Abstract

Provided are an apparatus and method for controlling program conversion according to program protection information. The method for controlling conversion of a broadcasting program includes: demultiplexing a broadcasting program into broadcasting program data and program protection information; encrypting the broadcasting program data based on distribution condition of the program protection information when recordation of the broadcasting program data is requested; and recording the encrypted broadcasting program data.
