All the parts that compose the application, such as sound, video, text and buttons are described in this model and the browsing semantics are also specified. The MORENA model provides support for dynamic data, such as video or audio. It also provides structured authoring, fine-grained synchronization of media, flexibility and adaptability through message passing, user interaction, easy prototyping and simulation, and the ability to reuse logical specifications. MORENA's parent is Trellis, but it was influenced by many other systems, merging their features in a coherent and consistent framework. Applications written based on the MORENA model are compact and platform independent.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129533881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypermedia represents one major segment in this market. Though the advances in multimedia technology have enabled us to create dazzling displays of hypermedia instructional material, its instructional efficacy is somewhat unclear. In part this is due to the often simplistic cause and effect models used to evaluate hypermedia applications. Such simplistic models tend to obscure outcomes. Moreover, they ignore the theories that would explain when and how hypermedia instruction might be efficacious. To this effect, the authors offer a research methodology which incorporates an evaluation model. The model, heavily based in hypermedia learning theories, is used to examine the efficacy of a hypermedia system called KARTT, the Knowledge Acquisition Research Training and Teaching Tool.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129602259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to fulfil these requirements, we use a parallel image server architecture which relies on arrays of intelligent disk nodes, each disk node being composed of one processor and one or more disks. This contribution analyzes through simulation the real-time behavior of two multiprocessor multi-disk architectures: GigaView and the Unix workstation cluster. GigaView incorporates point-to-point communication between processing units and the workstation cluster supports communication through a shared bus-and-memory architecture. For a standard multimedia server architecture consisting of 8 disks and 4 disk-node processors, we evaluate stream frame access times under various parameters such as load factors, frame size, stream throughput and synchronicity requirements. We compare the behavior of GigaView and the workstation cluster in terms of delay and delay jitter.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124574828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jung","doi":"10.1109/MMCS.1995.484912","DOIUrl":"https://doi.org/10.1109/MMCS.1995.484912","url":null,"abstract":"In multimedia retrieval applications such as architectural design, interior design, and real estate marketing, there exists a generic class of user queries that require retrieving images in the database that are spatially similar to the user query. We propose an image representation scheme (referred to as 3D spatial orientation graph or simply SOG) and an algorithm (referred to as SIM/sub 3D/) for retrieving 3D images of relevance (based on spatial similarity) to user queries from large image collections. Spatial similarity between a query and a database image is quantified based on the number as well as the extent to which the edges of SOG of the database image conform to the corresponding edges in the SOG of the query image. The time complexity of SIM/sub 3D/ is /spl Theta/(|E/sub q/|+|E/sub d/|) where |E/sub q/| and |E/sub d/| are the number of edges in the query and database images. SIM/sub 3D/ is robust in the sense that it can recognize translation and scale variants of apt image and these properties are shown formally. The effectiveness of SIM/sub 3D/ is evaluated using a testbed image collection. The testbed comprises 60 images and are produced by generating 3 variants of each of the 15 original images. Image variants are produced by translation and scale transformations, and an arbitrary composition of these two transformations. The variants are designed to examine the robustness of the proposed algorithm. The results produced by the algorithm on a set of test queries are in agreement with the intuitively expected results.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121021626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The user can create and modify the private knowledge of a tele-action object, so that the tele-action object will automatically react to certain events to pre-perform operations for generating timely response, improving operational efficiency and maintaining consistency. Moreover tele-action objects also possess a hypergraph structure leading to the effective presentation and efficient communication of multimedia information. The active multimedia system (AMS) is provided to manipulate and maintain the TAOs. The user interface and the system architecture for the AMS are described. A multimedia mail system is implemented to illustrate the usefulness of tele-action objects. Finally, we discuss the advantages of the proposed approach and future research.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122505543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With fixed rotation speed, however, transfer rate varies with track location, as does the number of video streams that can be played concurrently. This paper proposes Track Pairing, a deterministic scheme for static intra-disk data layout. By recording each movie alternately on \"outer\" tracks and their \"inner\" counterparts, a disk's throughput becomes independent of the viewers' choices and its guaranteed streaming capacity is maximized. With a 1.8:1 ratio of outermost to innermost track capacities, guaranteed streaming capacity is increased by 40 percent, and is merely 22 percent below the streaming capacity of the outermost track! Temporal overhead is modest, and required buffer sizes are smaller than those with the Logical Track scheme, which also maximizes guaranteed throughout. Track-Pairing has been implemented under Microsoft's Windows NT, and can be extended to multiple disk drives.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133828182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
