Dolby Digital (AC3) US Patent Has Expired on February 1, 2017

Many TV boxes cannot play videos with Dolby Digital (AC3 ) audio because they lack the license, except if you use software like Kodi that downmixes the audio, but most apps won’t, and MX Player developers had to remove AC3 support from the Android app previously. But based on a forum post by Popcorn Hour, Dolby Digital AC3 US patent (that one?) has expired at the beginning of this month, so they can legally enable AC3 downmixing in their TV box that previously lacked the license including Popcorn Hour A410U/VTEN-U/A-500U/A-500 PRO-U. That’s probably good news for other TV boxes too, as going forward, there’s no need to have Dolby Digital license to play AC3 content. Hopefully, apps and firmware images will be updated to reflect this change. You’ll still need a license for newer formats like Dolby True HD and Dolby Atmos however.

HDMI 2.1 Specification to Add Support for 4K @ 120 Hz, 8K and 10K Resolutions. New 48G Cable Required.

The HDMI Forum has just announced they’ve been working on HDMI specification Version 2.1 adding new video resolutions and refresh rates including 8K60 and 4K120, as well as dynamic HDR, and increased bandwidth up to 48 Gbps for uncompressed 8K videos with HDR. The new specification also includes support for eARC (enhanced audio return channel) with support for advanced audio formats such as object-based audio, and advanced audio signal control capabilities including device auto-detect. Game Mode VRR is another new feature from HDMI 2.1 with variable refresh rate to enable a 3D GPU to display the image at the moment it is rendered in order to reduce lag and frame tearing. Beside 4K120 and 8K60, the new specification also handles 4K, 5K, 8K, and even 10K resolutions at various frame rates between 50Hz to 120 Hz, up to 10K @ 120 Hz. Higher resolutions and frame rates (>=4K @ 120Hz; […]

LG TONE Wireless Bluetooth Speakers & Earbuds Get Charged with a Neckband

Battery powered Bluetooth speakers are very common, and Bluetooth earbuds even more, but both are normally designed for different use cases. Last year ZAGG decided to bring both into a single product that you wear around your neck: Flex Arc Wireless Bluetooth earbuds + speakers now selling for about $56. The obvious advantage is that it includes larger battery than you can fit in earbuds and most Bluetooth headsets. ZAGG will soon be getting some competition as LG has designed two Bluetooth audio products leveraging your neck with LG TONE Studio (HBS-W120) equipped with a Hi-Fi DAC, 4 speakers, and two earbuds, and LG TONE Free (HBS-F110) with 2 “true wireless” earbuds that can be storage and charged in their neckband. The latter can also vibrate for incoming calls and text messages. An extra charging cradle is also provided for use cases when the neckband might not be convenient. LG […]

You Can Buy AirPods-like Wireless Bluetooth Stereo Earbuds for $16 and Up

Most Bluetooth headsets on the market actually come with some sort of wire or holding mechanism, which may not always be convenient, for example I can’t use mine comfortably while lying down on the bed. But that to electronics miniaturization, companies have recently started to offer truly wireless Bluetooth earbuds, including Apple’s yet-to-be available $159 Airpods. This morning I noticed two similar products in new arrivals list, first with $59.99 QCY Q29 mini Earburds on GeekBuying, and then even cheaper, but not quite as good looking (and likely not so good sounding), “FreeStereo Twins Wireless Bluetooth v4.1 In-Ear Headset w/ Mic” on DealExtreme going for just $22.25 including shipping. Let’s start with QCY Q29 earbuds specifications: Connectivity – Bluetooth 4.1 with HFP, HSP, A2DP, AVRC protocols support; up to 5-10 meter range Built-in Microphone Charging port – pogo on earbuds, micro USB to storage/charging box Battery – 45mAh for up […]

$49 Dashbot Car Dashboard Assistant is Powered by C.H.I.P Pro Allwinner GR8 Module (Crowdfunding)

Most companies specializing in development boards may sell a few accessories for their boards, but usually leave product design to their customers.

Dashbot hardware specifications: CPU Module – CHIP Pro with Allwinner GR8 ARM Cortex A8 processor @ 1.0 GHz, 512MB NAND flash, 256 DDR3 RAM, 802.11 b/g/n WiFi, Bluetooth 4.2 External Storage – micro SD slot Display – Red LED display Audio – 32-bit audio DSP for beamforming & noise suppression; fairfield audio pre-processor with 24-bit ADC; high fidelity MEMS microphone array (106 dB dynamic range) USB – 1x USB host port Power Supply – 5V via USB port or 12V via power port (aka cigarette lighter) + backup LiFePo4 […]

Giveaway Week – Vana Player Linux Based HiFi Audio Player

After giving away a virtual reality headset on Monday, and a TV box on Tuesday, I’ll offer a very unique device for the third day of this giveawat week with Vana Player, an HiFi audio player based on Allo Sparky ARM Linux development board. Beside the development board the kit includes two audio DAC boards, a 30W amplifier, a reclocker board, a capacitance multiplier board, and accessories like an acrylic “case” and a power supply. The system is running Ubuntu 12.04 with Max2Play web interface to configure the system running a SqueezeBox server, Kodi and more. I found a few bugs during my review, but the company has now released a new firmware update that should fix many of the issues I encountered. All items shown above will be included in the package. Note that you’ll also need a 19.5V power supply, for example from an old laptop to power […]
