Nigel Tufnel, lead guitarist for film lore band Spinal Tap, famously explained to legendary (and imaginary) filmmaker Marty Dibergi that his Marshall amp, “when you need that extra punch”, went one louder… “to eleven”.
While Murideo’s next generation video generators and analyzers don’t quite go to 11K, on the far horizon when you indeed may need that extra little punch, 10K is written into the HDMI 2.1a specification. But for the foreseeable future, 8K and its more than 33 million pixels, fourfold over those of the 4K era, are what we will be contending with for signal distribution and display calibration.
Murideo testing and calibration tools are developed using our Keysight DSOX92004A, 20Ghz oscilloscope, a nearly half-million dollar reference-level, laboratory machine for performance and compliance testing of HDMI 2.1 signal devices. The precision of our products rewards us with clients such as NASA, Pixar, Imax, Sony, Sound United and worldwide, world-class integrators and calibrators like yourselves. Meeting the expectations of demanding clients is one of the challenges we thrive upon, and we feel confident new upgrades for the Murideo suite of tools places our clients in the best position for continued success.
Let’s examine which 8K solution will save you time, guarantee provable results, and become your newest partner on the jobsite.
From its launch, the MU-FXHD-KIT original Fox and Hound proved indispensable discovering system chokepoints with cabling and sorting out EDID and HDCP conflicts between sources and displays. Starting at the source and working toward the display, any error preventing signal from reaching the display was easily discoverable, confirmable, and resolvable.
The new MU-FXHD-KIT-8K retains all valuable features of the original kit such as EDID read and Copy functions, HDR static and dynamic metadata generation, and HDMI cable continuity and bandwidth testing. Bandwidth extends to 40Gbps with a maximum resolution timing of 8K60Hz, full HDMI 2.1 support with Fixed Rate Link FRL5 compliance and HDCP 2.3 verification.
Time is valuable to you and your clients and not a SKU you can simply reorder. Time can be defined as a resource directly translatable into revenue gained or retained, directly correlating to client rapport and even client retention. Rapid and accurate installation coupled with efficient trouble-shooting exemplifies expertise within your company and extends to client perception.
The Murideo Fox and Hound Kit will prove to be one of the few investments that genuinely and tangibly pays for itself.
Favored by calibrators for its seamless interface with CalMAN, the 8K Six-G and 8K Six-A generator / analyzer pair receive a bandwidth increase to 40 Gbps. Three added features residential and commercial integrator’s may find beneficial in comparison to the Fox and Hound have been incorporated into the Six series update.
One is the capability to send a Dolby Vision signal in addition to the trio of HDR signals. With Netflix content almost exclusively in Dolby Vision, verifying that every form of content is correctly playable prior to leaving a site, especially if the client has not yet established service at time of system deployment.
PC software enables a logging feature, to confirm intermittent issues with a device may exist.
When paired with the 8K Six-A, the duo are able to test for latency between the source and the display, identifying whether it is as simple as an HDMI cable or something more complex. Data analysis provided enables you to eliminate the culprit.
EDID capability has been bolstered to now provide 6 ‘canned’ EDIDs and space for 10 user copies.
Unlike the Fox and Hound kit, the 8K Six-G can be used to generate reference-grade patterns from CalMAN, Light Illusion and Argyll calibration software as a fully functional calibration tool. Integration companies that also wisely calibrate displays will find the 8K Six-G provides every pattern necessary available for comprehensive SDR, HDR, and Dolby Vision calibrations, including a custom HDR memory.
The Murideo Seven has also been the recipient of an 8K update, remaining the top portable 8K generator for manufacturing use, professional calibrators, and integrators who demand only the best gear as part of their kit. The 8K Seven mates perfectly with CalMAN and Light Illusion.
Next Gen game consoles are getting married to 8K displays in cutting edge systems around the globe. Be among the first calibrators and integrators to certify 120fps game performance with the Murideo 8K Seven.
The 8K Seven is Dolby Laboratories certified for Dolby Vision™ and Dolby Audio™ and includes an extensive array of audio system performance testing capabilities.
Murideo engineers were busy finding the best performing, highest quality 40Gbps HDMI chip sets, exhaustively tested to be assured Murideo products continue to have legendary stability, reliability, and durability to carry all of us over the threshold into the next generation of video and audio. While changes in the industry force necessary updates from 4K to 8K, Murideo has retained the same familiarity of use with our generators and analyzers so you can hit the ground running.
As always, never hesitate to contact us with questions, concerns, or comments, as we always welcome feedback for improvements you wish to see incorporated into our products.
And just for the record: The 1959 Fender Bassman amplifier had controls that went to “12”…
A light meter is an essential piece of hardware that should be in every calibrator’s kit. Many different meters can be used for display calibration, and in this article, I will explain two types with their respective pros and cons.
Two technology types define meters used in calibration: spectroradiometers, also referred to as spectral meters or spectrophotometers, and tristimulus colorimeters. Both have relative advantages, disadvantages, and use cases.
A spectroradiometer differs by sampling very precise wavelengths of light (expressed as nanometers) in corresponding amplitudes called nits (cd/m2, or candelas per square meter). Spectral meters are supremely accurate, however the pace at which they take readings can be extremely slow.
An important specification for spectroradiometer performance is optical bandwidth, detailing the “width” or wavelength of light, in nanometers. A spectroradiometer with an optical bandwidth rated at 10nm will read light accurate to a 10 nanometer tolerance. While usable for display types with broad spectral response, 10nm proves far too wide for application-specific display devices that are laser-based.
Many laser-based projectors utilize a blue laser as a component of the light engine. One characteristic for these designs is a narrow spike in spectral response, typically 4nm.
Logically, a spectroradiometer designed with a 10nm bandwidth will be unable to accurately measure 4nm wavelength, perhaps completely misreading spectral response. Laser projectors are only a few generations new compared to lamp-based machines that arguably can harken back to three-CRT based projectors.
There is good news for devices that confront this issue in the form of narrow bandwidth spectroradiometers. Top-end models feature optical bandwidths of only 2nm, capable of accurately reading current Digital Cinema projectors and future products which may become more mainstream for residential applications. Aside from their narrow bandwidth, these spectroradiometers function identical to less costly spectral meters. Designed for what might be termed mission-critical use, 2nm spectroradiometers are currently priced nearly double to those with optical bandwidths in the 4nm range.
Light meters arrive on the market in an array of technology types and with specific application advantages and disadvantages.
When meter shopping, be certain to inquire about and compare optical bandwidth as this directly contributes to light-reading accuracy, especially where calibration to laser-based projectors may be involved.
Feel free to contact us with specific light meter questions and we will be happy to assist you in selecting a perfect meter for your needs. Ideally, professional calibrators benefit in having both styles of meters at hand, but let’s save the discussion for a later date.
Bearded Bandwidth: ISE 2022 Recap
The Murideo crew is back on U.S. terra firma after a wonderful trip to Barcelona, Spain for ISE 2022. As our first international show since 2020, we were unsure of what to expect, but each one of us found it to exceed our expectations! It felt fantastic to de-Zoom and give live demonstrations of the new 8K Fox & Hound and Murideo SIX-G/SIX-A kits to eager faces on the continent. The Seven G was a tremendous hit, always drawing a crowd during display calibrations. In addition, our partners at MSolutions were exhibiting the MSTest Pro in action.
All in all, Murideo products worked overtime, giving new faces and trusted friends priceless smiles. It was great to hear the number of technicians at all levels sharing how our test gear ‘saved their necks’ during installations and service calls. This is precisely why we make accurate, affordable, easy-to-use products! Attendees who have heard of Murideo but had not personally viewed or handled our gear in person were grateful we made the effort to cross quite a few time zones to speak with them directly.
Murideo’s Jason Dustal was the host instructor for a ninety-minute presentation on RP28-HDMI System Design and Verification to an audience with a vast range of experience of more than twenty.
For Murideo, the show was a great success, and plans to see everyone at ISE 2023 have already begun. This June, our next destination is Las Vegas for InfoComm 2022 and we look forward to connecting with our extended Murideo family members!
