Guangzhou Digital Media Group, a cable TV network operator, has selected 4Caster C4 encoder from Envivio, a provider of IP video convergence encoding services, to provide high definition and standard definition video encoding for interactive TV service based on the Microsoft Mediaroom platform.
Envivio said that 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.
Envivio also said that 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 Signes, 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.
