[0007] However, in such a digital program receiver, when a program program with a 4:3 aspect ratio is reproduced on a 16:9 display screen, or a program program with a 16:9 aspect ratio is reproduced on a 4:3 display screen, the The title included in the program signal does not block the screen, but is displayed at an appropriate position. The user repeatedly inputs the function key to change the title position to a blank area other than the screen where the video image is reproduced. operation, causing a lot of inconvenience

The invention is used to control the state of receiving the digital program signal with a picture aspect ratio different from the currently used digital program receiver, and to automatically change the display position of title data of the received program signal in order to fit different picture aspect ratios. The receiver consists of: a title data splitting unit used to split the title data from the received program signals; a title data processor used to display the title data split from the program signals on the title position defined by a picture with a preset aspect ratio; and a controller used to determine the title position in an area where on picture with a preset aspect ratio is displayed in term of the picture aspect ratio information carried by received program signals.
Description
【Technical field】 [0001] The present invention relates to a title position setting device and method based on the picture ratio of a digital program receiver, and more specifically, it relates to a digital program receiver having a display picture with a specific picture ratio, which can be automatically set to be applicable. The title display position in other aspect ratios of the digital program signal. 【Background technique】 [0002] As we all know, the emergence of digital programs has made it possible to watch high-quality and high-quality digital programs. According to the development of such digital TV programs, new digital program receivers are continuing to accelerate. [0003] Such a digital program is producing a program that realizes a wide-screen image with an aspect ratio of 16:9, and the display screen of a digital program receiver that receives the digital program signal with a wide aspect ratio is also providing a 16:9 image size. [0004] On the other hand...
