Claim:
A recording medium reproduction apparatus for reproducing a DVD recording medium in which recorded data and table of contents data including recording medium side reproduction restriction information for restricting reproduction of the recorded data is recorded, said recording medium reproduction apparatus comprising: recording means in which apparatus side reproduction restriction information related to recording medium side reproduction restriction information is recorded; information reading means which reads the apparatus side reproduction restriction information recorded in said recording means and also reads the recording medium side reproduction restriction information from the recording medium before reproducing the recorded data from the recording medium; comparing means which compares the apparatus side reproduction restriction information with the recording medium side reproduction restriction information each read from said information reading means; determination means which determines whether reproduction of the recorded data is to be allowed or not based on the comparison result of said comparing means; control means which stops reproduction of the recorded data and outputs and displays the recording medium side reproduction restriction information when said determination means determines that the reproduction of the recorded data is not allowed; an OSD generating means; a displaying means; and a reproducing means, wherein the recording medium side reproduction restriction information is a region code, wherein when said determination means determines that the reproduction of the recorded data is not allowed, said control means generates character signal related to an error signal and a recording medium side reproducing restriction information in said OSD generating means, and outputs and displays on said displaying means with superposing on a video signal; and wherein a reason why the stoppage of the reproduction occurs is displayed, when the apparatus side reproduction information and the recording medium side reproduction restriction information do not coincide with each other.
