- The site says only playback notes and position pass between windows—not the film’s picture or sound.
Field notes
The page walks through two separate Chrome windows joined by a link; play, pause, seek position, and episode number are described as the signals passed between them, not the stream itself. Its headphone demo includes English and Russian samples, and says Chrome briefly uses microphone permission to identify headphone names before switching it off. Netflix is listed as working; HBO Max and the other named services are still being tested or queued.
