IBC displays the screens of tomorrow

IBC displays the screens of tomorrow | Audiovisual Interaction | Scoop.it

Delegates to this year’s IBC expo in Amsterdam have been able to sample a variety of future displays and file formats, among them an improved Super Hi-Vision.


The NHK-backed Super Hi-Vision is a project familiar to RAI attendees and one the Japanese broadcaster and its industry partners have been been working on since the beginning of the Millennium.


The year-to-year advances have been plain to see. The Sharp prototype 85″ 8K LCD displays clearly performed much better than the ones shown only last year.


A further improvement on show this year was the doubling of Ultra High Definition (UHD) or Super Hi-Vision (SHV)’s frame rate. The side-by-side demo in the show’s Future Zone was so obvious, from completely blurred fast-moving pans on one screen to a very watchable version shot with the 120 frames per second version from NHK’s 8K camera.


UHDTV was ratified by the ITU earlier this year in both the original 60 fps and the 120 fps variety. The demo at this year’s Future Zone, next to hall 8, makes clear that 120 frames per second is an acceptable starting point.

J'apprécie déjà grandement la HD actuelle (FullHD) je suis vraiment curieux de rencontrer ce type de diffusion notamment en cinéma par exemple :)

Surtout que les premiers retours que j'ai lu sur l'UHD parlent d'un "sentiment de 3D" très impressionnant ! D'ailleurs un article avait été présenté ici même ( BBC favours Super Hi-Vision over 3D )

HEVC : The compression technology promises to optimize OTT and UHDTV delivery

HEVC : The compression technology promises to optimize OTT and UHDTV delivery | Audiovisual Interaction | Scoop.it

As consumers increasingly view live and VOD television on a broader range of IP-connected devices, broadcasters are struggling to deliver these high-bandwidth services. However, a new video compression standard called High Efficiency Video Coding (HEVC) promises to improve upon the current compression standard H.264, also known as MPEG-4 AVC, easing broadcasters’ pain. Using HEVC, broadcasters can reduce the data rate needed for high-quality video coding by approximately 50 percent, enabling them to deploy higher quality OTT video services using the same amount of bandwidth, or half the bandwidth at the same quality. In addition to improving OTT delivery, HEVC also has the potential to support a broad range of current and future applications, including 4K x 2K Ultra High Definition Television (UHDTV), making it an extremely exciting technology that pushes the consumer experience to the next level.

Quand je vois encore des services actuels fonctionner en codec MPEG2 j'me dis que la priorité des créateurs de services n'est pas forcément là où on pense :D

HEVC is going to be big, Especially for OTT, that bypasses operators, direct connection between contentb and devices. Then operators will start to enjoy :)

Ultra HD TV: the future of 2D TV in two parts

Ultra HD TV: the future of 2D TV in two parts | Audiovisual Interaction | Scoop.it

"The next - maybe final - stage of high definition 2D TV will be delivered in two stages that will boost today’s HD to the limit of human eyesight.

 

HDTV today has settled around images that are 1,920 pixels across and 1,080 pixels high, but Ultra HD TV will be 7,680 pixels by 4,320 pixels.

 

The International Telecommunications Union, which sets standards for broadcasters worldwide, has settled on a two-step introduction of Ultra HD."
