Abstract

The invention discloses a construction method and device for a fused candidate motion information list and codec. The method comprises the steps of: obtaining a first candidate motion information set;acquiring first motion information according to the motion information in the first candidate motion information set; adding the first motion information into a first candidate motion information setto obtain a second candidate motion information set; acquiring second motion information according to the HMVP candidate motion information list; when the second motion information is different fromthe motion information in the second candidate motion information set, adding the second motion information into the second candidate motion information set to obtain a third candidate motion information set; and when the number of the motion information in the third candidate motion information set is equal to a preset threshold, taking the third candidate motion information set as a fused candidate motion information list. By implementing the invention, the construction complexity of the fused candidate motion information list can be reduced, and the encoding and decoding efficiency is improved.

Description

technical field [0001] The present invention relates to the field of video codec, in particular to a method, device and codec for constructing a fusion candidate motion information list. Background technique [0002] Digital video capabilities can be incorporated into a wide variety of devices, including digital television, digital broadcast systems, wireless broadcast systems, personal digital assistants (PDAs), laptop or desktop computers, tablet computers, electronic book readers, Digital cameras, digital recording devices, digital media players, video game devices, video game consoles, cellular or satellite radiotelephones (so-called "smart phones"), video teleconferencing devices, video streaming devices and the like .
