Taking a step back from all of the 4K enthusiasm is Joel Silver, president of the Imaging Science Foundation (ISF) and one of the A/V industry’s preeminent video experts. For well over a year, Silver has been cautioning installers that there are other fundamentals in place that should take a higher priority than resolution...
Underscoring what is happening in the video world, Silver emphasizes that 4K is just the first part of a new system. “Frankly [4K] is the least impressive part of the roll-out,” he boasts.
According to Silver, the underpublicized part of the impending video industry’s format updates is the expanded color gamut that could become a part of their final specification.
“The 2020 color space (the International Telecommunications Union Radio Communications ITU-R BT.2020 recommendation) is going to be great for laser color space, but it will be difficult for older TVs.”
“Flat-panel TVs will be expensive,” he continues. “The broadcast space already uses [the spec]. I have a 17-inch HP laptop that was part of a venture with DreamWorks and it includes Rec 709 capabilities and the Adobe Color Space that is much better than HD. The laptop also does DCI (Digital Cinema Initiatives).”
“I can in a two-minute demo show pictures in three different color spaces. Improvements in color gamut are instantaneously superior to the average viewer. Showing Adobe Color Space over Rec 709 is noticeable. Glancing at 4K, the average person doesn’t see [a noticeable difference] because it is just resolution.”Read More
