Distributors and Cinema Exhibitors can gain a great competitive advantage with HTM technology. Learn more now!

HTM | Hybrid Tone Mapping:


Transport and Decoding System for Cinema Displays with different Characteristics

Today we use different Digital Cinema Packages (DCP) for Standard Dynamic Range (SDR), Extended Dynamic Range (EDR) and High Dynamic Range (HDR) cinema displays. This is an issue for versioning and distribution companies as limited timing is generally available prior to worldwide release. We are quickly moving toward a time when the HDR version of a production will become the primary delivery requirement while the SDR version will be needed for the balance of the screens. 


We have developed the MultiDynamic Digital Cinema Package (MD DCP), a unique DCP that can transport all versions within the same SMPTE-structured DCP. The HDR/EDR/SDR versions are played from different Composition Play Lists (CPL) based on the display’s capabilities. We have also developed a color mapping tool (MultiDynamic-map, MDmap) that adapts the signal to each display's dynamic capabilities.


MD DCPs are fully compatible with all types of projection systems and LED cinema screens.

Optimized Storage 

Two or more versions – SDR (Standard Dynamic Range) and HDR (High Dynamic Range).

A Singular Smart Solution

Our solution provides one DCP that is entirely compatible with projection system and LED display capabilities. 

Full Artistic Control 

HTM technology allows to combine an automatic adaption of the signal with the settings done by the color grader at the postproduction stage.

More Flexibility 

MD DCP paves the way to a flexible and staggered migration of movie theaters toward HDR technology. 

"MD DCP offers a unique opportunity to assemble all versions of the same film on just one medium, one single DCP, without any significative increase in file size compared to a regular DCI DCP. This enhancement represents a great competitive advantage for both distributors and exhibitors. With this new, smart DCP, they can adopt HDR solutions like EclairColor HDR while simplifying the supply chain in a bold way. Without altering any aspect of the artistic choices made by the filmmaker or the director of photography, HDR and SDR versions are merged in an intelligent manner on one DCP. Movies can be projected from a single media fully compatible with the SMPTE standard and fit any type of existing display technology.”

Cédric Lejeune

“Thanks to Eclair's talented engineers, we are launching a singular smart solution that provides one DCP that is entirely compatible with projection system and LED display capabilities. The number of DCPs required is therefore greatly reduced. The HTM technology will facilitate the adoption of the HDR image in movie theaters. It can be used with both digital cinema projection systems installed at the beginning of the digital transition all the way to EclairColor-certified high contrast projection systems and EclairColor-certified high contrast LED Cinema Screens. With such flexibility, MD DCP paves the way to a flexible and staggered migration of movie theaters toward HDR technology.”
