SEPARATELY CODING POSITION OF LAST SIGNIFICANT COEFFICIENT OF VIDEO BLOCK IN VIDEO CODING Russian patent published in 2015 - IPC H04N19/18 H04N19/13 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method of coding coefficients associated with a block of video data during a video coding process, the method comprising coding information that identifies a position of a last non-zero coefficient within the block according to a scanning order prior to coding information that identifies positions of other non-zero coefficients within the block, wherein coding the information that identifies the position of the last non-zero coefficient includes coding a two-dimensional position within the block that identifies the position of the last non-zero coefficient within the block according to the scanning order by determining a horizontal coordinate and a vertical coordinate of the position of the last non-zero coefficient within the block according to the scanning order and converting into binary form the horizontal and vertical coordinates such that the horizontal coordinate comprises a first and the vertical coordinate comprises a second sequence of one or more sampling elements; and coding the first and second sequences of the one or more sampling elements by performing a context adaptive binary coding process.

EFFECT: high coding efficiency.
