Parental Control is handled by whatever source devices you play content from. Control Center does not affect these settings in any way.
For instance, if you have set a PIN to access mature content on your TV provider set top box, you will still be required to enter this PIN to access that content.
If you have no parental controls enabled, Control Center does not add any additional controls or schemes to prevent viewing content.
How to use Safe Search
Safe Search is a way of omitting NC-17 and Adult Genre content from search results. Safe Search can be toggled on/off easily and is not a type of parental control.
In the search results screen after making a search, Safe Search can be toggled on or off at the bottom left. This option is highlighted in red below:
Use the center directional pad to navigate left and down to the Safe Search setting, press the OK button to toggle between off / on.
While Safe Search is on, Control Center will filter out NC-17 and Adult Genre listings from being displayed in search results.
