Scientific-Atlanta has developed a supercharged version of its Digital Network Control System (DNCS) software.

The software will help cable ops give subscribers Video-on-Demand (VOD) and Subscription Video-on-Demand (SVOD) services on a large scale. Besides removing the headache of poor network capacity, they will be able to add value to services they offer. Expanded VOD/SVOD capacity will help consumers become more receptive to on-demand interactive TV services.

Scientific- Atlanta' s digital interactive network already delivers interactive TV applications to digital cable subscribers in North America. The company said that the operators who deploy Scientific-Atlanta powered networks have an end-to-end system which can consistently be upgraded. But the operators who don't have a scalable, digital interactive network system behind the set-tops they deploy cannot offer VOD and SVOD on a large scale.

Scientific-Atlanta's DNCS software takes care of the complex network traffic which is necessary for the smooth delivery of high bandwidth, interactive digital video and data services to subscribers. DNCS performs functions like set-top provisioning, session management, network flow control and optimising bandwidth. DNCS also coordinates communications between applications servers, set-tops, and other devices on the cable operator'sn etwork.

Time Warner Cable plans to upgrade some of its sites to Scientific-Atlanta's new network software, which will provide the reliable and scalable platform for their VOD and SVOD rollout. Scientific-Atlanta is also helping Comcast aggressively rollout VOD across two million homes by the end of the year.
