Wohler Introduces the DVM-2443 MPEG Video Monitor 

Wohler Technologies unveiled the new DVM-2443 MPEG video monitor, a cost-effective four-screen monitoring system that offers broadcasters advanced test and measurement features in a stand-alone 2-RU configuration. The DVM-2443 video monitor incorporates four 4.3-inch 16:9 ratio LED backlit displays for flexible and convenient at-a-glance monitoring of program content from 3G/HD/SD-SDI inputs and MPEG-2/4 ASI streams, as well as metadata, waveform, and vectorscope overlays, and audio-level meters.

"Advanced features and capabilities previously available only with more expensive products will be bundled standard with our cost-effective, best-in-class DVM product line as we continue to expand the DVM range," said Jeff McNall, Wohler's product line manager for audio and video products. "Our new DVM-2443 monitor goes beyond conventional monitoring by supporting 3G/HD/SD-SDI inputs as well as MPEG-2 and MPEG-4 ASI streams and associated metadata."

The new Wohler DVM-2443 video monitor accepts two 3G/HD/SD-SDI loop-through inputs, as well as composite video, component video, DVI-I, and analog audio stereo inputs. The 2RU unit outputs audio via built-in speakers and a headphone jack, and a clever and intuitive menu allows each volume knob to double as a menu-selector scroll-wheel — giving operators a faster selection process than simple up or down arrows.

As DVM-2443 users monitor up to four video inputs, they can queue up waveform or vectorscope displays that occupy either an eighth of the screen or the full screen. The monitor displays crucial program information, timecode, format, and visual markers along with video program content, and users have the option of switching any screen from video to the related program ID (PID) table. The DVM-2443 provides 16 on-screen audio-level meters de-embedded from the SDI signal and also performs AAC audio decoding.

Wohler RMV16 Multiviewer Enables Flexible, Cost-Effective Monitor Wall Implementation

Wohler Technologies announced the IBC debut of the RMV16 multiviewer, which gives control rooms and other mission- critical areas the power and flexibility to drive up to 16 separate 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, audio de-embedding, audio metering of up to eight channels, UMD, and timecode, along with still image and clock insertion.

"Wohler is pleased to announce the newest offering in our popular line of high-quality video monitoring products," said Jeff McNall, Wohler's product line manager for audio and video. "Broadcasters are increasingly investing in affordable high-quality, large- format flat-panel displays to optimize space and reduce per-screen costs. The RMV16 is a simple yet flexible solution that supports this cost-saving approach while giving users the ability to create and store multiple screen configurations with a variety of formats and resolutions, all from a single Ethernet-connected PC interface."

The new Wohler 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.

The RMV16 supports a 1920 x 1200 maximum resolution output display and 50-Hz or 60-Hz input signal applications. With no restriction on signal source grouping, the operator can send any signal to any display at any scale. In addition to driving video sources to the display, the multiviewer provides monitoring of embedded audio and external analog audio, including as many as eight audio meters per window. Users can easily configure video and audio alarms through the multiviewer's GUI.

Wohler's RMV16 is available in either a 1RU chassis that supports four cards providing for up to 16 inputs and 8 outputs or a 3RU chassis that supports 16 cards providing for up to 64 inputs and 32 outputs, allowing broadcasters to select the model that accommodates their budgets as well as their I/O needs.

New Wohler RMQ-230 Quad Split Monitor Enables Flexible Display of Video Inputs, Monitoring Features

Wohler Technologies announced the release of 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 1920x1080 LED backlight screen.

"The RMQ-230 gives broadcasters four screens in one cost-effective monitor, and enables further savings and convenience by giving users the flexibility to view not only program content and monitoring tools, but also PC content on one display," said Jeff McNall, Wohler's product line manager for audio and video. "In addition to providing unusually robust audio-level metering capabilities, the RMQ-230 supports signal levels up to 3G, a feature not normally found in quad-split displays for this size category."

RMQ-230 series monitors accept 3G/HD/SD-SDI, analog composite, and HDMI inputs in varying configurations tailored for different monitoring applications. 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, the latter being ideal for simultaneous PC workstation screen and audio/video confidence monitoring usage. The monitor's loop-through connections help to save space in tight quarters.
