The Wikipedia has the following information about this codepoint:

Parental controls are features which may be included in digital television services, computer and video games, mobile devices and software. Parental controls fall into roughly four categories: content filters, which limit access to age inappropriate content; usage controls, which constrain the usage of these devices such as placing time-limits on usage or forbidding certain types of usage; computer usage management tools, which enforces the use of certain software; and, monitoring, which can track location and activity when using the devices. Another feature of parental controls is the ability to blocking rating, such as Parental Advisory, TV-14 and TV-MA for TV, R and NC-17 for MPAA, and M and AO for ESRB.

Content Filters were the first popular type of parental controls to limit access to Internet content. television stations also began to introduce V-Chip technology to limit access to television content. Modern usage controls are able to restrict a range of explicit content such as explicit songs and movies. They are also able to turn devices off during specific times of the day, limiting the volume output of devices, and with GPS technology becoming affordable, it is now possible to easily locate devices such as mobile phones.
