Abstract:
A method of performing time-shift function and television receiver having a tuner and a personal video recorder for storing broadcast programs of at least one channel enables a broadcast program of a currently tuned channel to be continuously and efficiently stored to enable time-shifting, regardless of an interruption by switching channels or changing input sources or even in the case of an inadvertent power-off condition. The method includes steps of setting a time-shift lock function; storing in the personal video recorder the broadcast program of a first channel that is currently viewed; storing in the personal video recorder the broadcast program of a second channel and the broadcast program of the first channel, if the currently viewed first channel is switched to the second channel; and supplying power only to the tuner and the personal video recorder, if a power-off condition occurs, wherein the supply of power to the tuner and the personal video recorder causes a continuous storing of the broadcast programs of the first and second channels in the personal video recorder.

Claim (Index 1):
A broadcast receiver, comprising:\n a tuner configured to receive a broadcast program of at least one channel, wherein the tuner is further configured to tune to a first channel as a currently viewed channel; a personal video recorder configured to store the received broadcast program of the at least one channel including the first channel; a user interface configured to output a user command signal to perform at least one of a channel switching operation to change the currently viewed channel from the first channel to a second channel or a power-off operation, wherein the user interface is comprised of at least one of a local keypad or a remote controller; and a controller configured to control, according to the channel switching operation from the user interface, the personal video recorder to store together both the broadcast program of the first channel and a broadcast program of the second channel, and wherein the controller is further configured to supply power to the broadcast receiver's elements that are necessary to store the received broadcast program of the at least one channel including the first channel if the user command for performing the power-off operation is output from the user interface, wherein the necessary elements include the tuner and the personal video recorder.
