New H.266/VVC codec improves efficiency by 50%

After devoting several years to its research and standardization, Fraunhofer HHI, together with partners including Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm, and Sony, announced the release of H.266/Versatile Video Coding (VVC).

The new H.266/VVC global video coding standard reduces bandwidth requirements by around 50% relative to the previous standard H.265/High Efficiency Video Coding (HEVC) without compromising visual quality.

H.266/VVC provides efficient transmission and storage of all video resolutions from SD to HD up to 4K and 8K, while supporting high dynamic range video and omnidirectional 360° video.

Fraunhofer HHI said H.266/VVC represents the pinnacle of (at least) four generations of international standards for video coding. The previous standards H.264/Advanced Video Coding (AVC) and H.265/HEVC, which were produced with substantial contributions from Fraunhofer HHI, remain active in more than 10 billion end devices, processing over 90% of the total global volume of video bits.

As an example of improved efficiency, the previous standard H.265/HEVC requires ca. 10 gigabytes of data to transmit a 90-min UHD video. H.266/VVC requires only 5 gigabytes of data to achieve the same quality. Because H.266/VVC was developed with ultra-high-resolution video content in mind, the new standard is particularly beneficial when streaming 4K or 8K videos.

“After dedicating almost three years toward this standard, we are proud to have been instrumental in developing H.266/VVC," says Benjamin Bross, head of the Video Coding Systems group at Fraunhofer HHI and editor of the +500-page standard specification of H.266/VVC. “Because of the quantum leap in coding efficiency offered by H.266/VVC, the use of video will increase further worldwide. Moreover, the increased versatility of H.266/VVC makes its use more attractive for a broader range of applications related to the transmission and storage of video.”

"If you consider that Fraunhofer HHI already played a key role in the development of the previous video coding standards H.264/AVC and H.265/HEVC, then we are happy with the fact that more than 50% of the bits on the Internet are generated by a Fraunhofer HHI technology,” adds Dr. Detlev Marpe, head of the Video Coding and Analytics department at Fraunhofer HHI.

A uniform and transparent licensing model based on the FRAND principle (i.e., fair, reasonable, and non-discriminatory) is planned to be established for the use of standard essential patents related to H.266/VVC.

Radisys Brings Enhanced Voice Services Codec to Mobile Operators

Radisys has added Ultra HD Enhanced Voice Services (EVS) audio codec support to its MediaEngine Media Resource Function (MRF).

By leveraging the new EVS codec, mobile operators can use less spectrum to deliver HD Audio or can deliver Ultra HD Audio using the same spectrum required for HD Audio. In addition, advanced error resilience built into EVS makes it ideal for VoLTE, delivering the same voice quality as AMR wideband while using less bandwidth – even in the face of up to 3x more packet loss.

The company confirmed that it has been working with a leading mobile operator in the deployment of Voice over LTE (VoLTE) to roll out Ultra HD Audio to its subscriber base.

“At Radisys, we’re laser focused on helping mobile operators solve the tough challenges of next-gen networks, including how to solve the problem of scarce spectrum,” said Grant Henderson, vice president, MediaEngine and Corporate Marketing, Radisys. “By adding EVS codec support to our MediaEngine solution, we’ve provided mobile operators with an important tool to make their existing spectrum more efficient and to deliver an Ultra HD Audio experience.”

Alliance for Open Media Targets Open Source Video Codec

The Alliance for Open Media, which was launched last year with the goal of developing an open standard for video compression and delivery over the web, has just added AMD, ARM and NVIDIA to its ranks.

The AOMedia consortium already included Amazon, Cisco, Google, Intel, Microsoft, Mozilla and Netflix.

The Alliance is also announcing public availability of its AOMedia Video source code as an open source project, and is welcoming contribution from the broader developer community.

"The open source availability of our AOMedia Video project with active contributions from industry leaders marks the beginning of a new era of openness and interoperability for Internet video," said Gabe Frost, Executive Director, the Alliance for Open Media. "We’re delighted to welcome AMD, ARM, and NVIDIA to the Alliance for Open Media, reflecting the importance of hardware support to achieve broad industry adoption.”

Radisys’ MPX-12000 MRF Delivers Cloud Conferencing for Zoom

Zoom Video Communications has deployed the Radisys MPX-12000 Broadband Media Resource Function (MRF) to provide scalable and reliable HD media processing for its cloud-based video conferencing service.  The solution is being used in Zoom's Santa Clara, California and New York, New York data centers.

The MPX-12000 Broadband MRF is based on Radisys’ telecom-grade T-Series platforms. It supports narrow and wideband audio codecs, including Adaptive Multi-Rate Wideband (AMR-WB) for Voice over LTE endpoints, G.722 for Voice over Wi-Fi, and Opus for WebRTC-based services. For video, it supports H.264, VP8, H.263 and MPEG-4 mobile codecs.

Our company is dedicated to providing high quality cloud collaboration services that are flexible, bullet proof and easy to consume,” said Eric S. Yuan, chief executive officer and founder, Zoom. “Our team was very familiar with Radisys’ leadership in VoIP conferencing having used them in prior solutions, and we knew they were well equipped to address our needs. By integrating Radisys’ MPX-12000 into our cloud infrastructure, Zoom is able to deliver significantly improved HD multi-media conferencing experiences for our customers.”
