Patent ID: 8826341

Claim:
A method of controlling a broadcast receiver configured to wirelessly communicate with a remote controller, the method comprising the steps of: while receiving and displaying a broadcast signal on a screen of the broadcast receiver, receiving by the broadcast receiver a first signal from the remote controller via a first communication protocol and displaying a control icon corresponding to the remote controller on the screen; partitioning the screen of the broadcast receiver into a first and second partition, the first partition being a broadcast signal display region continuing to display the broadcast signal, and the second partition being a broadcast receiver control region that includes broadcast receiver control icons and/or subregions; wirelessly receiving a second signal from the remote controller via a second communication protocol different from the first communication protocol, the second signal representing a movement of the remote controller; moving the control icon across the screen of the broadcast receiver in response to the movement of the remote controller; when the second signal is recognized within the second partition, controlling the broadcast receiver in response to a function corresponding to the one of the broadcast receiver control icons and/or subregions; and when the second signal is recognized out of the second partition, determining whether at least one character corresponding to a displayed trace exists in a memory, if determined that the character exists in the memory, displaying a channel list including the character, and if determined that the character does not exist in the memory, displaying a previous channel list.
