Norm Hurst of Sarnoff introduced a test pattern for digital video that caught the attention of HPA Tech Retreat attendees.
“We live in a multiformat world,” Hurst said. “We have a mess on our hands, and we need a tool to verify our workflows and signal chain.”
He added that the tool had to be quick and easy to utilize, and must be usable at any point in the path. The new test pattern—two years in development—was designed so that it would remain useful through conversions.
The test pattern includes the ability to measure frequency response, compression, skin tone, motion, bit depth, pluge, twisted bars, lipsync, color space, color sub sampling, gamma and motion.
