  • Page 1 ARC with AES Audio and Optical Output Revision 2.4 SW v1.2.3 This user guide provides detailed information for using the BrightEye 90-F HD up/down/cross converter and aspect ratio converter (ARC) with AES audio and optical output. The information is organized into the following sections: •...

  • Page 2: Product Overview

    As shown in the diagrams that follow, when a high definition or standard definition serial digital video input is fed to the BrightEye 90-F, the signal enters the serial digital receiver and is frame synchronized to the reference input. Audio is disembedded and passed around the video processing.
  • Page 3 SDI outputs. When SD SDI is present on the SDI outputs, composite video will be present on the composite output BNC. BrightEye 90-F is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 90 and 230 volts, at 50 or 60 Hertz.

  • Page 5 5) The final output signal is built from this intermediate progressive workspace, which is the most uncompromised version of the image possible. It provides the best possible starting point from which to create the final output signal. BrightEye 90-F - Page 5...
  • Page 6 The BrightEye 90-F 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 90-F where it is upconverted to feed an HD Master Control Switcher. The optical output can be sent to the fiber backhaul.
  • Page 7 Fiber Backhaul House Reference HD Downconversion 2 As shown in the example below, the BrightEye 90-F can be used to downconvert material originated in HD. The BrightEye 90-F can output signals to feed a server, video monitor and HDMI display simultaneously.
  • Page 8 SD input signal to a different aspect ratio. In the example below, the input from an SD camera with 16:9 lenses can feed an anamorphic signal to the BrightEye 90-F where the aspect ratio can be corrected for input to an SD switcher that requires 16:9 Letterbox.
  • Page 9 BrightEye 90-F Remote Truck/OB Van As shown below, the BrightEye 90-F accepts an SD SDI or HD SDI signal. The user sets the unit to the desired output type. The BrightEye 90-F auto-senses the input format and deter- mines if it should up, down, or cross convert the signal, based on the user’s output format selection.
