摘要： The invention relates to a method of coding an input digital video sequence corresponding to an original color image sequence, said method comprising at least a step for converting said video sequence from the spatial domain to less representation data, a quantization step, for transforming the converted signals thus obtained into a reduced set of data. According to the invention, said coding method also comprises, before said converting step, a pre-processing step, provided for determining if the input video sequence is in YUV color space, Y being the luminance component and U, V the chrominance components, and transforming said space into a less redundant color space by means of a non-linear transformation taking into account the possible lower quality finally obtained.

摘要： A method for selection of shots represented by identifiers displayed in a navigation menu. A document is divided into shots. Several attributes such as the moment of appearance of the shot in the document are assigned to each shot. The navigation menu disposes the identifiers according to a first axis according to the moment of appearance of the associated shot and according to a second axis according to the value of a second attribute according to a criterion other than the moment of appearance. A third attribute is determined for each shot according to a criterion other than the two first criteria, the shot identifiers having the same value as this third attribute are connected graphically. In this way the user perceives the value of several attributes associated with each shot and can easily select the shot that interests him. A display device able to display the navigation menu.

摘要： Fully scalable encoder and decoder for interlaced video. A method for encoding an interlaced sequence of digital video data decomposes the interlaced video sequence into first and second fields, performs digital filtering to get lower frequency and higher frequency component signals of the first fields, and uses spatio-temporal filtering and motion estimation for generating base layer signals being suitable for reconstruction of a progressive mode video sequence in a receiver. Advantageously, both the spatio-temporal filter at the encoder, and the inverse process at the receiver, can perform scaling in spatial and temporal dimension. The second fields are used to generate enhancement signals, which enable a receiver to reproduce an interlaced video sequence of the full, or scaled, spatial and/or temporal resolution.

摘要： 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.

摘要： The invention relates to a video coding method and device applied to a sequence of frames and generating a coded bitstream in which each data item is described by means of a bitstream syntax allowing any decoder to recognize and decode all the elements of the content of said bitstream. According to the invention, which finds an application for instance within the video compression standard MPEG-4, the syntax comprises a specific one bit flag provided for indicating at a high level description the presence, or not, of a shape for each video object of the scenes of the sequence. This flag is transmitted in the coded bitstream, and its value is read at the decoding side for controlling correspondingly the decoding step.

摘要： The method realizes a motion compensated temporal filtering (MCTF), the temporal filtering being replaced by an intra mode coding to obtain at least one low (L) or high (H) frequency picture if the current picture has a level of correlation with a lower previous picture at a threshold, the low frequency pictures obtained (L) being thus scaled to be adapted, at the energy level, to the pictures obtained by motion compensated temporal filtering, and comprises, at the end of analysis: a selection of the pictures obtained by intra coding of a picture of a low decomposition level with the additional condition, for the high frequency pictures, that this picture is derived itself from an intra coding. a calibration of the picture selected by carrying out at least one reverse step of the scaling step. The applications relate to video compression with temporal prediction.

摘要： In video encoding, the video frames are spatio-temporally filtered for reduction of spatial and temporal redundancy before they are entropy encoded. Known filtering schemes consider temporally successive frames and are static. It is probable but not necessary that successive frames are most efficient to encode. Therefore, a plurality or all possible frame order permutations are considered for a group of frames (GOP) and evaluated based on a global criterion, which is the sum of local criterion values computed over successive subsets of permuted frames. The local criterion value is deduced from motion estimation processed on each considered set of frames. The best ordering is chosen as the one that minimizes the global criterion value.
摘要翻译：在视频编码中，对视频帧进行时空滤波，以便在熵编码之前减少空间和时间冗余。已知的滤波方案考虑时间上连续的帧，并且是静态的。连续的帧是编码最有效的可能但不是必需的。因此，对于一组帧（GOP）考虑多个或所有可能的帧顺序排列，并且基于全局准则来评估，该全局标准是在连续的置换帧的子集上计算的局部标准值的总和。从每个考虑的帧集合处理的运动估计推导出局部标准值。选择最佳顺序作为最小化全局准则值的顺序。
