Wireless video sender and wireless keyboard,joystick for tv



I just got a video audio transmitter 2.4 ghz and 100 meters range for my pc, $110 usd , works ok but now I need a mouse and keyboard to play games and use pc on my television , needs to be radio waves I think , no line of sight , its about 15m to the pc from the lounge , mabey even a infrared repeater Ive seen them.
I remember seeing on the web ,about a year ago at a computer show in atlanta where they had a device that did it all video,audio,mouse,keyboard,joystick looked great anyone know if these are for sale yet and what they are called?
