    • Systems and methods are provided for obtaining look-ahead segments for a streaming media item during playback such that the viewer can easily skip to the look-ahead segments without experiencing any substantial interruption or delay in playback. In general, a streaming media source begins streaming a media item to a streaming media client for playback. In one embodiment, the streaming media client selects one or more segments of the media item as one or more look-ahead segments to prefetch from the streaming media source. Then, while the media item is being streamed to the streaming media client for playback, the streaming media client prefetches the one or more look-ahead segments of the media item from the streaming media source. The look-ahead segments are thereafter utilized to enable the viewer to skip ahead in playback without experiencing a substantial interruption or delay in playback.

In general, while playing a media item, the media player identifies upcoming content for which the user desires an advance content alert. In response, the media player generates an advance content alert and inserts the advance content alert into the media item during playback. The user may then take an action in response to the advance content alert. In one embodiment, the user may provide input via a remote control of the media player or a mobile device registered with the media player in order to cause a desired action to be taken by the media player in response to the advance content alert.

    • A media broker comprises a communication interface and a controller associated with the communication interface configured to receive a request from a user to record a requested media item. The media broker proceeds to query an aggregated stored content list (ASCL) including information indicative of each of the media items stored on one or more media storage device communicatively coupled to the media broker to determine if the requested media item is stored on the one or more media storage devices. If it is determined that the requested media item is stored on the one or more media storage devices the user that requested the media item is informed and the media item is stored on the one or more media storage devices. Conversely, if it is determined that the requested media item is not stored on the one or more media storage devices, the requested media item is recorded.
    • 媒体代理包括通信接口和与所述通信接口相关联的控制器,所述控制器被配置为接收来自用户的请求以记录所请求的媒体项目。 媒体代理继续查询聚合的存储内容列表(ASCL),其包括指示存储在通信地耦合到媒体代理的一个或多个媒体存储设备上的每个媒体项目的信息,以确定所请求的媒体项目是否存储在该媒体项目的一个或 更多的媒体存储设备。 如果确定所请求的媒体项目被存储在一个或多个媒体存储设备上,则通知请求媒体项目的用户,并且媒体项目被存储在一个或多个媒体存储设备上。 相反,如果确定所请求的媒体项目未被存储在一个或多个媒体存储设备上,则记录所请求的媒体项目。
