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.

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 71 & 71-F HD/SD 8 Channel Analog Audio Embedder/DisembedderThe BrightEye 71 is a dual rate eight channel analog audio embedder or disembedder for 1.5Gb/s high definition video signals or for 270Mb/s standard definition signals. The analog audio ports automatically configure as inputs or outputs depending if the module is configured as mux or demux. When configured as a multiplexer, the BrightEye 71 has one serial digital video input and eight analog audio inputs. The audio streams are embedded into the video stream. The output of the module is a digital stream that contains the original video and audio signals. When configured as a demultiplexer, audio signals present in the incoming video signal are extracted and delivered as analog audio. The BrightEye 71 includes an eight channel audio mixer with channel swap and shuffle capability that allows you to completely re-arrange and re-mix audio channels. It provides precise control over audio level, with up to 12 dB of gain to compensate for low level sources. All audio processing is performed at full 24 bit resolution by a digital signal processor (DSP). Delay is adjustable up to one second. Order the BrightEye 71-F if you need an optical output.
BrightEye 90-F HD Up/Down Cross Converter and ARC with AES Audio and Optical OutputBrightEye 90-F is a versatile up/down/cross converter or aspect ratio converter for use with analog and digital video signals with the addition of an optical output. Optical connectivity allows for long cable runs between buildings or in mobile applications. Simply set the BrightEye 90-F to output your facility’s preferred HD or SD standard. The BrightEye 90-F will accommodate whatever input you connect analog composite, SD SDI or HD SDI. After setting the output standard, BrightEye 90-F automatically converts the selected input to the correct standard for your facility. BrightEye 90-F 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-F. 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-Fand upconvert to HD. You can take the HD signal from the BrightEye 90-F 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-F’s reference input allows you to time the upconverted video output for use with a production switcher. Downconverting to Standard Definition BrightEye 90-F 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-F has you covered. Just select the output standard you need and connect the input. Audio Processing Made Simple BrightEye 90-F handles both embedded audio and discreet AES digital audio streams. Sixteen channels of embedded audio are supported in BrightEye 90-F. 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 BrightEye Control Software. Monitoring for Video and Audio Audio monitoring is easy with BrightEye 90-F’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. Crop, letterbox and pillarbox can all be adjusted from the front panel. For more control, BrightEye Control Software provides controls for proc, audio mixing, and other advanced controls.
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.
