Scientific-Atlanta's New Digital Content Manager Enables Next Generation Digital Video Networks

- DCM addresses new demands for digital simulcast and ad insertion, switched digital broadcast, more HD and on-demand digital channels -

ATLANTA, June 15 /PRNewswire-FirstCall/ -- Launching the next wave of advanced digital video services and continuing the march toward the all digital network is placing heavy video management and processing demands on service providers' networks. Operators are faced with a dramatic increase in both the number and complexity of MPEG video streams processed, while seeking to improve digital video picture quality in a highly competitive environment. To help meet these challenges, Scientific-Atlanta is announcing a new high- density networked MPEG processing platform, the Digital Content Manager (DCM), that will provide the versatility and processing power necessary to deliver digital simulcast, switched digital broadcast, more HD and on-demand digital channels, and expanded ad insertion opportunities.

The Scientific-Atlanta DCM will deploy game-changing technologies that will enable approximately 20x the MPEG processing capability of traditional multiplexing equipment currently in use. The ability to simultaneously process up to 2,000 standard definition (SD) or up to 500 high-definition (HD) MPEG video streams from a single platform will provide operators new flexibility in multiplexing architectures, as well as impressive scalability and cost-per- stream points not previously available.

"We are at an inflection point for digital networks that will require service providers to take their video processing capabilities to a new level supported by the Scientific-Atlanta DCM," said Dwight Duke, President, Transmission Network Systems at Scientific-Atlanta. "All this processing power is complemented by the DCM's next generation transrating algorithms, which enable the addition of an incremental digital program per QAM with no loss in digital video quality."

The capacity to handle up to 2,000 SD or up to 500 HD video streams simultaneously will also require a new approach to the user interface; another strength of the DCM platform. Using embedded HTML and JavaScript, the graphical user interface (GUI) will provide extensive drag and drop operations in a simple and intuitive layout for rapid access to all the functionality and processing power of the DCM.

The new Scientific-Atlanta DCM will enable service providers to:
* Launch digital simulcast, HDTV, on-demand and switched digital
applications -- with minimal impact to network bandwidth.
* Economically process the exploding number of complex SD and HD digital
video streams.
* Increase targeted local advertising avails, at a lower cost per stream
-- capable of handling up to 1,000 simultaneous ad insertions.
* Deliver an incremental digital program per QAM with no degradation in
video quality versus competitive solutions.
* Operate the system via a stand-alone HTML interface, or seamlessly
integrated with Scientific-Atlanta's ROSA(TM) network management system
* Support future applications, such as AVC transcoding/splicing and
conditional access.

The Scientific-Atlanta Digital Content Manager is currently scheduled for commercial availability in October 2005.
