Methods and apparatus for generating program guides and restricting access to programs as a function of program ratings and/or program content are described. Methods of billing for services are also described. Multiple remote controls, e.g., of different types or assigned different identifiers are used. Access to program guide content and actual program content is restricted based on which remote control device is used. Program guide content and program access can be restricted based on a rating level and/or particular attributes of the program, e.g., sex, violence, adult language. For example PG-13 programs with sexual content may be restricted while PG-13 programs with violent content may be allowed to be viewed depending on what restrictions are set. Program attributes may be included in program guide information. Remotes used to provide restricted access may use different control signals from remotes used to provide unrestricted access and can be implemented as simplified remotes.
