This paper presents a probabilistic approach for analyzing admission control and communication establishment for the general class of non-preemptive deadline-oriented packet scheduling policies. The prediction method can be used for communication and scheduling policy evaluation, routing for multimedia traffic and capacity planning. A large-scale simulation study demonstrates that our method provides highly accurate predictions of acceptance rates for multiple types of multimedia connection requests.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117078719","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 model consists of three layers: a runtime layer (RTL) a document description layer (DOCDL) and a storage layer (SRL). The DOCDL contributes to defining the logical structure. It not only constrains the structure of the SRL, but also forms a bridge between the RTL and the SRL. In the DOCDL, an extended open document architecture (ODA) is employed for describing the logical structure of the document. In addition, we present a technique for automatically generating and updating database schema given a document logical structure. For the RTL, the document logical structure is visualized to help users to retrieve information, and as a means for multimedia data capture. The advantages and benefits of this approach are to allow the design and implementation of hypermedia systems to be automated and much simplified. The approach also caters for the continuous updating of the document logical structure such as adding an extra data object. The paper applies the proposed model to the design and implementation of a multimedia document system for medical documents.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125016533","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}

Accessing these catalogues raises a problem for users and content providers, that we define as the music selection problem. We introduce three main goals to be satisfied in music selection: match user preferences, provide users with new music, and exploit the catalogue in an optimal fashion. We propose a novel approach to music selection, based on computing coherent sequences of music titles, and show that this amounts to solving a combinatorial pattern generation problem. We propose constraint satisfaction techniques to solve it. The resulting system is an enabling technology to build better music delivery services.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123602649","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 Information Society Technologies programme brings to the foreground the concept of convergence. Convergence between technologies but also between technology and the commercial and regulatory requirements to enable open global markets. The former industrial pre-competitive European R&D programmes, RACE (Research and Development in Advanced Communications in Europe) and ACTS (Advanced Communications Technologies and Services), maintained a strong symbiotic relationship with standardisation. Through mechanisms put in place during the lifetime of the programme the various research projects were clustered in concertation groups to harmonise approaches leading to clear and stronger contributions in the different standardisation organisation/consortia. The expectations are that standardisation in the networked multimedia domain works as enabler of market openness and fairness, public interest and social-cultural awareness (in the sense of taking into account the end-user as an individual or community) leading to a non-obstructive competitive attitude. This paper lists a non-exhaustive set of points in telecommunication and information technology where we believe R&D and standardisation must find a sustained input/output flow of background technological work and consensus-building mechanisms to achieve the above mentioned objectives.","PeriodicalId":408680,"journal":{"name":"Proceedings IEEE International Conference on Multimedia Computing and Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122169997","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}
