| 20120016876 | METHOD AND DEVICE FOR GENERATING AND DETECTING A FINGERPRINT FUNCTIONING AS A TRIGGER MARKER IN A MULTIMEDIA SIGNAL - A device is configured to perform a method that detects a trigger marker for an action corresponding to a segment of a multimedia signal. A fingerprint is generated based on the segment of the multimedia signal at a trigger time point. The generated fingerprint is stored in a database and communicated to the device. During playback of the multimedia signal, fingerprints of segments of the multimedia signal are generated and matched against fingerprints in the database. When a match is found, one or more associated actions for the segment are retrieved by the device. The trigger time point may be determined as a time point near or at the segment of the multimedia signal with the matched fingerprint. In this way, trigger markers for actions may be enabled without modifying the multimedia signal. | 01-19-2012 |

| 20110128444 | METHOD AND DEVICE FOR GENERATING AND DETECTING FINGERPRINTS FOR SYNCHRONIZING AUDIO AND VIDEO - This invention relates to a device and a method of generating a first and a second fingerprint ( | 06-02-2011 |
| 20100325135 | METHODS AND APPARATUS FOR DETERMINING A MOOD PROFILE ASSOCIATED WITH MEDIA DATA - In an embodiment, a method is provided for determining a mood profile of media data. In this method, mood is determined across multiple elements of mood for the media data to create a mood profile associated with the media data. In some embodiments, the mood profile is then used to determine congruencies between one or more pieces of media data. | 12-23-2010 |
| 20100185502 | DYNAMIC MIXED MEDIA PACKAGE - It has been discovered that a dynamic mixed media package with a mechanism for dynamic modification/update provides a media experience to users that exceeds the experience offered by individual media files. A dynamic mixed media package accommodates various types of media and allows for additional media and modifications of existing media. Additional media includes media generated by consumers, such as media derived from a seed media. A seed media is marked and assembled with supplemental media into a package. The seed media is marked to allow performance of various operations, such as identification of the seed media during the lifetime of the package and attribution when the seed media is incorporated into consumer generated derivative media. | 07-22-2010 |
| 20100161656 | MULTIPLE STEP IDENTIFICATION OF RECORDINGS - Multiple information is extracted from an unknown recording and information associated therewith. Associated information includes the filename, if the recording is a computer file in, e.g., MP3 format, or table of contents (TOC) data, if the recording is on a removable medium, such as a compact disc. At least one and preferably several algorithmically determined fingerprints are extracted from the recording using one or more fingerprint extraction methods. The information extracted is compared with corresponding information in a database maintained for reference recordings. Identification starts with the most accurate and efficient method available, e.g., using a hash ID, a unique ID or text. Fingerprint matching is used to confirm other matches and validation is performed by comparing the duration of the unknown and a possibly matching reference recording. | 06-24-2010 |

| 20100106807 | METHOD AND SYSTEM FOR ACCESSING WEB PAGES BASED ON PLAYBACK OF RECORDINGS - Entertainment content complementary to a musical recording is delivered to a user's computer by a computer network link. The user employs a browser to access the computer network. A plug-in for the browser is able to control an audio CD or other device for playing the musical recording. A script stored on the remote computer accessed over the network is downloaded. The script synchronizes the delivery of the complementary entertainment content with the play of the musical recording. | 04-29-2010 |
| 20100094897 | UNIFIED FORMAT FOR DIGITAL CONTENT METADATA - A method and system to provide a unified format for digital content metadata are described. The system may include a module to obtain source data associated with media content; a module to identify, based on the source data, the media content; an extractor to obtain metadata associated the identified content; and a converter to format the obtained metadata according to the popular music format. The popular music format is a tree field format, where the fields are to store the title of the album, the title of the track, and the name of the artist. | 04-15-2010 |
| 20100005104 | METHOD AND SYSTEM FOR MEDIA NAVIGATION - A method and system for media navigation. A descriptor hierarchy may be accessed. The descriptor hierarchy may include at least one category list. One or more media descriptors may be accessed for a plurality of media items. The plurality of media items may be accessible from a plurality of sources. The one or more media descriptors may be mapped to the at least one category list. The navigation may be processed through a user interface to enable selection of the plurality of media items from the plurality of sources. | 01-07-2010 |
| 20090158155 | PLAYLIST GENERATION, DELIVERY AND NAVIGATION - Automatic and assisted playlist generation is accomplished by collecting data from users of a world-wide music information system. Attributes of the recordings listened to by users are extracted from data collected when the users access the music information system. The attributes are correlated with other attributes in the system to verify data accuracy. Users can specify a set of attributes of their music collection for automatic generation of a playlist. The playlist can then be further edited, even on devices with a limited display and a few buttons designed for playback of recordings, by re-mapping the functions of the buttons for playlist generation. | 06-18-2009 |
| 20090076821 | METHOD AND APPARATUS TO CONTROL OPERATION OF A PLAYBACK DEVICE - Media metadata is accessible for a plurality of media items (See FIG. | 03-19-2009 |
| 20080263360 | Generating and matching hashes of multimedia content - Hashes are short summaries or signatures of data files which can be used to identify the file. Hashing multimedia content (audio, video, images) is difficult because the hash of original content and processed (e.g. compressed) content may differ significantly. The disclosed method generates robust hashes for multimedia content, for example, audio clips. The audio clip is divided ( | 10-23-2008 |
