摘要

The present invention relates to a DTV, and more particularly, to an apparatus for extracting a program logo of a DTV. An example of an apparatus for extracting a program logo of a DTV according to the present invention includes a memory for storing frame data of a specific region of a decoded image data at an arbitrary time difference, and for each pixel of frame data stored in the memory and currently input frame data. And a logo extracting unit for extracting a logo by applying the created mask to the frame data stored in the memory.;Therefore, according to the present invention, it is possible to extract the program logo from the decoded DTV image and use it as effective icon information for displaying the program in the graphic user interface environment, and it is possible to know when the logo appears and is removed in the process of extracting the program logo. So you know exactly when your program starts.;Program logo, mask, frame data
