Document Type and Number:
WIPO Patent Application WO/2019/076344
Kind Code:
A1
Abstract:
Embodiments of the present application provide a reference block selection method and apparatus for an encoding unit, an electronic device, and a storage medium. The method comprises: obtaining a target reference frame set of a target video frame to which a target encoding unit belongs, wherein reference frames comprised in the target reference frame set and the number of the reference frames are configured according to a frame type and a frame level of the target video frame; and selecting a reference block of the target encoding unit from the reference frames comprised in the target reference frame set. In the technical solution provided by the embodiments of the present application, compared with the prior art, reference frames comprised in a target reference frame set and the number of the reference frames can be limited adaptively according to a frame type and a frame level, thereby reducing the computing of reference block selection for a target encoding unit, and thus improving the efficiency for selecting reference blocks for encoding units.
