摘要： The invention concerns a method and a device for inserting 3D graphic animation in a 3D image, each 3D graphic element of the graphic animation being defined in size and in depth for the insertion in a determined insertion zone of said 3D image. The method comprises the step of determining for the graphic element to be inserted a depth range with a maximum allowed depth value;, replacing the out of range depth values by the maximum allowed depth value when depth values of the graphic element are out of range and compensating the depth difference between the depth values of the graphic element and the maximal allowed depth value in reducing the graphic element in size proportionally to the reduction of depth for the graphic element.

摘要： The invention relates to a process for coding images transmitted according to the so-called multiresolution technique. According to this process, a step of pixel level processing of so-called mixed blocks of pixels, that is to say those shared between at least one zone of a first resolution and at least one zone of a second resolution, is performed.
A block is thus transmitted, the pixels of whose zone of the first resolution are assigned this first resolution and the pixels of whose zone of second resolution are assigned this second resolution.

摘要： The invention relates to a method for insertion of data in a block of image data, called the current block, of a sequence of images. The current block is coded or intended to be coded in the form of temporally predicted image data from prediction image data defined according to a first prediction mode According to the invention, the insertion method comprises the modification, according to the data to be inserted, of the first prediction mode into a second prediction mode different from the first prediction mode with a view to coding of the current block according to the second prediction mode, the second prediction mode being defined so that the prediction image data obtained with the second prediction mode are identical to the prediction image data obtained with the first prediction mode.

摘要： The objective of the invention is to improve the performance of a transrating system (10). A processed video stream (IN) may contain at least one slice of a picture, the slice comprising luminance coefficients (Y) and chrominance coefficients (U, V). According to a first inventive method, the slice is transrated by performing at least a part of both a decoding procedure and an encoding procedure on that slice. For this, at least two independent transrating-units (14, 16, 18) are provided, each of which is designed to perform the decoding-encoding procedure independently from the other transrating-units (14, 16, 18). One of the transrating-units (14) processes the luminance data (Y), while at least one other of the transrating-units (16, 18) processes the chrominance data (U, V). According to a second inventive method, the two types of coefficients (Y and U, V) are re-quantised such that a different change in quantisation level results.
