    ARC with Analog Audio User Guide Revision 2.4 SW v1.2.3 This user guide provides detailed information for using the BrightEye 90-A HD up/down/cross converter and aspect ratio converter (ARC) with analog audio output. The information is organized into the following sections: •...

  • Page 2: Product Overview

    As shown in the diagram that follows, when a high definition or standard definition serial digital video input is fed to the BrightEye 90-A, 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 BNC. BrightEye 90-A is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 100 and 230 volts, at 50 or 60 Hertz.

  • Page 6 The BrightEye 90-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 90-A where it is upconverted to feed an HD Master Control Switcher. The other output can be sent to other HD destinations.
  • Page 7 Destination House Reference HD Downconversion 2 As shown in the example below, the BrightEye 90-A can be used to downconvert material originated in HD. The BrightEye 90-A 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-A where the aspect ratio can be corrected for input to an SD switcher that requires 16:9 Letterbox.
  • Page 9 BrightEye 90-A Remote Truck/OB Van As shown below, the BrightEye 90-A accepts an SD SDI or HD SDI signal. The user sets the unit to the desired output type. The BrightEye 90-A auto-senses the input format and determines if it should up, down, or cross convert the signal, based on the user’s output format selection.
