Abstract

Currently, three incompatible proprietary solutions驴offered by RealNetworks, Microsoft, and Apple驴dominate the Internet streaming software market. In the near future, third-generation mobile communication systems will extend the scope of today's Internet streaming solutions by introducing standardized streaming services that target the mobile user's specific needs.3G systems will provide high-quality streamed Internet content to the rapidly growing mobile market. These systems will offer value-added applications as well, supported by an underlying network that combines streaming services with a range of unique mobile-specific services.Mobile-application scenarios present many challenges, such as how to provide spectrum-efficient streaming services over varied radio-access networks to different types of end-user terminals. The authors assert that their standards-based Interactive Media platform驴recently tested in several field trials驴addresses these challenges by using an architecture that fits seamlessly into 3G mobile-communication systems. An integral part of this architecture is a streaming proxy, which acts on both the service and transport levels.
