    Software reliability is closely influenced by the creation, manifestation and impact of software faults. Consequently, software reliability can be improved by treating software faults properly, using techniques of fault tolerance, fault removal, and fault prediction. Fault tolerance techniques achieve the design for reliability, fault removal techniques achieve the testing for reliability, and fau... View full abstract»

    Clusters of personal computers are becoming a viable, low-cost, alternative to traditional high-performance computing platforms as well as to more expensive networks of workstations. This is due in part to the better performance/cost ratio that characterizes personal computer hardware and in part to the outcome of various research projects aimed at producing high-speed communication systems out of...

    The paper deals with formal specification of the user interface layer for an audio-video conferencing tool. The used specification method is based on a combination of CADT (Concurrent Abstract Data Types) and DistTL (Distributed Temporal Logic). This combination allows to specify three views of an application: the architectural view, the view of the system and user behaviour and the view of data. ... View full abstract»

    Indexing video data is essential for providing content based access. This paper develops a data model and a rule-based query language for video content based indexing and retrieval. The data model is based on the notion of generalized strata, which can be seen as a set of intervals. Each interval can be analyzed to extract symbolic descriptions of interest that can be put into a database. This dat... View full abstract»

    The dynamic evolution of ecological systems in which predators and prey compete for survival has been investigated by applying suitable mathematical models. This kind of mathematical framework has been shown to be suited to describe evolution of economical systems as well, where instead of predators and prey there are consumers and resources. We believe that this kind of system, called dynamic sys... View full abstract»

    Providing VCR-like functions in distributed environments is not trivial, especially for multi-stream multimedia presentations, which may contain continuous media, e.g., audio and video, and static media, e.g., text and image. In this paper we: point out the main problems in interactive multimedia communications; propose some concepts to solve the problems; identify the control architecture for pro... View full abstract»

    The main function of a continuous media server is to concurrently stream data from storage to multiple clients over a network. The resulting streams will congest the host CPU bus, reducing access to the system's main memory, which degrades CPU performance. The purpose of this paper is to investigate ways of improving I/O subsystems of continuous media servers. Several improved I/O subsystem archit... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (586 KB)

    This paper is divided into two parts to reveal the interconnection between asynchronous transfer mode (ATM) and Ethernet, and to guarantee quality of service (QoS) for the multimedia data transmission. First, we have to solve the addressing problem. We discuss the addressing model for classical IP over ATM, LAN emulation, Peer model and Next Hop Resolution Protocol (NHRP). We then propose our addr... View full abstract»

    This paper presents a real-time entropy compression/decompression unit for disparity map information used in 3D teleconferencing systems. The disparity map data form a constant bit rate data stream which has to be transmitted through an ATM channel supporting lower data rates. The selection of the proper compression algorithm must be based on the durability of the regenerated data to various types... View full abstract»

    Multimedia services require high quality both of the signal and of the transmission systems. High performance must be achieved both in broadcasting services and in interactive ones, whose market is currently increasing throughout the world. There are several network architectures able to deliver high quality multimedia services: among these HFC systems are widely used. For example, in Italy SOCRAT... View full abstract»

    A proper initialization requires starting the process in a state close to the expected steady state. In Web caching, the initialization problem is faced each time a new document enters the cache. Independently of the method used to sort the documents into the cache, the newly referenced document is inserted in a so called "removal-list", from which documents are removed when storage space is neede...

  • Efficient memory management in VOD disk array servers using Per-Storage-Device buffering

    Publication Year: 1998, Page(s):551 - 558 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (704 KB)

    We present a buffering technique that reduces video-on-demand server memory requirements in more than one order of magnitude. This technique, Per-Storage-Device Buffering (PSDB), is based on the allocation of a fixed number of buffers per storage device, as opposed to existing solutions based on per-stream buffering allocation. The combination of this technique with disk array servers is studied i... View full abstract»

    We investigate the Sum Absolute Difference (SAD) operation, an operation frequently used by a number of algorithms for digital motion estimation. For such operation, we propose a single vector instruction that can be performed (in hardware) on an entire block of data in parallel. We investigate possible implementations for such an instruction. Assuming a machine cycle comparable to the cycle of a ... View full abstract»

    A diverse set of networking technologies have been trialed in developing transport solutions for tomorrow's multimedia services. Due to the various objectives, those services are foreseen to be carried over multiparty networks, based on different transport technologies. Therefore, smooth service supply requires that operators support multiple transport systems or at least offer interconnectivity b... View full abstract»

  • Retransmission scheme for MPEG streams in mission critical multimedia applications

    Publication Year: 1998, Page(s):574 - 580 vol.2
    Cited by:  Papers (2)  |  Patents (14)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (949 KB)

    Since multimedia data are characterized by continuity and massive volume, compression techniques such as MPEG are used for efficient transmission. However, transmission error occurring at a frame tends to be propagated to other frames because MPEG frames cross-reference one another upon presentation. Due to time constraints, it is usual to discard without retransmission the data which have transmi... View full abstract»

    To support large storage capacity and fulfill real time characteristics of continuous media storage systems, we need to improve the performance of disk I/O subsystems. To improve the performance, we exploit a data sharing scheme that reduces the number of disk I/Os. We utilize the advance knowledge of continuous media streams that is used to anticipate block demands, and so promoting the sharing o... View full abstract»

  • Designing interactive multimedia learning systems on the Web using a new graphical navigational design technique

    The traditional navigational design techniques do not provide a good way of handling the complexity of the navigational path of hypermedia systems, such as a learning system on the Web. When the number of pages (or nodes) of the learning system grows, the links among these pages increase exponentially. This makes the navigational design diagram of a twenty page, e.g., hypermedia learning system al... View full abstract»

    This paper discusses an experimental application which utilises sound (structured musical stimuli) to communicate aspects in the execution of a sorting algorithm. The musical properties investigated are the perception of variable rhythmic patterns (within a list of 13 elements communicated with a sequence of 13 notes in the Diatonic scale), the use of triads whose root position dependent on the lo...

    This paper suggests a new image compression scheme, using the discrete wavelet transformation (DWT), which is based on attempting to preserve the texturally important image characteristics. The main point of the proposed methodology lies on that, the image is divided into regions of textural significance employing textural descriptors as criteria and fuzzy clustering methodologies. These textural ... View full abstract»
