Using a collection of publicly available links to short form video clips of an average of 6 seconds duration each, 1,275 users manually annotated each video multiple times to indicate both longterm and short-term memorability of the videos. The annotations were gathered as part of an online memory game and measured a participant’s ability to recall having seen t…

The arrival of YouTube in 2005, followed by Apple’s first iPhone in 2007, and Google’s Android platform in 2008, serves as the preamble to what has become a two-screen video market. A decade and a half might seem like a long period of time, but put into context of television’s history, it is a remarkably short timeframe. Color TVs, for example, arrived in 1953, …

Video compression is a key technology for new immersive media experiences, as the percentage of video data in global Internet traffic (80% in 2019 according to the 2018 Cisco Visual Networking Index report) is steadily increasing. The requirement for higher video compression efficiency is crucial in this context. For several years intense activity has been obser…
An examination of the value chain that drives video is necessary to understand and examine the future of video distribution. Operators, broadcasters or platforms that either produce or aggregate content, pay for video distribution with revenues generated directly by consumers or via advertising. In the past five years, consumer expectation for content and total …

This paper proposes an adaptive volumetric video streaming platform including real-time tracking, adaptive source view selection, DASH streaming, GPU accelerated view synthesis, HEVC decoding and view-dependent rendering. Volumetric use case supports 3 degree of freedom immersive experience with additional limited translational movement. The proposed adaptive st…
Video codecs play an integral, yet often underappreciated, role in digital video. Since the 1980s, they have remained a crucial but sometimes overlooked element of the software stack. The most successful persist in the market for a long time, enjoying a lifespan in excess of 20, or even 30, years.
Video services traffic over the internet has drastically grown these past years, currently representing more than 80% of the internet bandwidth [1]. The massive usage of unicast delivery leads to network congestion that can result in poor quality of experience for the viewer, high delivery cost for operators and increased energy consumption. In addition, the cur…

The world has witnessed significant change since the dawn of the industrial revolution. Life expectancy has more than doubled; travel across the planet can happen in less than a day; loved ones can be reached via a video screen and vast quantities of information can be accessed at the touch of a button. But as our quality of life, and the science and technology …

Deep neural networks have been recently proposed to solve video interpolation tasks. Given a past and future frame, such networks can be trained to successfully predict the intermediate frame(s). In the context of video compression, these architectures could be useful as an additional inter-prediction mode. Current inter-prediction methods rely on block-matching…

We propose in this paper a new paradigm for facial video compression. We leverage the generative capacity of GANs such as StyleGAN to represent and compress a video, including intra and inter compression. Each frame is inverted in the latent space of StyleGAN, from which the optimal compression is learned. To do so, a diffeomorphic latent representation is learn…

Versatile Video Coding (VVC) standard is currently being prepared as the latest video coding standard of the ITU-T and ISO/IEC. The primary goal of the VVC, expected to be finalized in 2020, is to further improve compression performance compared to its predecessor HEVC. The frame level, slice level or Wavefront parallel processing (WPP) existing in VTM (VVC Test…
This paper addresses the example-based stylization of videos. Style transfer aims at editing an image so that it matches the style of an example. This topic has recently been investigated massively, both in the industry and academia. The difficulty lies in how to capture the style of an image. For this work we build on our previous work " Split and Match " for s…
