Cable Operator Guangzhou Digital Media Group Uses Envivio Convergence Headend for New Interactive TV Service


Envivio 4Caster C4 Three Screens Encoder Delivers HD and SD Content on World’s First Microsoft Mediaroom Cable TV Deployment

South San Francisco, CA . – Envivio Inc., the leading provider of compression solutions for Three Screens video convergence, today announced that its 4Caster C4 has been selected by Guangzhou Digital Media Group to provide the high definition and standard definition video encoding for China’s first Interactive TV service based on the Microsoft Mediaroom platform. The installation is also the world’s first Mediaroom-powered service delivered over a cable TV network.

Guangzhou Digital Media Group’s new Zhujiang Digital connected TV service operates alongside the company’s existing analog and MPEG-2 digital services and is delivered via IP across the same network. The MPEG-4 AVC compression provided by Envivio allows at least twice as many SD and HD channels to be delivered to consumers when compared to MPEG-2. Converting to an IP delivery mechanism provides content delivery flexibility and efficient support of the advanced interactive features of Microsoft Mediaroom.

Julien Signès, President and CEO of Envivio said, “Guangzhou has built a remarkably compelling system which combines Envivio advanced encoding with Microsoft Mediaroom interactivity and time-shifting to unlock the full potential of IP-based television for its customers, without having to make major changes to its existing transport infrastructure. They have set an example not only in China, but for cable TV operators all around the world.”

The 4Caster C4 encoder has been qualified by the Microsoft Mediaroom Interoperability and Qualification Lab (IQ Lab). A fully 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, including the Chinese AVS video compression standard, to ensure efficient delivery of content to the Three Screens.
