EMERGING types of wireless applications and mobile computing services, which are rich in multimedia content with high demands for network resources and strict quality of experience (QoE) requirements, put more and more pressure for further research on efficient multimedia services provision over cellular systems, raising the need for novel applications development and delivery management techniques, as well as creating new challenges in standardization activities, in terms of multimedia quality evaluation. The incredible evolution of multimedia-capable mobile devices (e.g., smart phones, net- books, and tablets), as well as modern advances in telecom- munication networks and multimedia technologies, has led to a number of research efforts dedicated to adopt advanced multimedia techniques, including content processing/analysis, scalability issues, and cross-layer (CL) optimization methods for audiovisual services support. A large number of con- tent providers support delivery of services, which are rich in multimedia content, through sophisticated wireless network platforms. Such services include real-time digital audiovisual content, as well as streaming and teleconference applications hosting high-definition video and audio of increased quality. In addition, several wireless network platforms support the provision of user-centric applications, allowing mobile users to create, manipulate, and deliver their own multimedia content, using handheld devices.
