Gefen HD-SDI to HDMI Scaler Box. Model: EXT-HDSDI-2-HDMIS

Combines SDI and HDMI Equipment for Maximum Interoperability

The HDSDI to HDMI Scaler is the newest revision of our HDSDI conversion line incorporating SD/HDSDI Single or Dual link mode conversion scaled to HDMI. Resolutions of up to 1080p are supported over the DVI link for those that want true High Definition. Supports HDSDI with embedded audio and outputs a full HDMI video and audio signal. Performance has been greatly enhanced due to Gennum's VXP Scaler onboard; allowing for new features such as: Genlock, Color & Gamma Correction, Noise Reduction, Detail Enhancement, Aspect Ratio Selection, Pattern Generator Mode, & Multiple Language Menu Support. Bottom Line? -- More performance, less cost.

SDI SDI (serial digital interface), used primarily in broadcasting, converts and transmits digital video through SDI connectors. It enables video sources to process high definition, high quality video.

How it works HD-SDI devices are connected to the HD-SDI input and HDMI devices are connected to the HDMI output. When the source, display and the Scaler are powered and connected, video signals are converted to the proper format
