M&E IG Task Force

• Objective for M&E IG Task Force: to identify what new or changed standards are needed:
• A new data interchange format, e.g., TTML/ WebVTT?
• A new client/server API?
• Changes to HTML?
• Etc.
• Bring broader input and awareness from M&E IG members to help answer the above questions
• Further spec development will continue in the Bullet Chatting CG

Media production use cases

• Background and problem statement
• Plans for 2020

Media production use cases:�Background

Professional media assets, including audio-visual masters for television and motion pictures, are increasingly being stored in the cloud.

There is a corresponding growing interest in building web applications allowing end-users to manipulate these professional media assets. Such manipulation include, for example, quality checking, timeline editing, timed text authoring, etc.

While the web platform has evolved to support consumer media applications, e.g., video players, professional applications require additional capabilities, including precise timing, wider color gamut and high-dynamic range, higher-fidelity timed text, etc.

Media production use cases:�Problem statement

What limitations of the web platform prevent the development of professional media applications, and how should these limitations, if any, be addressed?

Media production use cases:�Plans for 2020

• Presentation at M&E IG F2F meeting at TPAC 2019 (minutes)
• M&E IG GitHub issue 4

Next:
