InterDigital Wins Best of Show for the Digital Double
InterDigital received the IBC Best of Show award, presented by TVB Europe for innovations and outstanding products in media and entertainment, for our cutting-edge “Digital Double” technology. Developed in InterDigital’s Immersive Lab, the Digital Double tool improves upon the traditionally time- and labor-intensive 3D avatar creation process to automatically create a person’s digital avatar in less than 30 minutes! Although the Digital Double technology completely automates the avatar creation process, it also gives users the option to make stops and manually finetune the avatar at each step. Using a rig of 14 cameras, the technology computes a full 3D mesh of a person’s face and upper body from the cameras’ images to create more human-like avatars and a precise set of facial expressions for animation.
The Best in Show award recognized the Digital Double’s potential to enhance immersive video opportunities of the future, where individuals could see themselves in real-time as a character in a film or on television or even virtually participate in a game show alongside a presenter, contestants, and audience on screen. The Digital Double technology started at the highest end of the market, this time in Hollywood film production, and is likely to eventually make its way into the consumer mainstream.
The Digital Double’s foundational facial animation control for expression transfer (FACET) technology has already been used by production companies like Disney and Paramount in blockbuster films such as the Jungle Book remake and the Shape of Water. We are excited to explore this award-winning tech’s applications in virtual reality, gaming, and other immersive experiences where an individual’s digital avatar can be adapted to each context.
InterDigital’s Contributions to Tech Innovation in the Digital Domain
In addition to the Digital Double technology, InterDigital’s Research and Innovation teams displayed 5G their advanced research to support next generation and future video streaming capabilities. Laurent Depersin, Director of the InterDigital R&I Home Experience Lab, provided an overview of InterDigital’s contributions to video innovations during a panel discussion on “Technological Innovation in the Digital Domain.” Laurent spoke alongside peers from VoiceInteraction and Haivision, to explore the innovations needed to support high resolution and intensive data applications for the video content of the future. You may view Laurent’s panel discussion here.
During his presentation, Laurent outlined new video applications that drive the need for technological innovation, as well as InterDigital’s Home Experience Lab’s commitment to develop technologies that both connect and improve user experience in the home. Laurent identified mass increases in video consumption, the popularity of interactive and immersive content like VR and gaming, and the trend towards ultra-high bandwidth and ultra-low latency content in the form of immersive communication and 8K video, as the key drivers of InterDigital’s innovative work in video technology.
Versatile Video Coding: Improving on the High-Efficiency Video Coding (HEVC) Standard
5G InterDigital’s demonstration on Versatile Video Coding (VVC), presented by Michel Kerdranvat and Imaging Science Lab Director Lionel Oisel, reflects our work to develop cutting-edge tools that analyze, process, present, compress, and render content to improve the production and delivery of high-quality images.
The InterDigital R&I lab’s contribution to the VVC standard enhances the video compression efficiency of the existing High-Efficiency Video Coding (HEVC) standard published in 2013. Specifically, its demonstration compared the HEVC and VVC video standards and showed how VVC can compress and improve video delivery by lowering the bandwidth and bitrate required for Standard Dynamic Range (SDR), High Dynamic Range (HDR) and immersive, 360-degree video content.
The Need for Point Cloud Compression for Immersive Video
The InterDigital Imaging Science Lab’s demo on Point Cloud Compression, presented by Céline Guede and Ralf Schaefer, built upon the HEVC video coding standard to showcase the vital need for video compression mechanisms to enjoy increasingly immersive and interactive video experiences in VR, AR, and 3D imagery.
Point Clouds are sets of tiny “points” grouped together to make a 3D image. Point Cloud has become a popular method for AR and VR video composition, 3D cultural heritage and modeling, and geographic maps for autonomous cars. While this method has many benefits, it is important to remember that each Point Cloud video frame typically has 800,000 points, which translates to 1,5000 MBps uncompressed – a massive amount of video bandwidth. To address this challenge, our Imaging Science Lab has participated in the development of a Point Cloud Compression method being standardized in MPEG to support widespread industry adoption of the Point Cloud format for immersive video. InterDigital showcased its video-based Point Cloud Compression capabilities in a Point Cloud-created AR video demo streamed to a commercially available smartphone in real time. This technique will support the crisp, low-latency deployment of immersive video experiences through existing network infrastructure and devices.
The Challenges and Potential for Volumetric Video
In concert with our efforts to compress and deliver high bandwidth video, InterDigital R&I’s Immersive Lab also demonstrated its innovative work to enhance immersive experiences that meet our interactive media demands. To give context to the importance of its technological contributions, Immersive Lab Technical Area Leader Valérie Allié delivered a presentation on the challenges and potential of volumetric video and the various applications in which it might be deployed.
Valérie Allié delivers a presentation on the opportunities of volumetric video content
Volumetric video is hailed as the next generation of video content where users can feel the sensations of depth and parallax for more natural and immersive video experiences. As AR, VR, and 3D video become a more mainstream consumer demand, providers will require tools to deliver the metadata necessary to produce a fluid, immersive or mixed reality video experience from the perspective of each viewer. As a result, content providers may face challenges in maintaining high video quality while supporting user viewpoint adaptation and low latency.
MPEG Metadata for Immersive Video: A Roadmap for Volumetric Video Distribution
Valérie Allié and Julian Fleureau’s demo on MPEG Metadata for Immersive Video outlined both the steps to create volumetric video and the requisite format for its distribution. Unlike flat 2D video experiences, volumetric video is much larger and cannot be streamed over traditional networks. In addition, volumetric video requires the capture of real video through camera rigs, the development of computer-generated content, the creation of a composite film sequence using VFX tools, and the interpolation of a video’s view to create a smooth, unbroken rendering of immersive content from the user’s point of view.
Addressing the Challenges of Six Degrees of Freedom (6DoF) Streaming
Visitor experiences InterDigital's 6DoF streaming video capabilities on a VR Headset
The significance of the MPEG codec for immersive and volumetric video was put on display in the InterDigital R&I Home Experience Lab’s Six Degrees of Freedom (6DoF) streaming demo, presented by Charline Taibi and Rémi Houdaille. 6DoF refers to the six movements of a viewer in a 3D context, including heave for up and down movements, sway for left and right movements, surge for back and forward movements, yaw for rotation along the normal axis, pitch for rotation along the transverse axis, and roll for rotation along the longitudinal axis.
Using a computer-generated video streamed through a VR headset, the demonstration showed how the standards and codecs developed by InterDigital’s labs can be utilized to stream fully immersive volumetric video with six degrees of freedom over current network infrastructure.
The demonstration achieved a seamless and immersive experience by streaming only content from the viewers’ point of view.
InterDigital left a lasting impression on all who visited our IBC booth and networking hub and experienced the Research and Innovation Labs’ innovative demos. We are excited to play a role in the pioneering compression solutions and streaming capabilities that will drive and enable the immersive video experiences of the future.
