Abstract
The present invention relates to a video encoding and decoding method. A video decoding method for the same may include: obtaining granularity information; determining a sharing region based on the granularity information; and generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region.
Claims17
A video decoding method, comprising:
- obtaining granularity information;
- determining a sharing region based on the granularity information;
- and
- generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region.
A video encoding method, comprising:
- determining a sharing region;
- and
- generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region, wherein
- granularity information of the determined sharing region is encoded.
A video decoding apparatus, comprising:
- an entropy decoding unit obtaining granularity information;
- and
- an inter prediction unit determining a sharing region based on the granularity information, and generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region.
A video encoding apparatus, comprising:
- an inter prediction unit determining a sharing region, and generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region;
- and
- an entropy encoding unit encoding granularity information of the determined sharing region.
A recording medium storing a bit stream generated by a video encoding method, wherein the method includes:
- determining a sharing region;
- and
- generating a prediction block of a current block by using motion information of the sharing region when the current block corresponds to the sharing region;
- and
- encoding granularity information of the determined sharing region.
