SMPTE 2017: Next-Generation Video Compression Techniques
The accompanying technical manuscript for this presentation is available here: http://ieeexplore.ieee.org/document/8...
MPEG is working on requirements for a new video codec, which is expected to be completed by 2020. The future-generation codec will provide a 50 percent bitrate reduction compared with HEVC Main profile for the same perceptual quality. While this is sufficient for certain use cases, it may justify a future video coding standard for other applications that require bit rate reductions of more than 50 percent. This paper will look at the target applications for the new video codec, such as 8K, VR in 3DoF and 6DoF, the state of IP networks, and how network elements can potentially contribute to better compression via "Network Distributed Video Coding" (NDVC). Additionally, the paper will explore how new techniques can be used to reach a factor four compression compared with HEVC by 2020 using the next-generation MPEG codec. This is possible by leveraging content-aware encoding, elastic encoding, machine learning techniques, and pre/post processing pairing that uses metadata to signal how to post process video after decoding. To conclude, the paper will compare different approaches, including HEVC vs. HEVC boosted with NDVC techniques, as well as the JVET codec vs. NDVC methods.

SMPTE (pronounced "simp-tee"), the organization whose standards work has supported a century of advances in entertainment technology and whose membership spans the globe, holds the SMPTE Annual Technical Conference & Exhibition in Los Angeles each October. The event is considered the world's premier forum for the exploration of media and entertainment technology. More information about this year’s upcoming event is available at www.smpte2018.org.
The people of the Society of Motion Picture and Television Engineers, or SMPTE, have sorted out the details of many significant advances in media and entertainment technology, from the introduction of "talkies" and color television to HD and UHD (4K, 8K) TV. Since its founding in 1916, SMPTE has received an Oscar® and multiple Emmy® Awards for its work in advancing moving-imagery engineering across the industry. SMPTE has developed thousands of standards, recommended practices, and engineering guidelines, more than 800 of which are currently in force today. SMPTE Time Code™ and the ubiquitous SMPTE Color Bars™ are just two examples of SMPTE's notable work. As it enters its second century, SMPTE is shaping the next generation of standards and providing education for the industry to ensure interoperability as the industry evolves further into IT- and IP-based workflows. Visit www.smpte.org for more information.
SMPTE's global membership today includes more than 7,000 members: motion-imaging executives, creatives, technologists, researchers, and students who volunteer their time and expertise to SMPTE's standards development and educational initiatives. A partnership with the Hollywood Professional Association (HPA) connects SMPTE and its membership with the businesses and individuals who support the creation and finishing of media content. Information on joining SMPTE is available at www.smpte.org/join.
