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.
