First Claim
1. A bi-directional communication system comprising a display apparatus and a base apparatus:
- the display apparatus, including;
information signal receiving means for wirelessly receiving an information signal from a website;
a display screen for displaying an image corresponding to the website;
operation display means for displaying an operation display on said display screen;
said operation display comprising a plurality of display items corresponding to user selectable operations and a control panel representing a remote control of an external input apparatus to be connected to the base apparatus;
a touch screen provided on said display screen for detecting a touched position on said display screen corresponding to a location at which a user touches said display screen;
operation signal means for generating an operation signal corresponding to the display item displayed at the touched position on said display screen; and
operation signal transmission means for wirelessly transmitting said operation signal; and
the base apparatus, including;
information signal transmission means for wirelessly transmitting said information signal to said display apparatus;
operation signal receiving means for wirelessly receiving said operation signal from said display apparatus;
a communication line connection for transmitting and receiving communication signals through a communication line;
control signal means for generating a control signal when said operation signal corresponds to an operation of an external input apparatus;
said control signal being the same as a signal from said remote control corresponding to said operation; and
control signal transmission means for transmitting in the infrared said control signal to said external input apparatus;
whereby said external input apparatus executes said operation,said base apparatus transmitting the received communication signal as the information signal to said display apparatus when the operation signal is an instruction for transmitting the received communication signal to the display apparatus; and
said base apparatus transmitting a transmission information through the communication line when the operation signal from said display apparatus contains said transmission information for transmittal to an object party connected to said communication line.

Abstract
A bi-directional communication system comprising a base 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.
