Whitepaper: Hitting the moving target of 4K
As the 4K resolution standard is gaining acceptance in the consumer segment – there is a need for enterprise grade AV systems to also incorporate support for them. But as is the case with any new technology standard, 4K is still a dynamic set of standards and systems designed today, with a need to plan for new features that are expected in the future.
In this whitepaper, Extron explains some critical things about 4k signal distribution and also talks about some of the things that we need to plan for in new installations.
They also try to distinguish between varied claims like “4K Capable”, or “4K Certified”, or “4K Ready” that are specified by manufacturers.
Some useful points to consider…
“Unless a manufacturer clearly defines the resolution, frame rate, color sampling, and color bit depth that their product supports, they haven’t told you what you need to know – they haven’t told you the truth.”
“When designing 4K AV systems, the primary consideration is bandwidth, i.e. the maximum data rate that needs to be supported by every system component that transports, switches, and processes the 4K video signal”
“The benefits of 4K or UHD are most evident when viewed on large screen projection systems, or when stretching a single 4K or UHD source across several screens in a video wall application.”
“Due to the high bandwidth requirements of 4K signals, the interfaces providing the signals must support very high data rates. HDMI and DisplayPort are currently the most popular interfaces capable of delivering 4K content on a single cable.”
