1.1 A Word about Video Scalers

Kramer’s Digital Video Scalers are designed to convert Composite and S-Video signals to a variety of computer resolutions. Different versions are required to handle NTSC and PAL video standards. Kramer Video Scalers have many features to enhance performance. AFM (Adaptive Film Mode) is an automatic 3:2 pull-down detector that provides clear and crisp de-interlacing video from 24 frames-per-second film. It offers significant enhancements when viewing movies on a large screen. VT (Vertical Temporal Filter) can remove jagged edges and other de-interlacing artifacts for video motion sequences. Our Static Picture Detector uses a simple field merging technique to perform de-interlacing and it is very beneficial for static images or scenes with very little or no motion.

1.2 Factors Affecting Quality of Results

There are many factors affecting the quality of results when Composite or S-Video signals are de-interlaced and up-converted (scaled) to computer resolutions. Some basic precautions will ensure the best possible performance from your Video Scaler.

Output display device



of display device used. Specifically, some video projectors just look better than others. Distance between the Video Scaler and the display device – This plays a major role in the final result.



Long distances are possible, but special measures should be taken in order to avoid cable losses. These include using high quality (coax-type) cables or adding line amplifiers. Output connection cables – Low quality cables are susceptible to interference. They degrade signal



quality due to poor matching and cause elevated noise levels. Therefore, cables should be of the best quality. Coax-type computer cables are because of their superior internal shielding characteristics. Interference from neighboring electrical appliances – These can have an adverse effect on signal



quality. For example, an older computer monitor often emits very high electromagnetic fields that can interfere with the performance of video equipment in its proximity.

– The quality of the output signal will depend largely upon the type and quality
