Dolby Labs approved, the 8K SEVEN is found in use by prominent world-class manufacturers across the globe for testing Dolby Vision™ and Dolby Audio™ codec compliance. Video display, source device, AVR and signal extension manufacturers have discovered the unparalleled aggregation of comprehensive audio and video tests hosted by the 8K SEVEN are invaluable benchmarks for assessing product development, design progress evaluation, performance confirmation, and final quality control assurance. 

Meticulously engineered with runaway ambition, the Imaging Science Foundation certified 8K SEVEN has an arsenal of more than 1,000 patterns, FPGA-generated or uncompressed YUV files, from industry testing and calibration industry leaders such as Diversified Video Solutions, ISF, Portrait Displays, PVA, Sony Pictures, Spears & Munsil, and Bill Wetzel. SDR, Dolby Vision, HDR10 and HLG patterns also include BT.2020 native 10bit & 12 bit content, making the 8K SEVEN the consummate display calibration or A/V evaluation instrument. Users may choose to construct custom test signals combining any video format with any audio format and use reporting functions to log results or perform more intrinsic test tracking with included protocol analyzation. Through the USB 3.0 interface, up to 3 minutes of 4K/60 4:4:4 motion playback may be user-uploaded. Playback at 120fps (@1080p) is also available from the 8K SEVEN. 

Phenomenally well-sorted video generation is not the only attribute crafted into the 8K SEVEN. Unmatched attention to detail, maintaining exacting audio standards, was equally adhered to as would be expected from a Dolby Laboratories approved test device. Audio tests include A/V Synchronization, Latency Offset and all Dolby Audio streaming codecs: Dolby Digital, Dolby Digital Plus (w/Atmos), Dolby MAT (w/Atmos) , and Dolby TrueHD (w/Atmos). Audio tests can be transmitted via HDMI and eARC, with ARC supporting LPCM 5.1 & 7.1, Dolby Digital, and Dolby Digital Plus (w/Atmos). A built-in photodiode sensor with microphone enable real-time sync and latency measurements from HDMI, eARC, and ARC. 

A bright, easy to read large 7” 1080p LCD screen crisply illuminates the 8K SEVEN’s data pages and test results. Simple keypad touchpoints enable easy menu navigation, preset and shortcut selections and provide media control. When connected to a local area network, the built-in Web Interface provides more accessible device control, including management of multiple units on the same network while retaining individual control.   

Calibration specialists and seasoned video professionals of all stripes will find the Murideo 8K SEVEN to be a brilliantly executed mature product, wrapped in an elegant industrial design equipped with a compelling array of practical features, finally laying to rest the arguments and perceptions of the past that high-precision test instrumentation must sport esoteric pricing to bear the hallmark of authenticity.
