NAB 2012: Wohler To Unveil New MPEG Video Monitors

Wohler Technologies has expanded the company’s DVM line with three new MPEG video monitors that increase broadcasters’ flexibility in designing and implementing the monitoring solutions their operations require. The new monitors will be shown for the first time at NAB. Wohler will also show the AMP1-16M Dual-Input 16 Channel SDI Audio Monitor, RMQ-230 Quad Split Video Monitor, HDCC Series Captioning/Subtitling for OpenGear, and RMV16 Multiviewer.

DVM MPEG Video Monitors
Following the recent release of the DVM-2443 MPEG/ASI monitor with four 4.3-inch screens, Wohler will now also offer the new DVM-5210, a 5-RU system with two 10-inch screens; the DVM-4290, a 4-RU unit with two, 9-inch screens; and the DVM-3270, a 3-RU system with two, 7-inch screens. All of the DVM MPEG monitors provide advanced test and measurement features for convenient at-a-glance monitoring of program content from 3G/HD/SD-SDI inputs and MPEG-2/4 ASI streams.

“Our growing DVM line offers best-in-class performance and functionality that previously were available to broadcasters only in more expensive solutions,” said Don Bird, chief marketing officer at Wohler. “As we continue to roll out additional DVM monitors in a variety of sizes and configurations, we’re providing broadcasters with expanded capabilities in confidence monitoring to keep pace with the broadening content distribution landscape.”

DVM series broadcast-quality video monitors decode and display MPEG-2 and MPEG-4 signals via BNC input while giving users the ability to browse the PAT, PMT, and PID tables for each selected stream. In addition to MPEG ASI and dual-input 3G/HD/SD-SDI with loop-thru, the DVM monitors also accommodate DVI, component, and composite video with audio level meters, GPI, and tally. Each monitor is capable of displaying in-picture audio level metering, video waveform, and vectorscope with classic CRT-style image calibration controls. Using precision scaling and gamma correction to produce the best image possible, each DVM monitor scales all video formats to fit on screen at the highest quality.

AMP1-16M Dual-Input 16 Channel SDI Audio Monitor
Wohler will debut a new dual input SDI audio monitor that offers high-performance monitoring of embedded audio in 3G/HD or SD-SDI streams. The 1RU unit de-embeds and provides metering and monitoring of any or all of the 16 audio channels in the selected 3G/HD or SD-SDI stream. It offers intuitive operation and clear display of levels and other critical information using bright 2.4-inch LED-backlit LCD displays, enabling one-touch monitoring and summing of any selected pair(s) via built-in speakers, headphones, or XLR balanced outputs. The monitor offers a number of capabilities including remote access for setup and storage of user-defined presets via Ethernet and USB connections; gain adjustment/trim on individual audio channels, with the ability to assign channels to either or both outputs as well as select or deselect channel pairs; pass-through of both SDI inputs; and re-clocked output of the selected monitored SDI stream.

RMQ-230 Quad Split Video Monitor
Also on display at the 2012 NAB Show will be the new RMQ-230 quad split video monitor, which allows users to watch video and monitoring data in up to four display windows on a single 23-inch 1920×1080 LED backlight screen. RMQ-230 series monitors accept 3G/HD/SD-SDI, analog composite, and HDMI inputs in varying configurations tailored for different monitoring applications and price points. In addition to allowing broadcasters to mix and match video input formats on a single screen, RMQ-230 monitors can display waveform and vectorscope while also providing audio de-embedding, audio metering of up to eight channels, UMD, timecode, and various markers. While the new Wohler LCD monitor can display video and monitoring features in four uniform areas, broadcasters also can configure the system as a single full screen or with one large and three smaller windows.

HDCC Series Captioning/Subtitling for OpenGear
Wohler will introduce two versions of its popular HDCC Series captioning/subtitling cards for use with the openGear 2RU modular frame and associated Dashboard control software. The first is a full-featured model that provides all the capabilities of the current HDCC Series dual-channel captioning/subtitling card within the openGear form factor. The card boasts a range of capabilities including complete, independent dual channel operation for encoding, decoding, and monitoring of captions with versions to support every major global standard including CEA-608, CEA-708, WST, OP-47, and ARIB B37, as well as encoding and decoding of multiple GPI cues and 3G support. The second HDCC version is a single-channel encoding solution designed to complement the new Ross Nielsen Watermarks Encoder (NWE-3G). This single-channel openGear HDCC Series card provides CEA-608/708 captioning functionality that gives users of legacy Nielsen systems a way to transition smoothly to the new Ross NWE-3G system while maintaining full closed-captioning capabilities.

RMV16 Multiviewer
Wohler’s RMV16 multiviewer gives control rooms and other mission-critical areas the power and flexibility to drive up to 16 separate monitoring windows to a common flat-panel display. The RMV16′s mix-and-match design allows broadcasters to select the number of inputs and outputs they require and to display these sources combined with waveform, vectorscope, de-embedding and metering of up to eight audio channels, UMD, timecode and insertion/display of both clock and still images. The multiviewer accepts inputs including analog composite video, component, SD-SDI, HD-SDI, and even 3G, and can provide outputs in VGA, DVI, and HDMI formats. Each screen layout and configuration can be stored to a given preset, allowing for later recall of wall configuration changes set through the system’s intuitive GUI. Dual power supplies and air-cooling help to ensure reliable performance.
