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.

摘要:
A channel display device in which a channel number which is receiving discrimination is flashed while a list of all channel numbers is displayed on a television screen. Also, a display color of the channel number discriminated as being in a receiving state is changed. Thus, a receivable channel from within a number of channels can be readily confirmed.
