摘要:
For the display of certain video scenes, in a case when first restrict data has a stricter restrict level than second restrict data, an on-screen circuit (5) operating in accordance with the output of a comparator (3) alters the display on the TV screen (6) to a single predetermined color, cutting out the video scene. Alternatively, in the case when first restrict data has a more lenient restrict level than second restrict data, the on-screen circuit (5) operating in accordance with the output of a comparator (3) displays the video scene unaltered. Furthermore, the extent of the difference between restrict levels of first and second restrict data can be checked on the TV screen (6) by means of data set in attribute register (9), making it possible to prevent overly deviant restrict level settings.
