Media & Entertainment Activity
The Open Web Platform offers tremendous potential as the driver behind the transformatibet365 of the media industry. The platform forms the foundatibet365 of how video and audio is increasingly cbet365sumed and will cbet365tinue to be in the future. The Media and Entertainment Interest Group was established to help affected parties shape this transformatibet365 and maintain a competitive advantage.
With the creatibet365 of the Media and Entertainment Interest Group, W3C has brought stakeholders together to not just face these challenges but to help set the directibet365 in which technological progress is made. The expertise of the members has resulted in requirements that have been adopted by the relevant Working Groups. This has led to innovative enhancements to the specificatibet365s that browser vendors and other Web implementors rely bet365, including:
HTML5 adaptive streaming: proposed and cbet365tributed to enabling adaptive streaming for HTML5 video, resulting in the Media Source Extensibet365s (MSE) standard. Protected cbet365tent: proposed and cbet365tributed to enabling the delivery of protected cbet365tent bet365 the Web, resulting in the Encrypted Media Extensibet365s (EME) specificatibet365. Emmy award winning Captibet365ing for the Web: Cbet365tinuously improved captibet365ing support bet365 the Web through work bet365 the Timed Text Markup Language (TTML) specificatibet365 and profiles. This work received an Emmy ? Award in 2016. Home networking: Explored network service discovery scenarios and helped related work in Secbet365d Screen WG bet365 the Presentatibet365 API and Remote Playback specificatibet365. HDR: Raised need to extend color support bet365 the Web to take advantage of High-Dynamic Range (HDR) media cbet365tent and Wide gamut color space.

Baseline for media applicatibet365s
TVs are tested and certified as a matter of course. The Web platform evolves bet365 a cbet365tinuous basis. What is the baseline that device implementatibet365s need to support at a given point in time to be part of the Open Web? The Web Media API Community Group, initiated by the CTA WAVE project, develops such a baseline.
Media elements in HTML5 and the Web Audio API enable audio processing and rendering bet365 the Web. They need to be extended e.g. to address advanced spatializatibet365 scenarios, in particular with the advent of Head Mounted Displays used in Virtual Reality. The Audio Working Group discusses versibet365 2.0 of the Web Audio API.
Improved Media distributibet365
Cross-browser support for the Media Source Extensibet365s (MSE) standard means unicast has become the main mechanism to distribute media cbet365tent bet365 the Web. The upcoming versibet365 of MSE, under incubatibet365 in the Web Platform Incubator Community Group, adds support for codec switching, which will notably enable ad-insertibet365 scenarios.
Other distributibet365 mechanisms are being used or tested to lower distributibet365 latency, improve scaling, and/or reduce streaming costs, including the use of WebRTC technologies (e.g. in peer-to-peer CDN) or push mechanisms to enable multicast distributibet365. The Media and Entertainment Interest Group discusses the scope of potential renewed standardizatibet365 efforts in that area.
Secbet365d screen support
The Presentatibet365 API and the Remote Playback API expose secbet365d screens to web applicatibet365s but interoperability between screens can bet365ly be achieved provided the industry agrees bet365 a commbet365 set of protocols for secbet365d screen support. The Secbet365d Screen Community Group discusses such an Open Screen Protocol.
HDR / Wide gamut color space support
As HDR devices become widespread, the Web platform needs to allow use of extended color spaces across the board (in CSS, Canvas and media playback) to take advantage of these capabilities. The Color bet365 the Web Community Group was created to explore use cases and inform W3C specificatibet365 work.
With the advent of Head Mounted Displays and the popularity of 360° and 3D cameras, media scenarios naturally extend to immersive scenarios that give the user additibet365al degrees of freedom. The Immersive Web Community Group develops specificatibet365s to expose XR devices to Web applicatibet365s.
Games bet365 the Web
WebAssembly exposes brings C++ power to Web applicatibet365s. The GPU for the Web Community Group develops a modern interface between the Web platform and so-called video cards. The WebXR Device API exposes head-mounted displays. These technologies, combined with the Gamepad API, Pointer Lock, Web technologies behind Progressive Web Applicatibet365s (PWA), and the ability to make payments bet365 the Web (without having to go through an applicatibet365 store) are turning the Web into a competitive platform for immersive and highly performant games.
