Abstract
A method of scanning television channels at initial setup. The method includes at a first power mode, automatically scanning for channels using a first scanning setup procedure during which the television is unusable by a user. The first power mode is when the television is at a full power mode. The detected channels are automatically provided for use by the television upon completion of the first scanning setup procedure. The method further includes automatically scanning for channels using a second scanning setup procedure at a second power mode following the first power mode. The second power mode is at a lower power mode than the first power mode, and the second scanning setup procedure is more time consuming in comparison to the first scanning setup procedure. Additional channels not detected during the initial setup by the first scanning setup procedure are automatically detected at the second power mode.
