BrightEye 90-FA HD Up/Down/Cross Converter and ARC with Analog Audio and Optical Output
BrightEye-4
PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES
When images are converted between different formats, color spaces, and resolu-
tion 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. The BrightEye series
of up, down, and cross converters were designed specifically with this in mind
and provide the highest possible level of signal processing quality.
Key aspects of this design are:
1) The Standard Definition analog inputs and outputs feature 12-bit quantiza-
tion, with 4-times oversampling and 4:4:4 internal processing. This allows
for better separation of real image content from artifacts.
2) The RF aspects of the electrical performance of the SDI inputs and outputs
have been carefully optimized for reliable and dependable SDI I/O perfor-
mance even under adverse conditions. Real-world operation of these ports is
at nearly twice the industry accepted specification of 100 meters of digital
cable.
3) Input signals are upsampled to 4:4:4 spatial resolution in RGB colorspace
and adaptively de-interlaced. This enables all of the geometrical conversions
of the image to be performed in the Progressive domain. This enhancement
to the temporal resolution of the image is a key contributor to final image
quality, even if the final output is interlaced.
4) The colorspace and geometrical conversions of the signal are performed at up
to 16 bits of resolution.
5) The final output signal is built from this intermediate progressive
workspace, which is the most uncompromised version of the image possible.
It provides the best possible starting point from which to create the final
output signal.
