The Hong Kong television content rating system is held up by the generic code of television programs, standard of the Broadcasting Ordinance (Cap.562) of December 11, 1995. The current ratings are:
- G: General. All ages are allowed to view the program.
- PG: (Parental Guidance Recommended): Programs with this rating are unsuitable for children; parental guidance is recommended for children to watch.
- M: (Mature): Programs are recommended only for viewers 17 years or over.
Programs that are classified as either PG (Parental Guidance Recommended) or M (Mature) should not be broadcast between 4:00 pm and 8:30 pm on any day, as this broadcast time is only suitable for the Family Viewing Hour programs.
