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.

Repurposing a HDV camcorder for the home office
https://www.edn.com/repurposing-a-hdv-camcorder-for-the-home-office/?utm_source=edn_facebook&utm_medium=social&utm_campaign=Articles
One downside to any webcam is that, regardless of the embedded image sensor’s native resolution and other characteristics, the lens it’s mated to is inevitably a fixed focal length, and its close-focusing capabilities, not to mention its more general optical attributes, tend to be subpar. The one thing I don’t like much about my green screen is that because of its circular shape, I need to sit quite close to the webcam so that the virtual background’s edges and real-world mess beyond them don’t appear in the footage. A camera with an optical zoom lens would address this issue, and I’m prepping to try just such a setup; stand by for more coverage to come on this topic.
The prior experience I’d recalled was with one of the presenters at the Embedded Vision Summit earlier in the year, who had a similar setup. He was using Open Broadcaster Software (OBS) as his recording platform, which as it turns out supports user-adjustable audio delay for exactly such sync-fixing scenarios. But Zoom, which presumes the use of integrated (or alternatively USB direct-tethered) webcams, isn’t as sophisticated.
The easy fix for that particular meeting was to switch to the camcorder’s integrated stereo electret condenser microphone set; since both the audio and video were now coming from the same source and getting delayed by the same Cam Link 4K adapter, sync was restored.

Google loses Sonos patent case, starts stripping functionality from speakers
Rather than pay royalty fees to Sonos, Google is sending downgrades to customers
https://arstechnica.com/gadgets/2022/01/google-loses-sonos-patent-case-starts-stripping-functionality-from-speakers/
Following a preliminary ruling in August, the US International Trade Commission has issued a final decision saying that Google infringed five Sonos smart speaker patents. It would be possible for this ruling to result in some products like the Nest Audio, Chromecast, and Pixel line being banned in the US, but Google has prepared ITC-approved software downgrades, which remove the infringing features from users’ products.
Sonos essentially invented the connected speaker category for streaming music, but the advent of voice assistants has led to Big Tech stomping all over Sonos’ territory.

Here is a patent from 2001
“Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near ½ Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set.”

How are Images Compressed? [46MB to 4.07MB]
https://www.youtube.com/watch?v=Kv1Hiv3ox8I
You’ve probably saved 1000s of JPEG images, but do you know what exactly JPEG does? Our smartphones and cameras save images in JPEG format, furthermore, the majority of images you see on the internet are saved using JPEG compression. This format is everywhere, but do you know exactly how it works? Well in this video we’re going to explore the JPEG compression format. This is a rather complicated video, so it may take watching it a few times through to understand it all.

How Video Compression Works
https://www.youtube.com/watch?v=QoZ8pccsYo4
Have you ever wondered how video streaming is possible? Let’s think about how big a typical 1080p video is: 1920×1080 pixels, 24-bits each, 30 frames per second… That’s almost 1.5 gigabits per second. How can you transmit that much data, over the air, in real time? The answer is video compression.

GStreamer for your backend services
https://arunraghavan.net/2022/08/gstreamer-for-your-backend-services/
Daily is a real time calling platform as a service. One standard feature that users have come to expect in their calls is the ability to record them, or to stream their conversations to a larger audience. This involves mixing together all the audio/video from each participant and then storing it, or streaming it live via YouTube, Twitch, or any other third-party service.
As you might expect, GStreamer is a good fit for building this kind of functionality, where we consume a bunch of RTP streams, composite/mix them, and then send them out to one or more external services (Amazon’s S3 for recordings and HLS, or a third-party RTMP server).

Avatar 2 Just Dealt A Devastating Blow To Movie Theaters
https://www.giantfreakinrobot.com/ent/avatar-2-devastation-blow-theaters.html
Avatar 2′s paltry movie theater opening left AMC, Cinemark, IMAX, and Disney dropping in prices per share in the stock market.
For some reason, Avatar 2 being released in movie theaters was mentioned in some circles as the “savior of the box office” but current market stock prices for movie theaters have proven that to be untrue. The long-awaited sequel was officially released to a decent box office haul, but nothing impressive enough to confirm that the movie will be a giant money maker. What makes matters worse is that AMC, Cinemark, IMAX, and Disney all saw significant stock market plummets this past weekend.
Avatar 2 might have hit movie theaters this weekend, but AMC saw an 8.26 percent drop yesterday. Cinemark also plummeted 10.3 percent, though it would recover a few points in the trading hours following the drop, and IMAX saw a drop of 5.76 percent. Even Disney, who released the movie, saw a 4.77 percent dip of its own, which now counts as the biggest drop for the company since 2014.
Stock traders seemed to have believed that Avatar 2 would have people running to the movie theaters to watch the sequel, which could possibly rebound some good stock market prices. However, these traders might not have taken into account that it has simply been a bit too long since the first Avatar was released.
People might not care about the story any longer, and the biggest gripe currently is the whopping 3-hour and 12-minute run time, leaving theater turnover time suffering a great deal more.
the biggest talking point of the new movie was the stunning visuals. Those same visuals were echoed in the first movie and seemingly amplified in the sequel
