Description Technology leaders are rapidly responding to the looming challenge of 4K video both by embracing new production methods and by validating compatibility with existing workflows. This validation needs to cover all aspects of the production process, including capture, compression, conversion, storage and delivery. Although most broadcasters today view 4K as an issue to be addressed in the future, some forward-looking groups recognize that the technology is starting to have an impact on current engineering practices. Much of today's 4K testing is being done on prototype or "first-article" system elements, but the results are already providing valuable input to help guide important business decisions for future generations of services. As new 4K systems and products reach the market, video quality testing and evaluation will continue to be important, both for processing technology performance benchmarks as well as vendor selection.
