Peak/VU indicators illuminate red when the audio level on that channel exceeds the headroom level set by the user (with the Peak Indicator control.) Additionally, the VU indicator illuminates orange when...

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 12 BrightEye 24 SDI to Analog Converter and Disembedder 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 13 BrightEye 24 Error Detection and Handling is a method to verify proper reception of an SDI or HD-SDI signal at the destination. The originating device inserts a data packet in the vertical interval of the SDI signal and every line of the HD signal which contains a checksum of the entire video frame.
- Page 14 BrightEye 24 SDI to Analog Converter and Disembedder Interlace Human vision can be fooled to see motion by present a series of images, each with a small change relative to the previous image. In order to eliminate the flicker, our eyes need to see more than 30 images per second. This is accomplished in television systems by dividing the lines that make up each video frame (which run at 25 or 30 frames per second) into two fields.
- Page 15 BrightEye 24 NTSC The color television encoding system used in North America was originally defined by the National Television Standards Committee. This American standard has also been adopted by Canada, Mexico, Japan, Korea, and Taiwan. (This standard is referred to disparagingly as Never Twice Same Color.)
- Page 16 BrightEye 24 SDI to Analog Converter and Disembedder RGB systems carry the totality of the picture information as independent Red, Green, and Blue signals. Television is an additive color system, where all three components add to produce white. Because the luminance (or detail) information is carried partially in each of the RGB channels, all three must be carried at full bandwidth in order to faithfully reproduce an image.
- Page 17 BrightEye 24 Time Base Error Time base error is present when there is excessive jitter or uncertainty in the line to line output timing of a video signal. This is commonly associated with playback from video tape recorders, and is particularly severe with consumer type hetero- dyne systems like VHS.
