METHOD AND DEVICE FOR CONSTRUCTING MERGE CANDIDATE MOTION INFORMATION LIST, AND CODEC
Document Type and Number:
WIPO Patent Application WO/2020/253681
Kind Code:
A1
Abstract:
Disclosed are a method and device for constructing a merge candidate motion information list, and a codec. The method comprises: acquiring a first candidate motion information set; acquiring first motion information according to motion information in the first candidate motion information set; adding the first motion information to the first candidate motion information set to obtain a second candidate motion information set; acquiring second motion information according to an HMVP candidate motion information list; when the second motion information is different from motion information in the second candidate motion information set, adding the second motion information to the second candidate motion information set to obtain a third candidate motion information set; and when the number of pieces of motion information in the third candidate motion information set is equal to a pre-set threshold, using the third candidate motion information set as a merge candidate motion information list. The implementation of the present application can reduce the complexity of the construction of a merge candidate motion information list and improve the coding and decoding efficiency.
