The greenMachine HDR Evie is a fully featured broadcast quality real time frame by frame (dynamic) HDR to SDR converter, with an integrated frame synchronizer and 4K UHD scaler supporting formats up to 4K UHD (3840×2169).
There are two modes of operation, the greenMachine HDR Evie will function as a single 12G 4K-UHD processing channel, or four independent processing channels for SDI signals up to 3G (1080p/60)
HDR Evie is the world’s first system using proprietary advanced algorithms which automatically analyze and apply optimal corrections in real time on a frame by frame bases. This unique capability is unlike any solution today and is the perfect real time production tool for sports or any live broadcast event needing high quality real time HDR to SDR conversions.
Typically, HDR to SDR conversion is achieved using a single static correction for the entire production, which can be accomplished with our own greenMachine HDR Static solution. This is effective for fixed, predictable applications such as TV studio production. However, for more dynamically demanding and unpredictable content, such as live sports or news broadcasts, the analysis and corrections must be adapted on a frame by frame basis to cope with challenging lighting conditions, brightness levels and image composition. Until now “frame by frame” corrections were only possible by manually applying correction metadata to each frame which is then utilized during live playback; a non-real-time process, both time consuming and expensive.
The signal processing also includes dependable broadcast frame synchronization with full audio processing capability. The converter includes powerful scaling capabilities that also support a versatile Region of Interest (ROI) selection.
A bi-level SD reference signal as well as a tri-level HD reference signal can be used to synchronize the video signals. A timed reference output (SD or HD) is also provided.
Input for processing can be BNC, Fiber or HDMI. Output can also be BNC, fiber or HDMI (optional fiber SFPs ordered separately).
For 4k UHD signals the module accommodates 4x3G SDI (2SI Quad Link) or 12G SDI (Single Link) input and outputs. Signals can also be converted between single link and 2SI quad link.
Multiple additional processing features allows for adjustments of the video content, e.g. gain, hue etc. A basic test pattern generator is also available (per channel) providing the most common line & full field patterns such as color bars, pathological test pattern, full field colors etc.
The extensive audio processing capability de-embeds all audio as well as providing support four external audio inputs or outputs which individually can be configured to be analog (balanced) or digital (AES) interfaces. Multiple internal crossbars allow for extensive audio shuffling including the MADI streams. It also provides full audio processing as well as multiple adjustable user delays for audio and video.
The greenMachine titan is equipped with a fully featured local control interface with an LCD which can display image previews and audio level meters of the processed video paths in addition to the graphical user interface.
Advanced configurations, monitoring and remote control is possible via the GreenGUI application (PC or MAC)
Each greenMachine is preloaded with all the available constellations (configurations). This package has the GMC-HDR-EVIE constellation installed and licensed. You can freely load any of the available constellations (configurations) for testing and evaluation at any time, the video and audio will be watermarked until licensed. You can have multiple constellations licensed for the same machine and switching between configurations takes only a few seconds. Constellations can also be shared if you have more than one greenMachine on the network.
