In one embodiment, the invention is a method and apparatus for annotating media streams. One embodiment of a method for facilitating creation of an annotated media stream by a user includes receiving the media stream from the user, mapping at least one item of supplemental content to at least a portion of the media stream to produce the annotated media stream, and storing the annotated media stream. In another embodiment, a method for distributing an annotated media stream provided by a user includes receiving the annotated media stream from the user, where the annotated media stream includes at least one item of supplemental content mapped to at least a portion of a media stream to produce the annotated media stream, storing the annotated media stream, receiving a request from a viewer to view the annotated media stream, and distributing the annotated media stream to the viewer. In another embodiment, a method for distributing an annotated media stream provided by a user includes distributing the annotated media stream to a viewer, where the annotated media stream includes at least one item of supplemental content mapped to at least a portion of a media stream to produce the annotated media stream, and collecting a commission when the annotated media stream is viewed by the viewer. In one embodiment, the collecting requires further action on a part of the viewer (such as selection of a hyperlink contained in the at least one item of supplemental content or consummation of a commercial transaction).

A method for recognizing an audio sample locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample. The method can be used for any type of sound or music, and is particularly effective for audio signals subject to linear and nonlinear distortion such as background noise, compression artifacts, or transmission dropouts. The sample can be identified in a time proportional to the logarithm of the number of entries in the database; given sufficient computational power, recognition can be performed in nearly real time as the sound is being sampled.

In a digital television recording method, programs are selected for recording based on analysis of program schedule information, user preferences, and the priority of previously recorded programs if there is insufficient memory.

A method and system is described which allows users to identify (pre-recorded) sounds such as music, radio broadcast, commercials, and other audio signals in almost any environment. The audio signal (or sound) must be a recording represented in a database of recordings. The service can quickly identify the signal from just a few seconds of excerption, while tolerating high noise and distortion. Once the signal is identified to the user, the user may perform transactions interactively in real-time or offline using the identification information.

A system for handling data and transactions involving data through the use of a virtual transaction zone, which virtual transaction zone removes the dependency of such transaction on the delivery medium of the product.

The transaction zone also provides a mechanism for combining mediums, data feeds, and manipulation of those feeds. The transaction zone also provides a mechanism for controlling the content, delivery, and timing of delivery of the end consumer's product.

A method for delivery and presentation of content-relevant information associated with frames in an AV program enables TV viewers to retrieve information on the contents (for example, objects, items, concepts and the like) associated with a frame or a set of frames (video segments) when they watch TV or video programs. The information relevant to frame(s) is delivered to a STB or DVR by third-party service providers through back channels such as the Internet if the information of how to accurately access the frames pointed by STB users are delivered to the service providers, and the content-relevant information may be presented in the form of a GUI for the TV viewer.

A technique for automated analysis of multimedia, such as, for example, a news broadcast. A Broadcast News Editor and Broadcast News Navigator system analyze, select, condense, and then present news summaries. The system enables not only viewing a hierarchical table of contents of the news, but also summaries tailored to individual needs. This is accomplished through story segmentation and proper name extraction which enables the use of common information retrieval methodologies, such as Web browsers. Robust segmentation processing is provided using multistream analysis on imagery, audio, and closed captioned stream cue events.

The invention allows for a first set of persons to create and modify templates that contain visual effects, synchronization information, and possibly director assistance. These templates are utilized by a second set of persons to generate personalized motion photo videos from photographs, video segments, personal narratives or animation. Motion photo videos are a novel because they very quickly and inexpensively allow (1) persons to create and modify templates which are synchronized to music and may be easily populated with content by others, and (2) persons to select a song and associated pre-made template and create a high-quality synchronized custom video using hand-selected visual material to populate the template with included direction and without any required editing. Populated material in template can be further modified by additional persons instantly generate new, modified motion photo videos.

Improved techniques for automatic (or dynamic) updating (or maintaining) of playlists for a media system that stores and plays media content for a user of the media system. The automatic update to playlists can occur when additional media content is added to or removed from the media system. The automatic update to playlists can also occur when previously stored media content is otherwise altered.

An improved image tagging system that tags images in a mobile handheld communications device, based on the user's contacts list stored therein. The image tagging system compares a face in a given picture (that the user has just taken using the built-in camera) to faces in the user's contacts list images. A matching contact is found in the contacts list. The picture is then tagged with information from the matching contact. The picture is tagged by inserting identification information into a header of the picture.

A multimedia program bookmarking system provides a bookmark function that allows the user to bookmark a program where he left off. The invention records the frame of the program where the user stopped when the user commands the system to do so. Alternatively, the invention automatically bookmarks the program for the user if the user exits viewing the program. The invention displays an indicator indicating that a bookmark has been saved and the user can, at any time, access his bookmark and continue playback of the program from where he left off. Bookmarks within a single program can be set for different users. Remote controls are encoded for a specific user in a household, allowing each person in the household to have a personal remote control and therefore, personal bookmarks. The invention notes that a set of bookmarks belongs to a certain encoded remote control. The user can alternatively select a specific set of bookmarks manually, through a menu. The system loads the associated bookmark information for the user and any bookmarks that do not have associated programs stored on the storage device are ignored and deleted, otherwise programs are played backed starting from the associated bookmarks, if they exist. Multiple bookmarks for a program are transparent to the user because the remote control that the user uses tells the system to only display and activate that particular user's bookmarks.

A playback apparatus not only plays back an AV stream recorded on a BD-ROM but also downloads an update kit from a WWW server (500) and writes it on a local HD (12). The AV stream stored in the local HD (12) includes an audio stream for an additional language. A control unit (16) reads the AV stream recorded on the BD-ROM and the AV stream recorded in the local HD (12) in units of access units. An audio decoder (6) obtains a necessary audio frame from the access units read from the BD-ROM and the local HD (12) and plays it back. A video decoder (4) obtains video data from the access unit read from the BD-ROM and plays it back.

Grouping and navigating media files within a playlist on a computer-readable medium. Invention software selects media files according to a grouping criterion to define a group from the media files.

The invention software stores the selected media files, the playlist, the defined groups, and the associated group headers on a computer-readable medium. The invention software also includes playback software for navigating and selecting media files via groups within a playlist. In one embodiment, the invention is operable as part of a compressed media format having a set of small files containing metadata, menus, and playlists in a compiled binary formal designed for playback on feature-rich personal computer media players as well as low cost media players.

Methods, devices, systems and tools are presented that allow the summarization of text, audio, and audiovisual presentations, such as movies, into less lengthy forms. High-content media files are shortened in a manner that preserves important details, by splitting the files into segments, rating the segments, and reassembling preferred segments into a final abridged piece. Summarization of media can be customized by user selection of criteria, and opens new possibilities for delivering entertainment, news, and information in the form of dense, information-rich content that can be viewed by means of broadcast or cable distribution, “on-demand” distribution, internet and cell phone digital video streaming, or can be downloaded onto an iPod™ and other portable video playback devices.

If, in encoding and recording an AV stream, time_controlled_flag as the attribute information is set to 1, the relation between the time lapse of an AV stream and the amount of data bytes of the AV stream is linear within a preset error range. If the time_controlled_flag of the AV stream file is set to 1, and a certain time portion of the stream is erased by way of partial stream erasure, an unoccupied area corresponding to the erased time portion and which can be recorded at a bitrate indicated by TS_average_rate may be created on the disc.

A method of processing audio signals recorded during display of image data from a media file on a display device to produce semantic understanding data and associating such data with the original media file, includes: separating a desired audio signal from the aggregate mixture of audio signals; analyzing the separated signal for purposes of gaining semantic understanding; and associating the semantic information obtained from the audio signals recorded during image display with the original media file.

A method of annotating video programs (media) with metadata, and making the metadata available for download on a P2P network. Program annotators will analyze a video media and construct annotator index descriptors or signatures descriptive of the video media as a whole, annotator scenes of interest, and annotator items of interest. This will serve as an index to annotator metadata associated with specific scenes and items of interest. Viewers of these video medias on processor equipped, network capable, video devices will select scenes and items of interest as well, and the video devices will construct user indexes also descriptive of the video media, scenes and areas of interest. This user index will be sent over the P2P network to annotation nodes, and will be used as a search tool to find the appropriate index linked metadata. This will be sent back to the user video device over the P2P network.

For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer 104. The image data and sound data are stored in a buffer 105. Image data is read from the buffer 105 in accordance with a scenario and expanded to a graphics plane 133. In addition, corresponding sound data is read from the buffer 105 and reproduced by a sound player 106D. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.

A video retrieval system is presented that allows a user to quickly and easily select and receive stories of interest from a video stream. The video retrieval system classifies stories and delivers samples of selected stories that match each user's current preference. The user's preferences may include particular broadcast networks, persons, story topics, keywords, and the like. Key frames of each selected story are sequentially displayed; when the user views a frame of interest, the user selects the story that is associated with the key frame for more detailed viewing. This invention is particularly well suited for targeted news retrieval. In a preferred embodiment, news stories are stored, and the selection of a news story for detailed viewing based on the associated key frames effects a playback of the selected news story. The principles of this invention also allows a user to effect a directed search of other types of broadcasts as well. For example, the user may initiate an automated scan that presents samples of broadcasts that conform to the user's current preferences, akin to directed channel-surfing.

An interested party is afforded a high level of access to many data types in highly graphical and intuitive arrangements. Further, data replay access is enhanced by slow motion, fast forward, loop repeat, among others which have never before been associated with these data types nor with the compound visual presentations first taught in the accompanying disclosure.

An audio fingerprint is extracted from an audio sample, where the fingerprint contains information that is characteristic of the content in the sample. The fingerprint may be generated by computing an energy spectrum for the audio sample, resampling the energy spectrum logarithmically in the time dimension, transforming the resampled energy spectrum to produce a series of feature vectors, and computing the fingerprint using differential coding of the feature vectors. The generated fingerprint can be compared to a set of reference fingerprints in a database to identify the original audio content.
