  • Page 2: Product Overview

    As shown in the diagram below, when a standard definition serial digital video input is fed to the BrightEye 91-A, the signal enters the serial digital receiver and is frame synchronized to the reference input. Audio is disembedded and passed around the upconversion process.

  • Page 4 BrightEye 91-A HD Upconverter with Analog Audio PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES When images are converted between different formats, color spaces, and resolu- tion geometries, the need for accuracy and fidelity are extremely important. Whether upconverting from standard definition to HD formats, converting between different HD formats, or downconverting to SD, extra care must be paid to every aspect of the signal and the content of the images.
  • Page 5 The BrightEye 91-A can upconvert SD video from many different source types. As shown in the example below, the SD ingest signal from a satellite is fed to a BrightEye 91-A where it is upconverted to feed an HD Master Control Switcher. The other output can be sent to another HD destination.

BEPS6 Spider Power Supply. This powers 6 single high BrightEyes or 3 double high BrightEyes (BrightEye 90 family).
  • Page 22 BrightEye 91-A HD Upconverter with Analog Audio 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 23 BrightEye 91-A Chroma The color or chroma content of a signal, consisting of the hue and saturation of the image. See also Color Difference. Component In a component video system, the totality of the image is carried by three separate but related components. This method provides the best image fidelity with the fewest artifacts, but it requires three independent transmission paths (cables).
  • Page 24 BrightEye 91-A HD Upconverter with Analog Audio 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. The nominal operating point (roughly corre- sponding to 0 VU) must be set below FS in order to have headroom for audio peaks.
  • Page 25 BrightEye 91-A The International Electrotechnical Commission provides a wide range of worldwide standards. They have provided standardization of the AC power con- nection to products by means of an IEC line cord. The connection point uses three flat contact blades in a triangular arrangement, set in a rectangular connector.
  • Page 26 BrightEye 91-A HD Upconverter with Analog Audio 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 27 BrightEye 91-A Return Loss An idealized input or output circuit will exactly match its desired impedance (generally 75 ohms) as a purely resistive element, with no reactive (capacitive or inductive elements). In the real world we can only approach the ideal. So our real inputs and outputs will have some capacitance and inductance.
  • Page 28 BrightEye 91-A HD Upconverter with Analog Audio 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. The incoming video is written into the memory using its own jittery timing.
