Abstract
The embodiments relate to an encoder for encoding a bitstream representing a sequence of pictures of a video stream. The encoder is operative to divide the pictures into blocks of different types, such as coding units CUs, prediction units PUs, and transform units TUs, which are associated with each other. Two sizes are possible for the blocks and the possible combinations are restricted to three cases: 1) all blocks are of large size, 2) the CUs and PUs have large size, while associated TUs have small size, 3) all blocks are of small size. The possible combinations are defined for a part of a picture and compared against each other using a decision tree. In this way an advantageous block size configuration for encoding the bitstream is determined at a reduced computational cost.
