    Abstract: Automated data-matching includes obtaining first and second stored fingerprints generated from first and second data. The stored fingerprints are divided into frames, and grouped into first blocks and second blocks including an equal number of frames. Each frame included in a current first block is compared to each frame included in a current second block to determine a number of matching frames, and a hamming distance between the current first block and the current second block is determined, based at least in part on the number of matching frames. A determination is made, based at least in part on the hamming distance, whether the current first block and the current second block match.

    Abstract: A syndicated-content recognition system retrieves, from at least one database, media broadcast files broadcast by a plurality of media broadcast sources, wherein individual media broadcast files are associated with stations, days of the week, and times. Based on historical data associated with the media broadcast files, the system determines whether a particular media broadcast file associated with a particular station and a particular time is likely to include syndicated content. In response to determining that the particular media broadcast file is likely to include syndicated content the particular media broadcast file is tagged to generate a tagged media broadcast file, and the tagged media broadcast file is exempted from syndicated-content-comparisons with other media broadcast files.

    Abstract: Content from multiple different sources can be divided into segments based on time. Matched segments associated with each source can be identified by comparing content included in a first segment associated with a first source, to content included in a second segment associated with a second source. Syndicated content can be identified and tagged based, at least in part, on a relationship between sequences of matched segments on different stations. Various embodiments also include identifying main sequences associated with each source under consideration, removing some of the main sequences, and consolidating remaining main sequences based on various threshold criteria.

    Abstract: First fingerprint data is accumulated in a first fingerprint buffer of a channel identification server in parallel with accumulation of second fingerprint data in a second fingerprint buffer of the channel identification server. The first and second fingerprint data include multiple fingerprints representing broadcast content broadcast by corresponding broadcast sources during contiguous time periods, and accumulating the fingerprints includes appending newly received first fingerprints to previously received first fingerprints to generate continuous fingerprints. The channel identification server also receives an unmatched fingerprint representing broadcast content received from an unknown broadcast source by the end-user device. The unmatched fingerprint into probes, which are scrubbed against both first and second continuous fingerprints in an attempt to determine a match between the unmatched fingerprint and either the first or second continuous fingerprint. The unknown broadcast source is identified based on that determination.

    Abstract: An application client receives an open window event from an intermediary device before transmitting a licensing request to the intermediary device. The intermediary device transmits the licensing request to an authentication server, which responds by transmitting a message indicating approval status of the request back to the intermediary device. If the intermediary device is not within a predetermined proximity of the application client, the intermediary can wait predetermined amount of time for the intermediary device to return to the predetermined proximity of the application client before transmitting a second message indicating approval status to the application client. The application client receives, from the intermediary device, a licensing response reporting the approval status indicated by the message from the authentication server.

    Abstract: A server machine obtains media content information and event records, which include session data. The session data including consumer identifiers identifying consumers, and content provider identifiers identifying media stations. The server uses the event records and the media content information to generate tune-away events when first session data includes a first content provider identifier, but subsequent session data includes a second content provider identifier different from the first content provider identifier. The server aggregates tune-away events for a specific program across multiple different media outlets to determine a total number of tune away events for that program during a specified time period. The total number of tune-away events can be transmitted to an end user machine, which can display a graphical representation.

    Abstract: Small changes in a broadcast version of a base media item can be identified by performing a multi-level comparison of digital fingerprints. A fingerprint of a base media item is compared to a fingerprint of a media broadcast to determine whether a media item embedded in a broadcast is likely, to a first level of certainty, to be the base media item. A second, more stringent, match between the fingerprint of the base media item and loosely matched items can be used to identify potentially-altered versions of the base media item. Potentially-altered versions can be compared against each other, and resulting matches are flagged as altered base media items, which can be fingerprinted and tested against broadcast fingerprints in the same manner as the base media item.

    Abstract translation: 可以通过执行数字指纹的多级比较来识别基本媒体项的广播版本的小变化。 将基本媒体项目的指纹与媒体广播的指纹进行比较,以确定嵌入在广播中的媒体项目是否可能成为基本媒体项目的第一级别。 可以使用基本媒体项目的指纹和松散匹配的项目之间的第二个更严格的匹配来识别基本媒体项目的潜在改变的版本。 潜在改变的版本可以彼此比较,并且所得到的匹配被标记为改变的基本媒体项目,其可以以与基本媒体项目相同的方式针对广播指纹进行指纹和测试。
