Remote computer display using graphics primitives sent over a wireless link

摘要

A remote computer display for a portable computing device (PCD) utilizing the transfer of graphics primitives over a wireless data link. The present invention utilizes a wireless (RF or optical) transmitter built into a portable computing device to send graphics commands to a remote computer display. A receiver receives the wireless signals and converts the signals into data which produces a graphics image of the remote computer display. To reduce the data link bandwidth needed to transfer images from the PCD to the remote display, graphics primitives such as HPGL are sent over the data link. The PCD includes a video driver to convert video display requests made by the PCD operating system, or an application program executing on the PCD, into the graphics primitives which are then transferred to the remote display over the data link.
