The service that this connection provides is also authorized to lose a number of objects. The POC approach establishes a conceptual link between both connectionless best-effort (CL) and connection oriented (OC) protocols. This approach is motivated by the fact that heterogeneous CL networks such as the Internet are plagued by unordered delivery of packets and losses, which tar the performances of current protocols. Moreover, it has been showed, in several research works, that out of order delivery is able to alleviate the use of network resources such as memory and bandwidth, and reduces end-re-end transit delay. But, in order to take advantage of these benefits, applications must be able to relax some transport constraints. A temporal extension of POC, called TPOC (for Temporal POC), is introduced. TPOC offer a conceptual framework, which allow the QoS of distributed multimedia applications to be fully taken into account. The architecture for offering a TPOC transport service is introduced and evaluated for the transport of MPEG video streams. The authors demonstrate that POC connections fill not only the conceptual gap between CL protocols (such as UDP) and OC protocols (such as TCP) but also provides real performances improvements for the transport of multimedia streams such as MPEG video.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

The basic model for Web interaction is that a client requests a page of data which can include images and hyperlinks within it. This interaction model is inadequate for real-time multimedia (MM) applications, since the Web and its associated set of protocols, e.g. HTTP, do not support the real-time transfer of the continuous media (Audio/Video). Several solutions have been proposed to support real-time playout of continuous media via the Web, e.g. Netscape. Most of these solutions do not provide means to the user to negotiate the desired presentation quality (in terms of quality of service (QoS) parameters settings); even the proposals that provide QoS negotiation (more generally QoS management) are used in a rather static manner, that is, the video/audio servers are a priori known. The authors propose to integrate in the WWW a dynamic QoS management approach that allows (1) the user to negotiate the desired QoS; and (2) and to select the \"best\" video/audio server which might support the user requirements. This activity is based on the general structure of multimedia documents and associated QoS parameters, called meta-data, which they developed under an ongoing CITR project. The main objective of the paper is to integrate meta-data associated with MM document in WWW e.g. Netscape; this will allow one to use dynamic QoS management protocols.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.

This fact has severe consequences for the efficient indexing and retrieval of information from documents in large unstructured collections (e.g. WWW), because it is very difficult to automatically identify generic meanings from visual or audible objects. A novel method for image retrieval from large collections is proposed in this paper. The method is based on color co-occurrence descriptors that utilize compact representations of essential information of the visual image content. The set of descriptor elements represents \"elementary\" color segments, their borders, and their mutual spatial distribution on the image frame. Such representation is flexible enough to describe image scenes ranging from simple combinations of color segments to high frequency color textures equally well. At the retrieval stage the comparison between a given query descriptor and the database descriptors is performed by a similarity measure. Image descriptors are robust versus affine transformations and several other image distortions. The consideration of the descriptors as sets of elements allows the combination of several images or subimages into a single query. Basic properties of the method are demonstrated experimentally on an image database containing 20000 images.","PeriodicalId":305422,"journal":{"name":"Proceedings 1998 MultiMedia Modeling.
