WATERMARKING APPARATUS AND METHOD FOR INSERTING WATERMARK IN VIDEO CONTENTS

摘要

PURPOSE: A device and a method for inserting a watermark into video content are provided to process common insertion information in content encoding in advance, thereby reducing the resource consumption of a terminal for inserting a watermark. CONSTITUTION: A content receiving unit(310) receives video content from a watermark headend system. Watermark insertion information is primarily inserted into the video content. An image information image insertion unit(340) secondly inserts intrinsic watermark insertion information into video content. A message information image insertion unit synthesizes a message information image, including the watermark intrinsic insertion information, with a alpha blending type content reproduction screen.
