I'm not sure I completely understand the problem...or maybe I do but just don't agree that it needs to be as specific as you're stating. Our (meaning the the United States) television shows are already rated. Every show on TV has a label...the type of shows or situations you're discussing are labeled as TV-MA (meaning for mature audiences only) and then have additional content labels such as L (course or crude language), S (sexual situations), V (violence). These labels/warnings are shown before all programs. IMHO, showing that something is TV-MA, SV is sufficient. I don't think it is necessary or realistic to expect that they're going to specifically say "There is a rape scene in this program." That being said, I believe True Blood is on HBO (someone correct me if I'm wrong because I'm not familiar with the program) and we all know that premium cable channels are able (and do) to show more extreme, intense scenes than you find on network television or even standard cable channels. Still, though, they do give the standard tv ratings I mentioned above.
