Samsung 8K QLED TV Uses Artificial Intelligence to Upscale SD Content to 8K Resolution

January 8th, 2018 4 comments

You’ve probably read how artificial intelligence can be applying to modify photos, either repair them, or change the weather in photos from sunny to rainy, and vice versa. Samsung unveiled an 85″ 8K QLED TV right before CES 2018, which should be news by itself, but that I found really intriguing is the TV’s artificial intelligence capabilities that will upscale standard and other resolution content to 8K resolution.

The TV will take SD, Full HD or 4K sources runs it through machine learning algorithm to re-create details, reduce noise, and restore edges to bring them back to 8K picture quality. Not your usual “dumb” upscaling 🙂

The TV is said to be equipped with a database that studies and analyzes millions of images in advance to transform low-resolution content into high-resolution, and capable of selecting the optimal filter to convert the source to higher quality. Samsung then explains the images is processed 64 times (how?) to offer natural images in high resolution, and finally elements of picture quality (black/blooming/brightness) are categorized in the input sources to produce pictures with more detailed contrast.

Samsung’s AI technology can also optimize audio for specific scenes, for example the audio from spectators may be amplified while watching sports events, or low-frequency sounds be highlighted while watching concerts.

This will be interesting to find out how well that works, and if it does we can eventually (i.e. in several years) expect some changes in the way video is streamed. For example, if somehow it becomes possible to obtain 8K quality while streaming SD quality videos, then content providers would then likely send low bitrate SD resolution data to compatible devices, and let them upscale content to 8K or whatever native resolution the TV supports. That seems to good to be true so wait and see. Alternatively (more likely?), this could become a fallback option when network connectivity is not good enough for 8K content.

While Samsung is showcasing an 85″ 8K TV at their event, the company will also launch 65″ and greater 8K QLED “A.I.” TVs in H2 2018. The company also introduced that they call “the wall” at the event, a 146″ modular TV featuring self-emitting MicroLED technology promise lower power consumption, and longer life time.

Samsung IoT Security News – ARTIK Secure IoT Modules, SmartThings Cloud, and Secure Element

October 19th, 2017 No comments

Samsung has made several announcements with IoT, especially IoT security. First, Samsung ARTIK 053, ARTIK 530 and ARTIK 710 modules are getting an “s” version, which stands for “robust security”, as well as a new ARTIK 055s module, and all ARTIK modules can now work with SmartThings Cloud uniting the company’s existing services – ARTIK Cloud and Samsung Connect Cloud – into a single IoT platform.

Separately, the company announced their Secure Element solution which combines eFlash memory and new security software.

Samsung ARTIK “s” modules & ARTIK 055s

The company explains in their blog that ARTIK 053s, 530s, 710s, and the all new 055s will feature “advanced protection, integrated cloud services, and hosted security services with “enhanced ARTIK end-to-end security by providing greater protection for IoT data as well as prevention against hacking”.

The press release is a little more specific:

ARTIK secure IoT modules provide a strong root of trust from device-to-cloud with a factory-injected unique ID and keys stored in tamper-resistant hardware. Samsung’s public key infrastructure (PKI) enables mutual authentication to the cloud to identify each device on the network and support whitelisting. Customers can use the new Secure Boot feature and code signing portal to validate software authenticity on start-up. In addition, the secure IoT modules provide a hardware-protected Trusted Execution Environment (TEE) with a secure operating system and security library to process, store, and manage sensitive resources, including keys and tokens on devices. Information is protected using FIPS 140-2 data encryption and secure data storage.

The product briefs somewhat help us better understand what has changed with the “s” version.

So it appears the modules were previously secured with a “Secure Element”, and now the company has added KMS and secure boot support to the “s” version, as well as TEE to the more powerful ARTIK 530s and 710s modules. The company claims there will no increase in price for the (more) secure modules.

Samsung ARTIK 055s Smart IoT module (pictured above) is similar to ARTIK 053(s), but is quite smaller, and works at 3.3VDC, instead of the 5-12VDC. ARTIK 055s specifications with highlights in bold showing differences with ARTIK 053:

  • MCU – 32-bit ARM Cortex R4 @ 320MHz with 1280 KB RAM for general use, 128 KB RAM for global IPC data
  • Storage – 8 MB flash
  • Connectivity – 802.11 b/g/n WiFi @ 2.4 GHz
  • Expansion – 29 dedicated GPIO ports, 2x SPI, 4x UART (2-pin), 4x ADC, 1x JTAG, 2x I2C
  • Security – AES/DES/TDES, SHA-1/SHA-2, PKA (Public Key Accelerator), PRNG/DTRNG (Random Number Generators), Secure key storage, Physical Unclonable Function (PUF)
  • Power Supply – 3.3 VDC input voltage
  • Dimensions – 26 x 15 x 3 mm
  • Temperature Range – -20 to 85°C
  • Certifications – FCC (U.S), IC (Canada), CE (EU), KC (Korea), SRRC (China)

The documentation does not list any hardware differences with regards to security, but Tizen RT OS adds secure firmware and JTAG protection for 055s and 053s.

In other news, Samsung ARTIK 530(s), ARTIK 710(s), and future Linux based ARTIK modules will now default to Ubuntu 16.04, instead of Fedora used so far.

Samsung Secure Element

We’ve just seen older ARTIK modules included a “Secure Element”, but Samsung has just added to confusion by introducing an “integrated Secure Element (SE) solution for Internet of Things (IoT) applications that offers a turn-key service for both hardware and software needs”.

The SE includes an embedded flash (eFlash) and will stop and reset itself whenever it detects abnormal activity. The solution also comes with security software that supports personal verification, security key storage, encoding and decoding, and secure data transfer between devices servers and clouds.

The SE and developer board are showcased at the Samsung Developer Conference, but that’s all the information I have so far, as I could not find any info about Secure Element or W1650 chip on Samsung website.

Linux on Galaxy to Bring Linux Desktop to Samsung Note8, Galaxy S8 and S8+ with DeX Station

October 19th, 2017 13 comments

Earlier this year, Linux desktop mobile convergence took a serious hit when Canoncial decided to drop support for Unity and Mobile Convergence in their Ubuntu distributions, focusing instead on the enterprise and IoT market, and replacing Unity by GNOME starting with the just released Ubuntu 17.10.

Things started to look better with Purism Librem 5 Linux smartphone, which has now raised $1.8 million dollars, and partnered with well-known members of the Linux ecosystems like KDE, GNOME, and NextCloud. However, the phone will be based on a rather low end NXP i.MX 8M quad Cortex A53 SoC, is scheduled for January 2019 only, and being a crowdfunding campaign, failure is always a possibility.

But today, the outlook for Linux phones brightened even more, as Samsung unveiled plans for “Linux on Galaxy” at the Samsung Developer Conference 2017.

Samsung Dex with Android

The solution will leverage the company’s DeX (Desktop Experience) that relies on DeX Station – a dock for Samsung Galaxy S8, S8+, and Note8 smartphone – that connected to a big display, as well as a special Android desktop mode that supports multi-window, comes with a start menu, etc…

Linux on Galaxy app will enable developers and users to leverage Samsung DeX hardware (station + smartphone) to run their preferred Linux desktop distribution(s) using the same kernel that powers Android OS. For example, developers will be able to code using their mobile on-the-go, and with Samsung DeX, continue their work on a larger display.

Samsung Linux on Galaxy is still a work in progress, and the project is still private. But if you are interested, you can register your interest in order to get notified when it goes public.

UFS 3.0 Embedded Flash to Support Full-Duplex 2.4GB/s Transfer Speeds

September 10th, 2017 3 comments

All my devices still rely on eMMC flash for storage, but premium smartphones, for example, make use of UFS 2.0/UFS 2.1 flash storage with performance similar to SSD, with Samsung UFS 2.0 storage achieving up to 850MB/s read speed, 260 MB/s write speed, and 50K/30K R/W IOPS. UFS 3.0 promises to roughly double the performance of UFS 2.0/2.1 with transfer rates of up to 2.4 GB/s, and separately, the UFS Card v2.0 standard should deliver UFS 2.1 performance on removable storage.

Several Chinese and Taiwanese websites, including CTimes and Benchlife, have reported that companies have started getting UFS 3.0 & UFS Card v2.0 licenses from JEDEC, and Phison is working on a controller to support both new standards, and scheduled to launch in 2018.

Premium smartphone SoC are only expect to support UFS 3.0 in 2019 and beyond, and hopefully by that time eMMC will have been replaced by UFS 2.0/2.1 in entry level and mid range devices. The outlook for UFS cards is less clear, as I’ve yet to see a product equipped with a UFS slot.

Based on a recent presentation at the Flash Memory Summit, (typical) embedded storage capacity will also increase to 32GB for IoT / multimedia applications, 256GB for smart home products and drones, 512GB for mobile devices, and over 1TB for automotive applications.
