Method and apparatus for processing video signal

A method of decoding a video, the method comprising:

• performing inter-prediction for a current coding block based on motion information thereof;
• determining, based on a first flag of 1-bit, whether to divide the current coding block into two partitions or not;
• when it is determined to divide the current coding block, determining, based on a second flag of 1-bit, whether to divide the current coding block symmetrically or asymmetrically;
• and
• determining, based on a third flag of 1-bit, whether to divide the current coding block in a horizontal direction or in a vertical direction,
• wherein when it is determined to divide the current coding block asymmetrically, the current coding block is partitioned into a first partition that has a ¾ size of the current coding block and a second partition that has a ¼ size of the current coding block, and
• wherein locations of the first partition and the second partition in the current coding block is determined based on a fourth flag of 1-bit.

A method of encoding a video, the method comprising:

• performing inter-prediction for a current coding block based on motion information thereof;
• encoding a first flag of 1-bit specifying whether the current coding block is divided into two partitions or not;
• when the current coding block is divided into two partitions, encoding a second flag of 1-bit specifying whether the current coding block is divided symmetrically or asymmetrically;
• and
• encoding a third flag of 1-bit specifying whether the current coding block is divided in a horizontal direction or in a vertical direction,
• wherein when the current coding block is divided asymmetrically, the current coding block is partitioned into a first partition that has a ¾ size of the current coding block and a second partition that has a ¼ size of the current coding block, and
• wherein a fourth flag of 1-bit which is used to determine locations of the first partition and the second partition in the current coding block is further encoded.

A non-transitory computer-readable medium for storing data associated with a video signal, comprising:

• a data stream stored in the non-transitory computer-readable medium, the data stream being encoded by an encoding method which comprising:
• performing inter-prediction for a current coding block based on motion information thereof;
• encoding a first flag of 1-bit specifying whether the current coding block is divided into two partitions or not;
• when the current coding block is divided into two partitions, encoding a second flag of 1-bit specifying whether the current coding block is divided symmetrically or asymmetrically;
• and
• encoding a third flag of 1-bit specifying whether the current coding block is divided in a horizontal direction or in a vertical direction,
• wherein when the current coding block is divided asymmetrically, the current coding block is partitioned into a first partition that has a ¾ size of the current coding block and a second partition that has a ¼ size of the current coding block, and
• wherein a fourth flag of 1-bit which is used to determine locations of the first partition and the second partition in the current coding block is further encoded.
