1. A remote control system, comprising:
- handheld remote transmitting means having a pointing axis and including transducing means disposed for radiating a plurality of predetermined angularly spaced information beams when energized;
means for energizing said transducing means during a transmission period always having first and second portions, said transducing means being individually energized during said first portion with energizing signals corresponding to associated ones of said plurality of beams;
data input means mounted on said remote transmitting means and responsive to user input for providing a data signal which is related to a dedicated function;
encoding means coupled to said data input means and said plurality of transdicers for encoding said data signal and applying an encoded data signal to said plurality of transducers simultaneously during said second portion of said transmission period; and
receiving means substantially displaced from said receiving means along a line of sight between said remote transmitting means and said receiving means for receiving said plurality of beams transmitted during said first portion of said transmission period and responsive to relationships between signals derived from said plurality of beams for producing control signals indicative of the angular displacement of said pointing axis of said remote transmitting means relative to said line of sight between said remote transmitting means and said receiving means; and
for receiving said plurality of beams transmitted during said second portion of said transmission period and responsive to signals derived from said plurality of beams for processing data related to said dedicated function.

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.

18. A display system, comprising:
-
handheld remote transmitting means, having a pointing axis and being subject to movement, for producing a signal when energized, said signal always comprising a first portion and a second portion; means for receiving said signal said receiving means being substantially displaced from said remote transmitting means along a line of sight between said remote transmitting means and said receiving means; means having a display surface and coupled to said receiving means for displaying an index at a point derived from said first portion of said signal; a plurality of transducers mounted on said transmitting means, individually energized during said first portion of said signal, and physically disposed so as to enable said receiving means to determine the position of said index on said display surface, said index at said point exhibiting movement in response to the angular position of said pointing axis of said remote transmitting means relative to said line of sight between said remote transmitting means and said receiving means; data input means mounted on said remote transmitting means and responsive to user input for providing a data signal which is related to a dedicated function; encoding means coupled to said data input means and said plurality of transducers for encoding said data signal and applying said encoded signals to said plurality of transducers simultaneously; said encoded data signal being said second portion of said signal; and means for processing signals coupled to said receiving means for processing signals in response to said encoded data signals.
