The BrightEye 73 is a dual rate 8CH audio embedder for 1.5Gbps high-definition video signals or for 270Mbps standard definition signals. There is one serial digital video input and four AES audio inputs. These four AES streams are embedded into the video stream. AES inputs are sample rate converted, allowing the use of asynchronous audio. The output of the module is an optical signal that contains the original video signal and four AES pairs. The BrightEye 73 includes an eight channel audio mixer with channel swap and shuffle capability that allows you to completely rearrange and remix audio channels. It provides precise control over audio level, with up to 12dB of gain to compensate for low level sources. All audio processing is performed at full 24-bit resolution by a digital signal processor (DSP). Delay is adjustable up to one second. The data mode operation allows Dolby E or AC-3 inputs.
