If your TV supports CEC then you should be able to use the remote control that came with your TV to control Kwantastic.
CEC (Consumer Electronics Control) allows for control of devices over the HDMI port.
All modern televisions support HDMI-CEC, which is a technology that allows devices to talk with each other over the HDMI cable. As buttons are pressed the remote command is sent via the HDMI cable to your Kwantastic device.
Some TV manufactures do not turn on CEC by default. See this article on how to turn on CEC on your TV.
