BroadcastAsia2014: Wohler To Highlight Smart Signal Management, Monitoring

At BroadcastAsia2014, Wohler will showcase award-winning innovations that demonstrate the company’s expertise in smart signal management and monitoring for evolving audio and video formats, as well as its depth of experience in developing powerful and versatile IT- and IP-based solutions for highly efficient file-based media processing.

“We look forward to showcasing the latest features and capabilities of products from our baseband signal management and monitoring line, along with MPEG stream decoders and our RadiantGrid file-based processing product line,” says Craig Newbury, Vice President Sales, Wohler. “Offering innovative and award-winning solutions in each area, we provide our customers with convenient, cost-effective solutions not only for improving the efficiency and flexibility of their existing operations, but also for opening the door to new revenue-generating services.”

AMP2-E16V Series Modular Audio/Video Processing Monitor
Wohler will present its flagship AMP2-E16V audio/video processing monitor. The monitor’s feature list is the longest in the industry, yet the product is operated with one-touch simplicity. In addition to its top-quality audio system, it features simultaneous multiformat monitoring, quick program selection, instant stereo downmix, loudness monitoring, internal channel mixing including SDI re-embedding, and audio delays, plus a wide variety of meter scales and ways to view meters, video, and Dolby or SMPTE 2020 metadata.

The AMP2-E16V offers Dolby Zoom, Dolby E line position, and CRC error monitoring, as well as automatic system configuration based upon signal inputs, 32 complete system configuration presets, a complete internal help system, and Ethernet software updates. Audio processor card options facilitate easy configuration for multiple SDI, AES I/O, analog I/O, and connection to external surround systems.

AMP1-16M Dual 3G/HD/SD-SDI Audio Monitor
Wohler’s new AMP1-16M dual-input SDI audio monitor provides high-performance monitoring of embedded audio in two 3G/HD/SD-SDI streams at an attractive price point. The 1-RU system de-embeds and provides metering and monitoring of any or all of the 16 audio channels in the selected 3G/HD/SD-SDI stream. It assures 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 channel pair(s) to built-in speakers, headphones, or XLR-balanced analog outputs.

The AMP1-16M monitor features a number of convenient capabilities including remote access for setup and storage of user-defined presets via Ethernet and USB connections, along with gain adjustment/trim on individual audio channels with the ability to assign channels as left, right, or center to the internal audio system and the analog outputs. It offers both pass-through of each SDI input and a reclocked output of the selected monitored SDI stream.

MPEG DVB-ASI and IPTV Monitors
Wohler MPEG monitors decode and provide convenient at-a-glance monitoring of program content from MPEG-2/4 ASI and Ethernet IP streams, as well as 3G/HD-SDI inputs. The MPEG video monitors identify, decode, and display in high resolution both MPEG-2 and MPEG-4 signals (input via BNC or Ethernet) while giving users the ability to browse the PAT, PMT, PID, EIT, and NIT data (both ATSC and DVB tables) for each selected stream. In addition to MPEG ASI and dual-input 3G/HD-SDI with loop-through, the MPEG monitors also accommodate HDMI video and audio with level meters, GPI, and tally.

Convenient monitoring capabilities include Dolby Digital and Digital+ decoding, as well as the capacity to decode as many as 12 audio groups. In-picture level metering of up to 16 channels of audio is provided for both average and PPM (peak) levels with selectable meter scales.

Wohler will feature the MPEG-4290, a 4-RU system with two 9-inch screens; the MPEG-3270, a 3-RU system with two 7-inch screens; and the 2-RU MPEG-2443 with four individual 4.3-inch screens.

RadiantGrid Intelligent Media Transformation Platform Version 8.5
The award-winning Wohler RadiantGrid Intelligent Media Transformation Platform offers broadcasters a variety of powerful tools that boost the efficiency of file-based workflows for multiplatform media delivery. Wohler will debut version 8.5 at BroadcastAsia2014. In addition to supporting fully compliant OTT offerings for leading formats, including MPEG-DASH, HLS, and Microsoft Smooth Streaming, the latest version now includes support for HEVC outputs to further aid broadcasters and other content producers in meeting the array of target bit rates, resolutions, and frame rates necessary for today’s content delivery ecosystems.

To enable easy, cost-effective updating of closed caption data prior to delivery via traditional broadcast services or new services, the platform extracts closed captioning from media sources and inserts the captions back into the transcoded output file. A brand-new media processing engine simultaneously processes complex audio loudness correction alongside the video at unprecedented speeds.

Along with optimized video pipeline features such as anamorphic video handling, 2K/4K Ultra HD support, and higher bit depths of up to 16-bit YUV, the RadiantGrid platform has been enhanced with the RadiantGrid Detect and Correct video legalization option, which leverages Wohler’s unique RightHue algorithm to ensure comprehensive NTSC and PAL color compliance within the file-based domain.

At BroadcastAsia2014, Wohler will showcase the WohlerLoudness appliance and demonstrate its unique captioning abilities. WohlerLoudness leverages Linear Acoustic’s industry-leading AERO.file technology in a proven solution for file-based loudness correction with built-in upmix and downmix capabilities. Using file-based inspection/correction software, WohlerLoudness allows operators to identify and correct loudness issues at ingest, before they become a problem. WohlerLoudness also manages ancillary data and advanced audio processing for channel remapping and insertion of new channels into the video/audio process, and is fully compliant with ITU-R BS.1770 and EBU R128.

Cinnafilm Tachyon Wormhole Automated File-Based Retiming Solution
Cinnafilm’s Tachyon Wormhole is an automated file-based retiming solution that enables up to a ± 10% runtime adjustment while preserving not only video and audio quality, but also closed caption integrity. Based on Cinnafilm’s popular Tachyon Standards Transcoding plug-in and the Wohler RadiantGrid Intelligent Media Transformation Platform framework, Tachyon Wormhole saves time for broadcasters, allowing them to realize new revenue opportunities without materially altering the viewer’s experience of the media assets. In many cases, users can replace a great deal of expensive specialized hardware with a single server at a fraction of the cost.
