Multimedia technology offers new opportunities but there are complex problems to solve, in particular with regard to data structure and data logistics, and interactive user interface design for casual users. The CIN enables users to get information comprised of text, photos, pictures, voice, and video elements in a multimedia kiosk, to search for the required information via a full-text retrieval from the frequently updated database. Original features of the approach of Bremen concern a public-private partnership and cost-sharing between a tourist and a citizen information system as well as a technical open client server architecture. The creation of such a system is a software and organization development process.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"11 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":"129804530","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}

However, for the very reason that hypertext allows knowledge construction through exploration, it stimulates talented students but tends to penalize those less skilled in self-managing their learning process. We present HYPEREX, an intelligent, hypertext system realized in TOOLBOOK and OPENSCRlPT environments, which proposes exercises on the Pascal programming language, with a tutorial component which can guide the student by pointing out any gaps or incorrect knowledge he may have. Artificial intelligence techniques have been integrated with hypertext technology to enable both free navigation in the hypertext and system intervention on request.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"37 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":"132035504","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 shortcomings of this approach are the lack of flexibility in re-negotiating bandwidth parameters after connection establishment and the inability to react to changing server load conditions. In this paper, we propose a \"selected access scheme\" for re-negotiating continuous media delivery from a video-on-demand server. We consider the overall system perspective on resource availability rather than a per-connection resource management scheme. The selected access scheme is combined with data placement strategies for the server to dynamically access desired video frames from a shared storage device. This approach is especially suitable for video data compressed and stored using an inter-frame encoding scheme such as specified by the MPEG standard. Simulation results show that the proposed model can utilize server bandwidth, improve the reliability of playback, reduce the buffering needed and support VCR-like functions without blocking user access to the storage device.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"32 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":"132076787","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}

Although it has been estimated that 20% of patients visiting physicians qualify for an alcoholic diagnosis, the early stages of excessive drinking often remain unrecognized in general medical practice and in hospitals due to inadequate training and erroneous stereotyping. To address this problem, the American Research Corporation of Virginia (ARCOVA) is developing the Interactive Multimedia Program for Alcoholism Assessment and Counseling Training (IMPACT), a combination of audiovisual media and programmed interaction for the teaching of alcoholism management skills to physicians and nurses at both the student and professional levels. The hallmark of this program is a role-play activity with patient personalities simulated by digital audio and video that will respond to questions posed by the user.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"15 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":"129673935","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 propose a method for transforming the standard MPEG stream to a local form at the player device, which then enables the device to support interactive playout even when the buffer space available is constrained. Specifically, we devise a stream conversion scheme that encodes predictive (P) frames as intra (I) frames after the decompression and playout of each P frame. Such a scenario of transforming a P frame to an I frame is termed P-I conversion. Note that since this P-I conversion is performed after a P frame is decompressed and played out, there is no extra cost required for decoding. Also, since there is no motion estimation and compensation required for compressing a single frame into an I frame, this I frame encoding is done very efficiently. We have evaluated several potential interactive playout methods using video experiments. P-I conversion is shown to be cost-effective, easy to implement, and able to provide interactive playout with high visual quality, and is therefore deemed a viable approach to supporting interactive playout for MPEG video in a client station.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"60 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":"126686220","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 would prove more useful to many companies if they could use one system to test a number of different distribution networks to see if they save an acceptable quality of service. In this manner, a company could decide if existing networks could be used without substantial changes, or whether expensive upgrades or indeed replacements were justified.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"43 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":"134024264","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}

Synchronization of multiple data streams in time has thus been recognized as a crucial requirement for multimedia applications. We study the synchronization requirements among distributed multimedia objects. We describe a temporal model that deals with interstream and intrastream synchronization requirements in live media objects. Both the blocking policy and the restricted blocking policy are presented. In addition, our model handles the accurate and uncertain temporal requirements which may exist in the teleorchestration of fuzzy scenarios. The fuzzy scenarios that contain imprecise synchronization constraints, such as unknown object presentation starting or ending points, can be transformed into more accurate temporal specifications. The paper provides several examples to show our approach.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"24 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":"133371799","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}
