The present invention relates to an automatic language selection apparatus based on a broadcasting method, and more particularly, to automatically select a language that matches the color television standard method used in South America, according to the characteristics of the country, and also manually desired by the viewer. The present invention relates to an automatic language selection device by a broadcasting method for selecting a language and displaying it on an on-screen display device of a television receiver.

At present, several countries in Latin America use NTSC-M, PL-M and PAL-M as a standard for color television in a limited area. The country that adopts NTSC-M is Chile. , Mexico, Colombia, Peru, etc. The countries that adopt PAL-M system use Paraguay, Uruguay, Argentina, etc., and use Spanish as public broadcasting language. Portuguese language is used as public broadcasting language.

For example, many countries adjacent to South America receive a three-system system on one TV because of the tight broadcasting channel, so that South American viewers can use a remote control, such as a remote control device, to manually watch television. There was an inconvenient disadvantage of manipulating a language consistent with the color television standard.

Another problem is that if a producer wants to manufacture a large amount of color television and export it to Brazil, the public broadcasting language of the country (eg Brazil) (eg Portuguese) must be pre-set in the internal system during the color television manufacturing process. In addition, if you want to export a small amount of products to Chile, you have to set the language (e.g. Spanish) corresponding to this country (e.g. Chile) in advance. There was also an inefficient problem in the manufacturing process.

Therefore, the present invention was created to solve the above problems, and the present invention automatically selects a language that matches the color television standard used for the characteristics of each country, and the viewer manually selects the language. Another object of the present invention is to provide an automatic language selection apparatus based on a broadcasting method that enables a producer to simplify the color television manufacturing process and improve productivity.
