November 19, 1999 Replacement page IX, invention description: _ [Technical field of invention] The present invention relates to a signal format detection module and method thereof, particularly to a digital display device for detecting Prompt for the received signal format. [Prior Art] Digital Television (DTV) is a digital broadcasting system that converts a television signal into a "digital signal" by using the "analog signal" currently used by multiplex processing, modulation and other processing technologies. . The digital TV broadcasting system integrates with computer equipment and network systems through the advantages of bandwidth. On the one hand, it can provide broadband Internet connection. On the other hand, users can also have "online on-demand interactive programs" and "instant services" to freely select favorite TV programs, arrange personal viewing programs, and make TV programs. Broadcasting achieves two-way interactive communication, creating a win-win situation for system operators and users. Especially today, TV and audio broadcasting have become very popular and developed very well in the world. With the continuous advancement of technology and the continuous broadcasting of digital TV and digital broadcasting in the world, I believe that the number will be Dear for people's daily necessities • One of the current formats of digital TV video signals (ie resolution), including high-definition 10801 (transmission rate 33kbps) and Xiao (transmission rate of 45 (4) enhanced enamel (transmission rate η kbps) and the standard 昼f of Na (transfer rate kbps). In the above specifications, the number represents the number of horizontal scan lines per face, and the letter I represents the face is interlaced with a cat. She (4) buckles fat, and the letter p stands for piOgressivesean. However, 'when the user watches the number of eyes,' it is impossible to know the video signal received by the current digital TV, ',,,, Therefore, in order to obtain better display quality, most users directly choose the format of the page that is replaced by the page on November 19, 1999. Thus, when the digital TV receives the video signal When the display format is higher than the selected display format, the display quality will be degraded.
