I am sick and tired of this. Please help?

Ok, so this happened about maybe 5 minutes ago. I was sitting in my family room watching a tv show and my 6 year old brother comes down and turns off the tv. I put the tv back on and told him to not do that and I only want to watch for 10 more minutes until the show is over and then he can watch. He then he said you've been watching tv all morning (which is not true, I've only watched tv for about 45 minutes) and grabs the tv remote from me. Now, I start to get a little mad and call my mom to deal with it. She can't come because she is on a business call so my brother pins me down (he is very strong for his age and besides I wasn't expecting it) and I hit my head against the table. He then pulls my hair as hard as he possibly could and pinches my . Now, I start to ger mad and scream but then he starts hysterically crying and runs upstairs to tell my mom that I hurt him. Which is not true. My mom tells us that she has to go in the shower quick and will deal with it later. So we both go downstairs and he grabs one of the remotes and I grab the other. He has the remote that controls the channels and I have the remote that turns the tv on and off. So he puts the tv on and then I turn it off. (i am sick and tired of him always getting his way). and then I say you always get your way can't we both just go to our rooms and watch tv there and he is stubborn and says no. I am going to watch it here and you are not. So then out of nowhere he says I'll be right back and then goes crying up to my mom again and says that I pulled his hair and my mom says to just get along and watch tv in different rooms so then he beats me up in the hall and then i fall down the stairs. I have a lot of scratches, and bruises, and cuts from him now. and he doesn't care. I told him to apologize and then we can both forget about it but he said no and I even apologized but he refused to. What can I do to make my brother realize that what he did was wrong and he shouldn't do that?
