METHOD AND DEVICE FOR CONTROLLING VIDEO BIT RATE

摘要

A method of controlling a video bit rate according to the present invention includes splitting the current frame into a plurality of first sub frames, deriving a sub frame goal bit rate for each of the plurality of first sub frames, and deriving a QP value for each of the plurality of first sub frames on the basis of the derived sub frame goal bit rate. According to the present invention, video coding efficiency may be enhanced.
