I can't play Splitscreen on Minecraft (PS3)?

I have two controllers, two accounts, when I enter a game I press Start on the second controller and it doesn't work.

The only thing you need to play split screen is an HDMI Cord if you dnt have tht hooked up to the ps3 it won't let you play split screen

DUDE WTF I GAVE YOU ALOT OF CARS AND YOU JUST GET OFFLINE IF YOU DON't GIVE ME GHOST IN A WEEK I WILL PUT A BOUNTY ON you and sorry for the caps didn't mean tht but dude foreal I have $0 left don't be like that getting my hopes up for nothing and I will mess with you on gta online

The PS3 has a camera in it and it sees that there's only one player in the room.
