    Advances in high speed networking technologies and video compression techniques have made video-on-demand (VOD) services feasible. A large-scale VOD system imposes a large demand on bandwidth and storage resources, and therefore, parallel disks are typically used for providing VOD service. Although striping of movie data across a large number of disks can balance the utilization among these disks,... View full abstract»

    Video databases and video on demand represent an important application of the evolving global information infrastructure. However, video querying involves a lot of user interaction and feedback based query refinement, which can generate large traffic volumes on the network if full video segments are sent. To aid in efficient video browsing, search and retrieval across the network, we need to find ... View full abstract»

    In contrast to pure video servers, advanced applications such as digital libraries or teleteaching exhibit a mixed workload with massive access to conventional, “discrete” data such as text documents, images and indexes as well as requests for “continuous data”. In addition to the service quality guarantees for continuous data requests, quality-conscious applications requir... View full abstract»

    Multimedia systems are gaining importance as novel computer and communication system architectures, which are specialized to the storage and transfer of video documents. Consider a multimedia-on-demand server which transmits video documents through a high-speed network, to geographically distributed clients. The server accumulates requests for specific documents in separate queues. The queues need... View full abstract»

    The automatic organization of video databases according to the semantic content of data is a key aspect for efficient indexing and fast retrieval of audio-visual material. In order to generate indices that can be used to access a video database, a description of each video sequence is necessary. The identification of objects present in a frame and the track of their motion and interaction in space... View full abstract»

    Continuity of stream playback is the crucial constraint in designing a continuous media server. From a distributed memory architectural model developed earlier, we found that there were many points where the stream capacity of the server could be improved. The stream capacity was usually limited by the storage bottlenecks. Serving streams from memory cache eliminates disk accesses and data transfe... View full abstract»

    Multimedia presentations are stored into and queried from multimedia databases. In an earlier work, we have designed a graphical query language, called GVISUAL, that allows users to query multimedia presentations based on content information. In this paper, we discuss GVISUAL query processing techniques for multimedia presentations. More specifically, we discuss the translation of GVISUAL queries ... View full abstract»

    The Enhanced Pay-Per-View (EPPV) service model provides an effective way of delivering continuous media (CM) data clips to a large number of different clients. The aim is to share CM streams among various clients, thereby increasing the level of concurrency beyond the capacity limitations of available resources, while guaranteeing an upper bound on the clients' waiting time. In the EPPV service mo... View full abstract»

  • An image retrieval system for distributed environments

    Publication Year: 1998, Page(s):67 - 74
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (176 KB)

    We describe a prototype image retrieval system for distributed environments based on 2D projection interval relationships (2D-PIR). The system transforms an image to a symbolic representation that describes spatial relationships among objects in the image. The image database consists of three parts: the real image repository (which is distributed) and the symbolic and iconic image repositories (wh... View full abstract»

  • Query by rhythm: an approach for song retrieval in music databases

    We propose techniques for retrieving songs by rhythm from music databases. The rhythm of songs is modeled by rhythm strings. The song retrieval problem is then transformed to the string matching problem. In order to allow approximate string matching, we define similarity measures on rhythm strings. An index structure, called L-tree, is proposed to support efficient sub-string matching. Retrieval a... View full abstract»

    Conventional wisdom holds that reducing disk latency leads to higher disk utilization, maximizing disk utilization leads to higher throughput, and employing a faster disk leads to better performance. All of this is true when building a conventional file or database system. We show that these principles can be misleading when applied to a media server. To design such a server, we propose a cost-bas... View full abstract»

    The problem of the design and implementation of parallel metric tree indexes, called M-trees, is elaborated. Four different object declustering techniques are proposed and tested in order to get a sufficient evidence needed for specifying the pros and cons of their application. In general, the obtained I/O speedup and scaleup levels are high. A method for dealing with the CPU parallelism is also p... View full abstract»

    Techniques that emphasize software reuse and scalability are becoming more important than ever. We present a component-based model for continuous-media applications. Components encapsulate expert knowledge and facilitate reuse. They provide a toolkit that is used to create a wide range of continuous-media applications. Our model is scalable in several dimensions: media transformations, number of p... View full abstract»

    Cost cutting and personnel restructuring are forcing organizations to make difficult decisions on where to spend money. Among the areas hit hard by budget cuts are education and training. Academic, industrial, and governmental institutions are all seeking means to leverage technology to improve the timeliness, efficiency, and standardization of their required training. One way to extend budgets wh... View full abstract»

  • Object delivery in distributed continuous media servers

    Supporting uninterrupted delivery in distributed continuous media servers is not a trivial task. We propose an eager pipelining policy that allows distributed continuous media servers to utilize resources, that are otherwise unused, to support a display. We also propose a delivery technique that enables continuous media servers to deliver objects at multiple rates View full abstract»

    Based on a fifteen month investigation of post production facilities for both the entertainment and broadcast industries, we identified a number of challenges that arise when designing a server in support of multiple editing stations. These include how to: share the same content among multiple editors; support continuous display of the edited content for each editor; support complex editing operat... View full abstract»

    A key characteristic of video data is their associated spatial and temporal semantics. It is therefore important that a video model, does not only model the characteristics of objects but also their relationships in time and space. In view of this, the purpose of our work is to design a model for the specification of the spatio-temporal relationships among objects in video sequences. The model doe... View full abstract»

    This paper presents a method of automatically creating hypermedia documents from conventional transcriptions of television programs. Using parallel text alignment techniques, the temporal information derived from the closed caption signal is exploited to convert the transcription into a synchronized text stream. Given this text stream, we can create links between the transcription and the image an... View full abstract»
