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.

The 7465 Sync Changeover Switch module can be used with Avenue’s 7400 SPG module, 5400 SPG module, or with third party sync pulse generators. In the event of a failure of the primary sync source, the 7465 changes to the secondary source.
There are three poles or sections on the 7465. One pole tests for HD SDI and SD SDI signals. The other two poles test for AES audio, Composite video, Bi-Level Sync and Tri-Level Sync. A drop in signal amplitude below a predetermined auto threshold will trigger the switch.
Multiple changeover switches can be ganged together through the control system. Depending on the application, two or more 7465s may be required to handle all signals that need to be protected.

The 7435 module is a clean and quiet protection switch for critical broadcast and satellite feeds. It switches cleanly between asynchronous sources which means it can be used live to air. The module has a full video frame synchronizer, rather than a line delay, ensuring perfect alignment of mis-timed and non-synchronous SDI sources.

The 7410 Quad Tri-Level Sync Generator is for use in high definition television and post applications. Two reference inputs allow the module to lock to any two PAL, NTSC, or 10 MHz references. The 7410 can also operate as a stand-alone master generator.
Each of the four outputs is independent and can be set to output a different Tri-Level Sync signal. The timing of each generator can be set independently. A variety of user-selectable formats are supported including: 1080i, 720p, 1080p and 1080sF. The 7410 is well suited for facilities that need the flexibility of having simultaneous 720 and 1080 Tri-Level Sync outputs.
Use this module in conjunction with the 7400 SPG/TSG for a complete reference solution.

The 7160 Serial Digital Protection DA module is a fail-safe bypass protection switch for monitoring and switching critical SD and HD paths in broadcast and satellite applications. When a fault is detected in the Primary input, the switch will activate, causing the Secondary (backup) input to be switched to the module’s distributed outputs. The switch can operate in two modes; automatic or nonresetting.
The 7160 monitors the integrity of the Primary serial digital input stream and analyzes the audio and video content. Signal health and fault detection is determined by monitoring any or all of the following parameters: Closed Caption Data, Timing Reference Signal (TRS), Black, Embedded Audio, Error Detection and Handling (EDH), CRCs, and Freeze.

The 7130 module has an HD SDI input with HD SDI, SD SDI and composite outputs, serving as both a downconverter and a distribution amplifier. If an SD SDI signal is input to the 7130, SD will pass to the outputs.
The 7130 performs automatic color space and gamma conversion to accommodate the differences between HD and SD. Output aspect ratio is selectable.
