Envivio's 4Caster C4 Three Screens multi-channel, multi-profile encoder  has been qualified by the Microsoft Mediaroom Interoperability and Qualification Lab (IQ Lab) for SD video encoding.

The testing programme performed by the IQ Lab is designed to ensure long-term interoperability and compliance of encoders and other critical components intended to support deployments of the Microsoft Mediaroom IPTV platform.

"Our Interoperability and Qualification Lab was designed to give the world's leading IPTV service providers the best choice of carrier-grade encoding platforms that are fully compatible with Microsoft Mediaroom," explained Dan McCrary, director of the global partner ecosystem for Microsoft Mediaroom.

"The commitment of key vendors like Envivio to this important quality assurance process is fundamental to the proven excellence of Mediaroom-powered services and their continued success with consumers."
