  • Page 2: Product Overview

    BrightEye 91 HD Upconverter with AES Audio PRODUCT OVERVIEW BrightEye 91 upconverts standard definition (SD) signals into high definition (HD) and performs format and aspect ratio conversion as needed. The built-in frame synchronizer handles any asynchronous signals fed to the unit. As video is processed, audio is processed too, since the BrightEye 91 accommodates both embedded audio and discreet AES digital audio streams.

  • Page 5 BrightEye 91 PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES When images are converted between different formats, color spaces, and resolution 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 6 BrightEye 91 HD Upconverter with AES Audio APPLICATIONS Upconversion 1 The BrightEye 91 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 where it is upconverted to feed an HD Master Control Switcher.

    BrightEye 91 REAR CONNECTORS All connections to the BrightEye 91 are made on the rear of the unit. Refer to the photo below. BrightEye 91 Rear Connectors Power Connection Connect a modular power supply to the 12 volt DC power input connection on the far left of the unit.

  • Page 8: Operation

    BrightEye 91 HD Upconverter with AES Audio Ref In This BNC accepts an analog composite video signal or Tri-Level Sync signal which is used as the genlock and timing reference for the internal Frame Synchronizer. Typically the reference signal is Color Black or Color Bars fed from a master sync generator (such as the BrightEye 55).
  • Page 9 BrightEye 91 Status Indicators The following status indicators are provided on the front panel: Embed In Illuminates when an embedded audio stream is detected on the SD SDI/Cpst In video input BNC. This applies only to SDI signals. AES In Illuminates green when a digital audio signal is detected on any of the AES digital audio BNCs.

  • Page 28 BrightEye 91 HD Upconverter with AES Audio GLOSSARY 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. The AES/EBU standard covers a wide range of sample rates and quantizations (bit depths).
  • Page 29 BrightEye 91 number of bits of resolution, or quantization, will be able to capture a signal with more detail or fidelity. Thus, a video digitizer with 12 bits of resolution will capture 4 times as much detail as one with 10 bits. Blanking The Horizontal and Vertical blanking intervals of a television signal refer to the time periods between lines and between fields.
  • Page 30 BrightEye 91 HD Upconverter with AES Audio commonly used format throughout the world, either as PAL or NTSC. It is also referred to as Encoded video. Color Difference Color Difference systems take advantage of the details of human vision. We have more acuity in our black and white vision than we do in color.
  • Page 31 BrightEye 91 can be very cost effective in transmission and routing, but can also add complexi- ty to signal handling issues because the audio content can no longer be treated independently of the video. Eye Pattern To analyze a digital bitstream, the signal can be displayed visually on an oscilloscope by triggering the horizontal timebase with a clock extracted from the stream.
  • Page 32 BrightEye 91 HD Upconverter with AES Audio The International Electrotechnical Commission provides a wide range of worldwide standards. They have provided standardization of the AC power connection 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 33 BrightEye 91 MPEG The Moving Picture Experts Group is an industry group that develops standards for the compression of moving pictures for television. Their work is an on-going effort. The understanding of image processing and information theory is constantly expanding. And the raw bandwidth of both the hardware and software used for this work is ever increasing.
  • Page 34 BrightEye 91 HD Upconverter with AES Audio Oversampling A technique to perform digital sampling at a multiple of the required sample rate. This has the advantage of raising the Nyquist Rate (the maximum frequency which can be reproduced by a given sample rate) much higher than the desired passband.
  • Page 35 BrightEye 91 video. This could refer to standard definition at 270 Mb/s, HD SDI or High Definition Serial Digital video at 1.485 Gb/s, or to the newer 3G standard of High Definition video at 2.97 Gb/s. SMPTE The Society of Motion Picture and Television Engineers is a professional organization which has done tremendous work in setting standards for both the film and television industries.
  • Page 36 BrightEye 91 HD Upconverter with AES Audio Tri-Level Sync For many, many years, television systems used composite black as a genlock reference source. This was a natural evolution from analog systems to digital implementations. With the advent of High Definition television, with even higher data rates and tighter jitter requirements, problems with this legacy genlock signal surfaced.
  • Page 37 BrightEye 91 Strictly speaking, YUV does not apply to component video. The letters refer to the Luminance (Y), and the U and V encoding axes using in the PAL composite system. Since the U axis is very close to the B-Y axis, and the V axis is very close to the R-Y axis, YUV is often used as a sort of shorthand for the more long-winded “Y/R-Y/B-Y”.
