Mediaproxy announced new features for its Monwall multi-viewer platform, including instant replay for live incident review and the ability to monitor HTML content directly within mosaic outputs.

The instant replay tool allows operators to use a web interface or physical control surface to rewind mosaic outputs for immediate incident analysis without disrupting live monitoring. The feature supports multiple mosaics and frame-level playback for detailed review, which the company says is especially valuable during critical broadcasts that require rapid on-air issue resolution.

The update also introduces HTML content monitoring, enabling operators to add picture-in-picture HTML windows to any mosaic output or the interactive multiviewer client. This allows broadcasters to monitor web dashboards — such as those displaying analytics, metrics or live status updates — alongside traditional broadcast feeds.

Mediaproxy said the HTML feature supports both static and dynamic content, including streaming platforms such as YouTube, Hulu, Roku and Fubo, giving operators a unified view of broadcast and web-based sources in a single interface.
