- Page 4 BrightEye 93 HD Cross Converter PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES When images are converted between different formats, color spaces, and resolution geometries, the need for accuracy and fidelity are extremely important. Whether upconverting from standard definition to HD formats, converting between different HD formats, or downconverting to SD, extra care must be paid to every aspect of the signal and the content of the images.
- Page 5 The BrightEye 93 can perform cross conversion between two different types of HD signals. As shown here, the 1080i input from an HD network feed is sent to the BrightEye 93 where the format is converted to 720p as required for input to an HD router.

Color Difference Color Difference systems take advantage of the details of human vision. We have more acuity in our black and white vision than we do in color. This means that we need only the luminance information to be carried at full bandwidth, we can scrimp on the color channels.

This was a natural evolution from analog systems to digital implementations. With the advent of High Definition television, with even higher data rates and tighter jitter requirements, problems with this legacy genlock signal surfaced.
