In addition to Samsung, Comcast is “working with several others” on apps that will allow the MSO to deliver 4K video on-demand directly to the TV over broadband, MSO executive vice president and chief technology officer Tony Werner said here on a 4K panel.
“We are keen on 4K,” he said.
Although Comcast’s initial foray into 4K will rely on public Internet connections, Werner is not overly concerned about the amount of bandwidth it will require to deliver. “We like bandwidth-intensive applications,” he said. “Bandwidth is our friend, and it’s the business that we’re in.”
Out on the show floor, Comcast and DirecTV are both demonstrating 4K delivery to Samsung’s new-generation 4K TVs, which use HEVC encoding and contain the technical innards to decode Ultra HD video. Mark Francisco, fellow of premises technologies for Comcast Cable, who was here running the demo (see image above), said he expects that Comcast’s VOD 4K streams will require speeds of 15 Mbps to 20 Mbps.
“We’re still dialing that in. The last thing I want to do is be stingy on the bits,” Francisco said.
Although Comcast will start to offer native 4K directly to Samsung smart TVs, Werner said the MSO is working on a next-generation of boxes for its X1 platform that use HEVC and can decode native 4K signals. He said those boxes should be available sometime later this year. Comcast’s current-generation boxes for X1 will be capable of delivering 1080p HD that can be upcoverted by Ultra HD sets.
Werner said Comcast has conducted tests showing that upconverted 1080p video on 4K TVs look “far superior” compared to how it looks on standard HD sets.
“Upconverted content absolutely looks better,” agreed Tom Cosgrove, president and CEO of 3net, which expects to produce up to 80 hours of Ultra HD content this year.
While that’s a positive that could nudge consumers to buy 4K sets before much native 4K content is available, panelists warned that the visual benefits of upconverted HD could represent a double-edged sword.
The concern is that those improvements could give programmers and studios “reason to rest on their laurels” and perhaps slow down the production of native 4K movies and TV shows, Werner said.
“The real killer selling point for 4K is seeing native 4K,” Cosgrove added.
For that reason, it’s important for programmers to produce shows and movies in 4K so those titles can be delivered in that format down the road, said Chris Cookson, president of Sony Pictures Technologies.
As a point of emphasis, he said Sony Pictures shot AMC hit series Breaking Bad on 35 millimeter film and originally scanned it for standard HD. It has since been rescanned and post-produced in 4K. Netflix announced here this week that it will be offering Breaking Bad in 4K sometime later this year.
“The difference between HD and the 4K version was substantial,” Cookson said, adding later that “future-proofing” content for later distribution in windows such as syndication offers studios a strong incentive to produce most of their content in 4K today.
Despite some concerns, Werner believes upconverted HD on 4K will provide a “more seamless migration” than what was witnessed during the move to standard-def to HD. SD video on HD sets looks horrible, he said.
Werner said the ingredients for 4K to take off are coming together. Comcast, he said, has the distribution network to deliver 4K and will soon have access to more end-points that can decode 4K. What’s still lacking is lots of 4K content.
Comcast, he said, has some 4K plans in store for NBCUniversal’s coverage of the Sochi 2014 Winter Olympics. He didn’t say exactly what the operator will offer, but noted that the effort will attempt to “stimulate the imagination” around the delivery of sporting events in 4K at high frame rates.
