The Open Web Platform is Transforming Television

The Open Web Platform offers tremendous potential as the driver behind the transformation of the TV industry. The platform forms the foundation of how video and audio is increasingly consumed and will continue to be in the future. The Web and TV Interest Group was established to help affected parties shape this transformation and maintain a competitive advantage.

The TV Industry is Shaping the Web at W3C

With the creation of the Web and TV Interest Group, W3C has brought stakeholders together to not just face these challenges but to help set the direction 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 specifications that browser vendors and other Web implementors rely on, including:

• HTML5 adaptive streaming: proposed and contributed to enabling adaptive streaming for HTML5 video, resulting in the Media Source Extensions (MSE) standard.
• Protected content: proposed and contributed to enabling the delivery of protected content on the Web, resulting in the Encrypted Media Extensions (EME) specification.
• TV tuner control in HTML5: Incubated the TV Control API specification and helped transition that work to the standardization track.
• Emmy award winning Captioning for the Web: Continuously improved captioning support on the Web through work on the Timed Text Markup Language (TTML) specification. This work received an Emmy ® Award in 2016.
• Home networking: Explored network service discovery scenarios and helped related work in Second Screen WG on the Presentation API specification.
• HDR: Raised need to extend color support on the Web to take advantage of High-Dynamic Range (HDR) media content and Wide gamut color space.

What's next for TV and the Web

• Baseline for media applications

  TVs are tested and certified as a matter of course. The Web platform evolves on a continuous basis. What is the baseline that device implementations 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.

• Audio support

  Media elements in HTML5 and the Web Audio API enable audio processing and rendering on the Web. They need to be extended e.g. to address advanced spatialization scenarios, in particular with the advent of Head Mounted Displays used in Virtual Reality. The Audio Working Group discusses version 2.0 of the Web Audio API.

• Hybrid media delivery support

  Users now want to mix traditional TV/radio broadcasting and over-the-top (OTT) content without having to think about it. How to expose hybrid delivery in as simple a way as possible both for end users and web app developers? Also, how to support broadcast-related applications that may be streamed with the broadcast signal? The TV Control Working Group exposes TV and radio tuners to applications.

• Second screen support

  The Presentation API and the Remote Playback API expose second screens to web applications but interoperability between screens can only be achieved provided the industry agrees on a common set of protocols for second screen support. The Second 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 on the Web Community Group was created to explore use cases and inform W3C specification work.

• Downloading and recording support

  Technical issues need to be overcome to balance the requirements of content providers and the desires of content consumers, including licensing and offline content protection.
