The story of the 8500 Video Processing Frame Synchronizer begins with flexibility. This new Avenue module packs more features into a single card slot than anything we’ve ever offered before.

Total Flexibility

The flexible architecture of the 8500 makes it a multipurpose, “Do Anything,” module. Uncompromising attention to image quality and fidelity means that it can do all of these things very well.

With both SD SDI and 12 bit analog inputs (composite, component, or S-Video [Y/C] formats), the 8500 is ready to take on any signal acquisition challenge. And you can deliver that signal simultaneously in both SDI digital component and 12 bit analog composite. In between those inputs and outputs lie a rugged frame synchronizer, and a powerful proc amp. An infinitely adjustable timing system genlocks to your house reference. A choice of an optional audio processor with analog and digital I/O, and an optional Digital Noise Reducer round out the 8500 Series — it’s the total solution to signal acquisition and handling. No matter what sources you have — now, or in the future — the 8500 is ready.

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.

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 identi!es picture elements that would be illegal in analog composite, and limits color saturation and luminance excursions. You can be con!dent 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.

Digital and Analog Outputs

The 8500 has simultaneous SDI and analog composite outputs. They are fully timed to your house reference, including the subcarrier and ScH phase of the composite output. The analog output is constructed at 8x oversampling with 12 bits of quantizing resolution.

This output flexibility of the 8500 makes it easy to handle the digital transition in an existing analog facility. Both digital and analog destinations can be fed from the same source module. On loss of input, the output can mute to black or freeze on the last good frame of video.

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, Avenue Touch Screens and Avenue PC Software can be used to control the 8500. The Express Panel is especially well suited for use with the 8500.

Channel Density

Ten 8500 Video Processors (including both the Audio and DNR Options) can be accommodated by the Avenue 3RU Frame. Now that’s an effcient use of real estate!
