In high-reliability display environments (e.g., flight simulators, medical imaging, broadcast walls), the viewerframe — the logical frame presented to an observer — must be consistent in mode, timing, and authenticity. Three orthogonal properties govern this:
“Verified” means the viewerframe currently displayed matches the intended frame at mode and refresh parameters. Three verification layers: viewerframe mode refresh verified
It re-confirms that the user still has an active session, preventing the stream from timing out during long periods of inactivity. In high-reliability display environments (e
