A Set-Top Box With Virtual Platform Support for QoS Management in IMS Based Multiple Provider Networks

Free registration required

Executive Summary

Set-Top Box (STB) has evolved from being a device just sitting on top of a TV shelf to a device providing a gateway to the Internet for a home network, receiving services from multiple content providers, and enabling and ensuring Quality of Service (QoS) for the streaming media. IP Multimedia Subsystem (IMS), with its promise to provide a converged access network for multimedia service delivery (such as Triple play & Quadruple play services), has to guarantee QoS support. To enable QoS in IMS-based networks, the authors have designed a set-top box which provides feedback to the service provider to ensure end-to-end QoS. Their set-top box is designed to provide virtual platforms such that it can support multiple service providers.
