Avenue 7550 HD Legalizer

The 7550 module is an HD Legalizer that supports high definition or standard definition digital video. When the Legalizer is enabled, the picture is processed on a pixel by pixel basis to be within legal limits for RGB requirements.
Altenatively, the Y, Cr, Cb legalizer provides controls for white clip, and black clip and chroma limiting.

Flexible Synchronization

An infinitely adjustable timing system genlocks to your house reference. The 7550 genlocks to either composite video (PAL or NTSC) or to Tri-Level Sync. The module can lock to the frame’s master reference or reference can be connected directly to the module’s external reference BNC. The serial output timing can be set anywhere within a frame of the selected input reference, which can be the module’s external BNC reference or the frame’s master timing reference.

Upon loss of signal, the 7550 provides freeze frame or black until the signal is recovered. In freeze mode, audio can be muted or passed as desired.

Uncompromised Pictures

The HD or SD 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. EDH detection, monitoring and insertion are standard on the 7550. Flags are reported through Avenue PC.

Complete Proc Amp Functions

The 7550 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.

Audio Tracking

The 8415 Audio Processing option can be added to the 7550 module. The 8415 is an eight-channel processor that has been designed to provide superior handling of embedded audio. Embedded audio is safely bypassed around the video framestore with the lip sync properly preserved.

Total Control

Every function and parameter on the 7550 and 8415 can be controlled from an Express Panel, Avenue Touch Panel, or the Avenue PC Control Application. Memory registers can be used to save the complete configuration of the module, making it easy to change instantly between different configurations.
