    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: An orchestration server and a method of deploying a distributed videoconferencing system in cloud services are disclosed. The method comprises receiving, by an orchestration server, a proposed configuration of a distributed videoconferencing system, determining, by the orchestration server, a status of the proposed configuration of the distributed videoconferencing system, determining, by the orchestration server, based on the status of the proposed configuration of the distributed videoconferencing system, a determined configuration of the distributed videoconferencing system, initiating, by the orchestration server, according to the determined configuration of the distributed videoconferencing system at least one non-transcoding node at a first data center of a first cloud service provider, and initiating, by the orchestration server, according to the determined configuration of the distributed videoconferencing system at least one transcoding node at a second data center. Furthermore, a corresponding computer program and a carrier are disclosed.
