Envivio announces that its 4Caster C4 Three Screens multi-channel, multi-profile encoder for IPTV, Internet TV and Mobile TV applications has been qualified by the Microsoft Mediaroom Interoperability and Qualification Lab for SD video encoding. The thorough testing 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.

Designed as an integrated solution for IPTV, Internet TV and Mobile TV applications, the 4Caster C4 supports digital, analog and MPEG-2 Transport Stream over IP inputs, and a range of video and audio encoding options to support efficient delivery of content to the Three Screens. The 4Caster C4 supports a wide range of encoding formats including the Chinese AVS video compression standard.

The 4Caster C4 can support one channel of high definition or multiple channels of standard definition encoding for IPTV. It also offers optional support for Picture in Picture, Internet TV encoding up to VGA resolution and multi-profile encoding for mobile TV streaming. For IPTV applications, 4Caster C4 can be delivered in either Premium Compression or Extreme Compression encoding configurations using Envivio's new flexible encoding core. For Internet TV applications, 4Caster C4 can deliver content for playback in Windows Media Player, QuickTime and VLC. For Mobile TV applications, 4Caster C4 can deliver 3GPP, 3GPP2 compliant streams for playback on a wide variety of mobile devices

Envivio's unique high-availability hardware platform combined with an embedded software encoding core offers levels of service flexibility and encoding performance upgradeability not possible with traditional hardware-only compression platforms. Encoding performance can be upgraded with each software release with no need to buy and install new hardware. New services and features can be added in the same way.
