What Could Possibly Go Wrong? Test Patterns for Digital TV Systems
When we left analog TV behind, we left behind the analog problems. We thought Digital TV would be perfect, but it came with its own problems. However, we still used an analog test pattern: Color Bars, which was no longer very helpful. New test patterns were needed. This talk will review how TV systems work, from lens to display, including the new HDR High Dynamic Range systems, and describe how the "Sarnoff" suite of test patterns reveals the missteps and mismatches that commonly occur in complex video production environments.
