Gamut Error

The total range of the SDI 10bit signal is 0 to 1023. The range 0 to 3 and 1020 to 1023 are the reserved values for Sync, and the total video signal range is 4 to 1019.

In a video signal, each primary component should lie between 0 and 100% of the video range between black level and peak level (R and G and B). Ideally, video levels should lie within the specified limits so that programs can be distributed without adjustment.

100% White pattern: Y - 940, Cb - 512, Cr - 512. 0% Black pattern: Y - 64, Cb - 512, Cr - 512

Expected Video Range: 64 to 940

In practice, it is difficult to avoid generating signals slightly out of range, and it is considered reasonable to allow a small tolerance. Therefore, the EBU recommends that the RGB components and the corresponding Luminance (Y) signal should not normally exceed the “preferred minimum/maximum” range of digital sample levels in the table below.

SystemBit Depth	Range in Digital Sample (Code) Values
	Expected Video Range	Preferred Min. / Max. Total	Video Signal Range
10 bit 64 - 940 20 - 984 4 - 1019

Supports 12G-SDI Single Link Square Division signal format

The OBM-U**8K series can display 12G-SDI Single Link 4K/UHD signals as well as 3G-SDI Quad Link signals. This is already a very useful feature, compared to competitors' monitors.

Most of the single link 12G-SDI signals are displayed as 2-S.I. format on the screen. But, the single link 12G-SDI signals with Square Division format are increasing. In order to meet this requirement in the location and studio, the OBM-U**8K series support both 12G-SDI Single Link 2-S.I. mode and 12G-SDI Single Link Square Division mode.

Meets the Return Loss Standard, SMPTE ST 2082-1:2015

In the professional broadcasting video industry, Return Loss is an important parameter that measures the reflected signal that bounces back from a terminated device. If the broadcast monitor has the poor return loss, the level of reflected signal negatively impacts the signal integrity of the loop-out signal.

The OBM-U**8K monitors meets the requirements of Return Loss specified in SMPTE ST 2081-1:2015, so that the OBM-U**8K monitors provides the high signal fidelity.
