Display system for facilitating the setup of a tuning system
First Claim
1. In a tuning system for a receiver of the type including memory means for storing tuning information for various tuning positions a user may select and control means for controlling the entry of said tuning information into said memory means during a programming mode of operation of said tuning system and the retrieval of tuning information from said memory means during a normal mode of operation of said tuning system, apparatus comprising:
- mode selector means coupled to said control means for selectively generating one of a NORMAL signal to cause said tuning system to operate in said normal mode and at least a TUNE signal to cause said tuning system to operate in said programming mode;
tuning position means coupled to said control means for generating binary signals corresponding to said tuning position in response to user control;
tuning voltage means coupled to said control means for generating binary signals representing tuning voltages corresponding to said tuning positions in response to user control;
display means for displaying predetermined symbols in response to respective coded arrangements of binary signals; and
multiplexing means for selectively coupling said binary signals corresponding to said tuning positions to said display means so that tuning position symbols for identifying said tuning positions are displayed in response to said NORMAL signal and coupling predetermined ones of said binary signals representing said tuning voltages to said display means so that numbers related to said tuning voltages are displayed in response to said TUNE signal.

Abstract
In a tuning system for a television receiver including a memory for storing binary signals representing tuning voltages corresponding to various channels a viewer may select, during a tuning voltage setup mode in which the binary signals representing the tuning voltages are generated in response to viewer control, a multiplexer couples predetermined selected ones of the binary signals representing the tuning voltages to a digital channel number display unit to provide a viewer with an indication of the relative tuning position. The multiplexer also couples binary signals representing the letter "A" to the channel number display during the tuning voltage setup mode to distinguish the tuning voltage setup mode from other modes of operation of the tuning system. In addition, during a channel selection setup mode, in which a viewer selects the channels he does not wish skipped during normal operation of the tuning system, the multiplexer couples binary signals representing the letters "CH" to the channel number display to distinguish the channel selection tuning mode from the tuning voltage setup mode and the normal operating mode.
