The latest advances in wireless data access technologies and increased popularity of mobile computing have enabled the development of the future mobile Internet. The various wireless technologies and standards already developed or under development support the existence of a highly heterogeneous wireless communication environment in which mobile users access the network from diverse devices and exchange data of various types. In the context of such a heterogeneous wireless and mobile environment, maintaining certain level of Quality of Service required by some applications and consequently providing high user Quality of Experience is very challenging. This chapter analyzes the state of the art in quality-oriented mobility management in heterogeneous wireless environments in the context of mobile multimedia applications. Most important wireless access technologies and multimedia support systems and protocols for wireless delivery are presented, while requirements for quality-oriented mobility management are identified. Handover management is discussed as the component of the mobility management system with the greatest impact on the quality as measured by the user. Finally a novel multimedia mobility management framework is presented which aims at maintaining high user perceived quality while efficiently exploiting all the communication resources available in a heterogeneous wireless environment.

“…General principles and different approaches for MDC are reviewed in [5]. Approaches for generating multiple descriptions include data partitioning (e.g., even/odd sample or DCT coefficient splitting) [5], multiple description (MD) quantization (e.g.,MD scalar or vector quantization) [6], and multiple description transform coding (e.g., pairwise correlating transform). Another MD encoding approach is based on combinations of video segments (codeblocks, frames, orgroup of pictures) encoded at high and low rates.…”

“…This means that the content needs to be delivered in different formats simultaneously to different users according to their capabilities and limitations. In order to handle such obscurity, scalability emerged in the field of video coding in the form of Scalable Video Coding (SVC) [1][2][3][4] and Multiple Description Coding (MDC) [5][6]. Both SVC and MDC offers an efficient encoding for applications where content needs to be transmitted to many non-homogeneous clients with different decoding and display capabilities.…”

Abstract. High quality multimedia contents can distribute in a flexible, efficient and personalized way through dynamic and heterogeneous environments in Future Internet. Scalable Video Coding (SVC) and Multiple Description Coding (MDC) fulfill these objective thorough P2P distribution techniques. This chapter discusses the SVC and MDC techniques along with the real experience of the authors of SVC/MDC over P2P networks and emphasizes their pertinence in Future Media Internet initiatives in order to decipher potential challenges.Keywords: Scalable video coding, multiple description coding, P2P distribution. IntroductionFuture Media Internet will entail to distribute and dispense high quality multimedia contents in an efficient, supple and personalized way through dynamic and heterogeneous environments. Multimedia content over internet are becoming a well-liked application due to users' growing demand of multimedia content and extraordinary growth of network technologies. A broad assortment of such applications can be found in these days, e.g. as video streaming, video conferencing, surveillance, broadcast, e-learning and storage. In particular for video streaming, over the Internet are becoming popular due to the widespread deployment of broadband access. In customary video streaming techniques the client-server model and the usage of Content Distribution Networks (CDN) along with IP multicast were the most desirable solutions to support media streaming over internet. However, the conventional client/server architecture severely limits the number of simultaneous users for bandwidth intensive video streaming, due to a bandwidth bottleneck at the server side from which all users request the content. In contrast, Peer-to-Peer (P2P) media streaming protocols, motivated by the great success of file sharing applications, have attracted a lot of interest in academic and industrial environments. With respect to conventional approaches, a major advantage in using P2P is that each peer involved in a content delivery contributes with its own resources to the streaming session. However, to provide high quality of service, the video coding/transmission technology needs to be able to cope with varying bandwidth capacities inherent to P2P systems and end-user characteristics
