    • Interlaced video can be encoded in two layers, base layer and enhancement layer. A method for optimizing the encoding of motion vectors for enhancement layer is proposed. It comprises defining various different ways to encode the motion vectors, estimate the coding costs for each way, and select the way with the lowest coding cost. The various ways to encode enhancement layer motion vectors can be combined. Either motion vectors from base layer are reused, resulting in a scaling factor and an update vector, or new motion vectors are calculated. Either forward or backward or bi-directional prediction can be used. Either one frame or multiple frames can be taken as reference. The reference frame can be from the enhancement layer, base layer or both. Either the complete motion vectors are encoded, or only the difference between the motion vector and the corresponding BL motion vector is encoded.
    • 隔行视频可以编码在两层,基层和增强层中。 提出了一种优化增强层运动矢量编码的方法。 它包括定义各种不同的方式对运动矢量进行编码,估算每种方式的编码成本,并选择具有最低编码成本的方式。 编码增强层运动矢量的各种方式可以组合。 来自基层的运动矢量被重用,导致缩放因子和更新向量,或者计算新的运动矢量。 可以使用向前或向后或双向预测。 可以将一帧或多帧作为参考。 参考帧可以来自增强层,基本层或两者。 对整个运动矢量进行编码,或仅对运动矢量与对应的BL运动矢量之间的差进行编码。

    • The invention relates to a method for reconstructing a picture that is part of a sequence of pictures, from coded digital data, representative of said current picture. It comprises the following steps: - construct (30, 34, 32, 36), for each picture block, first and second prediction blocks (from a first picture (h) and a second picture (I2) previously reconstructed, and - calculate (38), for each block, a confidence value representative of the proximity between the visual content of the first predictive block and the visual content of the second predictive block, and - reconstruct each block: - from a part of said coded digital data representative of said block and initial auxiliary data calculated from the first and second predictive blocks if the block confidence measurement is greater than a predetermined threshold, and - from other data if the confidence measurement is less than or equal to the predefined threshold.
