Paper Title: 

Wireless Multimedia – Challenges and Applications

Abstract: 

The adoption of the wireless Internet strictly depends on the mobile bandwidth. The new 3G technologies with speeds of 2 to 4 Mbps will open doors for many innovative wireless applications that use streaming video and multimedia. In this paper, we address several wireless multimedia challenges and present potential solutions. The capacity of a wireless video system is limited by the available bandwidth of the radio spectrum and various types of noise and interference. The wireless channel is the weakest link of multimedia networks, because mobility causes fading and error bursts. Therefore, we introduce in the paper a new scalable video coding scheme that can adapt in real time to the bandwidth variations over heterogeneous wireless networks. Another challenge deals with delivering rich digital media over wireless networks that have high error rates and low and varying transmission speeds. We introduce an innovative multimedia error control technique that provides error resilience and can recover from packet loss. In the second part of the paper, we present an overview of wireless multimedia applications including M-commerce applications, transaction management, digital content delivery, and telemetry services. We also discuss the future of wireless systems including 4G technology. Finally, we present a prototype of a commercial wireless phone system, for which we have designed and developed a real time video coding and transmission system.
