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. 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

quantization, 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

performance even under adverse conditions.

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.
