Description

OBM-U310

The Postium OBM-U310 is designed for UHD/4K production and broadcast QC monitoring and features an native 4096×2160 4K-DCI resolution LCD panel capable of 850 cd/m² maximum luminance for HDR monitoring.

The OBM-U310 is equipped with standard 12G/6G/3G-SDI input interfaces (x2) and HDMI 2.0 input and support both 4K Quad Link 2-Sample Interleave and 4K Quad Link Square Division signals via SDI and SFP.

Closed Captioning decode and display for CEA-708(HD-SDI closed captioning standard) and CEA-608(SD-SDI closed captioning standard) is supported via SDI input. The OBM-U series accepts up to 3840×2160/24,25,30,50,60p and 4096×2160/24.25.30,50,60p signals.

Display Functions

Wide Color Space Support including DCI-P3 and ITU-R BT.2020 is controlled with an advanced 3D LUT (Look Up Table) to reproduce various color spaces accurately with smooth, artifact-free grayscale steps. Available color gamuts are DCI-P3, ITU-R BT.2020, ITU-R BT.709, SMPTE-C, EBU, and Native.

3D Look-up Table import is supported 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.

In addition, the OBM-U series has Built-in Camera Log to Linear conversion LUTs from various camera manufacturers including Log-C, C-Log / S-Log2, S-Log3 / J-Log1 and more.

The LUT-converted content can then be output to downstream devices/monitors via the SDI loop out.

Internal Video Processing Time

High Dynamic Range (HDR) applies a High Dynamic Range display gamma curve to HDR content. The OBM-U310’s maximum luminance of 850 cd/m² supports PQ EOTF (SMPTE ST 2084), Hybrid Log Gamma and S-Log3. Postium’s HDR function allows users to view both highlights and shadow details within scenes simultaneously (using our Black Stretch feature), thus resulting in more natural and realistic reproduction.

HDR Display modes provide both full-frame HDR and SDR viewing as well as simultaneous side-by-side split screen comparison.

Color Space / Dynamic Range / Gamma Comparison (Side by Side, Wipe position) allows users to compare different color spaces, gammas, HDR / SDR, camera logs, and other color settings side by side simultaneously. The comparison area can be selected and moved with a vertical wipe pattern.

Focus Assist controls the aperture level of a video signal and displays images on screen with sharpened edges to help camera focus operation.

False Color indicates the Luma (Y) level of the input image. If a certain Y level is set, the pixels with the designated Luma (Y) level are displayed with a zebra pattern or a color pattern. There are display modes – Zebra, Variable, ARRI, and Comparison.

Gamut Error Type can be observed in 3 modes. In Type 1, 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.

In Type 2, 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.

In 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.

Black Stretch increases visibility in dark areas without degradation of image quality in bright areas. This mode can be used to increase shadow detail without changing absolute black level and without affecting mid-tones.

4K HDR Waveform Monitor and Vector Scope Display modes enable users to monitor sources using the internal Waveform and Vector Scope individually or simultaneously.

The position of Waveform and Vector Scope can be moved between Top Left, Top Right, Bottom Right, and Bottom Left.

Adjustable Gamma control allows for incremental compensation between gamma correction values of 1.0 and 3.0 — thereby ensuring that the decoded image isn’t too bright (no gamma correction) or too dark (over correction).

Scan Mode allows full frame viewing of 4096 x 2160 (1.89:1) signals fed to the 1920×1080 (16:9) resolution screen. When Zero Scan mode is selected, the entire picture is displayed on the screen, maintaining a 1.89:1 ratio.

Various Frame Markers/Mattes are available on the OBM-U series, including aspect, area, and center markers. 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.

Input Signal Format Support

The OBM-U310 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. Resolutions up to 3840×2160/24,25,30,50,60p and 4096×2160/24.25.30,50,60p signals are supported.

Single Link 4K/12G

Dual Link 2-Sample Interleave (2SI) up to 2160/60p.

Quad Link 2 Sample Interleave (2SI) uses four ¼ resolution full-frame sub-images and alternates the samples every two pixels and every line rather than splitting the image into four quadrants.

Quad Link Square Division. Each link contains one quarter square of the original image.

12G-SDI (ST 2022-6) over IP is supported in the OBM-U310 via an SFP interface, which allows the use of various SFP modules. The OBM-U310 can display 12G-SDI over fiber and the 12G-SDI Single Link over IP through an integrated SFP interface (Third-Party/Sold Separately).
