DETERMINATION OF FILTRATION BOUNDARY LEVEL OF DEBLOCKING FOR VIDEO CODING Russian patent published in 2016 - IPC H04N19/86 H04N19/80 H04N19/14 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Method of encoding video data comprises associating, without determining whether region between first video block and a second block of video edge coding units (CU), first value level border edge in response to determining that first block of video and second video block associated with internally predicted CU; associating a second value with level of boundary edge in response to determining that first video block and a second video block are not associated with predicted internal CU, and that first unit or second video block associated with a video transformation unit (TU) with non-zero transform coefficient levels; associating a second value or level range, or third boundary value level with edge when first block of video and second video block are not associated with predicted internal CU, and first block of video and second video block are not associated with level of TU with non-zero transform coefficient; use of one or more of deblocking filter to samples associated with edge, when said value associated with first or second level of border level value of border, but not value of third level of border.

EFFECT: technical result is reducing appearance of visual artifacts.
