Abstract

A video encoding apparatus may include a partitioning unit which divides a frame included in input video into a plurality of blocks; and a rate control module which adjusts a first quantization parameter value of a block corresponding to a region of interest among the plurality of blocks based on a first CBF (current buffer fullness) value of the region of interest, and adjusts a second quantization parameter value of a block corresponding to a non-region of interest among the plurality of blocks based on a second CBF value of the non-region of interest.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0109462 filed in the Korean Intellectual Property Office on Aug. 29, 2017, the entire disclosure of which is hereby incorporated by reference. technical field [0003] Exemplary embodiments relate to a video encoding device. Background technique [0004] Demand for high-resolution and high-quality video such as high-definition (HD) video and ultra-high-definition (UHD) video is increasing, and in order to handle high-resolution and high-quality video, high-performance video compression technology is available. [0005] Recently, mobile devices such as mobile phones and smart phones have been widely used, and in mobile devices with small size and limited environment (e.g., use of battery), there has been an effort to compress high-resolution and high-quality video efficiently. Various methods were studied. [0006] Recently, in order to encode...
