PURPOSE: An apparatus and a method for the conversion of digital broadcasting contents based on program protection information are provided to control the conversion of a broadcasting program by using a protection signal inserted into a broadcasting program, thereby preventing the illegal redistribution of the broadcasting program, including protection information. CONSTITUTION: A program transform control device demultiplexes a received broadcasting program into broadcasting data and a protection signal(202). In addition, the program transform control device encodes the broadcasting data based on the distribution condition of the program protection signal when recording is required(218). Furthermore, the control device records the encoded broadcasting program data(216,220).
