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.
