There are no problems with transmitting 4K over terrestrial or satellite systems today.
The only part that is lacking is commercial receivers.
This year Broadcom (among others) will distribute HEVC processor chips (SoC) in 2013 for companies to design commercial equipment and start mass-production of this in 2014.
From then on both UHD TVs and Satellite receivers can receive UHD signals.
To sum up from links posted in this thread numerous times alrady for those that seems to not be abel to keep informed and conceptualise what have happened and what is happening in the UHD "realm":
Eutelsat started regular
UHD satellite transmissions January 8, 2013."Eutelsat’s new channel is designed to benefit all actors in the broadcasting chain who want to acquire expertise in 4K, including production companies, pay-TV operators, rights owners and TV set manufacturers.
The new channel will operate in progressive mode at 50 frames per second.
It will be encoded in MPEG-4 and transmitted at 40 Mbit/s in four Quad HD streams.
Eutelsat is partnering with ATEME, a video compression solution provider to the broadcast industry, for the transmissions that will be uplinked to the EUTELSAT 10A satellite from its teleport in Rambouillet, near Paris."
The first 8K satellite test transmission was done in 2008, and Eutelsat won an award for this."At the 2008 IBC in Amsterdam, Eutelsat, a partner of the “Broadcast Technology Futures Group”, received the “IBC 2008 Special Award” for the first worldwide Super Hi-Vision satellite 8K transmission."
HEVC implementation will also make it possible to transmit more content par transponder than what is done today.
Several companies are already using early HEVC versions on existing equipment for testing while they wait for the "finished" HEVC version."With the new HEVC and probably the DVB-S3 standards, we should be able to transmit around 5 UHD 4K channels at 50 fps per 36MHz transponder, with a bit rate per channel a little higher than one current MPEG4 HDTV channel, but with a double frame rate (50 fps instead of 25) for a better viewing experience."
All this have been posted in this thread numerous times already. Please keep updated to prevent this thread to go in endless circles.
AS for the people here that seem to not understand that HEVC compression bitrates does not equal the effect of H.264 compression bitrates when it comes to image quality effects. Try rather to understand the difference than argue on the basis that it is equal."HEVC introduces a number of additional tools to exploit spatial and temporal redundancy, including enhanced motion compensated filtering, multiple coding block sizes, increased coding unit block sizes (from 8×8 to 64×64),
hierarchical block coding, advanced motion vector prediction,
improved context adaptive binary arithmetic coding (CABAC) processing,
expanded loop filters (de-blocking, sample adaptive offset, and adaptive loop filter),
and optimised intra-frame prediction.
One feature that may specifically benefit satellite operators is HEVC’s ability to more efficiently code larger block sizes, especially in regions where there is little change in the picture content.
By coding larger images, HEVC will allow operators to more easily support future 4K and 8K UHDTV services, which offer television viewers a much higher resolution picture quality.
Additionally, the HEVC standard optimises intra-frame prediction by combining spatial closed- and open-loop predictions to exploit redundancy within the current frame.
By exploiting redundancy not only between neighbouring blocks but also within a coding block itself, the new tool — called Combined Intra-Predication — offers more prediction directions than AVC, thereby increasing the efficiencies of video compression.
HEVC also resolves contouring artefacts that are visible in H.264/MPEG-4 AVC when coding flat or smooth image backgrounds.
Via an internal increase in precision (greater bit depth), HEVC can more accurately calculate the coding necessary for complex images, eliminating banding issues.
Future HEVC developments may include support for multi-view video coding or stereo 3D video combined with scalable video coding (SVC), allowing a video stream, sequence, or image to be represented in multiple ways and formats so that satellite operators can more efficiently prepare content in different resolutions, frame or bit rates, for viewing on any device, including TVs, smartphones, and tablets."
The only reason 8K is not a bigger part of the tests of this at the moment is that there are lack of original 8K material, 8K cameras and 8K displays.
HEVC will change that in the coming years.
