Netflix consumes 15 percent of the world’s internet traffic, according to Sandvine's new Global Internet Phenomena Report - and it could be 3x worse

Netflix consumes 15 percent of the world’s internet traffic, according to Sandvine's new Global Internet Phenomena Report - and it could be 3x worse | pixels and pictures | Scoop.it

Video is taking over the internet, but it's never been more obvious than when you look at who's hogging the world’s internet bandwidth.

Netflix alone consumes a staggering 15 percent of global internet traffic, according to the new Global Internet Phenomena Report by bandwidth management company Sandvine. 

Movie and TV show fans are lapping up so much video content that the category as a whole makes up nearly 58 percent of downstream traffic across the entire internet. The report brings us some truly shocking numbers when it comes to the state of web traffic, too. But, at 15 percent all on it’s own, no single service takes up more bandwidth than Netflix.

What’s perhaps most surprising is that Netflix could dominate even more of the internet’s data if it wasn’t so careful optimizing it’s content. 

According to the study, Netflix could consume even more bandwidth if it didn't so efficiently compress its videos. “Netflix could easily be 3x their current volume," says the report

 

As a case study, Sandvine looked at the file size of the movie Hot Fuzz on multiple streaming services. The file size for this 2 hour film when downloading via iTunes ranged from 1.86GB for standard definition to 4.6GB for high definition. On Amazon Prime, films of a similar length clock in at around 1.5GB. However, the 120 minute film on Netflix only takes up 459MB.

Philippe J DEWOST's insight:

Seems that Netflix's encoding process is up to 3 times more efficient than competition, without apparently consumers noticing.

Are they using NG-Codec ?

Xiaomi launches Android-powered Mi TV 3 with 60-inch 4K display for less than $800

Xiaomi launches Android-powered Mi TV 3 with 60-inch 4K display for less than $800 | pixels and pictures | Scoop.it
Xiaomi, on Monday, unveiled the Mi TV 3, a 60-inch TV with 4K display at a price point of RMB 4,999 ($780). Much like the Mi TV 2 and previous generation television sets from the company, the Mi TV 3 has been launched in the company's home market China.

The Mi TV 3 sports an LG-made 60-inch 4K display with lossless quality, MEMC, and color gamut. The display comes with full aluminum frame running along the sides. At 11.6mm, the Mi TV 3 is pretty sleek too. It is powered by a MStar 6A928 processor consisting of Cortex-A17 and Mali T760 GPU. An 8GB eMMC 5.0 flash is used as the internal storage. The company hasn't revealed any information about the RAM module.

On the connectivity side, there are three HDMI ports, two USB ports, one VGA port, one Ethernet port, one AV in, an output for Subwoofer, and a standard RF Modulator. On the audio front, the Mi TV 3 features Virtual Surround technology, deeper bass, and dialogue enhance tool with auto volume balance support. The company says that acoustics for the TV has been put together by Grammy award winner Luca Bugnardi, and former research head at Philips acoustics Wang Fuyu.

The speaker bar, which sells separately at RMB 999 ($160), is made of four mid-range 2.5-inch subwoofer, and interestingly comes with the main board of the TV. The company says that it has separated the processor board from the screen, as doing this significantly reduces the replacement cost of internal components. This also increases the life cycle of the TV, the company claimed.

Who needs a television four times sharper than HDTV?

Who needs a television four times sharper than HDTV? | pixels and pictures | Scoop.it

At the recent Consumer Electronics Show in Las Vegas, talk of Ultra HD was on everyone’s lips. A handful of Ultra HD sets were even on display. No question, Ultra HD provides stunning images—at least when displaying content created in the new “4K” video format. Unfortunately, 4K content is virtually non-existent.

So far, only a handful of feature films have been shot with cameras capable of 4K, including “The Amazing Spider-Man”, “Prometheus” and “The Girl With the Dragon Tattoo”. That is hardly surprising given the amount of work involved. Insiders reckon making a full-length digital feature in 4K is equivalent to producing six ordinary 2K films.

Even so, some 17,000 cinemas around the world now have digital projectors capable of showing 4K films. So, if and when Hollywood upgrades wholesale to the new video standard, cinema-goers will be able to decide whether 4K is worth the premium they are bound to be charged.

The recent flood of 3D films largely failed that test. The lacklustre sales of 3D television sets suggest they are now doing the same. Will 4K suffer the same fate? It is far too early to say. But, for sure, 4K television—far more than 4K cinema—faces some formidable challenges.

Canon debuts second-gen “Cinema” 4K cameras

Canon debuts second-gen “Cinema” 4K cameras | pixels and pictures | Scoop.it
Two new Canon cameras capture “4K” video — 4096 by 2160 resolution motion imagery that is “emerging as the new standard for advanced effects and post-production in Hollywood,” Canon says. “It is particularly important for big-budget motion pictures that include scenes compositing live-action cinematography with high-resolution computer-generated imagery.”

The EOS-1D C is an SLR camera providing video recording at 4K, as well as Full HD video, and 18-megapixel stills, using a full-frame 24 by 36mm CMOS sensor. 4K video is captured by an approximately APS-H-sized portion of the full image sensor.

The camera records 8-bit 4:2:2 Motion JPEG 4K video to dual CF cards. It has an expanded sensitivity range up to ISO 25600 “for exceptional motion-imaging results with reduced noise even in low-light settings.”

Also, Canon says its Log Gamma enables high-quality video “with rich gradation expression, making possible the type of impressive image quality required in motion pictures by maximizing both highlight and shadow detail retention while also providing a high level of color-grading freedom.”
The 1D C has a headphone jack for audio monitoring, and will be available this year for $15,000.

Welcome to Faroudja Enterprises

Welcome to Faroudja Enterprises | pixels and pictures | Scoop.it

The Faroudja Enterprises founders have realized that their experience in video technology is applicable to video  compression.  The company designs pre-processors and post-processors, used before and after compression coding/decoding, to achieve a lower bit rate and better image quality with existing codecs.

 

THE COMPANY DOES NOT PERFORM COMPRESSION CODING OR DECODING.  THE COMPANY DESIGNS

PRE-PROCESSORS TO BE USED BEFORE COMPRESSION CODING, AND POST-PROCESSORS TO BE USED

AFTER DECODING.

 

A better image quality at the same bit rate may be chosen, or if desirable, a 35% to 50% bit rate reduction for the same image quality as before may be obtained.  In any case, compression artifacts are reduced or eliminated.

 

Significant results have already been achieved:  2 patents have been granted, and 3 more are in the works.  The processes are suited to a wide range of video, from teleconferencing and videophones, to Standard Definition, High Definition and Ultra High Definition applications.

Philippe J DEWOST's insight:

Absolutely delighted to see that Yves Faroudja is back in the video game with a new venture. I have the deepest respect for him and know how he regrets having missed the opportunity to invest in imsense :-)
