Envivio Inc.’s Three Screens solution based on the 4Caster™ C4 encoding system has now been used to launch four new 3G-based Mobile TV implementations across China. These new multi-channel services, including deployments by China Unicom, Shanghai Mobile, Shanghai Telecom and Xin Huashe, offer live and video on demand TV options to millions of subscribers.
These latest deployments are built on the 4Caster C4 Three Screens encoder from Envivio, which supports high quality compression for H.264 and AVS, and an extensive array of network protocols including DTMB and CMMB. The flexible software design of the 4Caster C4 enables it to readily adapt to evolving standards and local requirement and as a result has been widely adopted in China where it supports delivery to all Three Screens.
Envivio 4Caster C4 provides mobile consumers with a smooth, first-rate viewing experience similar to what they expect from cable or satellite TV in the home. Using quality-enhancements such as Envivio Elite and Extreme codecs, 4Caster C4 optimizes video streams for each handset’s video resolution and aspect ratio, from budget 3G devices to the most advanced iPhone, Android, Windows Mobile and other smartphones. Advanced QoS with new adaptive bitrate streaming technologies ensures continuous viewing even under changing WiFi or 3G network conditions. The flexible Envivio software architecture enables the company to readily add support for new devices and ongoing quality enhancements.
