What is the difference between, 1."You are not meant to say this on t.v" and 2."You can't say this on t.v"?

Fate makes you unable to do so.

fatimah0786 2."You can't say this on t.v"

You are not permitted to do so.

Thanks. I have also heard people say, "I didn't mean to hurt you". Just now I have read a reply on this forum to a certain question: "My comma was meant to be a full stop"

The meaning of those two is:

I did not intend to hurt you.
I intended the punctuation mark to be a comma. I printed a full stop by mistake.

Thanks for answering. How can we differentiate one meaning of "meant" from the other. In the example "You are not meant to say this on t.v" why can't it mean not intended to say on t.v.

Only context can make the intended meaning clear.

I was watching a talk show in which the host asked an actor about a certain actress's cosmetic surgery and he replied saying, "Are you meant to say this on t.v?".

That has the meaning of 'are you supposed to ..?.' There could be a similar meaning of 'be supposed to' in "You are not meant to say this on t.v"

So, "meant" and "are you supposed to" can be used interchangeably?

Are you meant to and are you supposed to can usually be interchanged. In many other contexts, meant and supposed are not interchangeable.
