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.
• False Color
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.
• Fast Mode
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.
Internal Video Processing Time
• Focus Assist
This function controls the aperture level of a video signal, and displays images on screen with sharpened edges to help camera focus operation.
• High Dynamic Range(HDR) Display
The OBM series provides the function to display the High Dynamic Range footage. Postium HDR function allows users to view both highlights and shadow detail of scenes at tha same time, thus resulting in 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.
• Various Markers
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.
• Adjustable Gamma
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.
• 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.
• Closed Caption
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.
• HDR Waveform
When HDR more is set on, HDR Waveform is displayed on screen.
• In-Monitor Display(IMD)
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.
