To operate the TV (not shown) with the remote controller
300 according to an example embodiment of the present
invention, the TV/DVD receiver button 319 is used. A user
?rst turns on the TV, presses the TV/DVD receiver button
319, points the remote controller 300 toward the TV, and then
enters a code corresponding to the brand of the TV using the
number buttons 303 while pressing the power button 301. If
the TV is turned on or off, the setting is completed.
If a stop button 339 among the DVD play related buttons
324 is pressed once, the stop position is stored in memory. If
a play/pause button 340 among the DVD play related buttons
324 is pressed, playback resumes from the stop position. If the
track, or scene is played. In the case of a VCD with a track
longer than 15 minutes, each time the button 338 or the button
341 is pressed, playback may skip back or forward 5 minutes.
For fast playback, the button 338 or the button 341 is held
down during playback. Each time the button 338 or the button
341 is held down during playback, the forward playback
speed or reverse playback speed changes in the order of
