Parental control of TV channels

[JoyM]

Hi
I have basic TV channels. Along with the channels there are some free channels that shows mature content which my son some sees when we are not vigilant. He's got learning disabilities. I wanted to know if there is any app that will help to block those channels from my Android phone. Even better if there is any time control.
Appreciate if somebody guide me to the right direction.

You cannot block channels remotely via your phone.

What kind of box do you have?  If you have a Nextbox, there are parental controls where you can block channels, and they can only be watched when a PIN is entered (there is no time-based blocking).  You can also block programs by rating or content, and can hide blocked programs and channels from the guide.

IF you just have a DTA, then you're out of luck.
