Not soon. I have heard of no programmers that plan 4K. Plus, are any of Cox's STBs 4K? [no]Hello does anyone know when Cox Cable will have 4K programming ??
Direct Tv has 4k programming for 2015 so I guess I will switch to Direct Tv ....they also have NFL sunday Ticket ...thats a big PLUS for me !!Not soon. I have heard of no programmers that plan 4K. Plus, are any of Cox's STBs 4K? [no]

Here's a publication specializing in UHDTV production/potential broadcasting. -- John
All of DirecTV's OnDemand stuff (not their scheduled PPV movies and events) is delivered via the internet, not through their satellite signals.
That's a very odd rumour. I'm happily tuning a DVB-S2 HEVC 4K test broadcast from Astra at 28.2E in the UK with TBS PCI-E and Technisat USB DVB-S2 transponders. Similarly my Sony UHD TV set, which has integrated DVB-S2 tuners, is also tuning the Astra UHD tests with no problems. That's live-to-air UHD (aka 4K) in HEVC.The directv Genie DVR has 5 independent tuners, rumor has it it will need 2 tuners simultaneously to watch live 4k once available due to its massive bandwidth.
I honestly don't know where that rumor started, or if it is true. It possibly could be a limitation of directv's SWM(single wire multiswitch) system which allows up to 13 tuners on a single cable.That's a very odd rumour.

Unless DirecTV are going to be using a new version of DVB-S2 like S2X then the bandwidth of the transponder is unlikely to change. The video data rate may well be higher than before but nothing mad that a current S2 demod and demux can't handle - unless the DirecTV stuff is very shonky.
I guess you could be in a situation where the Genie can't use all 5 tuners simultaneously to record because the disk bandwidth would be too high to record 5 x UHD streams rather than 5 x HD streams - so rather than it needing 2 tuners, it just stops one being used when another is tuning 4K to limit disk bandwidth?
For info - the BBC UHD tests (which were OTA using DVB-T2 rather than DVB-S2 over satellite) over the summer last year for the World Cup and Commonwealth Games used HEVC at 2160/59.94p and 2160/50p at around 38Mbs. The Astra test broadcasts are at around 20Mbs. I expect a formal service will be somewhere in between?
When H264 1080/50i broadcasts started in Europe around 2006, it wasn't uncommon for them to use 16-18Mbs for an HD signal - so the bandwidth used for UHD HEVC isn't that massive...
When did the Genie launch? It must have been recently if it included HEVC / H265 hardware decoding for 4K reception.
Odd - AIUI SWM is similar to the European SCR system, which just transposes a specific transponder to a specific IF slot (one IF slot dedicated to each tuner - to avoid the issues with polarisation and band clash that would otherwise be the case with a conventional LNB) so shouldn't offer a bandwith limitation. The RF transponder config for UHD vs HD is the same - it demodulates to a transport stream in the same way. The difference is once the demodulated transport stream is processed - as it contains a UHD rather than HD or SD video stream, and is usually in HEVC/H265 rather than AVC/H264 or MPEG2/H262 format. The RF sent down the cable to the tuner is essentially the same - it's a transponder's worth of RF.I honestly don't know where that rumor started, or if it is true. It possibly could be a limitation of directv's SWM(single wire multiswitch) system which allows up to 13 tuners on a single cable.
Nobody in their right mind would be doing UHD using H264 - and if the decoders weren't 4K compatible you'd be stuck with 1080i or 1080p (depending on H264 supported level). I very much doubt the HR44 would have the capability to stitch 4 x 1920x1080/60p H264 streams together, which is the other way UHD has been distributed via satellite (either for contribution or because there weren't suitable 2160p encoders available - which there now are)The most current HR44 genie does not decoded H265, only H264
LOL! well directv is going to try apparently.Odd - AIUI SWM is similar to the European SCR system, which just transposes a specific transponder to a specific IF slot (one IF slot dedicated to each tuner - to avoid the issues with polarisation and band clash that would otherwise be the case with a conventional LNB) so shouldn't offer a bandwith limitation.

Interesting. 3840x2160 @ 60p is H264 Level 5.2 and requires HDMI 2.0 for 2160/60p output (can be implemented within HDMI 1.4 bandwith but to do so requires 4:2:0 over HDMI which was added as part of the HDMI 2.0 spec. Some HDMI 1.4 hardware may be driver upgradeable - nVidia video cards are)LOL! well directv is going to try apparently.
