Abstract
This invention provides an apparatus and method for changing viewing restriction level in a parental control system for reproduction of programs by means of entering into a mode for changing a previously set viewing restriction level, inputting password data, comparing the input password data with preset password data and allowing the viewing restriction level to be changed if both password data are the same, thereby preventing unauthorized changing of the previously allowed restriction level and keeping adolescents or children from viewing programs that exceed the allowed level limit.
