    • An access node comprises a control unit that determines an anticipated working set of television channels based on a historically delivered working set of television channels to which a subscriber network has previously subscribed. The anticipated working set indicates a time at which the subscriber network is expected to subscribe to a different set of channels. The access node includes at least one interface that couples the access node to the subscriber network, that prior to the time at which the subscriber network is expected to subscribe to the different set of channels, subscribes to the different set of television channels in accordance with the anticipated working set such that media content associated with the different channels of the anticipated working set is available for delivery to the subscriber network at the time during which the access node expects the subscriber network to subscribe to the different set of channels.
    • 接入节点包括控制单元,该控制单元基于用户网络先前已经订阅的电视频道的历史传递的工作集来确定电视频道的预期工作集。 预期的工作集表示订户网络预期订阅不同的信道集合的时间。 接入节点包括将接入节点耦合到用户网络的至少一个接口,在用户网络预期订阅不同的信道集合的时间之前,根据接入节点订阅不同的电视信道集合 所述预期工作集合使得与所述预期工作集合的不同信道相关联的媒体内容可用于在所述接入节点期望所述订户网络订阅所述不同信道集合的时间期间传送到所述用户网络。
