Page 20 BrightEye 76 HD/SD Analog to Digital Converter With Optical Output GLOSSARY This is a brief glossary of commonly used terms associated with this product. AES/EBU The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair.
Page 21 Thus, dBm refers to power relative to 1 milliwatt, and dBu refers to voltage relative to .775V RMS. The original unit of measure was the Bel (10 times bigger), named after Alexander Graham Bell. BrightEye 76 - Page 21...
Page 22 BrightEye 76 HD/SD Analog to Digital Converter With Optical Output dBFS In Digital Audio systems, the largest numerical value that can be represented is referred to as Full Scale. No values or audio levels greater than FS can be repro- duced because they would be clipped.
Page 23 The “black & white” content of the image. Human vision had more acuity in luminance, so television systems generally devote more bandwidth to the luminance content. In component systems, the luminance is referred to as Y. BrightEye 76 - Page 23...
Page 24 BrightEye 76 HD/SD Analog to Digital Converter With Optical Output Multimode Multimode fibers have a larger diameter core (either 50 or 62.5 microns), and a correspondingly larger aperture. It is much easier to couple light energy into a multimode fiber, but internal reflections will cause multiple “modes” of the signal to propagate down the fiber.
Page 25 SDI system can carry a signal for up to 20 kilometers. Singlemode fibers require particular care in their installation due to the extremely small optical aperture that they present at splice and connection points. See also Multimode. BrightEye 76 - Page 25...
Page 26 BrightEye 76 HD/SD Analog to Digital Converter With Optical Output A Time Base Corrector is a system to reduce the Time Base Error in a signal to acceptable levels. It accomplishes this by using a FIFO (First In, First Out) memory.
