  In recent years, people's demands for television functions are increasing, and people are enjoying excellent visual effects with televisions that emphasize functions such as high fidelity, high image quality, and surround sound. However, in the conventional television broadcasting system, regardless of the individual likes and dislikes of the viewer, the television station determines the contents and broadcast time of all programs, and the television is only used for watching those programs. With the spread of digital technology and the advent of the Internet era, the use of television has expanded, and viewers not only receive image and music data passively, but also select and store necessary data according to their own needs. You can not only enjoy high-quality images and music, but also use the Internet and various interactive services. In addition, the application of digital technology to television is free to edit the broadcasting system of the television program and broadcast it at the broadcast time decided by himself, watch the game at his favorite angle, or have interest in the news It is a new trend of next-generation broadcasting technology, because only a part can be taken out and viewed.

  However, since the digital TV signal is processed by the digital system and is different from the conventional analog system of the TV, the analog TV currently used in almost all homes cannot directly receive the digital TV signal. . However, if a dedicated tuner device is installed in the analog TV, the digital TV signal can be viewed using the analog TV. There are basically three ways to watch digital TV.

1 How to install a converter on an analog TV: If a digital converter (Set-Top Box: STB or IRD) is installed on an analog TV, the digital TV signal can be received using the analog TV. Converts the received signal and displays it on the screen of an analog TV, and has functions such as signal reception, demodulation, demultiplexing, decompression, encryption / decryption, video data conversion processing and remote control signal reception. It is even higher.
2. How to use digital TV: Digital TV has a built-in digital converter, so you can watch digital TV programs as they are.
3. How to install a DTV card on a personal computer: Several manufacturers and TV manufacturers have jointly developed DTV cards, and will be able to view digital TV on personal computers in the future.

  However, when viewers watch digital TV, they need to use the remote control to select the channel and use the mouse on the monitor screen to select the appropriate display of the program or function table they want to watch, Very inconvenient to use.

The inventor of the present invention has devised an apparatus for positioning a cursor by photographing operation of the monitor screen of the present invention through unrelenting research, experiment and improvement in view of the above-mentioned drawbacks of the prior art.
