Scan converters price




















That's twice the frequency of television, and that's just the beginning. Super VGA and Apple Macintosh computers, which are commonly used in the home, can operate at frequencies exceeding 60 kHz. The higher the frequency, the higher the resolution of the image. Workstations used in business and industry may have scan rates that exceed kHz.

So there is obviously a frequency difference between computers and televisions. This is where scan converters come in. One of the inherent disadvantages of any scan converter is that it will decrease the resolution and frequency of the original computer video signal.

A prospective buyer must recognize that the end result of scan conversion will produce an image of lesser quality than the original. So, the decision should depend on the application in which the computer video is to be used. Other options may be available for displaying computer-video with large screen projectors. Large monitors and multi-scan projectors are available that are compatible with computer video signals.

These devices do not reduce the resolution - what you see is what you'll get. LCD panels and projectors have also become an alternative to scan conversion for display purposes.

They can be fairly expensive, but these devices will allow the signal to be displayed from the computer with minimal loss of picture quality. For video taping of computer-video signals, or for displaying on a standard TV set or monitor or projector that only handles Computer -video in teleconferencing is another growing technology that uses scan conversion to transmit computer signals over telephone lines.

The requirement for the computer signal is what determines whether scan conversion is a necessity or simply one of the options. Once we have determined the necessity, the confusing part begins because there are so many types and models of scan converters available. There are three technologies used in scan conversion, which will be discussed here.

Choosing which type is the first step in selecting a specific scan converter. This technology often uses software that resides on the video card to change the non-interlaced, This This is done by eliminating every alternate line from the computer output; thus, this method actually throws away lines of picture information.

The one advantage a software driven converter has over most others is the low price, while the major disadvantage is the lower picture quality. Not only do these units produce a very poor quality signal, but they also have many limitations in graphics card compatibility, limited features, and usually have only composite NTSC or PAL output.
