A method (100) and apparatus (60) provide dynamic content rating for digital transmissions (20) of media programs. Rather than one rating or a set of ratings be associated with an entire program or broadcast channel, content rating data relates to specific segments (44,46,52) of a program. A user of a media receiving device (66) presets rating criteria (104) relating to a level or type of content to be blocked. The preset criteria are then used to selectively block (112) presentation of those segments of content of a media program that fall outside the acceptable rating criteria. A timed length or display area (52) segment of audio, video, text, graphics, or data may be dynamically blocked based on a comparison (110) of the content rating associated with the segment and the user's preset rating criteria.
