摘要： A method, an apparatus, and a storage medium with executable code to execute a method including accepting camera views of at least some participants of a teleconference, each view from a corresponding video camera, with the camera views together including at least one view of each participant. The method includes accepting audio from a plurality of microphones, and processing the audio from the plurality of microphones to generate audio data and direction information indicative of the direction of sound received at the microphones. The method further includes generating one or more candidate people views, with each people view being of an area enclosing a head and shoulders view of at least one participant. The method also includes making a selection, according to the direction information, of which at least one of the candidate people views are to be transmitted to one or more remote endpoints.

摘要： A system and method for creating a virtual round table videoconference is described. An embodiment of the system comprises a plurality of displays arranged in an configuration with a table to create a virtual round table. Cameras are arranged around the plurality of displays such that when a participant looks at a display with a image of a remote participant, the camera associated with the display captures an image of the participant's gaze, making eye contact with the camera. The image is displayed at the remote participant's endpoint creating the effect of eye contact between the participants. In another embodiment, audio speakers are arranged to provide directional sound that the video source for a display and the audio source for the associated speaker are from the same endpoint.

摘要： Particular embodiments generally relate to video compression. In one embodiment, a store of reference frames is provided in memory. The reference frames may be classified based on a plurality of classifiers. The classifiers may correspond to features that are found in the reference frame. A frame to encode is then received. The frame is analyzed to determine features found in the frame. As macroblocks in the frame are encoded, a macroblock is analyzed to determine which feature may be included in the macroblock. The feature is used to determine a classifier, which is used to determine a subset of the reference frames. The subset is then searched to determine a reference frame for the macroblock.

摘要： An apparatus, a method, and a computer-readable medium having instructions encoded thereon that when executed cause a method to be carried out. The method includes dividing at least a portion of a picture of a video stream into parts of blocks, and processing the parts in parallel by a plurality of interconnected processors. The processing of a respective part by its respective processor includes determining block- features, e.g., block level temporal features and/or block level edge features. Each processor also performs coding functions on its respective part of the picture. The method also includes block-level processing using the block-level features to determine which blocks in the picture are likely to be that of a face, the block-level processing being at the granularity of at least a block.

摘要： A method and system is described for video encoding with multiple parallel encoders. The system uses multiple encoders which operate in different rows of the same slice of the same video frame. Data dependencies between frames, rows, and blocks are resolved through the use of a data network. Block information is passed between encoders of adjacent rows. The system can achieve low latency compared to other parallel approaches.

摘要： Techniques are provided for establishing a videoconference session between participants at different endpoints, where each endpoint includes at least one computing device and one or more displays. A plurality of video streams is received at an endpoint, and each video stream is classified as at least one of a people view and a data view. The classified views are analyzed to determine one or more regions of interest for each of the classified views, where at least one region of interest has a size smaller than a size of the classified view. Synthesized views of at least some of the video streams are generated, wherein the synthesized views include at least one view including a region of interest, and views including the synthesized views are rendered at one or more displays of an endpoint device.
