Betreff: Call for Consensus (CFC): APA Comment on Picture in Picture

Colleagues: This is a Call for Consensus (CfC) to the Accessible Platform Architectures (APA) Working Group testing for agreement on an updated formal comment to the Picture in Picture specification. (

The document was authored by the Media Working Group ( .

An accessibility review was requested of the APA as part of our role in performing horizontal review of W3C documents for accessibility concerns.

It was reviewed by APA member Becky who proposed that an accessibility statement be included with this specification. The goal is to provide implementers of picture in picture with accessibility guidance. The following proposed accessibility  considerations statement was discussed at the July 28, 2021 APA meeting (

It is important that the interface for picture in picture meets the requirements of the Web Content Accessibility Guidelines (WCAG). All users must be able to find and navigate to/from the picture in picture and enable/disable/operate all controls using various input modalities, color and contrast settings, and assistive technologies.

For example, the WCAG Guideline 2.1 requires, "Make all functionality available from a keyboard". Any picture in picture implementation and interface must be full operational with the keyboard only.

If the group agrees, this comment will be posted to the Media Working Group's picture-in-picture github issues tracker (

***Action to Take***

This CfC is now open for objection, comment, as well as statements of support via email. Silence will be interpreted as support, though messages of support are certainly welcome.

If you object to this proposed action, or have comments concerning this proposal, please respond by replying on list to this message no later than 23:59 (Midnight) Boston Time, Wednesday 4 August.

NOTE: This Call for Consensus is being conducted in accordance with the APA Decision Policy published at:
