Samsung & Amazon Introduce HDR10+ Standard with Dynamic Metadata & Tone Mapping

Most recent 4K Ultra HD televisions support high dynamic range (HDR) through standards such as HDR10, Dolby Vision, or Hybrid Log-Gamma (HLG). Samsung and Amazon have jointly introduced an update to HDR10 with HDR10+ that adds dynamic tone mapping & metadata. The companies describe the issues for HDR10′ static metadata as follows: The current HDR10 standard utilizes static metadata that does not change during playback despite scene specific brightness levels. As a result, image quality may not be optimal in some scenes. For example, when a movie’s overall color scheme is very bright but has a few scenes filmed in relatively dim lighting, those scenes will appear significantly darker than what was originally envisioned by the director. HDR10+ will be able to adjust metadata for each scene, and even for each frame, hence solving the issue of darker scenes. If you already own a Samsung TV with HDR10, it’s not […]

Secure IoT Connectivity with NodeMCU ESP8266 Board, ATECC508A Crypto Chip, Mongoose OS, and AWS IoT

There are many examples of Internet of Things projects, but more often than not the implementation is not secure, either because the device is exposed to the Internet with minimum or no security (worst case), or a gateway (hopefully) provides secure connection to the Internet, but the communication between sensor nodes and the gateway in the local network is not secure, due to memory limitation of the nodes, for example it might be challenging to implement security on ESP8266. Mongoose OS is an open source operating system for the Internet of Things developed by Cesanta working on ESP32, ESP8266, STM32, and TI CC3200, and the developers have demonstrated a secure solution with Mongoose OS running on ESP8266 connecting over a TLS connection to AWS IoT (Amazon Web Service IoT) and using TLS credentials stored in Microchip ATECC508A CryptoAuthentication Device. The addition of ATECC508 chip either using “XplainedPro extension board for […]

Netgem SoundBox is a Speaker with Built-in Set-Top Box Features

Netgem, a company specializing in Connected TV & Home, has sent a press release about profit growth, and two new “innovations int its smart home roadmap” with voice control with Amazon, and SoundBox, a connected speaker which embeds set-top box technology. Netgem does not sell directly to consumers, but instead sell its products and solutions to service providers, and they have not provided a great deal of technical details. But we still know the company has improved Netgem Home Platform, a cloud service allowing the deployment and management of multi-screen features, content discoverability, with support for multi-room, multi-source music service through technology from Voxtok. SoundBox will then offer both video and audio service, and be controlled by voice using Amazon Alexa. The SoundBox will be customized for each Telco to adapt to the needs of local markets. A few more details may eventually surfaced on Netgem’s SoundBox product’s page. They’ll […]

Seagate Duet Portable Hard Drive Automatically Syncs with Amazon Cloud Drive

Seagate has announced the launch of Seagate Duet 1TB portable hard drive with auto-sync to Amazon Cloud Drive, so that your data is always backed in the cloud. If you use the drive to backup data, that means you’ll have a extra backup copy in the cloud, which could be useful if the drive fails just when you want to back it up (it happened to me), or somehow your house burns down… Another advantage is that if you forget to take your drive with you, the data will be accessible from anywhere with an Internet connection from Amazon Cloud service. It connects through your Mac or PC’s USB 3.0 port, and sync files to the cloud after an initial setup with your Amazon account. Once the setup is done, you can use the drive as you’d normally do, and files will automatically be backed up in the cloud. The […]

Marvell EZ-Connect MW302 IoT Starter Kit Supports AWS IoT Cloud Services

Amazon has just launched AWS (Amazon Web Services) IoT (Beta), a cloud platform that lets connected devices securely interact with cloud applications and other IoT devices. As pasrt of the announcement, they also released AWS IoT SDK that comes in three flavors: Embedded C SDK for C-based platforms such as Linux, RTOS, with variants for OpenSSL and mbed TLS. JavaScript SDK in Node.js Arduino Yún SDK. Ten started kits are currently officially supported by AWT IoT, many of them being existing platforms such as LinkIt One, BeagleBone Green, Intel Edison, or TI LaunchPad CC3200, with several of these kits including SeeedStudio’s Grove modules. One of the kits that’s completely new, at least to me, is Marvell EZ-Connect MW302 IoT Starter Kit which include a mini USB to USB cable, and Marvell 88MW302 development board with the following (preliminary) specifications: SoC – Marvell EZ-Connect MW302 ARM Cortex-M4 WiSoC with 512KB SRAM […]

Nvidia Shield Android TV vs Apple TV vs Roku 3 vs Fire TV vs Nexus Player – Video Capabilities and Features Comparison

Since Nvidia released the Shield Android TV box, I’ve heard several people saying Nvidia raised the bar and even disrupted the TV box market by bringing a powerful HTPC and gaming console to the market for just $199. The company has now released OTA 2.0 firmware that improves HTPC capabilities, including under Kodi and Plex, and the box supports for 10-bit HEVC, H.264, and VP9 @ 4K, and audio pass-through for HD audio codecs such as Dolby TrueHD and DTS-HD Master. As part of the release announcement, Nvidia also compared the Shield TV media capabilities to the ones of other US centric media players, namely Apple TV (2015), Roku 3, Amazon Fire TV (2015), and Nexus Player. Since it comes from Nvidia, it was also going to show the Shield TV in a good light, but I’m very surprised to see that Apple, Amazon, Google, and Roku would ship a […]
