Avenue 1455 4K/UHD Protection Switch
The Avenue 1455 ACO is a clean and quiet protection switch for critical 4K broadcast and satellite feeds. The 1455 uses sophisticated user-programmable parameters to detect signal failure in the primary or secondary quad-link inputs. In the event of a failure, the 1455 switches seamlessly to the backup – viewers downstream will never see the switch.
Avenue 4450 SMPTE 310M Protection Switch
The 4450 module is a fail-safe, bypass protection switch for critical SMPTE 310M signals for broadcast or satellite applications. When a fault is detected in the primary input, and the secondary input is verified as good, the switch will activate causing the secondary input to be switched to the module’s output. The 4450 includes a passive, fail-safe path that ensures there is an output even in the event of a total power failure. The health of a 310 signal is determined by monitoring digital clock lock, packet presence, and PID presence. The user can configure tests to define the minimum number of video packets and audio packets expected per second in a given service. The switch can operate in two modes: automatic or nonresetting. In fully automatic mode, the 4450 will automatically switch back to the primary signal once it’s been restored. In the nonresetting mode, the secondary input remains routed to the output, even after the primary input has recovered. Controls are easily accessed through an Avenue Control Panel, Avenue PC, GPIs, or front edge module controls. GPI inputs allow faults detected in upstream equipment to contribute to the switching logic.
Avenue 4455 ASI Protection Switch
The 4455 module is a fail-safe, bypass protection switch for critical ASI signals for broadcast or satellite applications. When a fault is detected in the primary input, and the secondary input is verified as good, the switch will activate, causing the secondary input to be switched to the module’s output.

GPI inputs allow faults detected in upstream equipment to contribute to the switching logic.
Avenue 5160 SD Protection Switch and DA
The 5160 Serial Digital Protection DA module is a fail-safe bypass protection switch for monitoring and switching critical digital paths. 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 5160 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: Timing Reference Signal (TRS), Black, Embedded Audio, Error Detection and Handling (EDH), and Freeze. A sophisticated Black detection system is employed to activate the switch in the event signal is lost. It allows the user to select not only the threshold and percentage of nonblack pixels, but also the portion of the picture to be considered. The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number of seconds for the 5160 to switch to the secondary input after a video freeze condition is detected in the primary input.
Avenue 7160 Serial Digital Protection DA
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. A sophisticated Black detection system is employed to activate the switch in the event signal is lost. It allows the user to select not only the threshold and percentage of non-black pixels, but also the portion of the picture to be considered. The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number of seconds for the 7160 to switch to the secondary input after a video freeze condition is detected in the primary input.
Avenue 7435 HD / SD Clean and Quiet Protection Switch
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. Clean and quiet switching between sources requires that they be synchronous and precisely timed to each other. The 7435 accomplishes this automatically, with integral frame synchronization of the inputs, allowing operation with both synchronous and asynchronous (wild) sources. This frame synchronization feature not only means that the output of the 7435 will always be stable and glitch-free, but it also means that in the event of a total loss of both inputs, consistently timed color black will still be output. These internal frame synchronizers can be genlocked to an external reference signal so that the output of the 7435 is synchronoA Clean Switch That’s Glitch-Free The 7435 module is a clean and quiet protection switch for critical broadcast and satellite feeds.

These internal frame synchronizers can be genlocked to an external reference signal so that the output of the 7435 is synchronous to local sources. Alternately, in teleports, headends, and other multi-service facilities, where there is no logical common reference, the 7435 will internally generate an accurate reference. The delay through the 7435 can be adjusted from one to eight frames, with independent control for the Primary and Secondary input paths. By operating with several frames of delay, the fault detection algorithms are given enough time to detect a failure in an input signal and switch to the backup before the fault has actually appeared on-air. Perfect Audio Glitch-free, quiet switching of embedded audio signals is achieved with the 7435’s precise synchronization and alignment of audio sources. Digital audio is de-embedded, and if it is linear PCM, sample rate converted, switched, and re-embedded. Encoded audio streams such as Dolby™ E are de-embedded and re-embedded but not processed in any way. PCM audio is supported with asynchronous sources, operation of encoded audio requires all sources to be synchronous, but not necessarily in time. Switch Logic When a fault is detected in the primary input to the 7435, and the secondary input is verified as good, the switch will activate, causing the secondary input to be switched to the module’s output. The 7435 includes a passive, fail-safe path that ensures there is an output even in the event of a total power failure. The module can be set to automatically switch back to the primary after the fault condition clears. If both the primary and the secondary inputs signals are faulted, no switch occurs. The health of a high definition or standard definition video signal is determined by monitoring crucial parameters in order of increasing complexity; Timing Reference Signal (TRS), or a persistent loss of digital sync is tested first. Black, Embedded Audio and Freeze are also evaluated. Each test can be configured by the user. For example, the sophisticated Black Detector includes configurable parameters for black level threshold, pixel count, and duration time. The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number of seconds for the 7435 to switch to the secondary input after a video freeze condition is detected in the primary input.

Avenue 7465 Sync Changeover Switch
The 7465 Sync Changeover Switch module can be used with Avenue’s 7400 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.
