Definitions
- the I-slice is a slice in which all macroblocks of the slice are coded using an intra-prediction.
- an encoder / D & encoder concept is achieved which, on the one hand, has the possibility of scalability and, on the other hand, can build on standard-compliant elements, in particular, for example, for motion compensation.
- a basic lifting scheme on the coder side or an inverse lifting scheme on the decoder side will first be described with reference to FIG. 3. Detailed explanations of the backgrounds of the combination of lifting schemes and wavelet transformations can be found in W. Sweldens, "A cuentom design construction of biorthogonal wavelets", J. Apjpl Comp. Harm. Anal., Vol (no.2), pp.
- the prediction step is equivalent to carrying out a high-pass filter of a two-channel filter bank, as described in I. Daiagbeies and W. Sweldens, "Factoring wavelet transforms im- lifting steps", J. Fourier Anal. Appl.vol 4 (no.3), pp. 247-269, 1998.
- low-pass filtering is performed by replacing the even samples 5 even [ ⁇ :] with a linear combination of the prediction residuals h [k].
- the corresponding updating operator U is given by
- the low-pass and the high-pass analysis filters of this wavelet have 5 resp. 3 filter taps, wherein the corresponding scaling function is a B-spline of order 2.
- this wavelet is used for a large subband coding scheme.
- the corresponding predictive and updating operators are the same. Transformation as follows
- MCTF motion, so it has been found that the above-described NEN ⁇ Skalierlessschemata, the compensated at the motion temporal filtering (MCTF Compensated Temporal Filtering) already provide a high degree of flexibility in terms of time scalability and SNR scalability.
- MCTF Compensated Temporal Filtering already provide a high degree of flexibility in terms of time scalability and SNR scalability.
- exis ⁇ cash discount is a problem in that the bit rate of several scaling layers still together significantly higher than the bit rate is the e can be achieved if pictures would be diert co ⁇ with the highest quality without scalability.
- scalable encoders may never reach the bit rate of the non-scaled case.
- the bit rate of a data stream with multiple scaling layers should be at least as close as possible to the bit rate of the non-scaled case.
- the scalability concept should provide a high degree of flexibility for all types of scalability, ie a high degree of flexibility both in terms of time as well as in terms of space and in terms of SNR.
- the basic transaction data may be used in the actual calculation of the expansion Movement Dehn, as they are subsequently used by the expansion motion compensator, are taken into account.
- autonomous calculation of extension movement data is therefore carried out in the sense of high flexibility, whereby these extension movement data calculated independently of the base movement data are used for encoder prediction on the coder side, while the base movement data are only for Purposes of calculating a
- the finally obtained low-pass image is associated with a particular image of the original sequence of images, and that also each high-pass image is associated with an image of the original sequence, with exactly the deviations of the original image of the sequence (a Motion compensation) from the selected basic picture of the sequence (which is fed in the lower branch of the analysis filter bank of FIG. 4). If each update parameter M O i, Mu, IM 2I and M 3 i equal
- the current macroblock is set to INTRA_BASE, which means that it is a macroblock3 ⁇ with a prediction from the base layer.
- INTRA_BASE which means that it is a macroblock3 ⁇ with a prediction from the base layer.
- the same reference indices are used as for the corresponding macroblock / sub-macroblock partitionings of the base layer block.
- the associated motion vectors are multiplied by a factor of 2. This factor applies to the situation shown in FIG. 6b, in which a base layer 1102 comprises half the area or number in pixels As the extension layer 1104. If the ratio of the spatial resolution of the base layer to the spatial resolution of the extension layer is not equal to 3_ / 2, then corresponding scaling factors are used for the motion vectors.

Abstract
Selon l'invention, lors du codage vidéo modulable effectué en association avec une compensation de mouvement (1006, 1014), une prédiction (1014, 1016) des données de mouvement de la couche d'extension (1004) intervient aussi bien dans la couche de base (1002) que dans la couche d'extension, au moyen des données de mouvement de la couche de base (1004), afin d'obtenir un concept de modulabilité permettant d'une part de parvenir à une flexibilité maximale pour le calcul des données de mouvement des différentes couches et d'autre part, à un débit binaire réduit.
