I disagree with this proposal. While the "resizing" requirement is in "simple video communication service" as "The users can change the display sizes during the session", I believe the basic use case does not derive the requirement that the change in video size be communicated to the other party. I would propose the following changes: - Reinstate the text below: 4.2.4. Video Size Change 4.2.4.1. Description Alice and Bob are in a video call in their browsers and have negotiate a high resolution video. Bob decides to change the size of the windows his browser is displaying video to a small size. Bob's browser regenerates the video codec paramters with Alice's browser to change the resolution of the video Alice sends to match the smaller size. 4.2.4.2. Derived Requirements F22 ( It SHOULD be possible to modify video codec parameters during a session.) - Change the text of F22 to be: It SHOULD be possible for one party to request a change in video codec parameters, such as size, during a session, and for the other party to react to this request.
