Advanced HDR Conversion

Mapping between color spaces to preserve artistic intent.

Flexible HDR Solutions to meet the need of your production.

Static Conversion

Static conversion from SDR to HDR or HDR to SDR can be done via a 3D-LUT file. The 3D-LUT file maps the color space, and applies the appropriate EOTF transfer curve. This mapping is applied to all the frames of video regardless of the signal. The Cobalt 9904-UDX-4K is able to insert static LUTS with the +3DLUT-PRO and +3DLUT-4K options. Adding the +3DLUT-BBC option allows the card to come preconfigured with standard LUTs suggested by the BBC for professional broadcast.

Dynamic Conversion

Dynamic conversion takes a static LUT as a base, and allows the user to customize the look and feel of the content in real time. While an up-mapped HDR signal, or down-mapped SDR signal can be technically “legal”, conversion can be optimized for the type of content that is being produced. Cobalt digital products are compatible with both the WonderLook Pro and LiveGrade Pro software that provide full control over the transfer curve and color correction.

Dynamic Intelligent Conversion

Dynamic intelligent conversion goes beyond dynamic conversion alone by allowing an algorithm to automatically adjust the color values based on the incoming video signal. Cobalt uses Technicolor’s suite of HDR conversion tools for this task. The toolset is informed by deep learning from Technicolor’s years of Hollywood colorimetry experience. Video is analyzed frame-by-frame in real time to make adjustments more quickly than a human operator could. As lighting conditions change over the course of a broadcast, the human operator has the ability to focus on other parts of the production.

Unleash your SDR Legacy Content

Select between convenience and control

Manual

In manual mode, the Technicolor ITM SDR to HDR controls give the user the ability to adjust the ranges betwen shadows, midtones, and highlights within the content.

Preset

Preset mode provides 28 preconfigured settings differentiated by brightness and contrast. Users have many options to customize the look and feel of the content, while not having all the controls included in the manual mode.
Additional adjustments include:

  • Limiter
  • Saturation
  • Sharpness

Automatic

In auto mode, the Technicolor algorithm will adjust settings frame-by-frame in real time according to the incoming content. Fine tune adjustments can be made to the unit at the beginning of an event – but after that, the ITM process will make any adjustments due to changing lighting conditions during the event.

Bright spot analysis

Bright spot analysis and management: ability to ensure excessive bright spots are not created when converting from SDR to HDR that might detract from the creative intent of the video.

The ITM algorithm also includes advanced bright spot detection, which will isolate smaller points of light from larger bright spots within the frame. This way, when the light intensity increases from an SDR image to the brighter HDR image, lighting speculars won’t be drowned out by larger areas of light.

Noise Reduction

HDR content can get noisy, especially content shot on film. Technicolor‘s noise reduction is superior to anything currently on the market used for grading.


A static 3D-LUT typically does not have active noise reduction, this is very problematic in low light conditions, upgrading content from older cameras or cameras with small sensors or in cases with camera movement.


A powerful de-noising engine is included, as legacy SDR content will often come with a fair bit of noise. The ability to adjust the noise within the shadows and highlights helps to keep image detail while protecting against banding artifacts.

Text-to-Speech / EAS Automation

Cobalt Digital +TTS is a complete 21CVAA text-to-speech generation / audio insertion solution for embedded or discrete audio systems. +TTS is a software option available for many Cobalt card models using the 20-slot openGear® frame architecture (and available for our BBG-1000 Series standalone desktop units). Platforms utilizing existing openGear® infrastructure can be 21CVAA-ready with only an easily incorporated option feature upload to the card. For platforms not utilizing an existing openGear® infrastructure, most of our BBG-1000 Series standalone units are available with option +TTS, offering a compact rack-mounted 1RU solution easily integrated into the broadcast workflow.

+TTS interfaces with industry standard Windows Share folder systems to receive non-proprietary text, XML, or similar plain text files, and converts and inserts realistic human-voice audio into user-configured audio channels (typically an SAP channel pair intended for this playout). +TTS allows for prioritization based on the organization's discretion (for example, severe weather alerts out-prioritizing school closings). Alert tones are ducked in on the main program channel to alert the visually impaired that emergency content is to occur on the SAP channel. Alerts can be played a configurable number of times, and alerts with higher priority can interrupt current lists for breaking news. Once the interrupt message is broadcast, +TTS automatically reverts to normal audio programming. Compatible Cobalt cards and modulars offer the synergy of also providing keyed text scrolls when used in conjunction with option +KEYER.

 

  • Integrated, self-contained single-device system – no added dedicated units or baseband audio patches
  • No proprietary interfaces or API’s – queries and connects with industry standard Windows Share folders – fully automatic
  • Easy to configure IP-based folder queries with conversion from plain ASCII text or XML tags
  • Built-in user-definable dictionary to substitute plain phonetic spelling for hard-to-decipher words and proper noun phonetic emphasis
  • User-configurable folder prioritization allows higher-priority alerts to preempt lower alerts, with queued resumption of lower alert upon end of higher alert
  • English-language speech engine standard. Additional option +2L-SPAN adds Spanish-language playout.
  • Playout triggering from watched folder activity (new file) or GPI. Card GPO can be used to integrate with other devices and systems.
