    • A method and system for sharing search index entries across multiple computer systems organized in a peer to peer network, in which unique content is indexed only once, even though the content may be physically duplicated in multiple computer systems in the peer to peer network. When files are obtained by a shared indexing service, and a determination is made as to whether the received files are duplicates with regard to previously indexed files. If a file is determined to be a duplicate, the index representation of the previously indexed copy of the file is modified to indicate that the file is also associated with another computer system in the peer to peer network. If a file is not a duplicate of a previously indexed file, the file is indexed to support future searches. The index representation of a file includes category identifiers associating one or more computer systems with the file. When a file is indexed, one or more category identifiers are generated and stored in association with that file. The category identifiers for an indexed file may represent host computer systems on which copies of the file are stored. The category identifiers enable location specific searching by computer systems in a peer to peer network sharing a common search index. A software category filter may be provided to process search results from the shared search index, so that only files associated with certain categories are returned.
    • 一种用于在组织在对等网络中的多个计算机系统上共享搜索索引条目的方法和系统,其中唯一内容仅被索引一次,即使该内容可以在对等网络中的多个计算机系统中物理复制。 当通过共享索引服务获得文件时,并且确定所接收的文件是否是关于先前索引的文件的重复的。 如果确定文件是重复的,则修改文件的先前索引副本的索引表示,以指示文件也与对等网络中的另一计算机系统相关联。 如果文件不是以前索引的文件的副本,则将该文件编入索引以支持将来的搜索。 文件的索引表示包括将一个或多个计算机系统与文件相关联的类别标识符。 当文件被索引时,生成一个或多个类别标识符并与该文件相关联地存储。 索引文件的类别标识符可以表示存储文件副本的主机系统。 类别标识符使得在对等网络中的计算机系统进行位置特定搜索共享公共搜索索引。 可以提供软件类别过滤器来处理来自共享搜索索引的搜索结果,使得仅返回与某些类别相关联的文件。

    • In the recording of broadcast television text, the text is separated from the video signal and formed into blocks at slicer and then is fed into shift register. It is then taken out at a data rate lower than that when broadcast and coding is assigned to at least some of the blocks prior to recording onto a video cassette tape recorder. Retrieval and display incorporate similar functions in reverse order. In another embodiment data in block form is stored on a video disk for similar retrieval and display.
    • 在广播电视文本的录制中,文本与视频信号分离,并在分片器处形成块,然后馈送到移位寄存器中。 然后以比将广播和编码分配给至少一些块之前的数据速率低的数据速率取出,然后再将其记录到盒式磁带录像机上。 检索和显示以相反的顺序结合相似的功能。 在另一实施例中,块形式的数据被存储在用于类似的检索和显示的视频盘上。
