Abstract
Abstract A signal selection system for a television receiver comprises means (102, 104) for selecting a particular modulated RF signal respective of video information from a plurality of modulated RF signals corresponding to respective channels in response to a control signal; means (108) coupled to said selecting means for detecting the RF signal to produce a pair of detected baseband signals representative of video and audio information; a pair of auxiliary input terminals (111) for receiving a pair of auxiliary baseband signals representative of video and audio information from one of a plurality of external sources; memory means (120) for storing label data representative of labels comprising at least one alphabetical character and selection data associated with respective ones of said modulated RF signals and the pair of auxiliary baseband signals; data entry means (116, 118, 128) for generating the label data and the selection data under user control, wherein the labels associated with both of the modulated RF signals and the pair of auxiliary baseband signals can be any label which is convenient for a user to identify respective ones of the channels and the external source associated with the pair of auxiliary baseband signals; and a microcomputer (110) coupled to the data entry means for storing the label data and the selection data in the memory means during a programming mode and for retrieving the selection data from the memory means for selecting one of the particular modulated RF signal and the pair of auxiliary baseband signals in response to label data input by the user during a signal selection mode. <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
252 words
A signal selection system, comprising: an RF input terminal for receiving a plurality of RF signals; tuning means coupled to said RF input terminal for selecting a particular RF signal from said plurality of RF signals in response to a tuner control signal; means, coupled to said tuning means, for detecting said RF signal to produce a detected baseband video signal; a baseband input terminal for receiving a second baseband video signal; selection means having first and second input terminals for receiving said detected baseband video signal and said second baseband signal, respectively, said selection means selecting one of said baseband video signals at said first and second input terminals in response to a selection signal; memory means for storing label data representative of labels comprising at least one alphabetical character, and tuning data associated with respective ones of said RF signals for tuning said RF signals, wherein one of said labels is associated with said baseband input terminal for selecting said baseband signal; data entry means for generating said label data and said tuning data under user control; and control means coupled to said data entry means and said memory means for storing said label data and said tuning data in said memory means during a programming mode, said control means also being coupled to said selection means, said control means retrieving said data from said memory means and generating said selection control signal for selecting one of said baseband video signals in response to label data input by a user.
Claim 2
Dependent Claim
252 words
A signal selection system, comprising: an RF input terminal for receiving a plurality of RF signals; tuning means coupled to said RF input terminal for selecting a particular RF signal from said plurality of RF signals in response to a tuner control signal; means, coupled to said tuning means, for detecting said RF signal to produce a detected baseband video signal; a baseband input terminal for receiving a second baseband video signal; selection means having first and second input terminals for receiving said detected baseband video signal and said second baseband signal, respectively, said selection means selecting one of said baseband video signals at said first and second input terminals in response to a selection signal; memory means for storing label data representative of labels comprising at least one alphabetical character, and tuning data associated with respective ones of said RF signals for tuning said RF signals, wherein one of said labels is associated with said baseband input terminal for selecting said baseband signal; data entry means for generating said label data and said tuning data under user control; and control means coupled to said data entry means and said memory means for storing said label data and said tuning data in said memory means during a programming mode, said control means also being coupled to said selection means, said control means retrieving said data from said memory means and generating said selection control signal for selecting one of said baseband video signals in response to label data input by a user.
