Microsoft has opened a "Mediaroom" Interoperability and Qualification Lab (IQ Lab) 
at its campus in Mountain View, California to help enable the ongoing interoperability and compliance of encoders used in deployments of its IPTV software platform. IQ Lab-compliant encoding vendors will become recommended Microsoft Mediaroom ecosystem partners.
The new IQ Lab gives encoding vendors the opportunity to test their products in a controlled IPTV production environment, with set-top boxes from several vendors.

- In June 2007, Microsoft rebranded its IPTV software platform as "Microsoft Mediaroom", and added several new multimedia capabilities, including in-home personal music and photo sharing, dynamic MultiView (multiple picture-in-picture) capabilities, Multimedia Application Environment for development of interactive services and advanced applications, and digital terrestrial television (DTT) support.
