I HAVE NO PROOF? or you don't? I do! I have
video clips of setting/streaming data posted
immediately prior to streaming; I have seen
information made available to shareholders
since I have been following NTEK for OVER
A YEAR!! big smile

Publicly available information the company has
provided its' shareholders. Sorry but once again:

GET THE FACTS!!!



Here is a list of devices that are capable of streaming 4k.

Laptop/Desktop:
You can stream 4k videos on your laptop or desktop. Currently there isn’t too much content, but it is out there. Free videos can be found on Youtube. M-GO, Vimeo and NanoFlix have 4k streaming services. Amazon and Netflix are said to start adding 4k content very soon. To turn your computer into a 4k streaming device, you will need these minimum system requirements.

Streaming 4K H.264

CPU: Quadcore 1.5+ Ghz
GPU: HD Graphic Card/Chip with 50-100+ Gflops
Memory: 2GB Dual Channel
Bandwidth: 20-25 Mbps
HDMI Output: 1.4, 2.0

Stream 4K H.265

CPU: Quadcore 2.0+ Ghz
GPU: HD Graphics Card/Chip with 200+ Gflops
Memory: 4GB Dual Channel
Bandwidth: 12-15 Mbps
HDMI Output: 1.4, 2.0

Gaming consoles:
Although the PS4, and Xbox1 currently cannot stream 4k, both companies state they will be able to once they update their firmware.

Smart TVs:
All smart televisions are capable of streaming 4k H.264. HEVC 4k TVs are coming out soon, including LG’s webOS and Roku TV.

4k Top Set Boxes:
January 2014: Nanotech's NP-1 and NP-H1 using H.264/V9 (I do not believe H.265 upgradable)
Q1-Q2 2014: Technicolor and Humax are said to be using chipsets that support 4k HEVC streaming.

Here is an article worth reading about all of the 4k devices I listed + some others.

Snapdragon 800 vs Tegra 4 CPU


Qualcomm’s Krait 400 does 3.5 DMIPS/MHz per core.

Nvidia’s Cortex A15 does 4.01 DMIPS/MHz per core.

Qualcomm 800 CPU performance is = 3.5 DMIPS/MHz per core * 4 Cores * 2.3 GHz = 32,200 DMIPS.

Tegra 4 CPU performance is = 4.01 DMIPS/MHz per core * 4 Cores * 1.9 GHz = 30,476 DMIPS.

This goes to show you why I still do not believe that the NP-1’s hardware is capable of streaming 4k using the H.265 HEVC codec. The Qualcomm 800 has a slightly faster CPU and a way more powerful GPU than Nvidia's Tegra 4. And even Qualcomm has stated that their Snapdragon 805 is their first 4k HEVC capable mobile chipset. Their older chipset, the Snapdragon 800 can stream 4k, but only using the old H.264 MPEG-AVC codec. The Snapdragon 800 is only capable of streaming 1080P with the H.265 HEVC codec. The NP-1 can only stream 1080P HEVC, or 4K H.264. NOT 4k HEVC!

Snapdragon 805....

"Featuring the new Adreno 420 GPU, with up to 40 percent more graphics processing power than its predecessor, the Snapdragon 805 processor is the first mobile processor to offer system-level Ultra HD support"

"Ability to stream more video content at higher quality using less power: Support for Hollywood Quality Video (HQV) for video post processing, first to introduce hardware 4K HEVC (H.265) decode for mobile for extremely low-power HD video playback."

Here is my 4k Bandwidth test and results!

Youtube and the NP-1 use the same H.264 MPEG-4 AVC codec for streaming. If the NP-1 is running V9 now, it should require slightly less Mbps than H.264, but still more than H.265.

Click on the video link below and change the settings quality to 2160P (4k). If your video buffers then you need to upgrade your internet connection to stream 4k using the NP-1...

Make sure your browser has H.264 support here

I have Comcast 50Mbps and I didn’t have to buffer. My internet is being broadcast through a wireless router and I lose some Mbps. Speedtest.net is currently showing my Mbps at 25Mbps. If my Mbps drops under 20, the streams begin to buffer.

If my laptop was running 4k Netflix with HEVC H.265, my bandwidth would only have to be 12-15 Mbps. This is why the H.265 HEVC codec is very important. Even Netflix says you need 15 Mbps to stream 4k through HEVC. This is why I am confused when Foley states the NP-1 can stream 4k 6-10Mbps. If this is true, they must be sacrificing image quality. Not only does H.265 require less bandwidth than V9 and H.264, it also has a higher quality image!
