Negotiation of QoS is a balancing process between the QoS specified by a client, the resource availabilities of the distributed system and the functional capabilities of the distributed application. Negotiation requires application level QoS descriptions and an end to end view spanning the whole distributed application. NRP is an application level protocol meeting these requirements. NRP performs negotiation based on client specified QoS value ranges and given resource availability on endsystems and communication links. NRP is independent of application level QoS semantics. It allows QoS negotiation and resource reservation in three phases and supports a wide range of distributed application topologies.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128841327","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}

It is shown that the performance of the GA-based motion estimation algorithms nearly approaches that of the full search algorithm (FSA). However, the computational complexity of the existing GA-based algorithms is too high to be used in practice. In this paper, a lightweight genetic search algorithm (LGSA) is proposed. It can be seen from the simulation results that the performance of the proposed LGSA is not only as good as that of the FSA, but the computational complexity is also much lower than that of the FSA and the other existing genetic motion estimation algorithms.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"123 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125439883","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}

This framework is based on the hierarchical time stream Petri net (HTSPN) model adapted to the specification of temporal and logical constraints in distributed hypermedia systems. The interpreted HTSPN model presented in the paper allows the accurate and unambiguous specification of hypermedia documents. Moreover, it permits powerful analysis techniques to be applied for insuring the quality of hypermedia documents. It is important for a HTSPN specification to be stored, exchanged and presented within open hypermedia systems. Therefore, a procedure for translating interpreted HTSPN specification into an MHEG (Multimedia and Hypermedia Experts Group) representation is also proposed.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124909731","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}

Much work has been done in order to provide system support that meets these requirements. However, existing proposals do not include the consequences of failure occurrence on QoS. In this paper, we address this issue by introducing a resource reservation model that integrates availability requirements. Our design goals for this model were: (i) to allow programmers to reserve resources with respect to various QoS requirements including availability; and (ii) to preserve the transparency of mechanisms used for availability. This paper details the resulting model, together with its integration in a distributed system.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125141746","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}

Most of the previous VOD scheduling approaches use limited run time information, and thus cannot exploit the potential capacity fully. Our approach improves throughput by making use of run time information to relax admission control, and to reduce admission to start delay by providing earliest initial service. We establish conditions for greedy admission, dynamic control of the sequence and sizes of disk accesses, and fast initial service. We conduct thorough simulations over a wide range of buffer capacities, load settings, and over varying playout rates to demonstrate the significant improvements in throughput and admission re start delay of our approach relative to a typical static approach which does not use run time information.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116564295","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}

We use a combination of multiple media for effective communication. To realize this mechanism as a hyper-medium, we propose a noble idea of media integration. First, the correlation between the two media is analyzed to automatically interpret the semantic structure of both media. The integrated hypermedia obtained as a result of the correspondence and the semantic interpretation is quite useful to derive knowledge about topics being described. To demonstrate the usefulness of the integrated media, we have constructed a prototype system for flexible explanation generation. Various kinds of explanation can be generated in our system.","PeriodicalId":371043,"journal":{"name":"Proceedings of the Third IEEE International Conference on Multimedia Computing and Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128861061","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}
