REMOTE CONTROL SYSTEM FOR RASTER SCANNED VIDEO DISPLAY

摘要

The present invention is a remote control targeting and control system for use with a standard raster scanned television (70) and an associated gaming unit (60). The remote control system includes a mobile transceiver (10), and a fixed transceiver (50) which communicates with the gaming system (60). The system implements a simple communication system which allows the mobile transceiver (10) to ordinarily transmit position data and to periodically transmit button press data. The mobile transceiver (10) includes an electro-optic detector for observing when a scan line crosses a target area (74). Each time a scan line is detected, the mobile transceiver (10) transmits a pulse to the fixed unit (50), based upom which the gaming unit (60) translates the pulse into position data based on the time of its detection. The button press data is transmitted synchronously with the raster scanned television in that the fixed transceiver is caused to transmit a single pulse during each vertical retrace of the television.
