Update to the Call for Prior Art — Second Screen Working Group PAG

The Second Screen Working Group Patent Advisory Group (PAG), launched in August 2021 in response to disclosures related to a specification of the Second Screen Working Group, has issued an Update to the Call for Prior Art to seek prior art that is available in the public domain or on terms consistent with W3C's Royalty-Free Licensing Requirements. The update contains questions about prior art related to digital audio, digital imaging, and multimedia networking technology from the mid-2000s.

Feedback should be directed to group-secondscreen-prior-art@w3.org by 31 March 2022. For more information about the Second Screen Working Group PAG, see its home page and charter.
