Method and encoding/decoding of video using common merging candidate set of asymmetric partitions

摘要

The present invention provides video encoding and decoding methods using block merging, which can be applied to a high resolution video of more than HD (High Definition) resolution. A video encoding method includes partitioning a current block into a first and a second prediction unit by using asymmetric partitioning, constructing a list of common merging candidate blocks including a predetermined number of common merging candidate blocks selected from adjacent blocks of the current block, selecting at least one candidate block from among the list of common merging candidate blocks and sending information of the selected candidate block to a decoder for each of the first and the second prediction unit.

1. A video decoding apparatus, comprising:
an inter prediction unit configured to construct a list of common merging candidate blocks by including a predetermined number of the common merging candidate blocks selected from among adjacent blocks of a current coding unit, the current coding unit partitioned into a first prediction unit and a second prediction unit, wherein the common merging candidate blocks are commonly usable for the first prediction unit and the second prediction unit, generate a motion vector by reconstructing a motion parameter of a block-merged block by using at least one common merging candidate block selected from the list of common merging candidate blocks for each of the first prediction unit and the second prediction unit, and perform motion compensation by using the generated motion vector and a reference picture, wherein the inter prediction unit is configured to construct the list of common merging candidate blocks only when a size of the current coding unit is 8-by-8, wherein a coding unit has a recursive tree structure.
