Embodiment 1

[0277] If it is determined to perform subblock prediction on the block:

[0278] 1. The initial first index is included in the code stream (on the encoder side), and the maximum value of the initial first index can be M (M is an integer, M≤N, and N is the number of candidates in the motion information candidate list).

[0279] 2. The initial second index is included in the code stream (on the encoder side), and the maximum value of the initial second index may be M-m (m is an integer, m<M, and m is a predefined value).

[0280] 3. If the value of the initial second index is greater than or equal to the value of the initial first index, the value of the initial second index will be increased by a predefined value to obtain an updated second index (for example, the predefined value can be 1).

[0281] 4. The first sub-block portion of the block is predicted by applying the motion information candidate determined from the initial first index.

[0282] 5. The second sub-block po...

Embodiment 2

[0316] If it is determined to perform subblock prediction on the block:

[0317] 1. The code stream contains an indicator indicating the division direction.

[0318] 2. The initial first index is included in the code stream, and the maximum value of the initial first index may be M (M is an integer, M≤N, and N is the number of candidates in the motion information candidate list).

[0319] 3. The initial second index is included in the code stream, and the maximum value of the initial second index may be M−m (m is an integer, m

[0320] 4. If the value of the initial second index is greater than or equal to the value of the initial first index, then increase the value of the initial second index by a predefined value to obtain an updated second index (for example, the predefined value can be 1).

[0321] 5. Predicting the first sub-block portion of the block by applying the motion information candidate determined from the initial first index. ...

Embodiment 3

[0333] If it is determined to perform subblock prediction on the block:

[0334] 1. The code stream contains an indicator indicating the division direction.

[0335] 2. If the indicator represents a specific division direction (for example, divide the block along the direction from the upper left corner to the lower right corner, such as Figure 10A or Figure 10B shown on the left in the figure):

[0336] 2.1. The initial first index is included in the code stream, and the maximum value of the initial first index may be M (M is an integer, M≤N, and N is the number of candidates in the motion information candidate list).

[0337] 2.2. The initial second index is included in the code stream, and the maximum value of the initial second index may be M-m (m is an integer, m

[0338] 2.3. If the value of the initial second index is greater than or equal to the value of the initial first index, increase the value of the initial second index by a p...

Abstract

A prediction method for an image block comprising a first prediction sub-block and a second prediction sub-block, the prediction method comprising: parsing a first index from a bitstream, wherein the first index is used to obtain prediction information of the first prediction sub-block; parsing a second index from the bitstream; comparing the first index with the second index; adjusting the second index in the event that the second index is equal to or greater than the first index; and obtaining prediction information of the second prediction sub-block according to the adjusted second index.
