    In a distributed multimedia system, multimedia sessions may get involved with multiple media servers for the retrieval of the media data or the creation of new multimedia documents. To provide the guaranteed Quality of Service (QoS) to real-time applications such as continuous media transfers, the system resources in the media servers must be reserved to avoid contention during execution time.

  • Reducing variation in bit-rate produced by encoder in MPEG video

    Publication Year: 1999, Page(s):6 - 10 vol.2
    Cited by:  Papers (4)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (569 KB)

    A shortcoming of current video transmission using the MPEG standard is that its encoder produces a variable bit rate (VBR). Due to this, the encoder output has to be buffered and released over the network at a constant rate. This buffering of the encoder output introduces an additional delay between the encoding and decoding phases of the video transmission. To remedy this problem, we present a st... View full abstract»

  • An abstract layered model for hypermedia document system

    Publication Year: 1999, Page(s):11 - 15 vol.2
    Cited by:  Papers (1)

    We propose a layered model for hypermedia document systems and use this model in the design and implementation of a prototype hypermedia document system. The model consists of three layers: a runtime layer (RTL) a document description layer (DOCDL) and a storage layer (SRL). The DOCDL contributes to defining the logical structure. It not only constrains the structure of the SRL, but also forms a b... View full abstract»

  • On satisfying timing and resource constraints in distributed multimedia systems

    Publication Year: 1999, Page(s):16 - 20 vol.2
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (504 KB)

    We present a new synchronization strategy for multimedia applications executed in a distributed environment. This strategy makes the timing properties of the system and the quality of the media presentations predictable since one is able to determine analytically whether the timing requirements of each multimedia application will be met, and if not, which timing requirements will fail. The propose... View full abstract»

  • Multi-phase interval caching for a news on demand server

    Publication Year: 1999, Page(s):21 - 25 vol.2
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (575 KB)

    We propose a buffer cache algorithm to build a cost effective storage server for real time news objects. In a news on demand server the number of concurrent streams is bounded for the maximum disk bandwidth the NOD server provides. The maximum numbers of concurrent streams can be increased more than the total disk bandwidth supports if the buffer cache is applied to hold hot news objects. However ... View full abstract»

    We present an implementation of Web based multicast audio and video application over QoS enabled networks. In order to apply QoS guaranteed multicast audio and video to the Web, architecture extension for real-time stream transmission, session directory service and QoS delivery embedded into the Web is needed. We attempt to identify a solution that can be deployed immediately. We design and implem... View full abstract»

  • Optimal bandwidth-buffer trade-off for VBR media transmission over multiple relay-servers

    Publication Year: 1999, Page(s):31 - 35 vol.2
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (600 KB)

    Given a client buffer the minimum bandwidth required to transmit a pre-recorded VBR media can be computed in O(n) (n is the frame number). As n is usually very large, this resource management procedure is not suitable for online computation. We have proposed an O(nlogn) algorithm to characterize the bandwidth-buffer tradeoff for the optimal resource management. However, it cannot be applied to a g... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (584 KB)

    Distributed multimedia document systems and distributed video servers are examples of multimedia presentations involving collaboration among multiple information sources. In such applications, objects have to be retrieved from their sources and presented to users according to specified temporal relationships. Object retrieval in these collaborative applications is influenced by the presentation ti... View full abstract»

  • Multi-rate variable-quality VOP shape coder

    Publication Year: 1999, Page(s):46 - 50 vol.2
    Cited by:  Papers (1)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (329 KB)

    Many MPEG-4 shape coding algorithms have been formulated to provide the user with no specific control over the rate or quality of compression. These algorithms are either optimised for high quality or low bit rate. Thus a high quality optimised algorithm will be inefficient in a low bit rate application and vice versa. Hence, to achieve a highly efficient coding algorithm, a novel multi-rate varia... View full abstract»

    The deployment of metadata on the World Wide Web is probably one of the most important steps in its evolution. Its widespread use will foster applications such as efficient information retrieval and filtering, trust management and support for agents. Following this trend, the Structured Graph Format (SGF) supports the description of Web site structures in a machine understandable way. We describe ... View full abstract»

    This paper presents a color image zerotree coding algorithm with a significantly reduced memory requirement, thus making it hardware implementation friendly. The memory reduction was achieved by using the lifted wavelet transform and listless zerotree coding (LZC). The lifted wavelet transform has a lower memory requirement and lower implementation complexity than the traditional filter bank imple... View full abstract»

    We propose a best-effort video delivery scheme that can be deployed on networks in use today, including Ethernet LANs or the Internet. This scheme detects congestion by measuring the buffer occupancy and loss rate and estimates available channel bandwidth by measuring the incoming data rate at the client receiver. The frame request rate is adjusted accordingly when congestion is detected. No extra... View full abstract»

    Synthetic environments provide new possibilities for learning and training. Added benefits can be achieved by the use of networks. This requires the distribution of applications and their interoperability. In the case of distributed simulation, a new standard called High-Level-Architecture (HLA) exists. HLA was defined by the DMSO/DOD of the United States of America. Together with its partners in ... View full abstract»

    We introduce a new concept of a server-based architecture for continuous media streams, e.g., audio and video. This server architecture provides highly flexible, scalable media streaming for Internet applications. One of its key features is the client driven stream encoding and stream composition process. The client applies server side applets that control the encoding components for the various s... View full abstract»

    We have observed the failure of RSVP to be widely accepted as the solution to resource reservation in the Internet. Because we are convinced of the need for resource reservation, in at least parts of the Internet, to support multimedia communications, we have set about trying to improve RSVP. By careful study of the protocol, we have identified areas for improvement, and propose REDO RSVP, a reduc... View full abstract»

    Due to the success of new multimedia technologies, there is a great interest in providing a resource allocation strategy suitable for multimedia applications. Many solutions proposed in the literature are based on proportional share resource allocation, such as WFQ, WF/sup 2/Q, EEVDF or SFQ. In a previous paper we showed how to perform resource reservation according to a constant bandwidth allocat... View full abstract»

    Modern multimedia applications require new services from communication systems. Quality of Service (QoS) is one of the core issues in multimedia systems. QoS is established through negotiation between users and service providers. The negotiation typically involves allocation and management of resources in order to attain a desired level of quality. Unfortunately, in present day systems, the networ... View full abstract»
