Method for constructing tile structure and apparatus therefor
The present invention discloses a method for constructing a tile structure, wherein a current picture includes at least two or more tiles, the at least two or more tiles are split by a column splitting and a row splitting, at least one or more of the column splitting and the row splitting are performed by using a splitting length which is shorter than a width length or a height length of the current picture.
1 . A method comprising:
constructing a tile structure;
wherein a current picture comprises at least two split tiles,
wherein the at least two split tiles are split by a column splitting or a row splitting;
merging the at least two split tiles so as to form a tile structure,
wherein the merging is based on a merge number information,
wherein the merge number information indicates how many of the at least two split tiles are merged; and
reading a loop_filter_across_tiles_enabled_flag, wherein the loop_filter_across_tiles_enabled_flag specifies that loop filtering across tiles is enabled.
2 . A method of video encoding comprising:
encoding a tile structure;
wherein a current picture comprises at least two split tiles,
wherein the at least two or more split tiles are split by a column splitting or a row splitting;
merging the at least two split tiles a so as to form a tile structure,
wherein the merging is based on a merge number information,
wherein the merge number information indicates how many of the at least two split tiles are merged; and
reading a loop_filter_across_tiles_enabled_flag, wherein the loop_filter_across_tiles_enabled_flag specifies that loop filtering across tiles is enabled.
3 . A method of video decoding comprising the method as claimed in claim 1 .
