It should also cope with dynamic changes in workload and heterogeneity arising from large and small multimedia files. We conclude with a new applicationdependent multilocation multi-demand synchronization framework to address these new challenges. We introduce the application Synchronization in the context of multimedia computing deals with timing issues within and among media. A prototype system has been conducted to evaluate the effectiveness of the approach. © International Forum of Educational Technology & Society (IFETS). We can identify two types of media synchronization control: Object (or event-driven) and continuous synchronization control (Campbell et al., 1992). The main focus and contribution of the paper is in scheduling and admission-control algorithms for accessing the server's processor and storage resources.

This is called multimedia synchronization and can be achieved by putting time stamps in every media packet. So far, there has been considerable research attention on the working principles behind synchronization phenomena in nature and, as a result, various models and theoretical investigation have been developed to apply synchronization princ… as a logically coherent unit. Over the years, many media sync solutions have been devised. In this paper we present a media-streaming system, called Bamba, that delivers audio and video over low-bandwidth modem connections with the use of standard compression technologies. variability (i.e., statistically significant process shifts as opposed There is a lack of extant research to address the critical issue of how to develop effective multimedia instructional content that leads to desirable learning performance and satisfaction.

The scheduling algorithms support multiple classes of tasks with diverse performance requirements and allow for the co-existence of guaranteed real-time requests with sporadic, and unsolicited requests. The problems associated with multimedia synchronization can be, and have been, approached from many perspectives. For routing of requests, we introduce the notion of an asset group and propose an affinity routing policy based on this concept. One of the most significant problems in conventional subsystems is provision of high-speed protocol processing. %��������� statistical quality control (i.e., controlled variability around a The advances on multimedia systems have brought new challenges and requirements for media sync.
