Qualcomm Showcases 4K LTE HDMI TV Streaming Dongle

There are now many wireless display adapters supporting Miracast, EZCast, DLNA, Airplay…, and streaming videos from your smartphone to the TV over Wi-Fi in 720p or 1080p resolution. Qualcomm recently unveiled a prototype called “4K Stream Adapter (4SA)” that does about the same but instead support 4K UHD resolution, and allegedly supports LTE thanks to its Qualcomm Snapdragon 800+ processor. According to a PCWorld report, Qualcomm mainly expects the device to be used to stream 4K video captured with a phone to a 4k UHD television, but it might also ending up supporting online video services such as Netflix, and mirroring your mobile device’s display onto the big screen. It’s also said to use a “basic Universal Plug and Play protocol” to connect with other devices, and the company is working to support communication with media apps such as BubbleUPnP, VLC and MXPlayer. Currently 4SA is only a prototype to […]

Mini PC Polls: Networking Connectivity, Video and Audio Outputs

It’s always interesting to find out how people use their devices, and I recently discovered Google+ support Polls as Droidmote posted a poll to find out whether people used Wi-Fi or Ethernet with their mini PCs, and I followed up with polls about video and audio outputs. Around 50 people have answered to each poll up to now, so even if it may not representative, let’s have a look at the results so far. About half of the people are connected via Ethernet, and the other half are using Wi-Fi after 43 votes. Wi-Fi is normally more convenient, but may not be as reliable, and for users playing high bitrate videos Ethernet is a must, unless you find buffering enjoyable…. After 58 votes, most people still connect their mini PC to a Full HD television via HDMI, with a few connecting it to a 4K UHD TV, and nobody using […]

Can Rockchip RK3288 Android TV Boxes Play Videos at True 4K UHD / 2160p Resolution?

[Update 2: Now that I have a 4K TV, I’ve redone the test myself, and Rockchip RK3288 can play 4K videos properly. The mistake was to use Software decode in MX Player which renders to the framebuffer instead of the video buffer. Visit the post entitled 4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards for details.] [Update 1: The post has now been updated, after it was clear one of MX Player options was misunderstood. The conclusion remains the same] Over the last few years there have been complains about Android TV boxes decoding 1080p video, rendering them to a 720p frame buffer, and upscaling them back to 1080p resolution for video output, so you ended up playing 1080p videos at a real 720p resolution. I never investigated the issue in details, and thanks to new media players now coming with a 1080p […]

Test Your 4K Device True Resolution With a 4K UHD / 2160p Video Test Pattern

Now many products are sold on the market advertising 4K video output, but how to test and check if it just a lie with only part of the system support 4K (e.g. physical video output), but the rest of the system makes you lose quality? When I worked on DVD players, we had some special DVDs with video pattern allowing us to test different video quality. You can read about different video test patterns in “AVSHD 709 DVD document“. There are also some expensive equipments such as DVDO AVLab TPG – 4K Test Pattern Generator that generate test patterns to calibrate video equipments, but if all we want to do is to check the resolution has not been tempered with there must be a cheaper and easier way. After having a discussion about this issue on Google+, Dan Car decided to create a 2160p (3840×2160) test pattern image with some […]

Review of Kingnovel K-R68 (R6) Android Mini PC

I’ve already listed specs, and shown a few pictures of Kingnovel K-R68 (R6) Android media player based on the latest Rockchip RK3288 quad core processor. I’ve now gone through all my usual tests, so today, I’ll write the review, going through the user interface, testing video playback, reporting one various performance benchmarks including network and storage performance, tested most hardware features, and played a few games. First Boot, Settings and First Impressions Albeit there’s an infrared remote control with the device. I’ve not used it all, especially, as we’ll see below the default user interface is the stock Android home screen. As usual, I’ve connected an RF dongle to use Mele F10 Deluxe air mouse. Before powering up the device, I’ve also connected an HDMI cable, a USB hard drive, and an Ethernet cable. Albeit there’s a power button, the device will boot automatically as you connect the power adapter, […]

Review of UyeSee G1H Rockchip RK3288 Android TV Box

UyeSee G1H is one of the first Android TV boxes powered by Rockchip RK3288 quad core Cortex A17 SoC. I’ve already listed specs, and shown a few pictures of the device and the board in my “UyeSee G1H Unboxing” post, so today I’ll write a full review, checking out the user interface, testing video playback capabilities, network and storage performance, play a few games, check hardware features are working as expected, and runs some benchmarks on the platform. First Boot, Settings and First Impressions There’s an infrared remote control with the device. I’ve inserted a CR2032 battery, and although it works great in the user interface, it becomes useless with Android apps, so instead I’ve opted to use Mele F10 Deluxe air mouse which brings mouse and keyboard support. Before powering up the device, I’ve connected an HDMI cable, the RF dongle for Mele F10 Deluxe, a USB hard drive, […]
