Streaming latency in an internet protocol television (IPTV) system is decreased by providing a separate source of the selected A/V content to the user that is immediately available to the user when the user requests the A/V content, and that can be used until the requested A/V content is received from the service provider. The separate source can be a channel change stream (CCS) channel broadcast or multicast from the service provider to the user or a local user storage containing stored initial segments of the A/V content.

A system and associated method automatically discover salient segments in a speech transcript and focus on the segmentation of an audio/video source into topically cohesive segments based on Automatic Speech Recognition (ASR) transcriptions. The word n-grams are extracted from the speech transcript using a three-phase segmentation algorithm based on the following sequence or combination of boundary-based and content-based methods: a boundary-based method; a rate of arrival of feature method; and a content-based method. In the first two segmentation passes, the temporal proximity and the rate of arrival of features are analyzed to compute an initial segmentation. In the third segmentation pass, changes in the set of content-bearing words used by adjacent segments are detected, to validate the initial segments for merging them, to prevent over-segmentation.

A method of analyzing a symbol comprised of one or more drawn strokes is comprised of calculating the speed of drawing along each stroke. A curvature magnitude along each stroke is calculated. An initial set of candidate points defining initial segments is identified using the calculated speed and curvature metric magnitude. The initial segments are classified as a type of primitive. The initial segments are compared to the original stroke. Merging and splitting of certain of the initial segments may be performed in response to the comparison to produce new segments which are classified as a type of primitive. Because of the rules governing abstracts, this abstract should not be used in construing the claims.
