Versatile 4K/QFHD Input Capability
The OBM U series is equipped with standard 12G-SDI input interface(x2) , 3G/HD-SDI input interface(x2) and support 4K Quad Link 2-Sample Interleave signals and 4K Quad Link Square Division signals.
The OBM U series can accept up to 3840×2160/24,25,30,50,60p and 4096×2160/24.25.30,50,60p signals.
4K Waveform Monitor and Vector Scope Display
These features allow users to monitor sources using internal Waveform and Vector Scope.
Waveform Wide mode* is supported and both Waveform and Vector Scope can be displayed simultaneously.
* OBM-U090/U170/U171 are supported.
High Dynamic Range(HDR) Display
The OBM series supports display of High Dynamic Range footage.
Postium HDR function allows users to view both highlights and shadow details of scenes at the same time, allowing users to achieve more natural and realistic images.
The OBM series supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3.
OBM-HDR provides the function of comparing HDR and SDR(Standard Dynamic Range) on the displayed image on the OBM series simultaneously.
3G-SDI Quad Link Input ⇒ 12G-SDI/3G-SDI Single Link Output
The OBM U Series can receive the 3G-SDI Quad Link 4K video signal and then loop out the signal with the single link 12G-SDI or the scaled down 3G-SDI. This function enables you to monitor the same 4K signal with the normal HD monitor next to the OBM U Series at the same time.
Image Division & Link Order
Even though the 3G-SDI quad link Square Division signals or the 3G-SDI quad link 2-Sample Interleave(2-S.I.) signals are input to the OBM U Series monitor in the wrong order, if the signal has the normal payload ID, the OBM-X310 monitor can detect the link order automatically and display the video in the correct order on the screen.
This function controls the aperture level of a video signal, and displays images on screen with sharpened edges to help camera focus operation.
Color Space / HDR / Gamma Comparison (Side by Side)
This unique function allows users to compare the two different color spaces, gammas, HDR / SDR, camera logs and any other color settings side by side simultaneously.
The comparison area can be moved and selected by using the vertical wipe pattern.
Various 4K/12G Display Modes
This function minimize the interlaced video processing time delay. This mode is also useful when displaying fast-motion interlaced video content and when reducing the delay between video and audio.
(* OBM-U090 / U170 / U171 are only supported.)
Internal Video Processing Time
This function evaluates the Luma(Y’) level of the input image. If the certain Y’ level is set, the pixels with the designated Luma(Y’) level are displayed with the zebra pattern or the color pattern. There are three modes in OBM False Color.
Wide Color Gamut Supporting DCI-P3 and ITU-R BT.2020
The wide color gamut and the advanced 3D LUT function enable the OBM series to reproduce various color spaces accurately and the excellent grayscale. You can select from color gamuts such as DCI-P3, ITU-R BT.2020, ITU-R BT.709, SMPTE-C, EBU, Native.
Gamma value is adjustable from 1.0 to 3.0 as user’s preference to monitor in the dark area of the picture.
Any pictures taken in either light or dark environment can be easily watched or analyzed.
The Black Stretch increases the visibility of subjects in dark areas, not degrading image quality in bright areas. This mode can be used to increase shadow detail without changing the absolute black level, and without affecting mid-tones.
12G-SDI over IP Supporting ST 2022-6
The OBM-X/U/W series have the SFP interface, which allows to use the various SFP modules which can fit any possible broadcast applications. The OBM-X/U/W series monitors can display the 12G-SDI over fiber and the 12G-SDI Single Link over IP through the integrated SFP interface. The OBM-X310 has the dual SFP Input cages, which enable the monitor to accept and display the Quad-Link square division and 2-Sample Interleave 4K signals over IP supporting SMPTE ST 2022-6.
Camera Log Selection
The OBM series has the integrated camera LUT of the various camera manufacturers. It allows users to load the following camera logs.
Log-C, C-Log / S-Log2, S-Log3 / J-Log1 The more camera LUTs will be updated.
Camera Log Mapped SDI Loopout
This function allows to load the camera log to the original image and then send the camera log mapped image to another monitor through SDI loop out.
Remote Control via Ethernet
The OBM series can be connected via Ethernet connection and controlled remotely on the network.
The OBM series can display closed captions with an SDI input. It supports the CEA-708(HD-SDI closed captioning standard) and CEA-608(SD-SDI closed captioning standard).
Waveform & Vector Scope Position Changeable
The position of Waveform and Vectro Scope can be changed among Left Top, Right Top, Right Bottom, Left Bottom.
System Data Copy
This function allows users to save the monitor configuration and adjustment settings on the USB memory stick and load them to other monitors. This is useful for multiple monitor systems, allowing the transfer of one monitor’s setup and adjustment data to another.
The OBM series can display various markers, including aspect marker, area marker, and center marker. In addition, the detailed display settings of each marker are allowed. For example, the color, brightness, horizontal/vertical position, and thickness of aspect markers can all be adjusted.
Custom Marker allows the users to place top, bottom, left, right marker lines as they want.
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 above.
Type 1: Black Zebra
When the targeted color space is selected as BT.709, the pixels outside of the targeted color space are displayed as Black Zebra.
The pixels over Y Maximum, Chroma Maximum, RGB Maximum are displayed as Black Zebra, and the pixels below Y Minimum, Chroma Minimum, RGB Minimum are also displayed as Black Zebra.
Type 2: Black & White Zebra
When the targeted color space is selected as BT.709, the pixels outside of the targeted color space are displayed as Black or White Zebra. The pixels over Y Maximum, Chroma Maximum, RGB Maximum are displayed as Black Zebra, and the pixels below Y Minimum, Chroma Minimum, RGB Minimum are displayed as White Zebra.
Type 3: Mono
When the targeted color space is selected as BT.709, the pixels inside of the targeted color space are displayed as Mono, and the pixels outside of the targeted color space are displayed as the color. In this type, black and white area is not recognized.
When HDR more is set on, HDR Waveform is displayed on screen.
The image source names and tally information can be displayed on the screen, with an external remote function via Ethernet. The TSL system protocol is supported. The color of the source name and tally color can be selectable among White, Red, Green, Blue, Yellow, Cyan, Magenta.
Password Lock for User Preset
When multiple users share the same monitor, each user can register his/her own password for color temperature and user preset data. This ensures the users correctly recall their preset data, and keep preset information safe from unauthorized use.
Custom 3D LUT File Import
The OBM series allow the user to import 3D Look-up Table for accurate and consistent color matching between individual displays as well as using customized ‘looks’ that have been created by 3rd party color-grading applications. 32ˆ³, 33ˆ³, 64ˆ³, 65ˆ³ cube file are supported.
When the 4096 x 2160(1.89:1) signal is fed to the 1920×1080(16:9) resolution sceen, if you select Zero Scan mode, the whole picture is displayed on the screen, with maintaining 1.89:1 ratio.
