Multilingual display device and method thereof
First Claim
1. A multilingual display device comprising:
- tuning means for converting a broadcast signal into an IF signal and outputting said IF signal;
a plurality of sound multiplex processors for detecting an audio signal from said IF signal, processing said audio signal according to a sound multiplex mode, and outputting information regarding the sound multiplex mode;
a plurality of video signal processors for detecting a video signal from said IF signal, processing said video signal according to a broadcasting system, outputting information regarding the broadcasting system, mixing input OSD signals with said processed video signal, and outputting said mixed signal for display; and
control means for outputting control signals for selecting respective corresponding processors among said plurality of sound multiplex processors and said plurality of video signal processors, said selection based upon said sound multiplex mode information and said broadcasting system information, said control means outputting said OSD signals corresponding to a particular language of a given area to said video signal processor selected by one of said control signals.

Abstract
A multilingual display device is provided with a plurality of video signal processors for processing a video signal according to a broadcasting system, and a plurality of sound multiplex processors for processing an audio signal according to a sound multiplex mode. A microcomputer automatically generates OSD signals in a language of a broadcast receiving area by means of broadcasting system information and sound multiplex mode information provided from the plurality of video signal processors and the plurality of sound multiplex processors, thereby providing the advantage of interchangeability with respect to output of OSD signals in a television. This can be used in a television having an OSD function.

4. A multilingual display method for use in a multi-broadcast signal processing system for converting a received multi-broadcast signal into an IF signal according to a broadcasting system and processing the IF signal respectively into a video signal and an audio signal, said multilingual display method comprising the steps of:
-
firstly identifying said broadcasting system via a vertical frequency and a color subcarrier of said video signal; secondly identifying a sound multiplex mode via a pilot signal for determining whether said audio signal is of a stereo broadcast or of a multilingual broadcast; and producing OSD signals in at least one language used in a corresponding area selected from a plurality of languages on the basis of the results of said first and second identifying steps. - View Dependent Claims (5, 6, 7, 8)

9. A multilingual display method for use in a multi-broadcast signal processing system for converting a received multi-broadcast signal into an IF signal according to a broadcasting system and processing the IF signal respectively into a video signal and an audio signal, said multilingual display method comprising the steps of:
-
(a) detecting a vertical ferquency; (b) transmitting a PAL-N broadcasing control signal if said vertical frequency equals a predetermined value; (c) determining a color subcarrier frequency associated with said video signal where said vertical frequency does not equal said predetermined value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
