The authors investigate a technique for managing the bandwidth of such a hierarchical storage design. In existing schemes, all data items are treated equally; and the same I/O rate is used to load data from tertiary storage when they are requested. In their approach, different loading rates are used for data items with different characteristics. For frequently used items, one keeps a large percentage of data in the disk buffer and needs to use only a small I/O rate to load the missing portions on demand. On the contrary, a larger portion of less frequently used items is kept in the tertiary storage. To minimize their access latencies, larger I/O rates are used to load the missing parts when these items are needed. They formally prove that this approach is better than using the same loading rate for all data items. They also show simulation results to quantitatively demonstrate the benefits of the technique. They confirm that the scheme is able to provide higher system throughput while ensuring very short latencies (i.e., several seconds) for essentially all accesses. Such good performance is achieved using surprisingly small disk space (i.e., about 5% or less of the database size).","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114573273","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}

To be effective across a wide range of activities, however, collaborative multimedia systems must support the integration of presentational, conversational and interactive multimedia within a single shared media space. Such a virtual environment must not only support synthetic and real-time media but also their interactive manipulation as shared objects. Therefore, synchronizing media and the actions upon them in both a timely and causal manner are necessary to maintain a semantically coherent workspace. This paper discusses these issues and introduces a framework based on Virtual Enablers and Virtual Barriers designed to support the diverse range of synchronization requirements within collaborative multimedia systems. Its associated architecture is described and the model's application to the field of telelearning is illustrated.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121557563","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 dual model consists of a document type hierarchy and a folder organization. Document type hierarchy is used to specify document types based on the analysis of layout, conceptual and content structures, and users define their own folder organization, which is used to store frame instances and the high level conceptual information of documents. A storage architecture is presented to integrate the document type hierarchy, the folder organization and the original document storage as a three level storage system, which in turn supports effective document searches. Document retrieval can be conceptual-based or content-based. Users are allowed to specify criteria for governing the document filing. An agent-based architecture for implementing the folder organization and the basic operations for constructing and reorganizing a folder organization are proposed.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115636192","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}

Closed-loop video rendering has significant advantages over open-loop schemes including reduced storage requirements which in turn reduces memory disk swapping time that constitutes a large portion of the time spent in the desktop editing of massive video material. Processing in the compressed domain also offers faster processing speeds due to the smaller data size present in the compressed domain. This approach also improves image quality since multiple decompression and compression processes are avoided during the editing process. Based on MPEG, a standard video compression scheme, the authors discuss fundamental techniques, analyze pros and cons, implications and preferences for a compressed domain video rendering system. A software-based system for real-time video rendering is proposed with preliminary results demonstrating the feasibility of their closed-loop MPEG video rendering approach.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129703316","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 original image is represented by several coefficients, one of them with visual similarity to the original image, but at a lower resolution.

Disk simulation and experiments with real disks are used to evaluate the performance of these strategies. The results indicate that significant performance improvements can be achieved with as few as four disks by placing image coefficients based upon browsing access patterns.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124155129","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}

Methods for measuring motion complexity and activity levels in the scene are presented, based on which a video scene can be consistently categorised into identifiable classes. Further, the video quality, as measured by the mean square error or the signal to noise ratio is related to certain parameters used in video analysis. Adaptability in the analysis is realised by tailoring the parameters of the video analysis algorithm to the specific characteristics of the video scene, as embodied in the video scene class and the video quality. Preliminary experiments show the feasibility of the proposal, and the improved performance that can be achieved by adaptively tuning the analysis parameters to the characteristics of the particular scene under consideration.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128451991","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}

Users can select the desired replaying time from several different levels, depending on how much time can be afforded for viewing.
