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}

Video streams must be secure in order to prevent unauthorized viewing of the programs being transmitted, yet most existing security systems do not make use of the potential for bidirectional signalling in new and upgraded networks. 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}

Our goals are two fold: maximizing the number of concurrent real time sessions while minimizing the buffering requirements, and ensuring a high degree of reliability. The first goal is achieved by adopting a pipelined approach and by reducing latencies through specialized disk caching and constrained data placement schemes. The second goal is achieved by dividing the disks into RAID 3 reliability groups which serve as pipeline stages. We note that the buffering requirement decreases as the number of groups increases. To improve the performance further, we introduce two techniques for more efficient movie retrieval: on arrival caching, and interleaved annular layout. We present a case study of the performance of these techniques which shows a significant improvement when they are incorporated.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"10 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":"125430157","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 development of optical storage and compression/decompression technologies means that millions of pieces of multimedia information can be readily diffused and transmitted to people who intend to acquire those information to become their knowledge. But does this type of computer-supported learning system necessarily improve the effectiveness of learning? The paper proposes a theoretical framework which can be used to study the value of multimedia knowledge diffusion, i.e. where knowledge is transmitted from a sender through communication channels for a receiver to internalize and retain these information. We also discuss the findings of an experiment in evaluating the effectiveness of multimedia in enhancing people's learning ability.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"14 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":"126983007","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 effectively utilize a disk array and hence to maximize the number of clients that can be serviced simultaneously, a multimedia server must interleave the storage of each media stream among the disks in the array. We identify two placement policies for organizing storage of multimedia objects on disk arrays. We present methods for optimizing the performance of server for both the placement policies, and empirically validate and evaluate the methods through extensive trace driven simulation.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"193 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":"128436068","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}

Digital multimedia, together with CD ROM technology now enables production of interactive textbooks and dictionaries for sign languages on personal computers. The paper presents the key technological and contents requirements for learning to sign from a point of view of deaf as well as hearing persons. The technological requirements are then measured up with the current Multimedia PC Level 2 specifications. An alternative representation for sign language based on edge images derived from sequences of video frames is proposed to achieve higher video compression ratios. The fulfilment of contents requirements is demonstrated by an example of the Sign Language Dictionary and Tutor.","PeriodicalId":423754,"journal":{"name":"Proceedings of the International Conference on Multimedia Computing and Systems","volume":"159 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":"127388383","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}
