“…In addition, some research works are devoted to the modeling and retrieval of generic multimedia presentation, defined as a synchronized and possibly interactive delivery of multimedia as a combination of video, audio, graphics, still images, and animations [16]. In this sense, a Flash movie is a typical type of multimedia presentation.…”

As a prevailing web media format, nowadays Flash™ movies are created, delivered, and viewed by over millions of users in their daily experiences with the Internet. However, issues regarding the indexing and retrieval of Flash movies are unfortunately overlooked by the research community, which severely restrict the utilization of the extremely valuable Flash resource. A close examination reveals that the intrinsic complexity of a Flash movie, including its heterogeneous media components, its dynamic nature, and user interactivity, makes content-based Flash retrieval a host of research issues not thoroughly addressed by the existing techniques. As the first endeavor in this area, we propose a generic framework termed as FLAME (FLash Access and Management Environment) embodying a 3-layer structure that addresses the representation, indexing, and retrieval of Flash movies by mining and understanding of the movie content. An experimental prototype for Flash retrieval is implemented to verify the feasibility and effectiveness of FLAME, and future research directions on Flash management and retrieval are discussed in details.

Abstract. Quality of Service (QoS) is defined as a set of perceivable attributes expressed in a user-friendly language with parameters that may be objective or subjective. Objective parameters are those related to a particular service and are measurable and verifiable. Subjective parameters are those based on the opinions of the end-users. We believe that quality of service should become an integral part of multimedia database systems and users should be able to query by requiring a quality of service from the system. The specification and enforcement of QoS presents an interesting challenge in multimedia systems development. A deal of effort has been done on QoS specification and control at the system and the network levels, but less work has been done at the application/user level. In this paper, we propose a language, in the style of constraint database languages, for formal specification of QoS constraints. The satisfaction by the system of the user quality requirements can be viewed as a constraint satisfaction problem, and the negotiation can be viewed as constraint optimization. We believe this paper represents a first step towards the development of a database framework for quality of service management in video databases. The contribution of this paper lies in providing a logical framework for specifying and enforcing quality of service in video databases. To our knowledge, this work is the first from a database perspective on quality of service management.
