By "copper," he means voice grade twisted pair.
Also, you can now buy 4K sets, with relatively small screens, for truly
affordable prices. Already under $1000, for 40" sets, and $1300 for 49" sets.
At Best Buy. (I paid $1200 for a 26" LED HDTV set, less than 10 years ago!)

CES 2015: Ultra-High-Definition 4K TV over Copper
Sckipio G.fast enables telco delivery of 4K TV

ORLANDO, Fla. - Want to watch UHDTV? Try your telco's copper. The first
ultra-high-definition (UHD) content delivered to a 4K TV over existing
twisted-pair copper infrastructure of telecommunication companies (telcos) was
demonstrated at the International Consumer Electronics Show (CES 2015, Jan.
6-9, Las Vegas). Sckipio Technologies' (Ramat Gan, Israel), which makes G.fast
(pronounced gee dot fast) chipsets, claims DSL cannot deliver UHD 4K TV, but
its G.fast ultra-broadband networks can over standard telco twisted-pair copper
lines.
Demonstrated for the first time at CES, 4K TV can now be delivered from Netflix
and other providers by simply swapping out consumers current equipment for a
G.fast model, according to David Baum, CEO of Sckipio Technologies, in a press
statement. Baum claims that up to 16 concurrent subscribers can be supported
with 4K TV per telco distribution point.
G.fast for UHD 4K TV was just approved by the International Telecommunication
Union (ITU) last month and delivers up to 1 Gbit per second (Gbps) over
standard copper telephone lines. The typical infrastructure uses fiber lines to
deliver high-definition signals -- 200Mbps per four subscribers -- to a
distribution point close to 16 subscriber homes. From there G.fast delivers the
UHD 4K TV signal over standard copper lines for the last 400 meters (1,312
feet).
So far, Sckipio only has a reference designs for a 16-port distribution point
unit (DPU) feeding 16 Sckipio CP-1000-EVM over 50 meters (164 feet) to consumer
premises equipment (CPE) connected to a set-top box or in some cases directly
to the 4K TV. On this set up, each G.fast 4K video stream delivered about
65Mbps.
The set-up also included the first OpenFlow demonstration over a commercial
G.fast distribution point unit. The open framework should speed telco adoption
over proprietary alternatives, according to Baum, who noted that OpenFlow is a
more modern way to control data flow by serving as the enabling component in a
software defined network. SDNs allow quick configuration by telcos for
independent point-to-point connections.
Baum promised that its demonstrated reference design will be available in
commercial units by the end of 2015.
