Chunghwa Telecom chooses Envivio to drive iPhone, 3GPP mobile TV service

SOUTH SAN FRANCISCO, USA: Envivio has announced that N-Type, a leading systems integrator in Taiwan, is deploying a multi-channel Envivio Mobile TV Headend that will enhance the capabilities of Taiwan's largest telecommunications company, Chunghwa Telecom (CHT).

The all-IP Envivio Mobile TV head-end featuring the 4Caster C4 Three Screens encoder/transcoder replaces CHT's existing software-based infrastructure, enabling CHT to support today's most exciting Android smartphones and the Apple iPhone. The headend will deliver both 3GPP and HTTP live streaming services. CHT presently serves over 9.4 million mobile subscribers, with more than half of those (4.9 million) receiving 3G services.

"The CHT team knows that when a subscriber chooses an advanced smartphone, they expect to take full advantage of their device's vibrant screen and performance capabilities," said Wilson Liu, General Manager, N-type.

"Envivio's Mobile TV Headend will enable CHT to deliver services that consistently provide an outstanding experience that is tailored to today's most desirable devices. We are also streamlining CHT's operations because Envivio multi-profile encoders simultaneously prepare content for all devices and delivery methods."

Envivio's Mobile TV Headend uses the 4Caster C4 to encode content in multiple profiles to enable full support for Apple's HTTP live streaming technology. This adaptive live streaming solution combined with Envivio's H.264 Extreme codec ensures the continuous delivery of video to iPhones, regardless of fluctuations in network bandwidth.

Envivio's 4Caster C4 simultaneously streams the same content for 3G devices, which can include iPhones and the latest generation Android smartphones. Advanced features such as network-aware rate control and video display aspect ratio management help to ensure the best quality of experience for customers.

"The mobile device landscape is constantly changing," said Envivio CEO Julien Signès. "The Envivio Mobile TV Headend gives service providers like CHT the flexibility and reliability needed so that they are fully prepared to support the demands of their subscribers with the best possible video experience, regardless of what new device or format may come along. The expertise of our partner, N-Type, is invaluable in helping CHT smoothly and quickly migrate its headend."

The Envivio 4Caster C4 encoding platform provides video compression for all Three Screens of consumer video – TVs, PCs and mobile devices – from a single platform. Designed to enable fixed line and mobile network operators to deliver content simultaneously across the full range of consumer devices, the 4Caster C4 is able to take multiple channels of content and encode them simultaneously to deliver multiple mobile TV profiles, multiple Internet TV profiles, or SD and HD IPTV profiles.
