Abstract
The invention relates to a display system using a remote control transmitter handunit having both a "pointing function" capability for moving a cursor displayed on a display screen by changing the angular position of the remote control handunit, and the capability of sending dedicated function data directly to the receiver. Thus, numeric data representing, for example, channel number or time of day, being unsuitable for selection from a menu is directly transmitted along with "pointing function" data transmission.
