|top| | Viewerframe Mode Refresh Top

It looks like you're working with IP camera URL parameters, specifically the viewerframe mode used by certain network cameras (like Panasonic or Axis) to display live video streams in a browser.

Using mode=refresh forces the camera to send a Motion JPEG (MJPEG) stream. viewerframe mode refresh top

Scenario C: Video Streaming Synchronization

Problem: In a multi-viewer setup (e.g., security cameras), one stream falls behind the others. The "top" stream (the primary focus) is out of sync. It looks like you're working with IP camera

Implementation Patterns

• Simple scroll reset:

  Use Case 2: Video Playlist (The "TV Mode")

  In a video player with a playlist sidebar, "viewerframe mode refresh top" is ideal. When a live event ends and a new VOD is loaded: Simple scroll reset: Use Case 2: Video Playlist

  // 5. Change mode back to 'view' state.mode = 'view'; document.getElementById('modeIndicator').innerText = 'Mode: View';

  Mode=Refresh: A parameter that tells the camera to serve a series of static JPEG images that refresh at a set interval, rather than a continuous Motion-JPEG (MJPEG) stream. This was historically useful for browsers that couldn't handle MJPEG or for users on low-bandwidth connections.
