FIELD: information technologies.
SUBSTANCE: several various VLC-tables are stored in coding devices, in process of coding and decoding, one of VLC-tables is selected and used to do coding of SVR for this video unit. Table may be selected on the basis of number of neighbouring video units for current video unit, which include non-zero transformation ratios.
EFFECT: increased coefficients of coding of SVR video units, in which structures of coefficients occurring with higher probability, are coded with the help of shorter codes, while structures of coefficients, which occur with lower probability, are coded with the help of longer codes, which is especially useful in coding of video units of improved layers in coding of scalable video.
