Abstract
A controller, for use in a video signal encoding system, which decides an inter/intra mode, a field/frame DCT mode and a quantization parameter, wherein the video signal contains a multiplicity of GOP's each of which is classified into three types of pictures, with each of the pictures being divided into a multiplicity of macroblocks. The encoding system encodes the video signal on a macroblock basis. The controller is provided with: 1) a state machine for generating a control sequence which includes a plurality of control signals in response to the type of a picture currently encoded and a signal denoting a start of the picture; 2) an arithmetic unit, for generating in response to the control sequence, a set of control values which denote the inter/intra mode, the field/frame DCT mode and the quantization parameter for each of the macroblocks in the picture, by calculating a group of predetermined equations based on the sequential number of the macroblock currently being encoded and predetermined initial constant values; and 3) a memory and input/output unit for storing the initial constant values, providing the initial constant values to the arithmetic unit, storing the set of control values determined by the arithmetic unit and providing the control values to be used in encoding the video signal.
