While image quality in conventional MPEG-2 broadcasting is limited by the available transmission capacity, we propose using TV sets with digital storing devices to create a much higher virtual bandwidth that allows for high quality transmissions. Furthermore, both services are backward compatible, that is ordinary TV sets without such storage devices will still be able to receive regular program, although at a lower quality.","PeriodicalId":265329,"journal":{"name":"MULTIMEDIA '99","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133349134","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 technique compactly summarizes a video data by preserving its original temporal characteristics (visual activity) and semantically essential information. It relies on an adaptive nonlinear sampling. The local sampling rate is directly proportional to the amount of visual’ activity in localized sub-shot units of the video. The resulting video abstract is highly compact. To get very short, yet semantically meaningful summaries, we propose an event-oriented abstraction scheme, in which two semantic events; emotionaldialogue and violentfeatured action, are characterized and abstracted into the video summary before all other events. If the length of the summary permits, other non key events are then added.","PeriodicalId":265329,"journal":{"name":"MULTIMEDIA '99","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127270336","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}

If the redundant frame is also lost, the previous frame is repeated for error concealment.

An important aspect we should consider when designing an agent is that how it is regarded by users. Through the appropriate mechanisms we should permit the users’ suspension of disbelief for agents and give users the conviction that they can communicate with a computer efficiently and friendly by intervention of agents. We present here some preliminary works, a generalized and extended framework for the generation of emotions in anthropomorphic agents. A basic idea of the model is placed on the cognitive appraisal model, but it is extended to include other emotion eliciting factors, which are conventionally accepted that they are closely related to the generation of emotions. By representing the structure of the cognitive theory as a simple weighted network, the method provides a flexible way of modeling different aspects of personalities and temperaments.","PeriodicalId":265329,"journal":{"name":"MULTIMEDIA '99","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124927461","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}

Due to the efficient compression achieved by the MPEG-4 standard, parts of the bitstream show high interdependencies. Consequently, without any precautions packet loss within the transmission of a video session severely affects the video quality. Based on the error resilience tools already provided by the MPEG-4 video coding standard, we define an RTP payload format for MPEG-4 video streams and appropriate frag mentation rules. Furthermore, we present experimental results to evaluate the overall robustness of the approach.","PeriodicalId":265329,"journal":{"name":"MULTIMEDIA '99","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125616265","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, present day video server architectures continue to focus primarily on disk and network strategies for maximizing the number of concurrent streams while adhering to Quality of Service (QoS) requirements, If video servers are to manage large numbers of disparate streams exploiting a wide variety of processing algorithms, server architectures must be extended to support the integration of arbitrary isochronous processing algorithms. We believe server support for these stream processing graphs present new research challenges in video server buffer management, distributed stream control and QoS management. In this paper, we propose distributed stream control techniques which form a foundation for developing technology to address these new challenges. We have implemented the recommended techniques in the context of a commercial video server.","PeriodicalId":265329,"journal":{"name":"MULTIMEDIA '99","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123038319","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}
