Wohler RadiantGrid Partners With Nexidia on Industrys First File-Based Closed-Caption Insertion, Management, and Verification Solution

Date: 10/04/2013

Wohler Technologies today announced a partnership with audio and video search company Nexidia to offer the industry's first solution that addresses the insertion, management, and quality control of closed captions and subtitles, all in the file domain. The solution combines Wohler's RadiantGrid(TM) advanced media transformation and automation platform with Nexidia's QC(TM) tool for automated caption, video description, and language verification, enabling broadcasters to validate captions and automatically check quality after transcoding -- within one workflow, faster than real time.

 
"Our partnership with Nexidia means that for the first time, broadcasters can extract or insert caption data and validate legal compliance rapidly and efficiently all in one file-based system instead of having to rely on separate workflows," said Kirk Marple, chief software architect for Wohler RadiantGrid. "The RadiantGrid and Nexidia solutions together allow users to process massive amounts of caption and subtitle data automatically for all forms of file-based content, helping to ensure higher quality while avoiding fines."
 
The RadiantGrid solution extracts closed captioning from media sources and inserts the data back into the transcoded output file. It handles the insertion of SCC or other aligned caption data files into the VANC or VBI space, or produces new ancillary outgoing files such as SMPTE-TT or SAMI. Caption insertion and conversion can be done with or without transcoding of the video essence when using compatible video containers.
 
From there, Nexidia QC advances the process by verifying quality automatically to ensure that the right caption file appears against the right media in the right language, and that it is properly timed, all to ensure compliance. Nexidia QC can also repair misaligned caption files by comparing and adjusting the time codes of the words spoken in the audio track and the time codes in the caption file.
 
"Nexidia QC overcomes the challenge of ensuring content is being created, edited, and distributed in the right languages with the correct captions at the right times," said Drew Lanham, senior vice president and general manager of Nexidia's Media and Entertainment division. "Wohler's automated captioning technology is a perfect complement to Nexidia QC because both automate manual processes, thus reducing operating expenses and avoiding errors that can lead to fines and viewer dissatisfaction."
 
Wohler is demonstrating the joint solution in its booth, N3729, at the 2013 NAB Show. Further information about Wohler's entire product line is available online at www.wohler.com.

Cobalt Digital Targets Need for Multiple Video Feeds with openGear 9905 MPx Multi-Channel Processor Posted: 12/10/2021
Cobalt and reg; Digital Targets Need for Multiple Video Feeds with openGear and reg; 9905 MPx Multi-Channel Processor

Cobalt® Digital, an industry-leading designer and manufacturer of award-winning edge devices for live video production and master control, and a founding partner in the openGear® initiative, has answered the need for handling and processing multiple video feeds with its 9905-MPx multi-channel processor. The 9905-MPx is a next-generation advanced scaler/frame openGear synchronizer developed in direct response to customer needs for a single module that supports four independent signal paths. The card was highlighted during a press briefing held virtually on October 6th and hosted by Suzana Brady, Cobalt’s SVP Worldwide Sales & Marketing, who noted that the 9905-MPx was developed in response to customer requests for increased density, unprecedented multi-input support, and enhanced flexibility. The event also featured presentations by Dr. Ciro Noronha, EVP of Engineering, and Ryan Wallenberg, VP of Engineering. The 9905-MPx, an audio/video processor for baseband digital signals, is capable of handling up to four independent 3G signals in a single, dense, cost-effective package that provides all common broadcast processing functions without any quality compromises. The card includes individual up/down/cross conversion scalers that are specifically designed for broadcast video formats, with full ARC control suitable for conversions to/from 4:3 and 16:9 aspect ratios. The multi-path design offers discrete AES and MADI audio embedding/routing/mixing/de-embedding to any of the four processing paths. Standard 3D LUT features and available color correction accommodate SDR and HDR processing for downstream HDR systems, on a per-channel basis. The card also supports per-channel logo insertion, as well as ancillary data insertion/extraction.
