摘要： 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.

摘要： 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.

摘要： The present invention relates to generating Continuous Presence (CP) images in a Multipoint Control Unit (MCU) managing a multisite videoconference. The invention utilises the bit structure of the ITU H.26* standards to reduce the processing time and requirements in an MCU for generating CP views without self-view. By rearranging macroblocks from coded CP images, regions in a CP image may be removed so as allow transmitting CP images without self view to the participating sites. The rearranging procedure significantly reduces the requirement of encoder resources in an MCU.

摘要： A unified solution to coding/decoding of different video formats such as 4:2:0, 4:2:2 and 4:4:4 is provided. A method of video coding includes transforming a first m×n macro block of residual chrominance pixel values of moving pictures by a first integer-transform function generating a corresponding second m×n macro block of integer-transform coefficients, further transforming DC values of the integer-transform coefficients by a second integer-transform function to generate a third block of integer-transformed DC coefficients. The method further includes generating the second m×n macro block of integer-transform coefficients by utilizing a k×k integer-transform function on each k×k sub-block of the first m×n macro block, wherein n and m are each a multiple of k, and generating the third block of coefficients by utilizing a second i×j integer-transform function on the DC values resulting in a (m/k)×(n/k) third block of integer-transformed DC coefficients.
