  • Why “Not- Compressing” Simply Doesn't Make Sens ?
    WHY “NOT- COMPRESSING” SIMPLY DOESN’T MAKE SENS ? Confidential IMAGES AND VIDEOS ARE LIKE SPONGES It seems to be a solid. But what happens when you squeeze it? It gets smaller! Why? If you look closely at the sponge, you will see that it has lots of holes in it. The sponge is made up of a mixture of solid and gas. When you squeeze it, the solid part changes it shape, but stays the same size. The gas in the holes gets smaller, so the entire sponge takes up less space. Confidential 2 IMAGES AND VIDEOS ARE LIKE SPONGES There is a lot of data that are not bringing any information to our human eyes, and we can remove it. It does not make sense to transport, store uncompressed images/videos. It is adding data that have an undeniable cost and that are not bringing any additional valuable information to the viewers.

  • Overview of Mpeg-5 Part 2 – Low Complexity
    ITU Journal: ICT Discoveries, Vol. 3(1), 8 June 2020 OVERVIEW OF MPEG-5 PART 2 – LOW COMPLEXITY ENHANCEMENT VIDEO CODING (LCEVC) Florian Maurer1, Stefano Battista2, Lorenzo Ciccarelli3, Guido Meardi3, Simone Ferrara3 1RWTH Aachen University, Germany, 2Università Politecnica delle Marche (UNIVPM), Italy, 3V-Nova, UK Abstract – This paper provides an overview of MPEG-5 Part 2 Low Complexity Enhancement Video Coding (LCEVC), a novel video coding standard from the MPEG ISO Working Group. The codec is designed for use in conjunction with existing video codecs, leveraging specific tools for encoding "residuals", i.e. the difference between the original video and its compressed representation. LCEVC can improve compression efficiency and reduce the overall computational complexity using a small number of specialized enhancement tools. This paper provides an outline of the coding structure of encoder and decoder, coding tools, and an overview of the performance of LCEVC with regard to both compression efficiency and processing complexity. Keywords – Low Complexity Enhancement Video Coding (LCEVC), MPEG-5 Part 2, multi-resolution video coding, video compression. 1. INTRODUCTION is the case, changing codecs cannot be done without relevant up-front investments and large amounts of This paper provides an overview of MPEG-5 Part 2 time. Accordingly, having the possibility to upgrade Low Complexity Enhancement Video Coding an ecosystem without the need to replace it (LCEVC), a new video coding standard developed by completely and still having the freedom to select a MPEG that is scheduled to be published as base codec of their choice is an important option ISO/IEC 23094-2 [1]. that operators need to have.

  • V-Nova LCEVC XDE / XSA Ultra-Density Video Encoding
    V-Nova LCEVC XDE / XSA Ultra-density Video Encoding • Increase throughput by up to 4x: 4Kp60 or multiple HD streams per card • Deliver higher quality at up to 50% lower bitrates • Simple deployment for existing or new encoding operations INTRODUCTION Hyperscale video services like social and e-sports networks need to encode and serve vast numbers of streams to their users. The server infrastructure required to satisfy this demand is often the largest cost for these businesses. V-Nova LCEVC running on Xilinx FPGA enables any service operating private cloud to radically transform their efficiency, reducing operating costs by up to 4x whilst improving the streaming quality-of-service for their users. Furthermore, public or private clouds can deploy LCEVC on Xilinx® AlveoTM Data Center accelerator cards as an ultra-dense encoding solution to offer significant quality and cost benefits to their video delivery customers. V-Nova LCEVC is the industry’s first optimised software for the MPEG-5 “Low Complexity Enhancement Video Coding” standard. LCEVC is the first enhancement standard and significantly improves the quality and throughput of any existing or future codec (e.g. AVC/H.264, HEVC, VP9, AV1, VVC, EVC). When combined with a Xilinx FPGA, V-Nova LCEVC provides the highest density encoding solution in the market enabling use cases such as live 4Kp60 encoding on a single card. Playback is supported on a broad range of devices as LCEVC leverages the hardware decoding capabilities of the underlying codec already present. PRODUCT OVERVIEW Xilinx FPGA support V-Nova LCEVC in two available configurations: • V-Nova LCEVC XSA is a single board FPGA acceleration solution providing up to 4x throughput increase on existing codec deployments, whether in software or in hardware.

  • The VC-6 Overview Whitepaper Mrmxf.Com/White-Paper by Mr MXF for V-Nova a New Compression Technology Is Required for This New Era in Media Technology
    Mr MXF Ltd The VC-6 Overview Whitepaper mrmxf.com/white-paper by Mr MXF for V-Nova A new compression technology is required for this new era in media technology. Novel workflows mixing smaller cheaper devices and advanced software that is often cloud based make the requirements of moving bulky imagery more complex and more nuanced. Couple these with new service oriented business models that allow billing per file that is based on size and resources consumed and you end up with the need for a codec that can be locally optimised on a workflow by workflow basis. We need a high quality video encoder that can extend its range from lossless to high compression ratios. It must be easy to compute, easy to scale in software it must be implemented in repeatable functional blocks in hardware, it must be synergistic with Machine Learning processes, it must be natively multi-resolution, it must be cloud friendly, energy efficient, available now AND an international standard. This white paper explores some of the facts and functionality behind SMPTE ST 2117-1 VC-6 is different Figure 1 - JPEG2000 vs VC-6 VC-6 shares many features of other coding schemes but also has significant difference. The figure above shows a comparison with JPEG2000 (J2K). Planes: VC-6 codes the original planes of the image to ensure there is not chance of mathematical error. J2K converts to a luminance plane and color difference planes. This improves . compression ratio but requires two different color transforms - one for lossy and a different one for lossless compression.

  • 12Th SMPTE EMERGING TECHNOLOGIES SEMINAR Thursday 15Th April 2021 – 15:00~18:00 Forum Europeo Digitale – Digital Edition ______
    22nd MAR 2021,update 12th SMPTE EMERGING TECHNOLOGIES SEMINAR Thursday 15th April 2021 – 15:00~18:00 Forum Europeo Digitale – Digital Edition ______________________________________________________________ The Italian Section of SMPTE, Society of Motion Picture and Television Engineers, is pleased to announce its twelfth Seminar dedicated to the Emerging Technologies. Following the success of the previous Seminars, SMPTE has deemed it appropriate to follow up on this consolidated initiative to fulfill its statutory mission which concerns the issue and dissemination of international technical standards governing the technologies of the moving image. This event is kindly hosted in the context of the European Digital Forum, which this year will be presented as online digital edition, will take place on April 15, 2021 starting at 15:00 and ending by 18:00 with the participation of international qualified experts. WORKSHOP PURPOSE The last twenty years have seen the achievement of a goal that television had set itself since its inception: to equal and exceed with video images the quality of the cinematic image on film which, in the first decades of the last century, had established itself as great media innovation in a rapidly evolving communication context. This ambition clearly emerged in 1980, when Dr. Takashi Fujio, director of the Research Laboratories of NHK (the Japanese public broadcaster) proposed an analog television standard for an "electronic film" named Hi-Vision: it was the first High Definition system that promised to improve the video image by focusing on increasing its spatial resolution (determined by the number of raster lines and the bandwidth of the video signal itself).
