摘要： A channel merging method for a video on demand system, said method comprises the steps of: in response to requests from a plurality of clients for a video program, establishing a root channel (S1) and at least one sub-channel (S11), said root channel (S1) being established according to a request from a client that makes the earliest request, each of said sub-channels (S11) being established in response to a request from a client that makes a later request; and monitoring variation of the number of the clients that are using each of said established channels, and maintaining the channel if the number of the clients using the monitored channel is not zero, and closing the channel if the number of the clients using the monitored channel becomes zero.
摘要翻译：一种用于视频点播系统的信道合并方法，所述方法包括以下步骤：响应多个客户端对视频节目的请求，建立根信道（S1）和至少一个子信道（S11），所述根信道（S1）根据来自最早请求的客户端的请求建立，每个所述子信道（S11）响应于来自客户端的稍后请求的请求而被建立; 以及监视正在使用每个所述建立的信道的客户端的数量的变化，以及如果使用所监视的信道的客户端的数量不为零，则维持该信道，并且如果使用所监视的信道的客户端的数量，则关闭该信道变成零。
