Avenue 7940 SD Aspect Ratio Converter

The 7940 is an aspect ratio converter for standard definition signals. Resizing and Repositioning includes choices for: Letterbox, Anamorphic, Crop and Zoom. Proc amp controls are provided in the form of Video, Chroma and Pedestal.

The 7940 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.

Automatic Aspect Ratio Conversion

The 7940 supports AFD (Active Format Description) to mark or identify the aspect ratio of the video content. These flags are generated at the output of the module, and they are read at the input. This allows the up and downconversion process to adapt automatically to material that is already in letterbox or pillarbox form in order to produce the most appropriate conversion.

Audio Options

When an audio sub module is installed, audio is automatically delayed as needed to compensate for the video processing in the 7940. For complete audio processing, choose from three different audio sub modules. Sub modules plug onto the 7940 board and do not take up a slot in the frame.

The 8415 is an eight-channel audio sub module with AES I/O that provides management of embedded audio in the processing path, or supports audio embedding/disembedding alongside the video processing elements. Embedded audio is safely bypassed around the video frame store with the lip sync preserved. Level adjustments and channel shuffling are accessed through the built-in audio mixer. The 9670 Automatic Gain Control option can be added to the 8415. All audio processing is performed at full 24 bit resolution.

The 7610 provides carriage of up to eight channels of embedded audio through the format conversion process. Embedded audio in the input signal is delayed to match the video delay and preserve lip sync. The delayed content is reinserted in the video output. No level adjustment or channel swapping is provided.

BrightEye 90-FA HD Up/Down Cross Converter and ARC with Analog Audio and Optical OutputBrightEye 90-FA 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-FA to output your facility’s preferred HD or SD standard. The BrightEye 90-FA will accommodate whatever input you connect analog composite, SD SDI or HD SDI. After setting the output standard, BrightEye 90-FA automatically converts the selected input to the correct standard for your facility. BrightEye 90-FA 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-FA. 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-FA and upconvert to HD. You can take the HD signal from the BrightEye 90-FA 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-FA’s reference input allows you to time the upconverted video output for use with a production switcher. Downconverting to Standard Definition BrightEye 90-FA 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-FA has you covered. Just select the output standard you need and connect the input. Audio Processing Made Simple BrightEye 90-FA handles both embedded audio and eight channels of analog audio. Sixteen channels of embedded audio are supported in BrightEye 90-FA. 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 analog audio 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 analog audio as well. Mixer controls are accessed through the BrightEye Control app. Monitoring for Video and Audio Audio monitoring is easy with BrightEye 90-FA’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 patterns control 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 the BrightEye Control software. Video and audio levels and the audio mixer can be adjusted through BrightEye Control.
BrightEye 55 Genlockable Sync Generator and Test Signal GeneratorBrightEye 55 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 55 is well suited for remote trucks, desktop and fly packs. Color Black, Bars, Crosshatch, Multi-burst, and SDI Checkfield (Pathological) are just some of the signals simultaneouslyavailable on the SDI and analog composite outputs. An ID slate with user programmable text can overlay the test pattern. The cyclops feature adds a motion element to the video test signal, handy for live applications. The Tri-Level Sync output provides reference to high definition equipment, such as VTRs, disc recorders and workstations. There are a wide variety of user selectable formats including: 720p, 1080i, 1080sF, and 1080p. Format selections and other controls are accessed through the BrightEye Control app. AES 3id digital audio, analog audio and embedded audio reference outputs are provided.
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.
