运用MPEG-Ⅱ数字视频压缩技术,提高了视频数据压缩效率,降低了信号传输成本,节约了大量的存储空间,特别是MPEG-Ⅱ格式的标准化和兼容性,为架设大规模的数字化电视台系统提供了坚实的基础。当人们面对进一步的规模化网络、数据链路交换分配、大规模数字化存储、多通道数字播出以及DVB直接接收、DVB播出、宽带网上电视的直接数字化链接和交互电视等一系列课题时,基于Motion-JPEG的非线性编辑网络系统已无法回答,人们不约而同地将
The use of MPEG-II digital video compression technology to improve video data compression efficiency, reducing signal transmission costs, saving a lot of storage space, especially the MPEG-Ⅱ format standardization and compatibility, for the establishment of large-scale digital television system provides A solid foundation. When faced with a series of issues such as further large-scale networks, data link switching distribution, large-scale digital storage, multi-channel digital broadcast and direct DVB reception, DVB broadcast, direct digital link for broadband internet TV and interactive television , Motion-JPEG based non-linear editing network system has been unable to answer, people invariably will
