Abstract
Ambient Intelligence aims to provide the means to transparently adapt the environment to the user needs. This paper focuses on the aspect of transmitting images over heterogeneous, unreliable networks to a diversity of terminals. The transparent adaptability to the heterogeneous environment is obtained through scalability concepts, providing support to the “Encode Once, Decode Everywhere” paradigm. The scalability is implemented using the intrinsic properties of the wavelet based coding, and data protection is based on turbo codes. Optimized hardware implementations of both technologies are described and intelligently exploited to provide support to the aforementioned Ambient Intelligence goals. All proposed solutions devote special attention to compliance with standards: MPEG-4 for compression, MPEG-21 for scalability and adaptation approaches and UMTS/IEEE 802.11 for error protection.
