  • Avenue 8500 Composite / SD Legalizer and Video Processing Frame Sync

    The 8500 module is a composite Legalizer, Proc Amp, TBC and Frame Sync. The Legalizer is a predictive clipper which insures signal levels will not exceed those permitted in the composite domain. While the Legal setting automatically puts in values to insure signals will not exceed composite legal limits, selecting Custom allows the you to set a range of clip values.

    Noise Reducer Option

    The optional 8520 Noise Reducer removes unwanted noise and artifacts with is motion- and scene-adaptive filtering. Several forms of noise reduction are employed to ensure the best possible performance. Recursive Temporal Noise filtering includes Simple Recursive, Motion Adaptive and Motion Adaptive with Impulse Filters. Controls are provided for maximum signal-to-noise improvement and for noise threshold. These can be set manually or run in automatic mode. The combination of the 8500 module and the 8520 noise reducer is perfect for MPEG compression preprocessing and satellite or ENG feeds.

    Uncompromised Pictures

    Whether your input is standard definition SDI Digital Component, Analog Composite or Analog Component, the 8500 handles it with precision and accuracy. The SDI input is carried at full uncompressed bandwidth throughout the entire module, and EDH monitoring of the digital input alerts you to any incoming problem. Analog inputs are 4x oversampled at 12 bits of resolution. Composite signals are decoded using an adaptive comb filter. Complete control over signal levels is provided.

    Digital and Analog Outputs

    With both SD SDI and 12 bit analog inputs (composite, component, or S-Video [Y/C] formats), the 8500 is easily integrated into any hybrid facility. The 8500 simultaneously outputs both SDI digital component and 12 bit analog composite.
    Outputs are fully timed to your house reference, including the subcarrier and ScH phase of the composite output. The analog output is constructed at 8 x oversampling with 12 bits of quantizing resolution. On loss of input, the output can mute to black or freeze on the last good frame of video.

    Rock Steady TBC/Frame Synchronizer

    Input video is synchronized to your house reference by an agile TBC/Frame Synchronizer. Even noisy and jittery analog sources are faithfully tracked to provide a steady, genlocked output. Robust signal handling ensures proper time base correction for virtually any source, even a consumer VHS machine. Select the SDI input and the 8500 is a serial digital frame sync.

    Complete Proc Amp Functions

    The 8500 has a full-featured Proc Amp for adjustment of every signal parameter. Proc controls include Video and Chroma Gain, NTSC-style hue rotation, Black Balance, and pedestal. Black and White clips can be set to prevent excessive signal excursions.

    A Detail Enhancer recovers information that has been lost due to poor frequency response in upstream systems. Certain values represented in serial digital component may be illegal in the PAL or NTSC composite domains. The Predictive Composite Clipper mode identifies picture elements that would be illegal in analog composite, and limits color saturation and luminance excursions. You can be confident that the work you’re doing in digital component will look its best in composite.

    Selective (toothed) vertical blanking lets you choose to pass or strip content in the vertical interval on a line-by-line and field-by-field basis. To help optimize the settings in the Proc Amp, a Split Screen mode allows you to compare the processed output with the original material.

    Audio Options

    A four or eight channel audio sub module can be added to the main 8500 module. Either the 8415 or 8510 can be added to accommodate audio I/O, channel shuffling and mixing. The 8500 module passes embedded audio and Dolby without an audio sub module.

    Total Control

    Because the 8500 is an Avenue module, every function and parameter can be controlled from the Avenue Control System. Memory registers can be used to save the complete configuration of the module, making it easy to change instantly between different configurations. Any combination of Express Panels, Touch Screens and PCs can be used to control the 8500. The Express Panel is especially well suited for use with the 8500.

    BrightEye 90-FA HD Up/Down Cross Converter and ARC with Analog Audio and Optical OutputBrightEye 90-FA is a versatile up/down/cross converter or aspect ratio converter for use with analog and digital video signals with the addition of an optical output. Optical connectivity allows for long cable runs between buildings or in mobile applications. Simply set the BrightEye 90-FA to output your facility’s preferred HD or SD standard. The BrightEye 90-FA will accommodate whatever input you connect analog composite, SD SDI or HD SDI. After setting the output standard, BrightEye 90-FA automatically converts the selected input to the correct standard for your facility. BrightEye 90-FA will upconvert, downconvert, cross convert, or act as an ARC, as needed. The built-in Frame Synchronizer allows you to feed asynchronous signals to the BrightEye 90-FA. An external reference input allows genlock to a house reference. All vertical interval data and closed captioning is faithfully passed. Upconverting to High Definition Feed the analog composite or SD SDI output of a camera to a BrightEye 90-FA and upconvert to HD. You can take the HD signal from the BrightEye 90-FA into a switcher or projection system. Upconverting existing SD equipment lets you leverage the equipment you already have and operate in the HD domain. While some cameras may have firewire out, using the video output and upconverting before distribution is preferable since longer cable runs can be achieved and quality is superior. Additionally, the BrightEye 90-FA’s reference input allows you to time the upconverted video output for use with a production switcher. Downconverting to Standard Definition BrightEye 90-FA will downconvert any type of HD signal and provides both an SD SDI and an analog composite output suitable for broadcast or monitoring. Cross Conversion It’s easy to convert between various HD standards, whether 720p or 1080i. Simply select the output standard you need and connect the input, that’s all there is to it. Aspect Ratio Conversion For converting between SD 4:3 and HD 16:9, BrightEye 90-FA has you covered. Just select the output standard you need and connect the input. Audio Processing Made Simple BrightEye 90-FA handles both embedded audio and eight channels of analog audio. Sixteen channels of embedded audio are supported in BrightEye 90-FA.
