Avenue 7450 HD Protection Switch

The 7450 module is a fail-safe, bypass protection switch for critical digital paths 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 7450 includes a passive, fail-safe path that ensures there is an output even in the event of a total power failure.

The 7450 supports HD SDI signals. Different types of signal testing (vetting) can be enabled on the 7450 and it will apply the tests automatically and independently for the Primary and Secondary inputs.

The health of a high 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 7450 to switch to the secondary input after a video freeze condition is detected in the primary input.

The switch can operate in two modes: automatic or nonresetting. In fully automatic mode, the 7450 will automatically switch back to the primary signal once it’s been restored. In the non-resetting mode, the secondary input remains routed to the output, even after the primary input has recovered.

The 7450 can be configured locally or controlled and configured remotely with Avenue 5050 Touch Screen, Avenue Tabletop Control Panel, Avenue Express Panel, or Avenue PC Software. Alarm generation, configurable user levels, module lock-out, and customizable menus are just some of the tools included in the Avenue control system.

BrightEye 30 Audio ADC and DACBrightEye 30 is a flexible audio converter that can be a two channel, bi-directional ADC and DAC, or it can be configured as a four channel converter. Perfect in desktop, post and broadcast applications, 24 bit processing ensures beautiful audio. As a bi-directional converter, two channels of analog audio are converted to AES digital audio and at the same time an AES stream is converted to two channels of analog. Alternately, the unit can be configured as a four channel AES to analog converter or a four channel analog to AES converter. BrightEye 30 also serves as a sample rate converter. For example, a digital 44.1 KHz signal from a CD player can be fed to the input and a digital AES3id, 48 KHz signal synchronous to the reference input will be output. Audio mixing, level adjustments, and channel shuffling are accessed through the BrightEye Control app. A variety of audio connectors and adapters are available for integrating BrightEye 30 to any type of system. A reference input is provided which allows digital outputs to be synchronized to either a PAL or NTSC video signal or AES reference.
BrightEye 90 HD Up/Down Cross Converter and ARC with AES AudioBrightEye 90 is a versatile up/down/cross converter or aspect ratio converter for use with analog and digital video signals. Simply set the BrightEye 90 to output your facility’s preferred or SD standard. The BrightEye 90 will accommodate whatever input you connect – analog composite, SD SDI or HD SDI. After setting the output standard, BrightEye 90 automatically converts the selected input to the correct standard for your facility. BrightEye 90 will upconvert, downconvert, cross convert, or act as an ARC, as needed. The built-in Frame Synchronizer allows you to feed asynchronous signals to the BrightEye 90. An external reference input allows genlock to a house reference. All vertical interval data and closed captioning is faithfully passed. Upconverting to High Definition Feed the analog composite or SD SDI output of a camera to a BrightEye 90 and upconvert to HD. You can take the HD signal from the BrightEye 90 into a switcher or projection system. Upconverting existing SD equipment lets you leverage the equipment you already have and operate in the HD domain. While some cameras may have firewire out, using the video output and upconverting before distribution is preferable since longer cable runs can be achieved and quality is superior. Additionally, the BrightEye 90’s reference input allows you to time the upconverted video output for use with a production switcher. Downconverting to Standard Definition BrightEye 90 will downconvert any type of HD signal and provides both an SD SDI and an analog composite output suitable for broadcast or monitoring. Cross Conversion It’s easy to convert between various HD standards, whether 720p or 1080i. Simply select the output standard you need and connect the input, that’s all there is to it. Aspect Ratio Conversion For converting between SD 4:3 and HD 16:9, BrightEye 90 has you covered. Just select the output standard you need and connect the input. Audio Processing Made Simple BrightEye 90 handles both embedded audio and discreet AES digital audio streams. Sixteen channels of embedded audio are supported in BrightEye 90. If the incoming video has embedded audio, the audio will be safely bypassed around the video processing and lipsync will be preserved. Audio mixing is available for two of the four embedded groups of audio. The AES I/O ports can be configured for eight channels of incoming audio or for eight channels of audio output. The audio mixer can be used for AES channels as well. Mixer controls are accessed through the BrightEye Control app. Monitoring for Video and Audio Audio monitoring is easy with BrightEye 90’s convenient 3.5mm mini jack. Select the audio channels you want to monitor from the front panel and plug in a headset. The HDMI connector on the rear of the unit provides a future proof monitoring interface. Plug it into most LCD monitors for confidence monitoring of your feed. Front Panel and Software Control Input selection, gain control, and test pattern controls are provided through the front panel interface. Audio presence LEDs indicate which channels are detected. Controls for crop, letterbox and pillarbox are accessed from the front panel or BrightEye Mac or PC software. Video and audio levels and the audio mixer can be adjusted through 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.
