Abstract: The present invention creates compositions of pictures in multipoint conferences that emulate natural interaction and existing aesthetic sensibilities learned from visual media by a combination of correcting and adapting the composition of the picture content and the layout, preferably in the MCN of the conference, where real-time conference data is available, in addition to statistics and knowledge of historical conference data. Further, cross checking incoming imagery against a ruleset where compositional deltas are identified is done, and these corrective transformations are applied, and the resulting corrections and remixes are applied to the layout. More advanced transformations to the final composition based on presence and context define a layout. The ruleset could be both static and dynamic, or a combination, and the final recomposition of the layout may be a result of both corrective and adaptive transformations.

Abstract: A method and a decoding or coding device for calculating at least one of run and level representations of respective quantized transform coefficients representing pixel values in a block of a video picture inserted in a coefficient array is disclosed. The method and the decoding or coding device are adjusted to generate a bitmask of the quantized transform coefficients, respectively perform a look up of the 8 least significant bits and the 8 most significant bits of the bitmask in a look up table, patch the looked up lower part and upper part bytemap values and insert the bytes of the first bytemap array from index position 8 minus the number of non-zeros in the 8 least significant bits of the bitmask.

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.
