TAMUZ presents IMPERIAL EAGLE series of LCD Broadcast Monitors (23/2/2009)

Exhibiting at the NAB '09 Show in Las Vegas, NV, TAMUZ presents their range of customized and unique LCD Broadcast Video Monitors.

At this event TAMUZ presents some highlights from their LCD Video Monitor product range to the American market, which are developed and manufactured in Henstedt-Ulzburg, Germany. "We making the monitor products the market needs. Our goal is, to design and manufacture monitors with the best image quality, rich features for applications, long-time product availability, at a cost effective price.“ says Erwin W. Lissy, President of TAMUZ Broadcast Monitors.

"Terms like Class-1, Grade A, Grade-1 or Reference used by marketing and sales people all over the industry classifying their monitor products confusing the customers. The standard organisations, first of all the EBU, classifies the top-of-the-line monitor as Grade-1. This specifies the monitor as a ‘measuring instrument’ for visual evaluation of image quality," comments Erwin W. Lissy, "but Grade-1 can be mis-matched with the term Grade A (what stays for ‘new device with no scratch or use’), so TAMUZ uses the term Class-1 for its high-grade high-performance monitors, which was the common term in the past CRT times!"

IMPERIAL EAGLE CLASS-1 BROADCAST MONITORS

The IMPERIAL EAGLE series, developed to reach the Class-1 (Grade-1) recommendation specifications. A further development of the last years prototype the RLM 124W HD is the first cost-effective Class-1 monitor at the market. To complete the IMPERIAL EAGLE series TAMUZ developed a bigger screen, the RLM 132W HD, containing a 32 inch FullHD LCD panel with same functionality and specification like the smaller 24 inch monitor.

The new monitors confirms the EBU t3320 Grade-1 and EBU t3325 measurement recommendations and are different to their competition. First the RLM 124W is a FullHD monitor with a 24 inch LCD panel, competition uses smaller LCD panels. Second TAMUZ still uses selected CCFL backlighting.

Next RLM 124W values for brightness, contrast and black are much better as the recommendation claims. The brightness is set for the European market to 80 cd/m2 nominal, but adjustable in the range of 70 to 100 cd/m2. For the American market the monitors are aligned to 35 fL, the range is set as 20 to 40 fL.

The RLM 124W contrast is more than 1.200:1 and the Black is darker as 0,02 fL (0.07 cd/m2) at the nominal brightness of 35 fL. The RLM 132W tops this values with a contrast range of >2.500: 1 at Blacks darker as 0,01 fL (0.025 cd/m2) at nominal brightness.

BACKLIGHT SYSTEMS CONTROLS ITSELF

To reach this specifications, TAMUZ developed for both screen sizes customized LCD panels, still using CCF lamps. The TAMUZ backlight system has a built-in controller with several sensors to stabilize the light output.

The lighting bulbs are calibrated to glow at the right color temperature. This technology produces a more homogeneous and smoother light output at the LCD front like it a huge number of LED clusters can generate. The picture quality of these panels are absolutely perfect. The displays offers wide viewing angles (>±45° HV at 50% visible brightness level) and meets the requirements of EBU compliant colors.

In the literature viewing angle is described as the angle where a contrast of 10:1 in luminance or 5:1 in chrominance is still perceptible. Data sheets names mostly high grades, like ±89° H and V. This means that the viewer looks in a side angle of 89° onto the display and sees a brightness of 0,2 fL when black is 0,02 fL and the nominal brightness level is 23 fL. Consequently this is not a very realistic data sheet value.

HD OR SD DIGITAL INPUTS

IMPERIAL EAGLE series monitors are equipped with various inputs. Three SD/HD-SDI inputs, analog HD component inputs, analog composite inputs plus analog and digital computer signal inputs as VGA and DVI are standard. The only additional options are DualLink or SD/HD/3G-SDI inputs accepting 4:2:2 and 4:4:4 signals. All inputs auto-detecting the format and standard of the input signal to process the image with lowest latency at no scaling artefacts.

DE-INTERLACER AND BLACK-LINE INSERTION

Progressive formats are always processed in their native vertical frequency. To process interlace formats several de-interlacer modes are selectable.

For special purposes an interlace simulation mode, named Black-Line Insertion, is selectable. This mode displays each field of interlaced video (odd and even) separately and blanking the corresponding second field with black lines. Using this mode the displayed image looks like a CRT image. SD and HD formats can be displayed scaled to fit the screen or 1:1 in a pixel-to-pixel mode. For displaying SD without scaling a 2:1 mode doubles the image size on screen.

MANUAL OR REMOTE OPERATION

The IMPERIAL EAGLE series is equipped with a fully loaded keyboard at the front containing turn-knobs for Brightness, Contrast, Saturation, Backlight, Zoom, Marker and a number of buttons for several functions, which allows direct adjustments and settings. Specific settings can be done within the OSD menu.

Additional the TCP/IP port at the rear can be used for operation. For this the unique MRC software was developed by TAMUZ, which allows to control hundreds of monitors in a network. The MRC software is a excellent tool to manage the monitor settings and to control the unique feature of TAMUZ monitors, the Anti-Sticking mode. This mode helps to prevent the typical LCD effect of sticking when the monitor is used for long term displaying static content, a general issue with LCD panels.

Using a standard web browser all the settings are accessible via the TCP/IP port. The keyboard also can be configured with functions individually on this way.

COLOR ALIGNMENT OF LCD VIDEO MONITORS

And last but not least, IMPERIAL EAGLE series monitors are, like most of TAMUZ monitors, equipped with AAC, the Automatic Alignment and Calibration function. A connector at the front for color analyzer probes, like Konica-Minolta CS-200, Klein Instruments K-10 or DK Technologies PM 5639, allows an easy interfacing of the probe.

The monitor itself handles the alignment by its internal processor, so no external PC or Test Generator is necessary. The AAC function generates a individual LUT to correct the colormetry and the gamma shading for the monitor to display the image at its best without banding effects. Up to four individual setups can be stored inside the monitor using the embedded web browser interface. For best and perfect calibrated performance the reset button at the front reconfigure all user settings back to the factory default.

COST EFFECTIVE CLASS-1 BROADCAST MONITORS

The IMPERIAL EAGLE series is absolutely cost effective. The basic models RLM 124W HD and RLM 132W HD are equipped with all inputs and comes with a detachable front bezel to cover a 16:9 aspect ratio. Additional a contrast filter glass can be equipped at the monitors front. The fully metal monitor housing is designed for desktop use and comes with a tiltable stand. Pricing starts at 15.000 US$.

CONFIRMING SMPTE, BT.709 and EBU 3320

The IMPERIAL EAGLE Monitors are an ideal solution for all the broadcasters and PostProductions, which needs monitors confirming the SMPTE, ITU or EBU recommendations for color critical applications. All IMPERIAL EAGLE monitors comes with its individual alignment certification assured with KonicaMinolta CS-2000 spectroradiometers.
