Abstract:

The present invention provides for a method and apparatus for segmenting a multi-media program based upon audio events. In an embodiment a method of classifying an audio stream is provided. This method includes receiving an audio stream. Sampling the audio stream at a predetermined rate and then combining a predetermined number of samples into a clip. A plurality of features are then determined for the clip and are analyzed using a linear approximation algorithm. The clip is then characterized based upon the results of the analysis conducted with the linear approximation algorithm.

International Classification:

H04N 9/47

US Classification:

348445, 84600

Abstract:

Disclosed herein are systems, methods, and computer readable-media for adaptive content rendition, the method comprising receiving media content for playback to a user, adapting the media content for playback on a first device in the user's first location, receiving a notification when the user changes to a second location, adapting the media content for playback on a second device in the second location, and transitioning media content playback from the first device to second device. One aspect conserves energy by optionally turning off the first device after transitioning to the second device. Another aspect includes playback devices that are “dumb devices” which receive media content already prepared for playback, “smart devices” which receive media content in a less than ready form and prepare the media content for playback, or hybrid smart and dumb devices. A single device may be substituted by a plurality of devices. Adapting the media content for playback is based on a user profile storing user preferences and/or usage history in one aspect.

US Classification:

707736, 707756, 707796, 707E17114

Abstract:

Disclosed herein are systems, methods, and computer-readable media for transmedia video bookmarks, the method comprising receiving a first place marker and a second place marker for a segment of video media, extracting metadata from the video media between the first and second place markers, normalizing the extracted metadata, storing the normalized metadata, first place marker, and second place marker as a video bookmark, and retrieving the media represented by the video bookmark upon request from a user. One aspect further aggregates video bookmarks from multiple sources and refines the first place marker and second place marker based on the aggregated video bookmarks. Metadata can be extracted by analyzing text or audio annotations. Another aspect of normalizing the extracted metadata includes generating a video thumbnail representing the video media between the first place marker and the second place marker. Multiple video bookmarks may be searchable by metadata or by the video thumbnail visually.
