Entropy coding of the current part of a predetermined entropy slice is based not only on corresponding estimates of probability of predetermined entropy slice, which adapt using previously encoded part of the predetermined entropy slice, but also on the estimates of probability, which are used at entropy coding of spatially adjacent, by the order number of entropy slices, previous entropy slice in its adjacent part. Therethrough, the estimations of probability used at entropy coding are adapted to actual statistical information of a symbol more closely, thus reducing the coding efficiency reduction usually caused by concepts of lower delay. Time correlations are used additionally or alternatively.EFFECT: possibility of reducing delay when coding arrays of samples.21 cl, 20 dwg, 4 tbl
High-precision upsampling with scalable coding of video images with high bit depth // 2610589
FIELD: computer engineering.SUBSTANCE: invention relates to computer engineering. In a scalable video system method of upsampling image data from a first level to a second level includes determination of parameters of scaling and rounding-off in response to requirements of scalable video system to bit depth. Input data are first filtered according to a first spatial direction using a first parameter of rounding in order to generate first upsampled data. By scaling first upsampled data using a first shift parameter, first intermediate data are generated, which are then filtered according to a second spatial direction using a second parameter of rounding in order to generate second upsampled data. Then by scaling second upsampled data using second shift parameter, second intermediate data are generated. Final upsampled data can be generated by cutting off second intermediate data.EFFECT: technical result consists in maintaining accuracy of upsampling operations.13 cl, 3 dwg
