New Wohler iAM-MVAM Monitors Audio, Video from SDI, MPEG Transport Streams

April 12th, 2015 Posted in News Roundup By SVG Staff

Wohler Technologies (Booth SU3116) has released the new iAM-MVAM multifunction confidence monitor, available with either four 4.3-in. displays or two 7-in. displays. Able to handle inputs from multirate SDI, ASI, and IP interfaces, the iAM-MVAM monitor provides cost-effective, real-time MPEG TS, SDI, and HDMI monitoring. Handling diverse inputs, it enables operators to monitor incoming signals, internal-transport signals, and outbound distribution signals with one easy-to-use system.

“Free from codec limitations and offering robust capabilities without the costly upgrades typically associated with MPEG monitoring equipment, the iAM-MVAM series brings confidence monitoring to a new level,” said Wohler CEO Carl Dempsey. “Only the iAM-MVAM decodes and monitors MPEG transport streams carrying MPEG-2 and MPEG-4/H.264 encoded video, along with all associated data tables for complete confidence. With this remarkable capability, the iAM-MVAM opens the door to monitoring in environments in which monitoring has previously been impractical or cost-prohibitive.”

The iAM-MVAM decodes and displays MPEG-2 and MPEG-4 signals via Ethernet IP or BNC ASI inputs while giving users the ability to browse PAT, PMT, EIT, and NIT data tables for each selected stream. In addition to monitoring demodulated MPEG transport streams from any RF signal, the iAM-MVAM monitor also features dual 3G/HD/SD-SDI inputs and audio monitoring with on-screen level meters.

Building on Wohler’s MPEG range of monitors, the iAM-MVAM monitor offers such features as an intuitive touchscreen interface, decoded HDMI and SDI video output, decoded XLR audio output, a faster processor, and 1-Gbps IP input with full multicast support. Because the compact system monitors audio, video, and the transport layer simultaneously, it can replace as many as four standard pieces of equipment: the audio monitor, video monitor, transport stream decoder, and transport-stream monitor. The potential result is a reduction in both capital and operation expenditures.

A significant feature is the combination of MPEG decoding with Wohler-quality sound. The speakers and amplifiers have been designed to put out loud and clear sound that can be heard in the noisiest of equipment rooms. At the same time, Wohler has taken displays and measurements from its AMP2-16V audio/video-processing monitor to enhance the audio-monitoring function. Such features as audio bar indicators and loudness measurements are driven from multiple audio decoders including Dolby.
