<p>A controller, for use in a video signal encoding system, 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 the GOP's being classified into three types of frames, each of the frames being divided into a multiplicity of macroblocks. The controller comprises: a state machine for generating a control sequence in response to a signal denoting a start of the frame and the type of a frame currently encoded; a calculation unit for providing a first set of values; a processing unit for providing a set of control values for each of the macroblocks in response to the control sequence and the first set of values, the set of control values denoting the inter/intra mode, the field/frame DCT mode and the quantization parameter, based on a macroblock number currently encoded and initial constant values; and a memory and input/output unit for storing the initial constant values and providing them to the processing units, storing the set of control values and providing them to be used in encoding the video signal. <IMAGE></p> |
