9405601 El Zarki这项研究的目标是为高比特率视频应用提出/推荐增强的服务选择，以改善它们在基于ATM的BISDN上的传输。为了做到这一点，研究人员将详细研究编码过程，以更好地了解服务的潜在特征。重点放在新出现的标准MPEGII上。MPEGII包含一个非常复杂的编码过程，其中包含几个不同的选项。这些选项对ATM网络上的视频数据传输的影响尚未被研究。研究计划包括详细研究这些不同的编码选项，然后研究用于传输打包视频数据的网络接入和控制方案。这项研究将包括：1)研究用于高比特率视频服务的不同编码和差错恢复选择；2)研究各种视频服务的来源特性和网络控制和接入方案，以便在基于ATM的网络上传输。***

9405601 El Zarki The goal of this research is to propose/recommend enhanced service options for high bit rate video applications to improve their transmission over ATM-based BISDN. To do that the researchers will study the encoding process in detail to understand better the underlying characteristics of the service. The focus is on the newly emerging standard MPEG II. MPEG II encompasses a very complex encoding process that incorporates several different options. The impact of these options on the transmission of video data over an ATM network has not yet been studied. The research plan involves studying these different encoding options in detail and then investigating network access and control schemes for the transmission of packetized video data. The research will include 1) the investigation of different coding and error recovery options for high bit rate video services and 2) the study of the source characteristics and investigation of network control and access schemes for a variety of video services for transport over ATM-based networks. ***
