PROBLEM TO BE SOLVED: To change a bit rate of an encoded video signal through small-scaled processing. SOLUTION: The invention provides a method of transcoding a video signal made up of an input bit stream representative of frames of a video, each frame being made up of blocks of pixels, there being a corresponding block of data within the input bit stream for each block of pixels. The method includes: an identification step of identifying the type of a frame of the video signal; and a control step of disregarding a configurable proportion of the data in respect of plural blocks within the frame with the predetermined type, thereby taking into account local motion activity within the frame.
