    • A subscriber or other user is provided with access to a subscription service of a signal distribution system at a location remote from a home location of the user. The subscription service comprises a plurality of selectable channels available to the user at the home location. The user is assigned one of a plurality of program streams utilizable for delivery of content from the head end equipment servicing the remote location to an interface device at the remote location. By way of example, the program streams may be part of existing unicast infrastructure in the head end equipment. The head end equipment obtains content for a first channel of the subscription service available to the user at the home location, and inserts the content for the first channel into the assigned program stream to thereby make that content accessible to the user at the remote location via the interface device. User selection via the remote location interface device of a different channel of the subscription service available to the user at the home location causes the content for the different channel to be obtained by the head end equipment and inserted into the assigned program stream in place of the content for the first channel.
    • 用户或其他用户被提供对远离用户的本地位置的位置的信号分发系统的订阅服务的访问。 订阅服务包括在家庭位置可用于用户的多个可选择的频道。 用户被分配为可用于从服务于远程位置的头端设备向远程位置的接口设备传送内容的多个节目流中的一个。 作为示例,节目流可以是头端设备中的现有单播基础设施的一部分。 头端设备获得用于家庭可​​用的订阅服务的第一频道的内容,并将用于第一频道的内容插入分配的节目流中,从而使该用户可以在远程位置通过用户访问内容 接口设备。 通过远程位置接口设备对用户在归属位置可用的订阅服务的不同频道进行的用户选择使得头端设备获得用于不同信道的内容,并将其插入分配的节目流中,代替 第一个频道的内容。

    • Advertisements or other types of targeted information are delivered to a set-top box (112) or other user interface device of signal distribution system, in one aspect of the invention,' a detection server (202) of the system detects (1) at least one cue associated with a first media stream, and generates timing information from the detected cue. The timing information is signaled (3) to the interface device. An advertisement server (204) of the system generates a second media stream containing targeted information for delivery (5) to the user interface device. The user interface device switches from the first stream to the second stream based on the timing information. The timing information may also be signaled (2) by the detection server to the advertisement server, for use in controlling generation of the second stream.
    • 在本发明的一个方面,广告或其他类型的目标信息被传递到信号分配系统的机顶盒(112)或其他用户接口设备,“系统的检测服务器(202)检测(1) 与第一媒体流相关联的至少一个提示,并且从检测到的提示生成定时信息。 定时信息(3)发信号给接口设备。 系统的广告服务器(204)生成包含用于传送(5)的目标信息到用户界面设备的第二媒体流。 用户接口设备基于定时信息从第一流切换到第二流。 定时信息也可以由检测服务器向广告服务器通知(2),以用于控制第二流的产生。
