Software repository; Scalable extensions of HEVC The source code for the software is available in the following SVN repository. https://hevc.hhi.fraunhofer.de/svn/svn_SHVCSoftware/ For tool integration branch for a company can be obtained by contacting: Seregin, Vadim (vseregin@qti.qualcomm.com) Build System The software can be built under Linux using make. For Windows, solutions for different versions of Microsoft Visual Studio are provided. Software Structure The SHVC Test Model Software inherits the same software structure from the HEVC test model HM software, which includes the following applications and libraries for encoding, decoding and down sampling process: Applications: TAppEncoder, executable for bit stream generation TAppDecoder, executable for reconstruction. TAppCommon, common functions for configuration file parsing. TAppDownConvert, down sampling functionalities. Libraries: TLibEncoder, encoding functionalities TLibDecoder, decoding functionalities TLibCommon, common functionalities TLibVideoIO, video input/output functionalities ATSC Advanced television systems committee www.atsc.org TV Tomorrow: ATSC 3.0 Advances ATSC 3.0 will be a radical departure from the current standard ATSC 1.0 was developed around 20 years ago, when cellphones were analog and streaming was unheard of. It relies 8-VSB modulation capable of delivering 19.39 Mbps in a 6MHz TV channel - enough to carry a high – definition program compressed by a factor of 50 using MPEG-2 to a fixed receiver. With ATSC 3.0, the committee seeks to increase that data rate by 30 percent, or roughly 25.2 Mbps. The overall intent of 3.0 is to enable seamless transmission of HD, 4K, 22.2 audio and other data streams to fixed, mobile and handheld devices in all types of terrain. The most differentiating characteristic of ATSC 3.0 is that it will not be backward – compatible with 1.0 or even 2.0, which is now in development. In other words, televisions now capable of processing over-the-air TV signals will not be able to
DAALA1 T.J. Daede et al, “A perceptually-driven next generation video codec” , IEEE DCC, Snow Bird, Utah, March-April 2016. Abstract of this paper is repeated here: The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR. This paper documents some of our experiences with these tools, which ones worked and which did not, and what we have learned from them. The result is a codec which compares favorably with HEVC on still images, and is on a path to do so for video as well. DAALA2 Daala test media," https://wiki.xiph.org/Daala Quickstart#Test Media. Daala Codec demo - Daala video compression Daala is the code-name for a new video compression technology. The effort is a collaboration between Mozilla Foundation, Xiph.Org Foundation and other contributors. The goal of the project is to provide a free to implement, use and distribute digital media format and reference implementation with technical performance superior to h.265.
