Advanced IPTV HeadendMeet Your IPTV Challenges with Outstanding

MPEG4-10 (H.264) Encoding Quality

The IPTV Challenge

If IPTV is part of your triple play plans, you know howimportant it is to implement a powerful, flexible, head-end solution. Your solution must be able to transmit thegreatest number of channels and best image quality withthe greatest possible bandwidth efficiency. DSL-basedsystems generally require superior MPEG4-10 (H.264)compression support, while solutions for HFC and FTTx

• Build the right headend system for your business, whether your networks are DSL, FTTx and/or HFC,whether you need a complete modular IPTV headend or individual open standards-based componentsthat will integrate with third party middleware and other systems.

• Deliver more content and better quality images over less bandwidth with best-in-class MPEG4-10(H.264) encoding, MPEG-2 encoding and IntelliRate™ transrating.

• Ensure greater flexibility and cost-effectiveness with dense signal reception and descrambling module, as well as intelligent,Gigabit Ethernet IP streaming.

• Maintain optimized performance with the ROSA™ monitoring and management system and easy integration to third party middleware systems.

networks can use powerful MPEG-2 technology due tothe higher bandwidths available. The right IPTV headendproducts must work together as a complete solution – oras part of an integration project with third party middle-ware and other systems. Additionally, dynamic monitoringand management is critical to assure continuous performance.

Scientific-Atlanta's IPTV headend solution haseverything necessary to deliver:

High Encoding Quality and Bandwidth Efficiency

Scientific-Atlanta is an expert when it comes to help squeezing capacity and

capability out of band-width. Our IPTV headend solution takes advantage

of second generation MPEG4-10 encoding that helps deliver excellent video

quality at lower bit rates, enabling operators to offer more channels per

home and to extend their TV offering to more remote subscribers. The

highly programmable hardware platform with extensive processing power

allows for continuous improvements in encoding quality.

Leading MPEG-2 transrating and encoding performance are also supported

for legacy systems or where sufficient bandwidth is available. Either way,

video quality is assured with additional compression improvement tech-

nology like Scientific-Atlanta's PreSightPlus™ adaptive pre-filtering and

look-ahead technologies and IntelliSight™ transrating technology, which

dynamically maintains optimized video quality with limited bandwidth.

A Complete Yet Modular Solution

Scientific-Atlanta's IP Video headend solution includes everything from

acquisition (signal reception from satellite, off-air, cable or other networks)

to descrambling, transrating, MPEG2 and MPEG4-10 (and optional VC1)

encoding and re-encoding, processing, encryption and IP streaming.

Dynamic Management and Monitoring

The ROSA™ system is a dedicated management platform for equipment

from Scientific-Atlanta and other vendors. Advanced features help ensure

the optimised system availability and help reduce operational expenses

(e.g., truck rolls and maintenance staff). The flexibility to easily integrate

equipment from almost any vendor ensures freedom of choice. ROSA

also offers the ability to track and prove performance and availability

for operators that must provide Service Level Agreement's.

The Proven Expertise of Scientific-Atlanta

Scientific-Atlanta has decades of experience designing advanced, high

quality digital headends for Cable, Satellite Broadcast and Telco Operators.

Ongoing, aggressive R&D combined with sales and service offices around

the world provide the people and infrastructure necessary to support

your IPTV efforts now and for years to come.
