There is currently the widest breadth of video codecs available for the massive $200B video services industry, comprising broadcast, streaming, and other services, in history: MPEG-2, MPEG-4, AVC, HEVC, VVC, VP8, VP9, AV1, EVC, and LC-EVC. While these codecs compete in the marketplace for share of streams, the consumer surely benefits from having advanced services at lower rates. Is 4K HDR HEVC going to become the new norm for broadcast/streaming? But this is a challenging environment for developers and service provides. In this panel, we explore the breadth of consumer services that are enabled by these technologies, including high resolution: 4K, 8K, and beyond, as well as HDR, and AR/VR – will these finally take off and fulfill their promise? And is 8K the end of the line for consumer devices such as TVs, and even computers, tablets, and smartphones?
The MPEG-5 Essential Video Coding (EVC) Standard was finalized in July 2020 in ISO/IEC Moving Picture Experts Group (MPEG). The main goal of the EVC standard development was to provide a significantly improved compression efficiency over existing video coding standards with timely publication of licensing terms. To achieve the goal of project, the EVC standard was developed with the royalty-free based Baseline profile (BP) as its base and a royalty bearing Main profile having a small number of coding tools on top of the Baseline profile. This paper presents EVC BP which can be a strong candidate for the media application that is a dominant in the internet platform. To evaluate the coding performance of the EVC BP, the testing result compared to H.264/AVC is provided. In the testing result, the EVC BP has shown 31.2% and 30.4% bitrate reductions with using only 40% and 23% encoding times of H.264/AVC under RA and LD test scenarios, respectively.
MPEG-5 Essential Video Coding Standard is currently being prepared as the video coding standard of ISO/IEC Moving Picture Experts Group. The main goal of the EVC standard development is to provide a significantly improved compression capability over existing video coding standards with timely publication of availability terms. This paper provides an overview of the feature and the characteristics of the MPEG-5 EVC standard.
Joint Exploration Model (JEM) studies the next generation video coding standard potential. It demonstrates over 30% performance gain beyond HEVC. This paper provides tool-on and tool-off performance test results for 24 methods included into JEM. Overlap in the functionalities of those tools is discussed. Potential problems for mobile platform implementation are listed. Suggestion on standard development principals and tools selection for next generation video coding standard are made. Paper is intended to assist high quality Call for Proposal responses preparation.
In this paper, several coding tools are evaluated on top of the HEVC version 1. Among them there are straightforward extension of HEVC coding tools (such as Coding Unit size enlarging, fine granularity of Intra prediction angles) and algorithms that have been studied during HEVC development (such as secondary transform, multi-hypothesis CABAC, multi-parameter Intra prediction, bidirectional optical flow). Most of them improve performance of Intra coding. Minor adjustment to the final version of HEVC standard was done for efficient harmonization of the proposed coding tools with HEVC. Performance improvement observed from investigated tools is up to 7,1%, 9,9%, 4,5% and 5,7% in all-intra, random access, low-delay B and low-delay P test scenario (using HEVC common test conditions).
