The world’s appetite for video is growing. People are
watching more TV, from more sources, on an increasing
variety of screens. There is a huge opportunity to capture
more of a viewer’s time—if one overcomes the cost and
complexity of delivering to multiple screens.
The Envivio 4Caster™ C4 convergence encoding/ transcoding
platform provides the answer.
4Caster C4 delivers live and on-demand services for Mobile, PC and SD/HDTV screens, all
from a single platform, eliminating the need for separate headends for each. The product
of years of hands-on experience, 4Caster C4 is delivering services to millions of subscribers
worldwide. From bandwidth-limited mobile delivery to full HD over high-speed networks,
for one type of screen or many, 4Caster C4 enables your video headend to meet today’s
goals and provides fl exibility to address future opportunities.

EXTEND YOUR REACHOne Device to Support All Subscribers
Each screen and network has its own requirements that must be met to deliver the best service. With its multi-profi le encoding, 4Caster C4 serves multiple networks and many different consumer devices—both the ones they have today and those they will crave tomorrow. This enables a single head-end to deliver the best television experience for many consumer devices including:
• Mobile phones and mobile broadcast receivers
• PC and Mac
• Digital Set-Top-Boxes
The Best Video Delivery for Every Network
Ensuring a good quality of experience on heterogeneous network is a complex task because every network has unique characteristics and limitations. Broadcast networks have fi xed bandwidth constraints. 3G networks must maximize every bit of their limited bandwidth. The open Internet has no inherent Quality of Service mechanism. Envivio has developed technologies to optimally address the caveats of each network:
• Statistical rate control for broadcast distribution
• Network aware rate control for 3G
With 4Caster C4, live video can even be distributed on networks with no QoS thanks to bandwidth adaptation technologies such as:
• Microsoft Silverlight Smooth Streaming
• Adobe Dynamic Streaming
• Apple iPhone Adaptive Streaming
• 3GPP Bitrate Switching Streaming (BSS)
Output to the World
Broad support for standards and seamless interoperability with leading systems vendors cut through geographic and technical boundaries.
• For Mobile: DVB-H, DVB-SH, CMMB, ATSC Mobile DTV, 3GPP, 3GP2, HTTP streaming
• For PC: Windows Media, Silverlight, Flash Media, ISMA
• For TV: DVB, ATSC, ISDB-T, AVS
LOOK YOUR BESTQuality Comes First
Input video sources often arrive degraded and improperly formatted. Before encoding begins, advanced pre-processing prepares the source to appear and sound its best, by applying:
• Spatial de-noising fi lters for HD content
• Advanced de-interlacing for PC display
• Brightness and contrast adjustments
• Adjustable resolutions to match display capabilities
• Dynamic and manual aspect ratio management (letterboxing, cropping, etc.)
• Dynamic sound level compression and adjustment
The Right Tools for the Job
Different networks, services and devices have different requirements. So, for example, Envivio supports all the latest standard audio video codecs and related transport protocols: H.264 Baseline, Main and High Profi le, MPEG-4 Simple Profi le, AVS, VC-1 as well as AAC, HE-AAC and WMA. Furthermore, Envivio has developed refi ned codecs that further improve the quality of experience:
• Extreme compression: market-leading video quality for high-end mobile devices and the best quality TV experience
• Elite compression: for optimal playback on mid-range mobile devices with limited decoding capacity
• Premium compression: for high-quality, high-density IPTV at the lowest bit rates
Protect High Value Content
Integrated content encoding and encryption safeguard high-value content from the head-end to the consumer device. Supported technologies include:
• Ismacrypt, Simulcrypt for DVB-H
• CMMB encryption for CMMB
• Windows Media DRM for PC
• Microsoft Silverlight DRM, powered by PlayReady, for PC

DEPLOY WITH CONFIDENCE A Perfect Fit
Built for IP networks, the 4Caster C4 provides a high-quality,
all-digital signal fl ow that fi ts new and existing environments,
while simplifying operations, reducing equipment requirements
and cutting expansion costs. In addition to direct ingest of
MPEG-2 or H264 video over IP, 4Caster C4 supports a variety of
broadcast interfaces including analog, SDI, HD-SDI inputs, and
ASI output. Interfaces comply with specifi c regional needs to
smoothly fi t into broadcast architectures.
Absolute Reliability
A great subscriber experience begins with a service that is
on air, all the time. The high-availability platform is built with
server-grade components to deliver 99.999% uptime and
unshakeable performance. Features include:
• Redundant Ethernet ports for all I/O and control interfaces
• Dual, hot-swappable power supplies
• 4Manager automatic redundancy protection
Long Term Thinking
We not only make use of the latest Intel processor
capabilities—Envivio algorithms are built into Intel’s designs.
The fl exible software architecture makes it the only encoder
that can be enhanced throughout its life. A simple software
license enables the 4Caster C4 to be reconfi gured at any time,
