6.4 PROGRAM BLOCKING MAP
The following matrices demonstrate the program-blocking response of the
Z86230. The first column lists the possible entries into the Content Advisory Rat-
ing registers. The first row lists the ratings that might be recovered from the
received Content Advisory packet. Blocking action is indicated by the black
boxes.
Each matrix shows the response to the possible user selections entered into the
Content Advisory Rating registers when programs having specific Content Advi-
sory packets are received. For example, as shown in the TV Parental Guidelines
Rating matrix, entering the viewer selection from TV-PG D in register 09B causes
blocking whenever the received Content Advisory packet is TV-PG D, TV-PG VD,
TV-PG SD, TV-PG LD, TV-PG VSD, TV-PG VLD, TV-PG SLD or TV-PG VSLD.
