Comment Re:The US can only do this by Phasing out CDMA. (Score 2) 47

Qualcomm holds patents in all kinds of things. In 5G, it holds Standards Essential Patents in the Radio Access Network (RAN), modulation & waveforms, and core networking.

In RAN, centimetre wave (10GHz-30GHz) and millimetre wave (30GHz-300GHz) radio, beam steering or beamforming techniques, and massive MIMO IP are held by Nokia, Ericsson and Qualcomm.

In modulation, 5G requires non-orthogonal transmission schemes, rather than the OFDM of LTE-Advanced. Some schemes under consideration include Filter-Bank Multi-Carrier (FBMC) transmission, Universal Filtered Multi-Carrier (UFMC) transmission and Generalised Frequency-Division Multiplexing (GFDM).

In networking technologies, Network function virtualisation (NFV) and software defined networks (SDN), Inter-Node Coordination and backhaul, Access Link Integration, Self Organising Network (SON) technology, Context Aware Networking, Information Centric Networking, not to mention good old WiFi. Nokia, Qualcomm, Cisco, Intel and Ericsson are the top IP holders.

That leaves Apple as the holdout supporting only codecs that require payment of a royalty to a patent pool.

Alternative, that leaves Apple as the holdout of supporting a codec whose intellectual property is not well understood, and might infringe on some submarine patents waiting to surface...

A car costs $300-$400 per month until you pay it off (especially if you include maintenance), that tends to be more than my typical business travel car rental.

My household has a single (gasoline) vehicle, the few times we really need a second car for around the town we use Uber, still cheaper than owning a second car.

Comment Colors (Score 3, Informative) 190

The claim is "they can express all colors at any level of brightness".

Currently every shipping consumer television (inorganic LED or OLED) can only display the DCI-P3 color primaries, making the entire color gamut a triangle substantially smaller than "all colors".

Newer sets are able to receive color information in a container based on ITU-R Rec. 2020 color primaries, however no sets can actually display the colors outside of DCI-P3 but inside ITU-R Rec. 2020. Moreover, even the gamut of Rec. 2020 is not "all colors."

To have a container for all colors with three primaries, you have to have color primaries that are not realizable, such as the CIE 1931 XYZ space or the ACES color space.

However no one has yet invented a display system that can display colors that are not realizable, because they are not realizable.

No system can display "all colors" additively, unless you use a system with color primaries based on all of the monochromatic colors (i.e. much more than three primaries - thousands). Four or five color primaries added together can get close. Allowing subtraction as well as addition of color primaries can help, but that is difficult to realize.

Comment Re: No bandwidth legally available. (Score 1) 22

ATSC A/53 was adopted by the FCC as the US digital TV broadcasting system in 1996.

At the time, there was no standard method to carry 1080p60 10-bit production video. HD Serial Digital Interface (HD-SDI) topped out at 1.5 Gbps.

It wasn't until 1998 that SMPTE standardized 372M Dual link HD-SDI that could have even carried 1080p60. SMPTE 424M that could carry 1080p60 uncompressed in a single 3 Gbps SDI link did not show up until 2005.

If you are an American living and working legally in France for five years, or you are married to or were born to a French citizen, you may apply for French citizenship.

If youâ(TM)ve successfully completed two years of higher education in France, the five-year residency period can be reduced to two years.
