In conventional network processing models, a number of data-copies are needed for applications to receive data from network interfaces. This causes major overhead and becomes a serious limitation in distributed multimedia applications. Therefore, several mechanisms have been proposed for reducing the number of data-copies. We emphasize that the Single Virtual address Space (SVS) OS introduces a new buffering mechanisms for this purpose. In this paper, we describe our SVS OS, which we call "Cubix (CUBe of 2-byte unIX)", with a new Access Control List protection mechanism and a new buffering mechanism, which we call "Cstreams (Continuous streams)", based on it. We emphasize that our proposed Cstreams realizes a single data-copy network architecture. ©2004 Copyright SPIE - The International Society for Optical Engineering.

The Communications Resource Manager (CRM) provides communications at a specified Quality of Service (QoS) for networked multimedia workstations in an environment where the network and workstation resources are changing. The CRM enables a consistent application interface and manages all workstation communications resources. It established network connections on behalf of applications, monitors their progress and notifies applications when network QoS events take place. Applications can then modify their behavior (compression rate, number of simultaneous media, media type) to cope with the change. The CRM provides mechanisms to negotiate at call setup time the level of multimedia support provided. If optimal resources are not available, call quality degradation paths allow call establishment at the highest QoS possible. Call admission based on on-going network performance monitoring and application performance feedback from the CRM can be used to prevent further QoS degradation by refusing to attempt connections when insufficient resources are available. The CRM enables existing multimedia workstations to communicate in an environment with known QoS. The CRM flows naturally into emerging QoS techniques for end-to-end ATM services. Because the CRM operates at the application level it is also applicable to the ATM interconnection of LANs whereas current ATM Forum proposals are not.

There is now a huge variety of multimedia applications, network technologies and end-system architectures. Within this new and challenging environment, the importance of Quality of Service (QoS) mechanisms to allocate and monitor system resources has been recognized. A key goal of our research is how to manage the QoS requirements of heterogeneous receivers in applications that depend on multipeer communications. This paper presents results of our recent work on QoS filter mechanisms that operate on compressed video and audio streams. These filter mechanisms adapt the QoS of continuous media streams allowing diverse qualities of media to be delivered to a number of receivers in the same multipeer dissemination tree. The paper focuses particularly on filter operations applied to bandwidth-demanding video services in order to allow low capability clients, primarily connected via mobile and other low-bandwidth links, to participate in these dissemination services. This is performed without detriment to existing high capability clients. The results presented show the feasibility of providing individual QoS to individual clients.

The recent advances in multimedia systems, together with the advent of high speed networks, paved the way to a new generation of applications. In particular, the authoring environments have found in multimedia the means of increasing the richness of information contained in electronic documents. With the evolution of new computer systems that can handle multimedia information, time-based data can be integrated in electronic documents taking into account their temporal dimension. In such documents, temporal dependencies between the different media objects define a temporal structure within the document. This structure is the basic support for the representation of dependencies between data such as audio, video and virtual images. Furthermore, it allows the scheduling of presentation actions during the document presentation. The presentation of multimedia documents is dynamic and the positioning of objects in time together with their duration have to be specified. To achieve this operation efficiently, a high level temporal representation is needed which allows the author to specify all the temporal dependencies between multimedia objects. In this paper, we propose an interval-based temporal model and constraints which provide a basis for the management of the consistency of multimedia documents. We propose an efficient algorithm allowing the detection of a wide range of inconsistencies. The emphasis in the design of these algorithms is put on the handling of both the flexibility of temporal specifications and the indeterministic behaviour of some media objects. Furthermore, we use the logical organization of the document in nested entities to enhance the performance of the methods used for detecting inconsistencies. The aim of our approach is to fulfill the following requirements . Structured modelling: The document content is defined by a hierarchy of nested components where leaves are basic media objects and nodes composite objects. . Incremental manipulation of th

The preservation of QoS for multimedia traffic through a data network is a difficult problem. We focus our attention on video frame rate and study its influence on speech perception. When sound and picture are discrepant (e.g., acoustic `ba' combined with visual `ga'), subjects perceive a different sound (such as `da'). This phenomenon is known as the McGurk effect. In this paper, the influence of degraded video frame rate on speech perception was studied. It was shown that when frame rate decreases, correct hearing is improved for discrepant stimuli and is degraded for congruent (voice and picture are the same) stimuli. Furthermore, we studied the case where lip closure was always captured by the synchronization of sampling time and lip position. In this case, frame rate has little effect on mishearing for congruent stimuli. For discrepant stimuli, mishearing is decreased with degraded frame rate. These results indicate that stiff motion of lips resulting from low frame rate cannot give enough labial information for speech perception. In addition, the effect of delaying the picture to correct for low frame rate was studied. The results, however, were not as definitive as expected because of compound effects related to the synchronization of sound and picture.

It has been recognized that an effective support for multimedia applications must provide Quality of Service (QoS) guarantees. Current methods propose to provide such QoS guarantees through coordinated network resource reservations. In our approach, we extend this idea providing system-wide QoS guarantees that consider the data manipulation and transformations needed in the intermediate and end sites of the network. Given a user's QoS requirements, multisegment virtual channels are established with the necessary communication and computation resources reserved for the timely, synchronized, and reliable delivery of the different datatypes. Such data originate in several distributed data repositories, are transformed at intermediate service stations into suitable formats for transportation and presentation, and are delivered to a viewing unit. In this paper, we first review NETWORLD, an architecture that provides such QoS guarantees and an interface for the specification and negotiation of user-level QoS requirements. Our user interface supports both expert and non- expert modes. We then describe how to map user-level QoS requirements into low-level system parameters, leading into a contract between the application and the network. The mapping considers various characteristics of the architectures (such as the hardware and software available at each source, destination, or intermediate site) as well as cost constraints. ©2004 Copyright SPIE - The International Society for Optical Engineering.

We propose a multiple-delivery transport service tailored for graphics and video transported over connections with wireless access. This service operates at the interface between the transport and application layers, balancing the subjective delay and image quality objectives of the application with the low reliability and limited bandwidth of the wireless link. While techniques like forward-error correction, interleaving and retransmission improve reliability over wireless links, they also increase latency substantially when bandwidth is limited. Certain forms of interactive multimedia datatypes can benefit from an initial delivery of a corrupt packet to lower the perceptual latency, as long as reliable delivery occurs eventually. Multiple delivery of successively refined versions of the received packet, terminating when a sufficiently reliable version arrives, exploits the redundancy inherently required to improve reliability without a traffic penalty. Modifications to acknowledgment-repeat-request (ARQ) methods to implement this transport service are proposed, which we term `leaky ARQ'. For the specific case of pixel-coded window-based text/graphics, we describe additional functions needed to more effectively support urgent delivery and asymptotic reliability. X server emulation suggests that users will accept a multi-second delay between a (possibly corrupt) packet and the ultimate reliably-delivered version. The relaxed delay for reliable delivery can be exploited for traffic capacity improvement using scheduling of retransmissions.

CD-ROMs have proliferated as a distribution media for desktop machines for a large variety of multimedia applications (targeted for a single-user environment) like encyclopedias, magazines and games. With CD-ROM capacities up to 3 GB being available in the near future, they will form an integral part of Video on Demand (VoD) servers to store full-length movies and multimedia. In the first section of this paper we look at issues related to the single- user desktop environment. Since these multimedia applications are highly interactive in nature, we take a pragmatic approach, and have made a detailed study of the multimedia application behavior in terms of the I/O request patterns generated to the CD-ROM subsystem by tracing these patterns. We discuss prefetch buffer design and seek time characteristics in the context of the analysis of these traces. We also propose an adaptive main-memory hosted cache that receives caching hints from the application to reduce the latency when the user moves from one node of the hyper graph to another. In the second section we look at the use of CD-ROM in a VoD server and discuss the problem of scheduling multiple request streams and buffer management in this scenario. We adapt the C-SCAN (Circular SCAN) algorithm to suit the CD-ROM drive characteristics and prove that it is optimal in terms of buffer size management. We provide computationally inexpensive relations by which this algorithm can be implemented. We then propose an admission control algorithm which admits new request streams without disrupting the continuity of playback of the previous request streams. The algorithm also supports operations such as fast forward and replay. Finally, we discuss the problem of optimal placement of MPEG streams on CD-ROMs in the third section.

For real-time communication services to achieve widespread usage, it is important that the network services behave gracefully when any component fails. In this paper, we describe techniques and mechanisms for maintaining network services for multi-party real-time communication in the face of failures that may make parts of the network inaccessible. These protocols provide high performance during normal operations and the network performance degrades gracefully in face of network failures; e.g. in the presence of failures, the routes selected may not be optimal, the connection set-up may take a little more time, or resource allocation may be less efficient. With these mechanisms, the real-time communication protocols achieve robustness to single and/or multiple failures in the network, without diluting the strength of the performance guarantees offered or sacrificing the system performance in the common case.

Placement of multimedia blocks on zoned disks

We examine the impact on optimal data placement schemes for random retrieval due to a new trend in disk technology, namely zoned magnetic disks, which record data with a constant linear density and have a constant angular velocity. This modifies the optimal data placement that minimizes response time, since now the data transfer time varies with block placement whereas the transfer time and cylinder capacity was constant for traditional magnetic disks. We focus on the optimal placement of video objects stored in multimedia servers that consist of fixed-size blocks of constant-bit-rate encoded data or varying-size blocks of variable-bit-rate encoded data. The differences in popularity and access rates among these objects allow minimization of seek times by varying the data placement. We describe an optimal placement of fixed-size blocks on zoned disks that minimizes response time. Video objects are accessed by streams that playout the blocks at a given rate, requiring disk access by a deadline in order to avoid glitches in playout. For the placement of varying-size blocks on zoned disks, we study a scheme that minimizes the probability that a block access misses its deadline. This is done by adjusting the value representing the popularity of blocks to take into account both block size and the relative importance of seek time and transfer time using a weighting factor. We quantify the improvements in disk throughput for a given block-deadline miss probability.
