    Abstract: Procedimiento para crear una imagen de presencia continua (CP) objetivo codificada según una norma de codificación de vídeo a partir de una pluralidad de señales de vídeo codificadas incluyendo órdenes definidos de macrobloques, comprendiendo cada uno señales de vídeo codificadas correspondientes a una imagen de vídeo respectiva de terminal final recibida desde terminales finales que participan en una conferencia de vídeo multipunto, caracterizado por el hecho de que el procedimiento comprende las siguientes etapas: - descodificar dichas señales de vídeo codificadas, dando como resultado imágenes de vídeo de terminal final, - mezclar espacialmente dichas imágenes de vídeo de terminal final, dando como resultado una pluralidad de imágenes CP compuestas por regiones asociadas respectivamente con cada una de dichas imágenes de vídeo de terminal final, - codificar dichas imágenes CP, - reorganizar los macrobloques de las imágenes CP codificadas, creando de ese modo dicha imagen CP codificada objetivo.

    Abstract: The present invention utilizes video compression techniques in providing multi display and user control of picture layout with a single non-mechanical camera. According to a preferred embodiment of the present invention, a subsection of interest within a general view captured by the camera is coded based on the prediction of the main picture. In one aspect of the embodiment, scaling of the predicted pixel values in the subsection to match with the corresponding raw pixel data of extended resolution is carried out before subtracting the prediction from the raw data to provide the residual in the coding process. In a second aspect, the frame rate and the number of quantization intervals are increased when coding the subsection relative to the coding of the general view.

    Abstract: THE present invention discloses a system and method for automatically detecting the presence of a user in a presence application connected to a video conference endpoint. The presence detection is provided by active detection mechanisms monitoring the localities near the endpoint or terminal connected to the application. The presence information is centrally stores in a presence server collecting the information directly from the respective user terminals. According to preferred embodiments of the present invention, presence is determined by means of radar detection, infrared light detection, motion search in the video processing to the codec in the and face detection/recognition.

    Abstract: An arrangement and a method of localizing active speakers in a video conference includes a localization device that locates at least one microphone relative to the camera, while the at least one microphone in turn localizes the relative positions of audio sources. As the microphones are usually positioned close to the audio source in a video conference, the ratio of the distance between microphones relative to the distance between table microphone and audio source is reduced. Thus, the microphones are able to determine the positions of the audio sources with a higher resolution than if placed close to the camera. When the respective positions of the microphones relative to the camera and the audio source are known, the position of the audio source relative to the camera is then determined by means of geometrical calculations.
