Existing TV remote controls using relative coordinates have some difficulties in selecting various types of IPTV content. This paper proposes an absolute coordinates based remote control to make the selection of IPTV channels more convenient. It uses a laser pointer to point at an IPTV, a camera mounted the remote control to locate the spot pointed at, and control software to calculate the absolute coordinates of the spot pointed to on the screen.
