    Abstract: Exemplary embodiments provide methods, mediums, and systems for replicating metafiles between a source and a destination. The metafile may be subdivided into blocks. The contents of the metafile may be transferred by locating the blocks which are changed between the source version of the metafile and the destination version of the metafile. The changed blocks may be examined to retrieve the contents of the changed blocks. The records in the changed blocks may be evaluated to determine whether to create a corresponding record at the destination, delete a corresponding record at the destination, or update a corresponding record atthe destination. Accordingly, the metafile may be replicated in a logical manner, by transferring only changed records rather than the entirety of a changed block. Moreover, the transfer is conducted efficiently because unchanged blocks are eliminated from consideration at the outset.

    Abstract translation: 示例性实施例提供了用于在源和目的地之间复制图元文件的方法，介质和系统。 图元文件可以细分为块。 元文件的内容可以通过定位在元文件的源版本和元文件的目标版本之间改变的块来传送。 可以检查改变的块以检索改变的块的内容。 可以评估改变块中的记录以确定是否在目的地处创建相应的记录，删除目的地处的相应记录，或者更新目的地处的相应记录。 因此，可以通过仅传送改变的记录而不是整个改变的块来以逻辑方式复制图元文件。 而且，转移是有效地进行的，因为从一开始就不考虑未改变的块。

    Abstract: The disclosed system and method receives, from a media device, a query fingerprint that includes an ordered sequence of frames of content being consumed, and matches the query fingerprint with frame fingerprints by determining a distance between respective frame fingerprints and corresponding ones of the ordered sequence of frames. The matching may be performed by populating a binary tree structure with respective distances, chronologically across leaf nodes of the binary tree structure, and then noting a value of the root node. If below a maximum threshold, then there is a match. The system and method may detect a channel change at the media device by traversing a sub-tree of the binary tree structure, and locating a low value (or a zero) at the first or second nodes of the sub-tree. This channel change may be useful in targeting media to content being streamed to the media device.
