Once synonymous with synchronization, this broader interpretation is analogous to the performance of a symphony orchestra, which in itself is more than just a set of musicians playing at the same time; rather, it is a well choreographed collection of instruments played together according to a set arrangement. Orchestrating a multimedia presentation involves specifying its content, spatial and temporal structure, coordinating data retrieval, decoding and synchronization, as well as displaying the decoded media to the user. It is this coordinated management which constitutes the orchestration process. The problem is therefore to define an architecture that addresses each stage this life-cycle so that the semantics of the presentation and each of its component media are preserved. Such an architecture must be open to examination and modification at different points in order to provide a self-regulating system that evaluates and adapts its behaviour throughout the presentation. Consequently, an object-oriented approach to both implementation and performance management enables a system to dynamically respond to changing needs and environmental conditions in both a well-mannered and well-instrumented fashion.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"25 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":"122245201","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 addition, with the bit rate variation inherited from MPEG encoding scheme, this problem becomes more severe. Because of the variation over the video delivery path and the degree of aggressiveness in an admission decision, the possibility of a system over-loading situation is highly likely. How this affects the service quality (especially jitter behavior) under different disk scheduling schemes used in VOD servers is not well known. The authors intend to answer this question by conducting a simulation study of four basic disk scheduling schemes (First Come First Serve, SCAN, Circular SCAN and Earliest Deadline First). The result shows that each disk scheduling scheme demonstrates different behavior regarding to the number of supportable jitter free streams, the number of jitter incidents, the number of streams affected by jitter incidents, the jitter frequency, and the jitter delay time. The implication for the admission control strategy is discussed.","PeriodicalId":302885,"journal":{"name":"Proceedings of IEEE International Conference on Multimedia Computing and Systems","volume":"79 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":"124793409","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 spite of the fact that the throughput of a public network (e.g. ATM) can be huge, the network-I/O bottleneck limits the number of client stations a media server can support simultaneously. A possible solution to this problem is to batch requests for the same video and multicast the data to these requesters to save the network I/O bandwidth. A disadvantage of this scheme is that it unfairly forces requests arriving early in a batch to wait for the latecomers. As a result, the reneging rate can be high in a system which employs this technique. To reduce the long access latency, we examine in this paper a new batching mechanism called chaining. This approach allows the server to serve a \"chain\" of client stations using a single data stream. The idea is to pipeline the data stream through the chain of stations. Requests arriving early in a chain (virtual batch), therefore, do not have to experience long delays as in conventional batching. Our simulation results based on an ATM networking environment indicate that very significant performance improvement over batching can be obtained.","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":"125880663","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}
