In the era of cloud, many media intensive applications will be executed on the cloud. In many application domains, new methods/paradigms are necessary for the scenario of cloud environment. In addition, most of today`s cloud technologies are developed for generic applications. Thus, they often have to trade efficiency for generality. Unfortunately, because multimedia applications are often involved with sheer volume of data and tremendous amount of computation, such inefficiency could lead to unacceptable service latency. Thus, the objective of this project is (1) to propose new methods/paradigms for multimedia applications under the cloud environment and (2) to propose new framework designs for multimedia-aware clouds to provide reliable and efficient multimedia services. This project aims to explore possibilities along this direction for several important multimedia applications. In particular, we will study (1) highly parallel video coding, (2) privacy preserving media search, and (3) 3D rendering clouds. For each of these applications, we will implement it on the cloud, analyze its characteristics and propose necessary design changes for its application on clouds if necessary. The research topics involve both hardware architecture (such as hybrid clouds with heterogeneous processors and configurations of computing nodes) and software framework (such as coding methods, privacy-preserving indexing, novel programming paradigms, load balance algorithms, etc.). We believe the developed technologies will help the industry respond to the paradigm shift and leverage the great opportunities in multimedia-aware cloud applications.雲端系統安全演算法社群網路multimedia cloudprivacy preserving media searchsocial network
