BrightEye 91-A HD Upconverter with Analog Audio

BrightEye 91-A is an upconverter with analog composite and SD SDI inputs. Feed the analog composite or SD SDI output of a camera to a BrightEye 91-A and upconvert to HD. You can take the HD signal from the BrightEye 91-A into a switcher or projection system. Upconverting existing SD equipment lets you leverage the equipment you already have and operate in the HD domain. An external reference input allows genlock to a house reference. All vertical interval data and closed captioning is faithfully passed

Easy To Use

Upconvert Before Distribution

While some cameras may have firewire out, using the video output and upconverting before distribution is preferable since longer cable runs can be achieved and quality is superior. Additionally, the BrightEye 91-A’s reference input allows you to time the upconverted video output for use with a production switcher.

Audio Processing

BrightEye 91-A handles both embedded audio and eight analog audio inputs. Sixteen channels of embedded audio are supported in BrightEye 91-A. If the incoming video has embedded audio, the audio will be safely bypassed around the video processing and lipsync will be preserved. Audio mixing is available for two of the four embedded groups of audio.

Audio Monitoring

Audio monitoring is easy with BrightEye 91-A’s convenient 3.5mm mini jack. Just select the audio channels you want to monitor from the front panel and plug in a headset.

Monitoring with HDMI

The HDMI connector on the rear of the unit provides a future proof monitoring interface. Plug it into most LCD monitors for confidence monitoring of your feed.

Front Panel and Software Control

Input selection, gain control, and test patterns control are provided through the front panel interface. Audio presence LEDs indicate which channels are detected. Controls for crop, letterbox and pillarbox are accessed from the front panel or BrightEye Mac or PC software. Video and audio levels and the audio mixer can be adjusted through BrightEye Mac or PC software.
