HD Upconverter and Cross Converter

The Ensemble-Designs 7910 module accepts an SD or HD SDI input and has four HD SDI outputs. Excellent for on-air use, the 7910 is equally at home in an HD island, in a signal ingest installation, or in a production application. Since the 7910 functions as either an Upconverter or Cross Converter, it's useful on the output of a server when material may switch between HD programming and SD commercials. It's also convenient in a dual-rate master control environment.

Sophisticated Adaptive Noise Reduction ensures delivery of a pristine output that is excellent for use in broadcast. Additionally, Picture Detail Enhancement is used to recover information that has been lost due to poor frequency response upstream. Aspect ratio conversion choices include: Letterbox, Anamorphic, Crop and Manual Zoom.

Input standard and frame rate are auto-detected. The 7910 automatically adjusts from SD to HD color space and gamma. The built-in Proc Amp provides adjustment of signal parameters with controls for Video, Chroma and Pedestal. The upconverted output is timeable with respect to the reference input. When converting to film rate (1080sF/23.98) formats, 3:2 pulldown cadence is automatically detected and backed out when present in the input.

The Avenue 7910 can be configured locally or controlled and configured remotely with Avenue Touch Screens, Express Panels, or Avenue PC Software. Alarm generation, configurable user levels, module lock out, and customizable menus are just some of the tools included in the Avenue Control System.
