【摘要】 针对目前的HFC的频带资源被大量闲置的问题,文章设计了一套基于HFC的VOD系统,此系统通过IP/QAM设备,将千兆网络带宽划分为24个8MHz的频道,从而实现通过HFC实施支持交互式与广播式等多种多媒体通信应用。文章介绍了基于HFC网络的VOD系统设计与实现方案。更多还原

【Abstract】 Aiming at the issue that current HFC resources are idled in large quantity,a VOD system based on HFC is designed in this article.The system uses IP/QAM equipment to divide the bandwidth of a gigabit network into 24 channels of 8MHz,and thus implement a variety of interactive and broadcast multimedia communications applications supported by HFC.And the article describes the VOD system based on the HFC network design and implementation method.更多还原
