coil from the back of the speakers to the back of the amp, right? A magnetic field is forming around every flowing current. The distance between the two wires of one cable also causes inductance and capacitance as in between the two electrodes of a capacitor. The inductance of one metre / yard of cable is a few nanohenry. The smallest available value of coils for crossover networks in speakers is 100 microhenry, so significantly bigger, but there’s a probability for it to have an at least ultra tiny effect.
Unwanted resistance has a bigger effect on woofers: it raises their Q-factor which affects the tuning of the enlosure, especially in bass reflex boxes. The higher the Qts of the woofer the more sensitive the tuning of the bass reflex enclosure is to changes of parameters. This becomes significant for a Qts of about 0.4 or higher, which is even quite a normal value for Qts because those drivers produce the lowest bass. The bass might lose precision or the deepest bass can disappear. An additional resistance of 1 ohm in series with an 8 ohm speaker raises the Qts by 17 %! I admit that resistance mostly consists of the resistance of the crossover coil (on average 0.3 to 0.7 ohm) and the internal resistance of the amp (0.1 to 0.2 ohm). Two metres (6.5 ft) two-wire cable 12AWG has only 0.02 ohm, but thin 20AWG already has 0.13 ohm. Anyway, a good speaker designer should take that into account.
According to my favorite source of knowledge, the German DIY loudspeaker magazine Hobby HiFi, the effect of upgrading the capacitor in the crossover in series with the tweeter is bigger than upgrading the cables. They even say that without upgrading the caps upgrading the cables has no effect. They recommend to invest up to as much money in the whole crossover as all drivers cost together. But I did not verify that myself with a test yet.

Can Lidars Zap Camera Chips?
https://spectrum.ieee.org/cars-that-think/transportation/sensors/keeping-lidars-from-zapping-camera-chips
Laser safety rules designed to protect human eyes have shaped the design of automotive lidars. Safety rules limit the current generation of lidars—those emitting invisible infrared light near 900 nanometers—to pulse powers so low they limit their measurement range to 60 or 100 meters,
Moving to a longer wavelength that does not penetrate the human eye allows new lidars to fire more powerful pulses and stretch their range beyond 200 meters, far enough for stopping faster cars. Now a claim of lidar damage to the charge-coupled-device (CCD) sensor on a photographer’s electronic camera has raised concern that new eye-safe long-wavelength lidars might endanger electronic eyes.

Air Knife Keeps GoPro Lens Clean In Messy Environments
https://hackaday.com/2019/01/27/air-knife-keeps-gopro-lens-clean-in-messy-environments/
Before the GoPro, shooting video of messy, fast-paced, or dangerous things was very different. There were commercial sports camera rigs and various industrial solutions, but the GoPro, with its waterproof housings and diminutive size, was the revolutionary, stick-it-anywhere camera. Despite this, the team at [tarkka] were having issues with the lens getting covered in coolant while shooting videos of their CNC machining projects. To solve this, they created an air knife to clean the lens.

The Levitating Turntable – What Magic Is This?
https://www.youtube.com/watch?v=JUlPN2A_r-g
Maglev Audio – https://www.maglevaudio.com/
Comments:
Looks cool, it likely sounds poor. Movement in the platter is insane. It’s like a crazy warped record on speed. No way to get solid tracking force probably. Neat, but a gimmick. And a pricey one at that.
Snazzy Labs we don’t want to hear the truth, it looks cool.
Not to mention the impracticalities that were nicely edited out, setup duration, swap times, what happens if you accidentally bump it and have to reset.
unboxes a high end turntable, plays music that sounds like the record is skipping and has speed issues.
If you weren’t convinced that people who spend crazy amounts of money on audio equipment aren’t actually audiophiles. But are in fact audio-snobs. Just looking at the wow and flutter from this $3,000 turntable. I can guarantee that a $450 Audio-Technica LP1240-USB turntable is going to sound better.
No. A “real audiophile” uses music to listen to the equipment
I am positive minded about all innovative designs ideas etc, as far as there is some improvement. But this is over the whole line ridiculous… Look clear to the video, the plate don’t keep the axis and level, which means that the needle is pushed and pulled horizontal and vertical. (this is btw how the needle pick up the signal from both grooves). You are supposed to keep it as stable as possible. The huge magnetic field required to keep the plate at level should not interfere with the extreme sensitive magnetic needle… Maybe they were clever enough to use a frequency far above the audible limit (20 Khz) but what about the harmonics? All high end turntables use mass to make all as stable as possible, 100 Kg for the Thorens reference and up to 600 kg for some “exotics”. A liquid mercury bath to keep it flat etc…. here they use the technology to make it levitate (weight =zero) It’s the most beautiful, and I guess overpriced, turntable to be an absolute piece of crap.
…and then there’s a power cut. Fetch the frisby Fido! Man, what a badly machined platter. What wobble. Wow and flutter be damned, it’s a cheap copy of someone else’s well engineered turntable that sells for REAL high-end costs, as in 20,000 Dollars. Not some cheapo 2900 Dollar rip-off like this.
I have no idea if this thing is well made or a good concept. However, it took me 30 seconds to google and see that it uses capacitors to store enough energy in the event of a power outage to lift the arm and raise the support feet.

In this paper, we study the economic impact of piracy on the supply chain of information goods. When information goods are sold to consumers via a retailer, in certain situations, a moderate level of piracy seems to have a surprising positive impact on the profits of the manufacturer and the retailer while, at the same time, enhancing consumer welfare. Such a “win–win–win” situation is not only good for the supply chain, but is also beneficial for the overall economy.

Ultraviolet Cloud Movie Locker to Shut Down (EXCLUSIVE)
https://variety.com/2019/digital/news/ultraviolet-shutting-down-1203123898/
Ultraviolet, a cloud movie locker once hailed as Hollywood’s best bet to get consumers hooked on digital movies, is shuttering. The Digital Entertainment Content Ecosystem (DECE), the industry consortium that has been tasked with running Ultraviolet, will shut down the service on July 31.
DECE president Wendy Aylsworth told Variety in an exclusive interview this week that the decision to discontinue Ultraviolet was a response to the evolution of the market for online entertainment. “The marketplace for collecting entertainment content was very small when Ultraviolet started,”
Since then, services had become more comprehensive
Ultraviolet launched in 2011 with support from all of the major Hollywood studios except Disney. The service also had buy-in from Lionsgate and other independent studios, and struck partnerships with online retailers
Ultraviolet currently has more than 30 million users, who collectively store more than 300 million movies and TV shows in their cloud libraries.
Disney’s decision to instead develop its own cloud locker service, dubbed Disney Movies Anywhere, long represented a major roadblock for Ultraviolet.

Jos alat toimia kaupallisesti, niin tekemäsi laitteet pitää varustaa CE-merkillä ja sinun valmistajana pitää mennä takuuseen,
että ne täyttävät sähköturvallisuusvaatimukset, ja myös vaatimukset EMC:n osalta.
Tämä jälkimmäinen ei putkivehkeissä muodosta ongelmaa, mutta sähköturvallisuuspuoleen pitää suhtautua vakavasti.
