OBM-L Series Overview
The Postium OBM-L180 is designed as a full-featured entry-level HD/SD broadcast and motion picture production monitor.
The OBM-L180 accepts up to 1080 60P signals displayed at native 1920×1080 resolution and is equipped with a single 3G/HD-SDI input and output interface as well as an HDMI 1.3a input.
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.
High Dynamic Range (HDR) Emulation applies a High Dynamic Range display gamma curve to HDR content. The OBM-L Series 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, thus resulting in more natural and realistic reproduction.
SDR/HDR Display modes provide both full-frame HDR and SDR viewing as well as simultaneous side-by-side split screen comparison.
In addition, the OBM-L 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. Plus, custom 3D LUTs (32^³ and 64^³ cube files) can be imported for accurate and consistent color matching between different displays and for DIT previews of customized ‘looks’ that have been created by 3rd party color-grading applications.
The LUT-converted content can then be output to downstream devices/monitors via the SDI loop out.
Color Space / Dynamic Range 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 highlighted to assist camera focus.
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.
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.
When HDR mode is set on, HDR Waveform is displayed on screen.
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).
In-Monitor Display (IMD) Function allows image source names and tally information to be displayed on the screen, with an external remote function via Ethernet. TSL system protocol is supported. The color of the source name and tally color is selectable among White, Red, Green, Blue, Yellow, Cyan, Magenta.
Various Frame Markers/Mattes are available on the OBM-L 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.
Remote Control via Ethernet allows all OBM-L Series monitors to be connected via Ethernet and controlled remotely on the network. The System Date Copy Function allows users to save the monitor configuration and adjustment settings 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 or many.
