Envivio, a provider of IP video convergence encoding solutions for telcos and broadcasters, reportedly announced that it’s “4Caster C4” video encoder has been selected by Guangzhou Digital Media Group.
According to Envivio, the 4Caster C4 is a three screens multi-channel multi-profile video encoder. It is a completely integrated solution for IPTV (News - Alert), Internet TV and mobile TV applications, and forms the part of company’s convergence generation IP video head-end that receives, decodes, re-encodes, as well as transmits programming - all in IP.
The 4Caster C4 supports digital, analog and MPEG-2 transport stream, over IP inputs. IN addition to supporting a wide range of video and audio encoding options, C4 also supports Chinese AVS (News - Alert) video compression standard, in order to ensure efficient delivery of content to the “Three Screens,” said the company.
Envivio (News - Alert) officials said that its MPEG-4 AVC compression offers at least twice as many high definition and standard definition channels when compared to MPEG-2. The conversion to an IP delivery mechanism offers content delivery flexibility as well as efficient support of the advanced interactive features of Microsoft (News - Alert) Mediaroom.
Guangzhou, a cable TV network operator in Guangzhou City, China, selected 4Caster C4 to facilitate both high-definition and standard definition video encoding – for China’s first Interactive TV service that is based on the Microsoft Mediaroom platform. Officials said that the installation is first Mediaroom-powered service that is delivered over a cable TV network.
Guangzhou Digital Media Group said that it’s new Zhujiang Digital connected TV service operates along with company’s existing analog and MPEG-2 digital services. It is delivered via IP across the same network.
Julien Signès, president and chief executive officer 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.”
Envivio claims that it’s the only company to offer convergence solutions supporting the “Three Screens” of consumer video – TVs, PCs and mobile phones – facilitating IP video over any type of network and to any multimedia device from mobile to HD.
