Abstract

A bi-directional communication system comprising abase apparatus and a display apparatus. The display apparatus is a portable liquid crystal display for viewing video programs and browsing the internet. The base apparatus contains a television tuner for receiving broadcast signals and wirelessly transmits programming to the display apparatus. An infrared remote control device connected to the base apparatus is used to control various external input devices (e.g., a VCR or DVD player). Control menus for the base apparatus and the external input device can be displayed on the display apparatus. The display apparatus contains a touch screen, so that a user can select operational commands for controlling the base apparatus and external input devices. The display apparatus wirelessly transmits selected operational commands to the base apparatus, which then retransmits the commands to the appropriate external input device using the infrared remote control device.

Claims

1-28. -28. (canceled)

29. A bi-directional communication method for a bi-directional communication system including a display apparatus and a base apparatus, said method comprising the steps of:

wirelessly transmitting an information signal from a website to said display apparatus;

wirelessly receiving at said display apparatus the information signal from the website;

displaying a video corresponding to said information signal on a display screen of said display apparatus;

displaying an operation display on said display screen, said operation display comprising a plurality of display items corresponding to user selectable operations;

detecting a touched position corresponding to a location at which a user touches a touch screen provided on said display screen;

generating an operation signal corresponding to the display item displayed at the touched position on said display screen;

wirelessly transmitting said operation signal from said display apparatus to said base apparatus;

wirelessly receiving at said base apparatus said operation signal from said display

generating a control signal when said operation signal corresponds to an operation of an external input apparatus; and

transmitting said control signal from said base apparatus to said external input apparatus;

whereby said external input apparatus executes said operation.
