Digital content, such as video, audio, multimedia, and similar files may be segmented at a determined frame resolution rate and analyzed to determine a fingerprint for each content segment. An identifier that uniquely identifies each content segment may be determined based on the fingerprint of the respective content segment. The identifier may be associated with data relating to the content segment and with one or more identifiers that uniquely identify other content segments of the content. The content segment identifiers may be used to construct a content segment sequencing representation that represents the playback of the content segments in playback order.

The addition of relative term positions, temporal positions, and segment identifiers to an inverted index allows for temporal and phrase queries of multimedia assets. Segment identifiers enable any search results to be examined in context. The system makes advantageous use of Lucene's binary payload functionality to store temporal data and segment identifiers as additional binary data for each term instance in the inverted index. The payloads are made up of three variable-length integers, which account for twelve extra bytes of metadata, which are stored for each term instance. A content database on a Master / Administrator server node provides the indexes for search into content in response to user events, returning results in JSON format. The search results may then be used to locate and present content segments to a user containing both requested search term results and the time location within the multimedia asset in which the search term(s) is found.

An apparatus for diagnosing sleep disorders such as OASHS from snore sounds includes a segmentation module (126) coupled to a data logger (124) to provide segments of the digitized audio signal to a Snore Segment Identifier (128). A total airways response (TAR) module (130), pitch calculator (132) and MFCC calculator (134) are each coupled to an output side of the snore segment identifier module (128). Each of these modules is respectively arranged to calculate pitch, bispectrum, diagonal slice and MFCC parameters for the snore segments received from the snore segment identifier (128). Similarly, the NGI calculator (136) produces a non-Gaussianity index for the digitized audio signal. A classification module (144) is arranged to process the calculated parameters and compare a resulting diagnosis probability to a predetermined threshold value. The results of this comparison are then indicated on video display (142), which communicates with the classification module (133) via display controller (140) and bus (145). For example, if the results of the comparison are over threshold then display (142) is driven to indicate “OS AHS is present”.

A hierarchical document cross-reference system comprises a document server computer remotely accessible by a user computer. The document server computer includes a database which stores the contents of a first document and a second document. The first document contains one or more segments and the second document contains one or more segments. Each segment is identified by a segment identifier. The document server computer also includes a module executable in the document server computer. The module is configured to receive a request to cross-reference the first document and the second document on a key phrase. The module searches the first document and the second document for the key phrase and identifies the segments in the documents containing the key phrase. The module then displays on the user computer a side-by-side display listing the segment identifiers for the identified segments. The segment identifiers for the identified segments in the first document containing the key phrase are displayed in a first list and the segment identifiers for the identified segments in the second document containing the key phrase are displayed in a second list. The user can subsequently select a segment identifier from each list and submit the segment identifiers for display. The module then displays the contents of each segment, with the key phrase highlighted in a distinct color or by other means.
