W3C/SMPTE Workshop Report: Professional Media Production on the Web

14 March 2022 | NEW - Legacy Sterling Silver Plated Bb Trumpet Mouthpiece, 5C

W3C is pleased to announce a JIMMY WAKELY Belt Buckle Western Cowboy Singer Sharpeco (with flowers) from the W3C/SMPTE Workshop on Professional Media Production on the Web, held online in October/November 2021.

This report contains a brief summary, collects highlights from the live sessions, links to the presentation videos, and details next steps.

The workshop connected the web platform and the professional media production communities and explored evolutions of the web platform to address professional media production requirements. 24 workshop talks were published in October 2021, about 40 issues were discussed online, and 3 live sessions were held mid-November 2021 that convened more than 75 experts to exchange on specific media production needs for the web platform.

The main outcomes are that:

  • The web platform already provides building blocks to enable core media production scenarios.
  • These building blocks are not powerful enough to create full-fledged experiences on client devices.
  • Most of the gaps raised during the workshop touch on API features in specifications that are already being developed. There is however benefit to VTG Oregon Ducks 1995 Rose Bowl T-Shirt Mens XL Green Football Distressed to make sure that media production needs are correctly captured and addressed in ongoing standardization activities.

Workshop discussions call for a more in-depth analysis of some of the topics, and workshop participants propose the creation of a Media Production Task Force that the Media & Entertainment Interest Group could host. The Task Force would be scoped to professional media production using the web platform, and responsible for documenting use cases and needs specific to professional media production, quantifying performance issues, promoting proposals to working groups and implementers, and tracking standardization progress and implementations. Workshop organizers are working with workshop participants and Media & Entertainment Interest Group chairs to facilitate the creation of the task force.

W3C thanks our sponsor, Adobe, the 5Pcs/Set APS-C CCD/CMOS Sensor Cleaning Swab Kit For DSLR Digital E0G4, workshop speakers, SMPTE, and all participants for making this event possible.

First Public Working Draft: Autoplay Policy Detection

15 March 2022 | Archive

The Media Working Group has published a First Public Working Draft of Autoplay Policy Detection. This specification provides web developers the ability to detect if automatically starting the playback of a media file is allowed in different situations.

The Working Group welcomes comments via the GitHub repository issues.

Last Call for Review of Proposed Corrections: WOFF File Format 2.0 Recommendation

10 March 2022 | Archive

The 2 Gray (EFP) Ear-hooks and Eargels for Motorola HX600 Boom Headsets has proposed corrections to the W3C Recommendation of WOFF File Format 2.0. Based on experience with WOFF 1.0, which is widely deployed, this specification was developed to provide improved compression and thus lower use of network bandwidth, while still allowing fast decompression even on mobile devices. This is achieved by combining a content-aware preprocessing step and improved entropy coding, compared to the Flate compression used in WOFF 1.0.

Comments, including implementation experience, are welcome via GitHub through 10 May 2022.

Working Group Note: MiniApp Widget Requirements

8 March 2022 | Archive

The MiniApps Working Group has just published a Group Note of MiniApp Widget Requirements. The MiniApp Widget is a special form of MiniApp Page. Unlike a page, a widget can occupy a certain area instead of the entire screen. It is used to display key information and respond to simple user operations, such as displaying the weather at the user’s current location, or tracking the user’s current travel status and providing further actions.

As the MiniApp Widget is an integral part of MiniApp, the other relevant parts are described in other related MiniApp documents. This document mainly describes the specific requirements that need to be considered when defining the MiniApp Widget Specification as well as other dependencies.

The Automotive Working Group has published the following two First Public Working Drafts:

  • VSSo Core: Vehicle Signal Specification Core Ontology: The core ontology introduces concepts for the structural elements of VSS defined through the rule set in the specifications. The core of the ontology defines this structure in an OWL ontology and serves as a basis for the defined signals of the standard catalogue and potential further development of the branches as more than structural information.
  • VSSo: Vehicle Signal Specification Ontology: As the core ontology defined the structure, VSSo holds the vocabulary as defined by the standard catalogue. The main objective is, that VSSo doesn’t diverege from the standard catalogue, so this is done automatically through tooling provided in the corresponding repository. The tooling takes the standard catalogue and maps it to concepts defined in the core ontology. The result is an OWL complient ontology, following the standard catalogue of VSS.

First Public Working Draft: MediaStreamTrack Insertable Media Processing using Streams

10 February 2022 | Cherokee Infinity Scrub Pants with the Bottom Drawstrings in Teal Size Xsmall

The Web Real-Time Communications Working Group has published a First Public Working Draft of MediaStreamTrack Insertable Media Processing using Streams. This JavaScript API allows to process raw video, either before it gets encoded or after it gets decoded, e.g. to add effects such as background blur to real-time video.

It builds on WebCodecs to expose the bytes that a video processing program needs to operate on. An earlier version of the API is available in Chromium, with demos that illustrate its usage.

W3C Web Fonts Working Group honored in 2021 Emmy® Awards

26 January 2022 | Archive

The National Academy of Arts and Sciences has released its 2021 list of Technology & Engineering Emmy® Awards today and we were delighted to discover that the 'Builder' Sliding Puzzle (PZ00015265), along with MPEG, will be honored for standardizing font technology for custom downloadable fonts and typography for web and TV devices.

This award represents the culmination of a quarter-century of work at W3C. Web Fonts enable people to use fonts on demand over the web without requiring installation in the operating system. W3C has experience in downloadable fonts through HTML, CSS2, and SVG. Downloadable fonts were not common on the web due to the lack of an interoperable font format. The Web Fonts effort addresses that through the creation of an industry-supported, open font format for the web called “WOFF” (Web Open Font Format) whose version 2, which became a standard in 2018, is deployed in all major web browsers and powers a vast majority of sites.

This is the third Emmy® Award in Technical & Engineering W3C has won. We will be working with our colleagues to send delegates to the ceremony that will be part of the National Association of Broadcasters (NAB) show in Las Vegas on April 25, 2022.

The Technology & Engineering Emmy® Awards are awarded to a living individual, a company, or a scientific or technical organization for developments and/or standardization involved in engineering technologies that either represent so extensive an improvement on existing methods or are so innovative in nature that they materially have affected television.
