grammar - Difference between 'He has been involved' and 'He has been watching TV'

From the sentence

He has been watching TV,

I understand that it is a present perfect continuous tense that started in the past and is continuing in the present time.
But I get confused at times when I hear sentences like

He has been involved.

Does it mean the same thing? That the involvement started in the past and is continuing in the present time?
If not, what is the difference?
