Cable operators have already deployed this architecture, developed through collaboration between industry leaders and Scientific Atlanta. This open architecture is based on IP Multicast protocols and open interfaces to the QAM, SDV server, SDV manager and the Client. Benefits of an open platform include scalability, manageability and cost effectiveness, plus QAM sharing. The company’s SDV solution offers specific value-added features, including intelligent bandwidth management, session resiliency and server redundancy.

Imagine’s SDV system comprises the SDV staging processor and the QOD gateway. The SDV staging processor provides much better video quality than current clamping devices, according to the company. With the optional addition of the QOD gateway, 15 SDV signals can be statistically multiplexed within a 256-QAM channel with digital broadcast quality. Both products incorporate Imagine’s software on carrier-grade, off-the-shelf hardware, plug seamlessly into existing SDV infrastructure, and are compatible with centralized bulk encryption.

The company offers a turnkey solution that can be integrated with existing infrastructure to provide cable operators with the flexibility to offer additional channels that only consume bandwidth when they are actually being watched. Motorola also provides professional services to help support SDV deployments and help cable operators implement best practices for deploying and managing SDV. F aced with the need to carve out more bandwidth for HDTV, faster high-speed data services, video-on-demand, and other advanced services, cable operators are turning to a variety of tools to make the most of their existing capacity. One of the tools for packing more into the existing spectrum is switched digital video (SDV), which gives operators the power to dole out video content as subscribers request it. Because less-frequently-viewed video channels are transmitted only when subscribers ask for them, and not broadcast to all subscribers all of the time, SDV offers the promise of a virtually unlimited channel lineup. As an added benefit, it is often cited as one of the least expensive ways to expand bandwidth. SDV also allows operators to offer more niche content, without committing dedicated bandwidth to each special interest channel. As a reference, here’s a sampling of SDV architectures.
