Also, while I can't find a definition for obscenity, a later section bars the transmission of it over cable and subscription services. So it would seem that the sort of material that is already being transmitted on Cinemax, HBO, or the Playboy Channel is not what is considered "obscene". I see there are still pornography shops and strip clubs still around, so whatever the definition of "obscene" must be, it must not involve garden variety, hardcore pornography.
