Here are some audio and video trends for 2019:
The global Hi-Fi Systems market was valued at million US$ in 2018 and is expected to grow. EISA Awards has selected Hi-Fi product category winners, but I did not see anything really fancy new innovations that would excite me there. The Hi-Fi speaker market has seen considerable consolidation over the years but is expected to grow. The global Hi-Fi speaker system market is highly competitive. Various established international brands, domestic brands and as well as new entrants form a competitive landscape. The market is expected to have higher growth rate as compared to the previous years due to the booming electronic industry globally. It is due to the rising income of individuals globally and increasing affordability of technology products globally. Due to technological adoption and smart gadgets, North America region is showing steady growth in the Hi-Fi speaker system market. On technology standpoint the Hi-Fi market is mainly based on pretty much stabilized technology as class D amplifiers have been on mainstream for many years.
Smart TVs are everywhere. The vast majority of televisions available today are “smart” TVs, with internet connections, ad placement, and streaming services built in. Despite the added functionality, TV prices are lower than ever. Your new smart TV was so affordable because it is collecting and selling your data. It is clear that TV companies are in a cutthroat business, and that companies like Vizio would have to charge higher prices for hardware if they didn’t run content, advertising, and data businesses. Google wants sensors and cameras in every room of your home to watch, analyze, you, patents show.
Streaming services competition stays high. Apple’s embracing the TV industry for the first time: Vizio and LG TVs will support AirPlay 2 and HomeKit, while Samsung TVs will get an iTunes Movies & TV app, as well as AirPlay 2 support. Google and Amazon are playing are important players on smart speaker markets.
4K video resolution is still as hot as in 2019 – it us becoming mainstream and getting cheaper. Peraso showcases 4K wireless video at CES 2019. LG has produced a market-ready rollable OLED TV. The new 75-inch 4K Micro LED TV announced at CES 2019 proves Samsung is serious about scaling the technology to do battle with OLED. But it seems that even in 1029 “4K” trend remains woefully deficient from a compelling-content-availability standpoint. CES 2019 is already full of weird and wonderful monitors.
But new higher 8K resolution is being pushed to market. The “8K” (resolution) tagline was apparently everywhere at CES this year. Samsung announced a 98-inch 8K TV because why not. LG has come strong to CES 2019 with an 88-inch 8K OLED TV, a 75-inch 8K LED/LCD TV, HDMI 2.1, new auto calibration features, Alexa built in, and many more features. It seems that this ongoing evolution is occurring out of necessity: as a given-size (and -pixel-dense) display becomes a low profit margin commodity, manufacturers need to continually “up-rev” one or both key consumer-attention-grabbing parameters (along with less quantifiable attributes like image quality) in order to remain profitable … assuming they can continue to stimulate sufficient-sized consumer demand in the process. I am not sure if they can stimulate 8K to mass market in next few years.
Wall size TVs are coming. Samsung announced a modular TV at CES. Samsung first showcased this MicroLED TV technology at CES 2018, showcasing how the screens were composed of millions of individual LEDs. Individuals screens could be combined to create massive displays, which the company calls The Wall TV. The wall-sized displays shown in recent years at CES are, in my opinion, quite ridiculous, at least for the masses.
HDMI updates are coming. At present, the HDMI equipment uses the 2.0 standard (adopted in 2013) tht provides support for example for 4K video. HDMI Forum announced a new 2.1 standard already in November 2017, but it just starter showing in CES in January 2019. 8K fiber-optic HDMI cables seen at CES 2019. The 2.1 standard is a big change in technology at the bus bandwidth increases from 18 gigabit to 48 gigabits per second. This enables up to 10K video transmission and up to 120 frames per second.
Bendable displays are really coming to PCs and smart phones. LG’s “rollable” display shown this year neatly showcased the technology’s inherent flexibility while also addressing the question of how to hide a gargantuan display when it’s not in use. Several foldable smart phones have been shown. Chinese company Royole was showing off the FlexPai at CES in Las Vegas.
Micro displays for VR and AR glasses have developed. MicroLED is better looking, more efficient and more versatile than any previous display tech. Now all Samsung, Sony, LG and others have to do is figure out how to manufacture it affordably.Nanoco Technologies and Plessey Semiconductors have partnered to shrink the pixel size of monolithic microLED displays using Nanoco’s cadmium-free quantum-dot (CFQD quantum dots) semiconductor nanoparticle technology. Microchips and organic LEDs that deliver 4K-like high resolution displays a quarter of the size and half the weight of existing virtual reality (VR) headsets have been developed under a European Union project. Marc Andreessen says VR will be “1,000” times bigger than AR even though VR seems to be the popular whipping boy amongst the tech community.
There seems to be no shortage of angst with the current (and unfortunately burgeoning) popularity of usage of the term artificial intelligence (AI). Intelligence has been defined in many ways which makes it hard to get good picture on what is going on. I am still waiting for sensible intelligent AI to do something useful. But the ability for a sufficiently trained deep learning system to pattern-match images, sound samples, computer viruses, network hacking attempts, and the like is both impressive and effective.
Potential problems related to the coming of self-driving car technologies and cameras are expected. A man at CES in Las Vegas says that a car-mounted lidar permanently damaged the sensor in his new $1,998 Sony a7R II mirrorless camera. Man says CES lidar’s laser was so powerful it wrecked his $1,998 camera because the LIDAR laser power rules ensure lasers are safe for human eyes—but not necessarily for cameras. Is this something that camera and car manufacturers need to figure out together?
2019 Will Be the Year of Open Source from software and even hardware. Open source video player app VLC has now reached 3 billions downloads.
When almost all AV products are pushing more and more features, it seems that almost Everything is too complicated for an average Joe.

How Smart Speakers Are Changing the Way We Listen to Music
https://pitchfork.com/features/article/how-smart-speakers-are-changing-the-way-we-listen-to-music/
With everyone from Amazon to will.i.am trying to get us to talk to their speakers, should listeners be excited, or worried?
Almost four years after the Echo and Alexa’s rather inauspicious debut—“The whole thing is a tad baffling, but also intriguing,” wrote TechCrunch at the time—smart speakers are now teetering on omnipresence. Sales tripled between 2016 and 2017, and analysts expect nearly 60 million units will be bought globally this year.

Qualcomm Adds Another Chip to Changing Audio Amplifier Space

Every generation of audio amplifier is designed to pump out louder and clearer sounds. They are also tapped to consume less power and better protect against failures due to high temperatures or mechanical faults. But as the space for audio systems inside speakers, smartphones and other devices shrink, companies ranging from Qualcomm to Texas Instruments have started to plug signal processing directly into amplifier ICs.
Audio amplifiers are designed to boost audio signals while preserving its detail. Today, the audio amplifier space is dominated by digital devices that integrate a number of discrete components that typically surround linear and other analog amplifiers. Many analog chip manufacturers have also started to add DSPs and other ICs to adjust the amplifier’s performance based on feedback from the physical speaker and a stored model of speaker performance.

Why mirrorless cameras are taking over
https://www.youtube.com/watch?v=p5PvHlk3yig
While mirrorless cameras have been rising in popularity since at least 2013, driven in large part by Sony’s A7 and Panasonic’s GH cameras, this past year feels like the start of this camera format becoming dominant. Both Nikon and Canon, the last major manufacturers to avoid the full-frame mirrorless market, released feature-packed cameras complete with radically new designs and lens mounts, and we’ve seen ambitious new models from Fujifilm and Panasonic that bring features not before seen in DSLRs. Traditional DSLRs aren’t going anywhere for a while, but expect to see more and more mirrorless designs from all these companies.
What makes mirrorless cameras unique?
Dropping the SLR mirror means more than you’d think.

Crop Factor TRUTH: Do you need Full Frame?
https://www.youtube.com/watch?v=hi_CkZ0sGAw
The same lens produces different results on cameras with different sized sensors. As a result, it can be tough to cross-shop Micro Four-Thirds, APS-C, Full Frame, and Medium Format cameras.
Crop Factor is a conversion that makes it simple to determine the exact results you’ll get with any given lens, regardless of your camera’s sensor size. By multiplying your camera’s crop factor by a lens’ focal length AND aperture, you can determine the full frame equivalent angle of view, depth-of-field (background blur) and a good estimate of the low-light noise.

The TVs will be equipped with a 5G module as well as a high-end 8K resolution display, sources familiar with the plan told the Nikkei Asian Review. This means they will be able to use the new generation network to download data-heavy content, such as 360 degree videos in which viewers can watch in every direction, and virtual reality programs. There are questions, however, over how soon the wider ecosystem for such services will be available.
Huawei’s first attempt to make TV sets is fueled by a desire to complete its “ecosystem” of consumer electronics — which already includes everything from smartphones to wearable devices — even as analysts voice doubts over the strength of its brand image.

Micro Four-Thirds is DEAD (Picture This! Podcast)
https://www.youtube.com/watch?v=qjXSnNMZ0PU
Many photographers love the Micro Four-thirds mount for its small size and big feature set… But, increasingly, full-frame mirrorless cameras are a similar size and produce undeniably superior results. With Canon and Nikon joining Sony in the full-frame mirrorless market, and Fuji creating value-oriented APS-C cameras, I think it’s inevitable that those lens mounts will lure most new photographers. Additionally, many existing Micro Four-Thirds photographers will be lured to competing camera systems because of the cleaner images, better low-light capabilities, and wider selection of fast lenses. If nothing else, people think full-frame sensors always produce better images, even if that’s not always true.

Finally, A TV For Portrait Videos
https://hackaday.com/2019/05/04/finally-a-tv-for-portrait-videos/
Vertical video is bad, or so we’re told, and you shouldn’t shoot a video with your phone in a vertical position. Why? Because all monitors are wider than they are tall. This conventional wisdom is being challenged by none other than Samsung. There is now a vertical TV engineered specifically videos shot on mobile phones.
“Samsung Electronics analyzed the characteristics of the Millennial generation, which is familiar with mobile content, and presented a new concept TV ‘The Sero’ (loosely translated as ‘The Vertical’), which is based on the vertical screen, unlike the conventional TV,” so goes the press release.
Features of The Sero TV include synchronization between the screen and a mobile device, and mirroring functions based on NFC.
Nevertheless, there actually is a market for ‘vertical’ or portrait displays; thanks to the ever-widening of aspect ratios by LCD manufacturers, it makes sense to edit documents with a vertically-oriented monitor.

Samsung announces the ISOCELL Bright GW1, a 64-megapixel image sensor for mobile phones, expects it to go into mass production in the second half of this year
64-megapixel phone cameras are coming
Samsung fires new salvo in megapixel wars
https://www.theverge.com/2019/5/8/18537699/samsung-64-megapixel-phone-camera-sensor-announced
Samsung has announced a new image sensor for mobile phones with a higher resolution than anything comparable on the market. The ISOCELL Bright GW1 is a 64-megapixel sensor that uses the same 0.8μm-sized pixels as Samsung’s current 48-megapixel component, meaning it’ll be a physically larger sensor that can capture more light overall.
The Bright GW1 will produce 16-megapixel images by merging four pixels into one, like how existing 48-megapixel sensors turn out 12-megapixel photos by default. Samsung’s new sensor will also be able to descramble the color filter for full-resolution 64-megapixel shots in good light. Sony’s IMX586 48-megapixel sensor has a similar capability, but Samsung’s doesn’t; today the Korean company is also announcing an updated 48-megapixel part that offers the same feature.
48-megapixel cameras are now a common sight on phones: Samsung, Huawei, Oppo, Vivo, Xiaomi, and others have all shipped devices with the sensors.

The ‘megapixel wars’ on smartphone cameras stopped some time ago but recently we are seeing an uptick in smartphone image sensor pixel counts, not because consumers demand higher resolution images but because many modern sensors use Quad-Bayer technology which combines four pixels into one, for better detail, lower noise levels and increased dynamic range.

Can You Recover Sound From Images?
https://www.youtube.com/watch?v=eUzB0L0mSCI
Is it possible to reconstruct sound from high-speed video images?
This video was based on research by Dr. Abe Davis and colleagues. I found out about this work years ago and was fascinated by the way he was able to capture vibration information in image-only video. I always imagined the motions of objects would be visible as when recording a tuning fork in slow motion – so deriving sound from high speed images seemed a feasible task. But the reality is much more difficult.
Sound vibrations only cause objects to wiggle by about a micrometer. This is much smaller than a pixel, so the algorithm must understand the characteristics of the image. A move in one direction should cause some pixels to lighten slightly, while others darken – and this behavior is correlated along the edges of the image. So noise can be reduced because it’s random over the image and there are enough places to sample that you can get it to cancel out.

Human Media Lab’s LightBee Drone Can Project Holographic Images
https://blog.hackster.io/human-media-labs-lightbee-drone-can-project-holographic-images-7e1ad4d5c046
“Virtual Reality allows avatars to appear elsewhere in 3D, but they are not physical and cannot move through the physical space. Teleconferencing robots alleviate this issue, but cannot always traverse obstacles. With LightBee, we’re bringing actual holograms to physical robots that are not bound by gravity.” — Roel Vertegaal, HML Director

The diminishing returns of high end audio
https://www.youtube.com/watch?v=a5GN1a5XmTU
Is an audio product costing 4 to 5 times more than another worth the extra money? Are there 4 to 5 times the benefits to be enjoyed for that extra money?
Comments:
the fact that a modest investment gives you 90% of what you can get in sound quality is something Us poor boy have survived on for years. trying now to do better
Unless you have the money, it’s best not to listen to higher end audio gear …. what the ears don’t hear the mind doesn’t miss..! If you are happy with your setup .. leave it !
I take my enjoyment of music very seriously!. When I’m not listening to music, I’m thinking about listening to music! There certainly is point of diminishing returns with audio performance. Many well matched budget products can sound amazing!

Leti Designs GaN MicroLEDs for Smartwatches, TVs
https://www.eetimes.com/document.asp?doc_id=1334708
At Display Week 2019 in San Jose, California, research institute Leti described a new technology for fabricating gallium nitride (GaN) microLED displays on a CMOS process that significantly reduces transfer steps and eliminates the size limit for applications ranging from smartwatches to large televisions.
The new approach fabricates elementary units of all-in-one red, green, and blue (RGB) microLEDs on a complementary metal-oxide-semiconductor (CMOS) driving circuit and transfers the devices to a simple receiving substrate. The units can then be fabricated with a full-semiconductor, wafer-scale approach.

When computer audio is the subject is a laptop adequate for the task or do you need a big high priced computer instead?
