Wohler Adds Features to its ‘DVM’ Video Monitors

The new features extend the units’ input/output flexibility and processing capabilities

Wohler Technologies has enhanced its DVM line of MPEG video monitors with new features that extends the units’ input/output (I/O) flexibility and processing capabilities while further simplifying monitoring operations.

Wohler’s DVM line includes the DVM-2443 monitor with four 4.3-inch screens, the 5-RU DVM-5210 system with two 10-inch screens, the 4-RU DVM-4290 unit with two 9-inch screens and the 3-RU DVM-3270 with two 7-inch screens. 

“The DVM line is distinguished for offering best-in-class performance and functionality,” said Don Bird, Wohler’s chief marketing officer. “Available in a variety of sizes and configurations, and now with the flexibility to accept inputs via both GigE and SDI inputs, the DVM line provides broadcasters with the robust confidence monitoring capabilities critical in an expanding content-distribution landscape,” he said.

Providing advanced test and measurement features for convenient at-a-glance monitoring of program content, the DVM broadcast-quality video monitors decode and display MPEG-2 and MPEG-4 signals and give users the ability to browse the PAT, PMT, and PID tables for each selected stream, Wohler says.

Each monitor now provides not only for MPEG-2 and MPEG-4 decoding via DVB-ASI streams through BNC input, but also accommodates Internet protocol television (IPTV) sources (through Gigabit Ethernet input) and HDMI sources, both with audio level meters, GPI and tally, Wohler says. Each monitor is capable of displaying in-picture level metering, video waveform and vectorscope display with classic CRT-style image calibration controls, the company says.

While the new gigabit Ethernet port on DVM monitors offers full support for IPTV video extraction, decoding, display and MPEG analysis, the systems’ SDI inputs support DVB-ASI video extraction, decoding, display and MPEG analysis, Wohler says. Precision scaling and gamma correction ensure that all video formats are scaled to the screen at the highest-possible quality. In addition to accommodating a variety of input types and formats, DVM monitors now also provide convenient Dolby D decoding capability, according to the company.
