Method of video coding using binary tree block partitioning

A method of video encoding, the method comprising:

• receiving input data associated with a block of video data;
• determining a block partitioning structure corresponding to a block partitioning process including a binary tree partitioning process for the block of video data, wherein the block partitioning structure represents partitioning the block of video data into final sub-blocks, wherein said determining the block partitioning structure for the block comprises:
• incorporating a first indicator associated with a current block into a video bitstream, wherein the first indicator indicates whether the binary tree partitioning process applies a binary tree partition to the current block, wherein when it is determined that the binary tree partition is applied to the current block, the current block is always split into two sub-blocks;
• and
• applying an encoding process comprising prediction process, transform process or both to the block of video data by applying the encoding process at a level corresponding to the final sub-blocks;
• wherein the first indicator is inferred as not applying binary tree partition when height and width of the current block both reach minimum allowed value, or tree depth reaches maximum allowed depth.

An apparatus for video decoding comprising one or more electronic devices configured to:

• receive a video bitstream including coded data for a block of video data;
• derive, from the video bitstream, a block partitioning structure corresponding to a block partitioning process including a binary tree partitioning process for the block of video data, wherein the block partitioning structure represents partitioning the block of video data into final sub-blocks, and wherein said deriving the block partitioning structure for the block comprises:
• parsing a first indicator associated with a current block;
• and
• determining whether the binary tree partitioning process applies a binary tree partition to the current block based on a value of the first indicator, wherein when it is determined that the binary tree partition is applied to the current block, the current block is always split into two sub-blocks;
• decode the final sub-blocks based on the video bitstream;
• and
• decode the block of video data based on the final sub-blocks decoded according to the block partitioning structure derived;
• wherein the first indicator is inferred as not applying binary tree partition when height and width of the current block both reach minimum allowed value, or tree depth reaches maximum allowed depth.
