This is in sharp contrast to the traditional data-driven style almost universally adopted. The time-driven approach can take advantage of the multiple communication channels of various quality-of-service levels that will be supported by ATM networks. Such applications can rely on and take advantage of forms of hierarchical coding for handling real-time continuous media (e.g., video, image animations, audio, etc.) effectively and efficiently. In many such cases (e.g., image database browsing), timely presentation is more important than lossless presentation. The use of hierarchical coding by applications will allow the network to intelligently discard traffic of lesser importance to the applications at times of high congestion, and will thus allow networks to operate at higher degrees of statistical multiplexing without causing problems for the integrity of the most important signal components. We present some initial performance results of a simple hierarchically encoded image animation in a local ATM environment, including some results of the image quality when loss is experienced.","PeriodicalId":196946,"journal":{"name":"5th IEEE COMSOC International Workshop on Multimedia Communications","volume":"67 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127338994","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}

For the widespread use of the multimedia applications, a local area network (LAN) must support communication needed to transfer both types of media. A LAN based on the asynchronous transfer mode technology is considered to be promising as a candidate for a multimedia LAN. Especially, an ATM switching system is regarded as adequate for the reason that it has scalability in the capacity. However, though many researchers are studying how to offer a connectionless service, how to achieve fast and fair dynamic bandwidth allocation and so forth in the ATM switching system, these issues are not completely resolved. For another approach, we are developing a shared-media LAN based upon the ATM technology. The ATM ring (ATMR), which is a shared-media ATM-LAN, is evaluated as a multimedia LAN. Requirements for a multimedia LAN are described, and the current issues of the ATM switching system are described. The ATMR protocol and its characteristics are explained and the ATMR prototype is assessed. Finally, the future work and conclusions are presented.","PeriodicalId":196946,"journal":{"name":"5th IEEE COMSOC International Workshop on Multimedia Communications","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134375615","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}

One powerful presentation control capability is to allow users to 'associate' multimedia streams together in unique, customized ways. Associating media streams with each other allows a user to create what might be thought of as composite or meta multimedia object. This mechanism can be used to synchronize the delivery of different multimedia streams in order to achieve some presentation goal. A multimedia provider may want to synchronize information from different servers, as the provider may not have the capacity to store all the necessary information, or may not have the copyright to certain information. A user may also want to associate different video images together in order to compose a video scene. This might be used to associate the images being sent by an array of cameras to give a panoramic view, or to enable a user to group other users of a teleconference. The teleconferencing user could then view a subset of the other conferees and have a convenient way to access different conferees' images by simply panning left or right on the combined video scene. Users could also be grouped together by role for easy access.","PeriodicalId":196946,"journal":{"name":"5th IEEE COMSOC International Workshop on Multimedia Communications","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128678315","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}
