A bidirectional remote control system comprising:

• an electronic appliance, and a remote control for receiving and displaying display information transmitted directly from the electronic appliance and, upon detecting an operation of displayed buttons or icons, transmitting information about a button or icon the operation of which has been detected, to the electronic appliance, wherein
• the remote control includes
• a received-information display acceptance/rejection deciding section for deciding whether or not display information necessary to control the electronic appliance that is transmitted directly from the electronic appliance is beyond the display capability of screen size that can be displayed on the remote control main unit;
• and
• a display information changing section for, if it is decided by the received-information display acceptance/rejection deciding section that the display information is beyond the display capability, changing the transmitted display information into a form that is displayable for the remote control main unit.

A bidirectional remote control system comprising:

• an electronic appliance and a remote control that controls the electronic appliance, wherein
• the electronic appliance further includes
• a display information storage section for storing therein display information for displaying buttons, icons or the like necessary to control the electronic appliance main unit;
• and
• a transmitting section for transmitting display information stored in the display information storage section to the remote control, and
• the remote control includes
• a received information storage section for receiving and storing therein display information transmitted directly from the electronic appliance;
• a display section for displaying display information stored in the received information storage section;
• a position detecting section for detecting an operation of the buttons or icons displayed on the display section;
• and
• a transmitting section for transmitting detected information about a button or icon the operation of which has been detected by the detecting section, to the electronic appliance as a control signal, and
• the electronic appliance further includes
• a display information preparing section for preparing display information for detecting a display capability of the remote control, and
• a display information transmitting section for transmitting the display information prepared by the display information preparing section, to the remote control;
• a remote-control display capability detecting section for deciding the display capability including a size of a display screen of the remote control by discriminating a response signal from the remote control in response to the display information;
• and
• a display information changing section for changing the display information including the buttons or icons necessary to control the electronic appliance transmitted directly to the remote control, according to a result of the decision by the remote-control display capability detecting section, wherein the electronic appliance is capable of being operated by the remote control.
