Abstract

An image signal processing device and a computer system integrating the image signal processing device. The image signal processing device includes a demodulator, a video processor, a non-interleaved signal processing unit, a microprocessor and a computer signal converter. The image signal processing device can turn on the display immediately and watch the image signal, record the image signal on the storage medium of the computer, play the image signal recorded on the storage medium of the computer on the display, and watch the image signal at the same time and execute the functions of computer software applications. Adding another demodulator and another video processor to the image signal processing device can also provide a picture-in-picture display function on the display. The video signal processing device can be integrated into a monitor or a computer, or can be used as an external video signal processing device.

Description

technical field [0001] The present invention relates to an image signal processing device, and in particular to an image signal processing device which can instantly turn on a display and watch image signals and record image signals in a computer and a computer system integrating it. Background technique [0002] Recently, due to the rapid popularization of liquid crystal displays and liquid crystal televisions, the technology of converting television signals into liquid crystal display signals has also developed rapidly. Adopting LCD TV is an important trend in the future. In addition, the increase in computer computing speed and the increase in storage media capacity are helpful for storing large-capacity video data. Watching the TV signal on a separate LCD screen, or recording the TV signal to the hard disk of the computer is very desirable. [0003] Traditionally, a TV card is installed in the computer, and the TV signal can be watched through the display screen of the...
