  • Avenue 4500 ASI and SMPTE 310M Converter and MPEG Transport Processor

    The 4500 MPEG Transport Stream Processor works with both DVB-ASI and SMPTE 310M bitstreams. It provides stream content analysis with support for both Priority 1 and Priority 2 test protocols of the ETR 290 DVB measurement guidelines. As a converter, it can translate ASI to 310M or 310M to ASI. Using the reference input, the output bitstream can be synchronized to a video or 10 MHz reference signal.

    The 4500 module is useful in broadcast and transmission applications. The built-in transport stream analyzer detects whether the input constitutes a valid signal by checking for PAT, PMT, and PID packets. In addition to the ETR 290 test protocols, analysis and data rate for elemental streams is performed. Alarms can be generated via SNMP, Avenue PC, and contact closure outputs.

    The 4500 acts as a Time Base Corrector to remove jitter and adjust transport streams to the precise, desired bit rate. The reference input to the 4500 allows the use of either analog video or a 10 Mhz signal to synchronize the output of the module. This is of particular importance in broadcast applications where the quality of the symbol clock – both jitter and accuracy – bears directly on the modulation process.

    Reference to the 4500 can be supplied from an Avenue 7400 or 9400 SPG with GPS Option in order to provide the ultimate clock accuracy. In this configuration, the 4500 is an ideal solution to frequency coordination for multi-transmitter systems like Single Frequency Networks (SFN) and mobile/handheld transmission services.

    A CRC and Data Checksum packet can be seamlessly inserted into the stream by the 4500 to provide data path integrity testing at downstream points. Monitoring of these special packets can be performed by a second 4500 or an Avenue 4450, 4455, or 7455 ASI/310 Protection Switch. Data Integrity history is carried forward through the system to facilitate fault finding. These CRC packets provide an unequivocal test of data integrity on a transmission link by transmission link basis. This is easier, more accurate, and less expensive than using a complex MPEG analysis tool to troubleshoot a data path problem.

    Set the output of the 4500 module to the desired signal type, either ASI or 310M. The module auto senses what type of signal is on the input and converts as needed. Advanced configuration in the Avenue Control System allows choosing which services on the input are passed on to the output.

    The 4500 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.

    For critical signals paths, consider building a redundant system using a 4450, 4455 or 7455 bypass protection switch.

    BrightEye NXT 950 4 Channel SDI Frame Sync & U/D/CThe BrightEye NXT 950 Frame Synchronizer packs a lot of features in a tiny package. Frame Synchronization and Format Conversion, with 16 channels of embedded Audio. The NXT 950 has four independent frame synchronizers. Each supports automatic input format detection and conversion to desired output format. Adjust video and chroma gains with the built-in Proc Amp. Color Correct to compensate for input material or to match projectors and monitors. Adjust levels and swap/mix channels in Embedded Audio. Even embedded surround sound (Dolby, AC-3) is synchronized from input to output. Control the Frame Syncs and monitor each channel’s input and output from the front panel, or through the interactive Web interface. Rackmount up to three NXT 950s in 1RU for the ultimate processing density.
    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.

    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.
