Video coding is an essential component of video streaming, digital TV, video chat and many other technologies. This presentation, an invited lecture to the US Patent and Trade Mark Office, describes some of the key developments in the history of video coding. Many of the components of present-day video codecs were originally developed before 1990. From 1990 onwards, developments in video coding were closely associated with industry standards such as MPEG-2, H.264 and H.265/HEVC. The presentation covers: - Basic concepts of video coding - Fundamental inventions prior to 1990 - Industry standards from 1990 to 2014 - Video coding patents and patent pools.

The tutorial covers the complete HEVC standard, including all currently defined extensions (range extensions, scalability, multi-view, 3D video coding, and screen content coding). It further covers the state of the current activities on Free-Viewpoint Television and on High Dynamic Range + Wide Color Gamut Coding. The standard is assessed from various perspectives, including an algorithmic view on the video coding layer as well as a high-level / system-layer view on the network abstraction layer and the overall structure. The discussion includes a detailed treatment of the HEVC layer concept which allows for seamless incorporation of spatial and quality scalability as well as multi-view, 3D, or FTV extensions. The essential concepts and the coding tools comprised in each of the extensions are detailed and explained in the context of their respective application space. The tutorial further discusses the basic structure of specification text from a more abstract point of view as well as by concrete example in HEVC. For all mentioned perspectives, the tutorial develops the topic in a step-by-step fashion and gradually introduces concepts, algorithms, and terminology. Examples are provided at all levels of the presentation illustrating the concepts and deepening the understanding of the presented technology. Various demos are presented to visualize the algorithmic advancement. The tutorial is based on the book “High Efficiency Video Coding: Coding Tools and Specification” by the tutorial speaker which currently covers HEVC version 1. The tutorial shall enable the participants to understand the design principles and concepts behind the specification of HEVC. They shall recognize and understand the innovation of HEVC compared to the previous standards (esp. H.264/AVC) and regard the extensible nature of the specification design.

Encoding at Scale for Live Video Streaming

Ray Adensamer

Many of today’s live video encoding solutions require extensive compute resources, limiting the ability of live streaming business models to economically scale. This session, presented at Streaming Media West 2018, will introduce a new real-time video encoding solution, combining the performance of System-on-Chip (SoC) encoding, with innovations from NVMe-based cloud infrastructure, which together provides an economical and high quality solution to deliver encoding at scale for live video streaming.

WebRTC and the Codec War

Weemo, Inc.

The codec war is raging now more than ever before. The increased popularity of the proposed WebRTC protocol and the implied royalty costs make this a hot topic. Google, Cisco, Microsoft and now finally Apple are promoting their preferred technology and attempting to influence the choice to be made for WebRTC. The choice is far from clear especially in light of the latest technology advances, the transcoding infrastructure costs involved and the impact on mobile devices. In this session, Weemo will share its multi-year experience developing on top of the leading video and voice codecs. The speaker will provide some perspective on the advantages of each across devices taking into account hardware and software based video acceleration and the impact each have on the end user.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert

In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development. This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
