Abstract
There is provided a video display system in which when supplying a video signal from a base station (200) to a plurality of display units (transportable one 100 and large-screen one 300), an operation instruction generator generates a screen select instruction corresponding to the direction of the user'"'"'s touch on a touch panel (121) provided on the display screen of the transportable display unit (100) that displays an image corresponding to a video signal supplied from the base station (200) and transmits the operation instruction from the transportable display unit (100) to the base station (200), and a controller included in the base station (200) controls the channel selecting operation of two turning means included in the base station (200) correspondingly to the supplied operation instruction. Stroking the surface of the touch panel (121) on the display screen of the transportable display unit (100), the user can transfer an image between the plurality of display units (100, 300). Thus, the user can intuitively select an operation of the video display system in a manner different from that using a button on the conventional remote controller.
