The greenMachine HDR STATIC Constellation is a fully featured broadcast quality HDR to SDR, SDR to HDR or cross standard HDR to HDR converter, with a frame sync and up/down/cross converters supporting formats up to 4K UHD (3840x2169). The HDR STATIC applies colour and contrast parameters equally throughout a specific piece of content, i.e. an average brightness/color range is determined across an entire program.
The HDR STATIC Constellation must be used on the greenMachine titan 4-channel HW platform. It provides either a single 12G 4K-UHD processing channel, or four independent processing channels for SDI signals up to 1080p 3Gbit/s. Modern image sensors offer significantly wider dynamic color ranges than classic TV devices can reproduce. The color ranges are defined as High Dynamic Range (HDR) and Standard Dynamic Range (SDR). SDR describes the older dynamic range in SD and HDTV standards.
With HDR there are completely new possibilities for broadcast and AV productions to provide an increased dynamic range for the viewer, including brighter highlights and more details in the dark areas of the image resulting in more brilliant and realistic images. One of the major challenges when introducing HDR with its tremendous image enhancements is to maintain good backward compatibility with existing SDR displays and receivers.
The greenMachine HDR-STATIC Constellation is a powerful tool for handling dynamic ranges and color gamuts, presenting viewers with more dynamic images than previously seen, even without an up-to-date HDR display. It provides conversion functionality, simultaneously combining it with a static (real time) tone mapping algorithm. This application allows the user to carry out up-, downand cross-conversions between common input and output curves including Gamma, PQ, HLG and slog3 and conversions between full and narrow ranges through appropriate static tone mapping. Conversion between color spaces including Rec. 601, Rec. 709 and Rec. 2020 are also possible. HDR content can also be displayed, by contrast compression, on non HDR-capable TV monitors thus producing a high level of HDR-enhanced image quality for all possible display types.
The Custom LUT feature allows users to upload up to 20 user LUTs to obtain the desired contrast, color, saturation, black and white levels.

This greenMachine HDR STATIC constellation also includes spatial Up, Down and Cross conversions up to 4K UHD, audio processing and shuffling, color correction, timing adjustment, Meta Data processing and the Nova controller which enables the greenMachine to be remotely controlled and monitored via third party master control software. CustomControl is also included providing simplified customised screen panels offering direct access to user selected parameters.
