DIGITAL VIDEO ENCODER HAVING SINGLE CONTROL PATH OF VIDEO DATA, ESPECIALLY REGARDING TO REDUCING THE NUMBER OF ELEMENTS BY SIMPLIFYING CONTROL PATHS OF VIDEO DATA INTO A SINGLE PATH BY USING ONE MULTIPLIER AND AN ADDER

摘要

PURPOSE: A digital video encoder having a single control path of video data is provided to control inputted digital video data according to a finally displayed standard by using a single data control path, and to separate the controlled data, thereby reducing the number of elements. CONSTITUTION: A pixel counter(20) decides Y, Cb, and Cr signals of inputted digital video data, and outputs a corresponding control signal. A chrominance/luminance signal controller(22) controls the digital video data into a chrominance signal and a luminance signal according to a finally displayed standard by the outputted control signal. A demultiplexer(24) separates the outputted digital video data into Y, Cb, and Cr signals. A filter(26) synthesizes the outputted Y, Cb, and Cr signals, and removes noise components included in the synthesized digital video data.
