NAB Show Product Review: Signal Processing & Analysis - TvTechnology
Whether its IP, SDI or analog one thing is inevitable, and that’s the need for monitoring, signal processing, and test and measurement gear

The IP era in broadcasting is upon us, and there was plenty to see in this area at the 2018 NAB Show. Television is also beginning to move into its next stage of advancement—ultra high definition, high dynamic range, extended color gamut and higher frame rates.

However, whether its IP, SDI or analog signals flowing through the equipment racks, one thing is inevitable, and that’s the need for monitoring, signal processing, and test and measurement gear. There was plenty to see along these lines at the NAB Show this year.
