  • 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. The 4455 includes a passive, fail-safe path that ensures there is an output even in the event of a total power failure.

    The health of an ASI 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 4455 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 Software, GPIs, or front edge module controls. GPI inputs allow faults detected in upstream equipment to contribute to the switching logic.

    BrightEye 57 3G/HD/SD/Analog Test Signal and Sync Pulse GeneratorBrightEye 57 is a genlockable sync generator and test signal generator that can be used as either a slave or master reference generator. It can lock to house reference or it can lock to its own internal precision standard. BrightEye 57 is well suited for remote trucks, post, helicopters and fly packs. 1.5 Gb/s HD, 3 Gb/s HD or SD SDI test signals or black with embedder is output on the SDI BNCs. Composite, Tri-Level Sync and AES digital audio outputs are also provided. There are three user Programmable Outputs that are selectable between AES, LTC, Word clock or 6 Hz Pulse. Analog audio and AES outputs provide tone or silence. Color Black, Bars, Crosshatch, Multi-burst, and SDI Checkfield (Pathogenic) are just some of the signals simultaneously available on the SDI and analog composite outputs. The Cyclops feature adds a motion element to the selected video test signal. An ID slate with user programmable text can overlay the test pattern. The internal Time Code Generator feeds DVITC on the SDI outputs and VITC on the composite outputs, Time Code can also be selected in LTC form on the programmable Aux outputs. In addition to the standard suite of test patterns, users can create custom test patterns on a computer. Using BrightEye Pattern Generator software, simply transfer test patterns to the included Secure Digital flash memory card and then insert the memory card into the front of the BrightEye 57. Test patterns can include motion. File formats supported: .tga, .wav, .mp3, .wma. Many controls can be adjusted through the intuitive front panel. The BrightEye Control app provides a complete user interface for all adjustments and controls. For facilities and manufacturers using 3 Gb/s video, BrightEye units can be combined to form a complete 3G signal chain. The BrightEye 57 test signal generator’s 3G output can be distributed through the BrightEye 43 3G distribution amplifier or the BrightEye 46 and BrightEye 48 E/O 3G fiber optical transmitter/receiver set.
    BrightEye 16 SDI to Analog Video Converter with Frame Sync/Genlock and Audio DisembedderBrightEye 16 is a digital to analog video converter with a timeable output. It’s perfect for feeding analog switchers and routers, where signal timing is required. It’s also a disembedder and provides four analog audio outputs. With timing controls, proc adjustments, and a built-in audio mixer, BrightEye 16 provides a complete solution for digital to analog conversion. BrightEye 16 has an SDI video input and a reference input. The input signal is converted to analog composite and synchronized (genlocked) to the reference signal. The analog composite output is fully timed with respect to the reference, including ScH phase. Audio is disembedded with 24 bit precision and converted to analog. Basic controls are accessed on the front panel. Use the BrightEye Control app to access video proc controls and the built-in audio mixer. The vertical interval can be passed or blanked. VU indication is provided on the front panel and BrightEye Control.
    BrightEye 20 Analog and Digital Audio Embedder or DisembedderBrightEye 20 is a versatile audio Mux/Demux. With SDI video I/O, and both analog and AES I/O, it is field configurable for embedding or disembedding. When configured as a multiplexer, BrightEye 20 has one serial digital video input and two AES digital audio inputs. Alternately, the 4 channel analog audio input can be used. The audio is embedded into the 601 video stream. The output is a serial digital video stream that contains the original video plus the two AES streams or four analog audio channels. When configured as a demultiplexer, audio signals present in the incoming serial digital video signal are extracted and delivered simultaneously as two AES digital audio streams and as four analog audio channels. Audio mixing, level adjustments, and channel shuffling can be applied to both the multiplexer and demultiplexer modes, and are accessed through the BrightEye Control app. Audio group selection is also made through BrightEye Control. A variety of audio connectors and adapters are available for integrating BrightEye 20 to any type of system.
    BrightEye 24 SDI to Analog Converter and DisembedderBrightEye 24 is both a disembedder (demultiplexer) and a digital to analog video converter. The incoming serial digital video signal is converted to an analog composite output. Audio signals present in the incoming digital video signal are extracted and delivered as four channels of analog audio. Audio mixing, level adjustments, and channel shuffling are accessed through the BrightEye Control app. Audio group selection is also made through BrightEye Control. A variety of audio connectors and adapters are available for integrating BrightEye 24 to any type of system. Use BrightEye 24 in desktop and broadcast applications.
