FIELD: information technologies.
SUBSTANCE: fragments may be aligned with cycle so that beginning of working data of each of fragments practically matches beginning of one of cycles. Certain cycles may be controlled with the help of vector mode to scan for previously determined position within the framework of block prior to displacement to another block. Therefore, number of cycles may be reduced, cutting number of fragments and associatively related volume of service information. CAF may be entropically coded independently on each other, so that each of fragments could be easily accessible and decoded without waiting for decoding of other fragments, which provides for parallel decoding and simultaneous processing of these fragments.
EFFECT: increased efficiency of video coding based on cycles, coding of coefficients of blocks of FGS-video data and syntactic elements, reduction of fragments number and volume of service information.
