摘要： A technique of reconstructing a high resolution image from at least one image sequence of temporally related high and low resolution image frames wherein each of said high resolution image frames includes a low spatial frequency component and a high spatial frequency component is described. The high-resolution image reconstruction technique uses spatial interpolation to generate a low spatial frequency component from a low-resolution image frame of the image sequence. The technique is adapted to generate a high spatial frequency component from at least one high resolution image frame of the image sequence which is closely related to the low resolution image frame, and to remap the high spatial frequency component to a motion-compensated high spatial frequency component estimate of the low resolution image frame. The motion-compensated high spatial frequency component estimate is added to the generated low spatial frequency component to form a reconstructed high-resolution image of the low-resolution image frame.

摘要： In one aspect, audio summaries and transition audio segments are sequentially rendered with at least one transition audio segment rendered between each pair of sequential audio summaries. Each audio summary comprises digital content summarizing at least a portion of a respective associated audio piece. In another aspect, an original audio file is annotated by embedding therein information enabling rendering of at least one audio summary contained in the annotated audio file and comprising digital content summarizing at least a portion of the original audio file. In another aspect, an original audio file is annotated by providing at least one browsable link between the original audio file and at least one audio summary comprising digital content summarizing at least a portion of the original audio file, and storing the original audio file, the at least one browsable link, and the at least one audio summary on a common portable storage medium. In another aspect, an audio piece is divided into audio segments. Acoustical features are extracted from each audio segment. Audio segments are grouped into clusters based on the extracted features. A representative audio segment is identified in each cluster. A representative audio segment is selected as an audio summary of the audio piece.

摘要： Methods, computer-readable media, and systems are provided for combining multiple video streams. One method for combining the multiple video streams includes extracting a sequence of media frames (224-1/224-2) from presenter (222-1) video and from shared digital rich media (222-2) video (340). The media frame (224-1/224-2) content is analyzed (226) to determine a set of space and time varying alpha values (228/342). A compositing operation (230) is performed to produce the combined video frames (232) based on the content analysis (226/344).

摘要： Methods and systems that reduce video crosstalk in video streams sent between participants in a video conference are disclosed. In one aspect, a method for reducing video crosstalk in a video stream sent from a local site to a remote site includes projecting a video stream of the remote site onto a screen at the local site. Each image in the video stream is dimmed according to a dimming factor of a dimming sequence. Crosstalk images of the local site are captured through the screen. Each crosstalk image is a blending of the image of the local site captured through the screen with a dimmed image of the remote site projected onto the screen. Images of the local site with reduced crosstalk are computed based on the dimming sequence. A video stream composed of the images of the local site with reduced crosstalk are sent to the remote site.

摘要： Methods and systems for using portable electronic devices in video conferences are disclosed. In one aspect, a method receives each remote participant's audio data stream and at least one video stream over a network and arranges the video streams in a data structure that describes the location of each video stream's associated viewing area within a virtual meeting space. The method blends audio streams into a combined audio of the remote participants. The method presents at least one viewing area on the portable device display to be viewed by the local participant, and changes the at least one viewing area to be presented on the portable device display based on cues provided by the operator.
