Abstract: Timeline (200) information is provided to endpoints in a video conferencing system. The timeline (200) comprises a starting time point (201), a current time point (203) and a plurality of timestamps (202) that represent respective points in time between the starting time point and the current time point. A plurality of events are detected that are associated with respective system generated activities or activities performed by participants located at the endpoints. Event information is provided, to at least one endpoint, for displaying along the timeline a respective graphical item (204) representing respective detected events. This providing of event information is performed repeatedly such that the graphical items slide along the timeline in a direction away from the current time point.

Abstract: A method to quickly determine whether a macroblock in H.264 or other similar standards should be encoded in skip mode in a SIMD processor environment is provided. The method exploits the fact that the processor provides enough register space to store N=4 4x4 set of 8 bits data. By performing 4 consecutive reads of 16 linear aligned values into 16 SIMD register variables each capable of storing 16 values, the entire data set for operating can be stored within the processors SIMD register variables and can be operated upon, without any memory related latency.

Abstract: A method of speech detection and speech enhancement in a speech detection and speech enhancement unit of Multipoint Conferencing Node (MCN) and a method of training the same. The method comprising receiving input audio segments, and determining an acoustic environment based on input audio auxiliary information, extracting T-F-domain features from the received input audio segments, determining if each of the received input audio segments is speech by inputting the T-F domain features into a speech detection classifier trained for the determined acoustic environment, determining, when one of the received input audio segments is speech, if the received audio segment is noisy speech by inputting the T-F domain features into a noise classifier using a statistical generative model representing the probability distributions of the T-F domain features of noisy speech trained for the determined acoustic environment, and applying a noise reduction mask on the received input audio segments according to the determination of the received audio segment is noisy speech

Abstract: The present invention relates to an image processing device and a method of framing changes and movements in a video image divided into N×N blocks of pixel positions. The method comprises calculating a first bitmap of the video image by a DCT transform on each of the N×N blocks of pixel positions, assigning a first binary value to the pixel positions of the N×N blocks when more than an amount of change, and a second binary value to the pixel positions of the N×N blocks when less than an amount of change. Calculating a third bitmap by an OR operation between a number of bitmaps representing past time frames of the video image, calculating a fourth bitmap by performing a dilation process of the third bitmap representing the current time frame of the video image, and creating one or more frames identifying area of changes and movements in the video image based on detecting BLOBs (Binary Large Objects) in the fourth bitmaps.
