Mbl4 Broadcast V1.12 Now

Perhaps the most requested feature: SDI-IP stream corruption healing. If the MBL4 detects a corrupt SDP (Session Description Protocol) file or a malformed RTP header, v1.12 will roll back to the last known good configuration stored in an encrypted flash partition. The rollback takes 1.8 seconds – down from 12 seconds in v1.11 – making it virtually unnoticeable during live talk shows.

The most striking gain is the 48 concurrent flows per 10G port. This allows a single MBL4 card to handle four independent UHD sources plus 44 ancillary data streams (closed captions, OP-47, timecode, etc.) without resorting to link aggregation. | Metric | MBL4 v1

Network hiccups shouldn’t mean black screens. v1.12 introduces ASR, which dynamically duplicates critical packets across multiple egress paths. If one route degrades, viewers see no glitch — just seamless continuity.

A European soccer league tested v1.12 to bond four 5G modems and one Starlink dish. The Predictive Path Redundancy automatically ranked the paths by jitter (Starlink 14ms, Vodafone 5G 22ms). When the Vodafone tower degraded at halftime, the MBL4 shifted the clean feed to Starlink within the vertical blanking interval – no freeze, no glitch.
