8K Live Television Coverage of Global Sports Events in Brazil
8K Live Television Coverage of Global Sports Events in Brazil Michael Stanton1, Leandro Ciuffo1, Shinichi Sakaida2, Tatsuya Fujii3, Hiroyuki Kimiyama3, Junichi Nakagawa4, Hisao Uose5 1 Rede Nacional de Ensino e Pesquisa (RNP), Brazil 2 Science and Technology Research Laboratories, Japan Broadcasting Corporation (NHK), Japan 3 Network Innovation Laboratories, Nippon Telegraph and Telephone Corporation (NTT), Japan 4 Service Evolution Laboratories, Nippon Telegraph and Telephone Corporation (NTT), Japan 5 NTT Advanced Technology Corporation (NTT-AT), Japan e-mails: [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] Paper type Case study Abstract R&E networks played an important role in helping Japanese television to transmit live 8K resolution TV images of the 2014 FIFA World CupTM to Japan. The huge distance between Brazil and Japan, half a world apart, set new challenges for streaming digital video spanning multiple domains over long-distance networks. The project to stream the FIFA World CupTM in 8K was a joint collaboration between NHK (Japanese Public Broadcasting Corporation), TV Globo (Brazilian TV broadcaster), NTT (Japanese Telecommunications Corporation) and RNP (Brazilian NREN), in cooperation with FIFA and CBPF (Brazilian Centre for Physics Research). The paper describes the audio and video technologies used in 2014, as well as the extensive preparations for efficient and effectively lossless media transmission over the intermediate networks. The high-compression H.264 codec developed by NHK required 280 Mbps for compressed SHV media transmission. In addition, the transmitted media were encrypted (for security), and then protected against packet loss by use of FireFort-LDGM FEC, a new forward error correction (FEC) code based on low- density generator matrix (LDGM), developed by NTT. -
Ultra HD Playout & Delivery
Ultra HD Playout & Delivery SOLUTION BRIEF The next major advancement in television has arrived: Ultra HD. By 2020 more than 40 million consumers around the world are projected to be watching close to 250 linear UHD channels, a figure that doesn’t include VOD (video-on-demand) or OTT (over-the-top) UHD services. A complete UHD playout and delivery solution from Harmonic will help you to meet that demand. 4K UHD delivers a screen resolution four times that of 1080p60. Not to be confused with the 4K digital cinema format, a professional production and cinema standard with a resolution of 4096 x 2160, UHD is a broadcast and OTT standard with a video resolution of 3840 x 2160 pixels at 24/30 fps and 8-bit color sampling. Second-generation UHD specifications will reach a frame rate of 50/60 fps at 10 bits. When combined with advanced technologies such as high dynamic range (HDR) and wide color gamut (WCG), the home viewing experience will be unlike anything previously available. The expected demand for UHD content will include all types of programming, from VOD movie channels to live global sporting events such as the World Cup and Olympics. UHD-native channel deployments are already on the rise, including the first linear UHD channel in North America, NASA TV UHD, launched in 2015 via a partnership between Harmonic and NASA’s Marshall Space Flight Center. The channel highlights incredible imagery from the U.S. space program using an end-to-end UHD playout, encoding and delivery solution from Harmonic. The Harmonic UHD solution incorporates the latest developments in IP networking and compression technology, including HEVC (High- Efficiency Video Coding) signal transport and HDR enhancement. -

JPEG-HDR: a Backwards-Compatible, High Dynamic Range Extension to JPEG
JPEG-HDR: A Backwards-Compatible, High Dynamic Range Extension to JPEG Greg Ward Maryann Simmons BrightSide Technologies Walt Disney Feature Animation Abstract What we really need for HDR digital imaging is a compact The transition from traditional 24-bit RGB to high dynamic range representation that looks and displays like an output-referred (HDR) images is hindered by excessively large file formats with JPEG, but holds the extra information needed to enable it as a no backwards compatibility. In this paper, we demonstrate a scene-referred standard. The next generation of HDR cameras simple approach to HDR encoding that parallels the evolution of will then be able to write to this format without fear that the color television from its grayscale beginnings. A tone-mapped software on the receiving end won’t know what to do with it. version of each HDR original is accompanied by restorative Conventional image manipulation and display software will see information carried in a subband of a standard output-referred only the tone-mapped version of the image, gaining some benefit image. This subband contains a compressed ratio image, which from the HDR capture due to its better exposure. HDR-enabled when multiplied by the tone-mapped foreground, recovers the software will have full access to the original dynamic range HDR original. The tone-mapped image data is also compressed, recorded by the camera, permitting large exposure shifts and and the composite is delivered in a standard JPEG wrapper. To contrast manipulation during image editing in an extended color naïve software, the image looks like any other, and displays as a gamut. -

JPEG Compatible Coding of High Dynamic Range Imagery Using Tone Mapping Operators
JPEG Compatible Coding of High Dynamic Range Imagery using Tone Mapping Operators Min Chen1, Guoping Qiu1, Zhibo Chen2 and Charles Wang2 1School of Computer Science, The University of Nottingham, UK 2Thomson Broadband R&D (Beijing) Co., Ltd, China Abstract. In this paper, we introduce a new method for HDR imaging remain. For example, to display HDR compressing high dynamic range (HDR) imageries. Our images in conventional CRT or print HDR image on method exploits the fact that tone mapping is a necessary paper, the dynamic range of the image has to be operation for displaying HDR images on low dynamic compressed or the HDR image has to be tone mapped. range (LDR) reproduction media and seamlessly Even though there has been several tone mapping integrates tone mapping with a well-established image methods in the literature [3 - 12], non so far can compression standard to produce a HDR image universally produce satisfactorily results. Another huge compression technique that is backward compatible with challenge is efficient storage of HDR image. Compared established standards. We present a method to handle with conventional 24-bit/pixel images, HDR image is 96 color information so that HDR image can be gracefully bits/pixel and data is stored as 32-bit floating-point reconstructed from the tone mapped LDR image and numbers instead of 8-bit integer numbers. The data rate extra information stored with it. We present experimental using lossless coding, e.g, in OpenEXR [15], will be too results to demonstrate that the proposed technique works high especially when it comes to HDR video.
