Stirlitz Media Logger
The best broadcast & IP compliance Logger for TV, OTT & Radio

Stirlitz Media Logger (SML) is a TV & radio after-broadcast/compliance logging solution that is different from other loggers - it is friendly for non-tech users and engineers alike. SML software runs on a standard Windows server (local or in the cloud). The Logger is ideal for capturing a single or a mix of multiple SD, HD, UHD and audio channels off MPEG-TS, OTT, NDI, SDI and AES67. It’s scalable, affordable, easy to use and most of all, rock solid.

SML WebPlayer showing multiple stations with ratings.

The unique Timeline based SML Player gives authorized users instant access to any part of the recordings. It is the most user-friendly Player on the market, suitable for non-tech users as well as engineers and producers. The webPlayer runs in modern web browsers on workstations and mobile devices (iOS & Android). Power users can opt for the Windows desktop Player.

Integrate SML with 3rd party software, by using the SML webPlayer API that allows you to add webPlayer elements to any browser based interface, or to call for exports from the recorded logs.
