ATLANTA, Dec. 21 /PRNewswire-FirstCall/ -- From digital video recording (DVR) to IPTV to high-definition TV (HDTV) and Voice over IP (VoIP), consumers are presented with more and more choices in an ever-evolving digital world. At the 2006 International CES, Scientific-Atlanta will demonstrate its pioneering role in designing and developing dynamic and powerful consumer products for consumers that promote ease of use, expanded content options, enhanced navigation and innovative personal applications that further entertainment mobility. Visitors to the booth will see how Scientific-Atlanta is helping consumers 'live simply' with multi-purpose devices that do more for you and take up less room in your living space. The company will also offer 'a peek behind the curtain' at what is next in concept for whole-home entertainment, future interactive television applications and on-demand content services.

Booth Demonstrations include: Consumers: Ways to Download and Watch Content on Your Terms: - DVR with built-in DVD Recorder/Player -- No more changing inputs on your TV and juggling remotes. Scientific-Atlanta's DVR with built-in DVD recorder and DVD player, is three powerful devices in one -- a high-powered digital set-top box, a DVR and a DVD recorder/player -- with only one remote to operate. The DVD recorder/player is powered by Sonic Solutions' AuthorScript(TM) DVD engine, the same DVD creation technology used by Hollywood. The first and only networked set-top of its kind, the DVR with DVD Recorder/Player enables the creation of personal DVDs from DVR content libraries, and the ability to take recorded shows and watch them on the go. Scientific-Atlanta's DVR with built-in DVD Recorder/Player has received the Consumer Electronics Association's "Best of Innovations" award for Video Components in the CES Innovations 2006 Awards competition. - Voice, Data and Wireless -- Named an "Innovations 2006 Design and Engineering Honoree" by the CEA, Scientific-Atlanta's DCP2223(TM) Voice over IP cable modem with DECT (Digitally Enhanced Cordless Telephony) enables the consumer to use cordless handsets in the home to access VoIP service. Scientific-Atlanta will also be showing its wireless gateway, wireless caller ID functionality, and a full line of voice, data and wireless products. Service Providers: Ways to Simplify Launch of Services - IPTV Solutions -- Whether your networks are DSL, FTTx or HFC, you will want to see how the combination of our latest IPTV set-tops in development and a robust switched video network can deliver new and exciting entertainment services to consumers. Enhanced navigation experiences, next-generation digital video recording and expanded personal applications are just a sample of the new enriched IPTV services on the horizon. - OCAP -- With an eye on the future and support of interoperability of OpenCable(TM) Application Platform (OCAP(TM)) applications across cable networks, Scientific-Atlanta is committed to the development of next- generation platforms. Our solutions are designed to provide new revenue-generating opportunities for operators as they expand their services, while simplifying the launch of services. A Visionary Leap:

While booth demonstrations of these products are futuristic concepts, and the products are not currently in production, Scientific-Atlanta is exploring these innovative technologies to complement consumer trends.

- DVR to Phone Applications -- Provide the access and control your consumers are looking for, using their mobile phone. At CES, Scientific-Atlanta and Sprint will demonstrate applications that enable subscribers to check what's on television tonight from their mobile phone; program their DVR from their mobile phone; stream broadcast television to their mobile phone; stream previously recorded programs from their DVR to their mobile phone; and even track the location of their child's mobile phone on the television. - High-Definition Multi-Room(TM) DVR -- With Scientific-Atlanta's High-Definition Multi-Room DVR, you can one day view, control and share recorded DVR content in both standard-definition and high-definition programming. A concept demonstration will show how simple it is to use, explain the benefits of having all content stored in one place, enable consumers to see how to access stored content from multiple rooms, and highlight the convenience of everyone watching what they want, when they want, where they want - with true clarity. - Media Center -- A concept demonstration that streams MP3 audio, digital photos, games and home movies stored on a PC to a television using a Media Center set-top. Using your advanced digital services, video, music, pictures and games truly converge, providing subscribers with all they need, in one network. - DVR Direct to Disc -- Scientific-Atlanta will showcase a business model demonstrating a feature of our DVR with built-in DVD Recorder/Player that includes the ability for service providers to one day offer downloads of content on-demand, including movies and music, giving consumers the power to purchase content and directly burn copies of DVDs and/or CDs using their set-top box. - Residential Gateway -- A demonstration of Scientific-Atlanta's prototype xDSL modem with integrated HPNA3 IP Over Coax technology highlights the ability to reuse existing cabling in the home to easily connect next generation IPTV devices. *NOTE TO EDITORS
