摘要： A sequence of digital images is encoded into a plurality of encoding units. An image portion is encoded by motion compensation with respect to a reference image portion indicated by an item of motion information. A motion information predictor is determined among a set of motion information predictors and the item of motion information is encoded with respect to the motion information predictor. It is determined to encode the motion information predictors of an encoding unit using either a first encoding mode, which provides encoded data efficiently compressed but not parseable by a decoder in case of losses in the bitstream, or a second encoding mode which provides encoded data less efficiently compressed but systematically parseable by a decoder even in case of losses in the bitstream.

摘要： Video encoding and decoding with low complexity A target number (Nmax) of motion information predictors to be used for an image portion to encode is obtained. A first set of motion information predictors is obtained (S500) each associated with an image portion having a predetermined spatial and/or temporal relationship with the image portion being encoded.

摘要： A video signal has at least a first signal component corresponding to a first color, and a second signal component, associated with the first signal component and corresponding to a second color. Each signal component is divided into blocks, and each block has one or more encodable units. The encoding of at least one encodable unit of the second signal component is switchable between first and second modes. A method of encoding the signal comprises excluding,for at least one encodable unit of the second signal component, use of the second mode for the encoding of the second- signal-component encodable unit concerned when at least one predetermined condition is satisfied relating to an encoded block or encodable unit of the first signal component that corresponds to the second-signal-component encodable unit concerned.

摘要： For an image portion to encode an initial set of motion information predictors is obtained (S502). It is tested (S512) whether the number (N) of motion information predictors in the initial set is lower than a target number (Nmax) and, if so, one or more motion information predictors are added(S516) to the initial set to generate a set of motion information predictors having controlled diversity. The motion information predictors of the initial set are actual motion information predictors, having motion vectors obtained from image portions of the image being encoded or of a reference image, and potential motion information predictors for addition include one or more further such actual motion information predictors and also include one or more virtual motion information predictors not having motion vectors obtained from image portions of said image being encoded or of a reference image. A motion information predictor for the image portion to encode is selected from the generated set of motion information predictors.
