Abstract: Example methods and systems for computing a reaction time from an indexed event occurring in an indexed recording to a reaction signal are described. An example method includes receiving a sample of ambient content of a computing device, determining a position identification of the sample of ambient content into an indexed recording to which the sample of ambient content matches, based on the position identification, synchronizing display of content on a user interface of the computing device to the indexed recording, and computing the reaction time. The reaction signal is generated by the computing device and is indicative of a user's response to the indexed event.

Abstract: An example method for performing playout of multiple media recordings includes receiving a plurality of media recordings, indexing the plurality of media recordings for storage into a database, dividing each of the plurality of media recordings into multiple segments, and for each segment of each media recording, (i) comparing the segment with the indexed plurality of media recordings stored in the database to determine one or more matches to the segment, and (ii) determining a relative time offset of the segment within each matched media recording. Following, the method includes performing playout of a representation of the plurality of media recordings based on the relative time offset of each matched segment.

Abstract: Methods and systems for arranging and searching a database of media content recordings are provided. In one example, a method is provided that comprises receiving a sample of media content, and performing, by a computing device, a content recognition of the sample of media content using a data file including a concatenation of representations for each of a plurality of media content recordings. In other examples, another method is provided that comprises receiving media content recordings, determining a representation for each media content recording, concatenating by a computing device the representation for each media content recording as a data file, and storing by the computing device a mapping between an identifier for a respective media content recording and a global position in the data file that corresponds to the representation of the respective media content recording.

Abstract: Methods and systems for identifying information of a broadcast station and information of broadcasted content are provided. In one example, a method includes receiving at a client device media content rendered by a media rendering source, and the client device making an attempt to determine an identity of the media content based on information stored on the client device. The method also includes based on the attempt of the client device to determine the identity of the media content, determining an identity of the media rendering source. The method further includes based on the attempt of the client device to determine the identity of the media content and on determining the identity of the media rendering source, sending information indicative of the media content to a content recognition server to determine the identity of the media content.
