[SatNews] During the upcoming CCW 2014 in New York, Wohler will be showcasing several of their broadcasting solutions, many of interest to those involved in the SatBroadcasting™ market sectors.
Tachyon® Wormhole™ Media Retiming
The award-winning Tachyon® Wormhole™ file-based media retiming solution enables up to a plus or minus 10 percent runtime adjustment while preserving not only video and audio quality, but also closed caption integrity. Based on Cinnafilm's popular Tachyon algorithms and the Wohler RadiantGrid Intelligent Media Transformation Platform™ framework, Tachyon Wormhole saves time for content producers, allowing them to "fit and fill"—easily adjusting content to meet specific customers' length requirements without compromising the integrity or quality of audio, video, and captioning/subtitling. In many cases, this approach allows users to replace a great deal of expensive specialized hardware with a single server at a fraction of the cost. At the same time, Tachyon Wormhole not only gives time back to broadcasters and content distributors, but also allows them to realize new revenue opportunities without materially altering the viewer's experience of their media assets.
RadiantGrid Intelligent Media Transformation Platform™ Version 8.7
The award-winning version 8.7 of the 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. The platform enables fully compliant OTT offerings for leading formats, including MPEG-DASH, HLS, and Microsoft Smooth Streaming, and aids broadcasters and other content producers in meeting the array of target bit rates, resolutions, and frame rates necessary for today's content delivery ecosystem. The media processing engine parallelizes 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 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.
MPEG DVB-ASI and IPTV Monitors
Providing functionality critical for facilities migrating toward IP-oriented distribution networks, the award-winning MPEG Series 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. To meet broadcasters' increasing need for stream-based monitoring, 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 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.
AMP2-E16V Series Modular Audio/Video Processing Monitor
The AMP2-E16V monitor's feature list continues to be 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. The monitor also includes 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. A new AVB Monitoring Option card allows AVB channels to be mixed, level-adjusted, and monitored alongside AES, SDI, analog, and other input types, and in the same fashion. Further enhancements include new processing modules and newly developed software that expand the feature set and capabilities to include loudness monitoring and extended audio interfacing.
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 (both) 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.
RDM-173 Slide-Out Rackmount Video Monitor
Wohler will feature the company's RDM-173 slide-out video monitor, a 1-RU rackmount system that provides robust monitoring tools and 17-inch HD IPS (1920 x 1080) display in a design that is ideal for space-constrained environments. An optimal solution for AV conferencing and both electronic newsgathering (ENG) and OB production, as well as for integration into electronic field production (EFP) flypacks, the RDM-173 supports all formats of 3G/HD/SD-SDI, HDMI, DVI, composite, Y/C, and component video. The high-resolution display provides superb imaging video quality with viewing angles of 160°H by 140°V and both picture-in-picture (PIP) and picture-by-picture (PBP) display modes. The unit provides a 16-channel level meter on-screen, as well as waveform and vectorscope display, tally, time code, format display, and area/title safe indicators. Front-panel controls simplify operation, and intuitive on-screen menus make configuration easy.
