摘要： A method and system for delivering data over a network to a large number of clients, which may be suitable for building large-scale Video-on-Demand (VOD) systems, are provided. In current VOD systems, the client may suffer from a long latency before starting to receive the requested data that is capable of providing sufficient interactive functions, or the reverse, without significantly increasing the network load. The method utilizes two groups of data streams, one responsible for minimizing latency while the other one provides the required interactive functions. In the anti-latency data group, uniform, non-uniform, or hierarchical staggered stream intervals may be used. The system may have a relatively small startup latency while users may enjoy most of the interactive functions that are typical of video recorders. The method and system may also maintain the number of data streams, and therefore, the bandwidth, required.
摘要翻译：提供了一种用于通过网络将数据传送到大量客户端的方法和系统，其可适用于构建大规模视频点播（VOD）系统。在当前的VOD系统中，在开始接收能够提供足够的交互功能的所请求的数据之前，客户端可能会遇到长时间的延迟，或者相反，而不会显着增加网络负载。该方法利用两组数据流，一组负责最小化延迟，另一组则提供所需的交互功能。在反潜时数据组中，可以使用均匀，不均匀或分层交错的流间隔。系统可能具有相对较小的启动延迟，而用户可以享受大多数典型的录像机的交互功能。该方法和系统还可以保持数据流的数量，并因此保持所需的带宽。
