    • A method and apparatus for a multicasting multimedia content distribution system. A content server creates a schedule of transmission times for data streams and assigns the streams to multicast groups. DVRs receive the schedule from content server that contains content descriptions for each data stream along with the transmission times of each particular content description. The content server transmits the content across the Internet according to the published schedule via a multicast transmission designated for a particular multicast group. Each DVR determines the content for which it has an interest, finds the scheduled time for transmission for the content, schedules a recording time in its recording schedule, and joins the associated multicast group at the scheduled time. The DVR receives the multicast stream for the group and stores the stream on its local storage device for use by the DVR or for viewing by a user.
    • 一种用于组播多媒体内容分发系统的方法和装置。 内容服务器创建数据流的传输时间调度,并将流分配给多播组。 DVR从内容服务器接收包含每个数据流的内容描述以及每个特定内容描述的传输时间的调度。 内容服务器经由针对特定多播组指定的组播传输,根据所发布的时间表,通过因特网发送内容。 每个DVR确定其感兴趣的内容,找到内容传输的预定时间,在其录制时间表中调度录制时间,并在预定时间加入关联的多播组。 DVR接收该组播组播流,并将该流存储在本地存储设备上供DVR使用或用户观看。

    • An authorized email control system receives email destined for a particular user. Inclusive, temporary and exclusive address books are provided for the user. The inclusive address book lists all the sender email addresses and domains names that the user wants to allow into his mailbox. If the received email message's sender is listed in the user's inclusive or temporary address book then the email is placed in the user's main mailbox. If the sender is listed in the user's exclusive address book, then the message is deleted. The invention truncates the body of the received email message to a user settable length which is sent through at least one extensible message filter that provides a pass/fail indicator and optionally provides reasons for a fail indication. If the truncated email body passes all of the filters, then the sender is added to an accepted sender list. Otherwise, the sender is warned that its email was rejected and the reason(s) why. The sender's domain name is then placed on an unaware domain list. The user is conditionally notified if the sender has been added to the sender list or unaware domain list, giving the user the option to add the sender to his inclusive or exclusive address book.
