Abstract
Abstract In a television receiver having a function of picture-in-picture, a character caption on a sub-screen is displayed at an easy-to-see position to enable the content of the sub-screen to be easily understood while looking at the main screen, wherein when either one or multiple sub-screens are displayed in the main screen, the character caption corresponding to the displayed sub-screen is displayed at a proper position to the main screen or on a position displaced from the main screen, it may also be displayed with a character having a shade or displayed with a blanched character or the like, thereby even while watching the main screen, the content of the sub-screen projected may easily be understand through the character caption.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A television receiver for displaying a plurality of image signals from a plurality of image sources simultaneously on a screen, said television receiver comprising: selecting means for selecting a first image signal from said plurality of image signals and a corresponding audio signal; an audio processing circuit for processing said audio signal corresponding to said selected first image signal; and character caption processing means for processing a character caption corresponding to a second image signal and for displaying said character caption simultaneously with said plurality of image signals, wherein said character caption processing means processes a plurality of character caption corresponding to said plurality of image signals with the exception of said first image signal and displays each of said plurality of character captions in a predetermined position of said screen.
Claim 2
Dependent Claim
131 words
A television receiver for displaying a plurality of image signals from a plurality of image sources simultaneously on a screen, said television receiver comprising: selecting means for selecting a first image signal from said plurality of image signals and a corresponding audio signal; an audio processing circuit for processing said audio signal corresponding to said selected first image signal; and character caption processing means for processing a character caption corresponding to a second image signal and for displaying said character caption simultaneously with said plurality of image signals, wherein said character caption processing means processes a plurality of character caption corresponding to said plurality of image signals with the exception of said first image signal and displays each of said plurality of character captions in a predetermined position of said screen.
Claim 3
Dependent Claim
133 words
A television receiver for displaying a plurality of image signals from a plurality of image sources simultaneously on a screen, said television receiver comprising: selecting means for selecting a first image signal from said plurality of image signals and a corresponding audio signal; an audio processing circuit for processing said audio signal corresponding to said selected first image signal; character caption processing means for processing a character caption corresponding to a second image signal and for displaying said character caption simultaneously with said plurality of image signals; and means for changing colors of outer contours of said plurality of image signals with the exception of said first image signal, wherein said character caption processing means displays a color of said character caption with the same color as a corresponding one of said contours.
Claim 4
Dependent Claim
