Las Vegas Convention Center Upper and Lower South Halls were the main venues of new closed caption technology on display.
The 2018 NAB Show will be noted historically for several reasons. Annual visitors attending the show with specific needs and budgets tend to be a bit myopic. Most TV stations are already satisfy captioning requirements and regulations. Even so, new captioning technology makes the service better, faster, more effective and less expensive.
The FCC and most TV regulators across the world require captioning, including building it into every TV set. The original objective of captioning for the hearing impaired remains unchanged.
However, some dialog is occasionally intelligible to nearly everyone for one reason or another. Viewers are learning that captions can enhance the experience by supplementing the dialog, like reading the words while hearing a song. It helps everyone understand what they are watching.
At the 2018 NAB Show, numerous captioning solution companies displayed their solutions and services. The following recaps captioning highlights at the show by manufacturer, in alphabetical order.
The ENCO Systems 2018 NAB Show exhibit featured the latest updates to ENCO’s enCaption4 system. The updates were further strengthened through ENCO’s new patent for automated captioning, significantly raise the bar for speed and accuracy in live captioning environments.
Last fall, ENCO acquired a U.S. patent specifically applying to providing automated captioning by using speech-to-text. Patent number 7047191B2 is entitled “Method and System for Providing Automated Captioning for AV Signals.” It specifically relates to ENCO’s continued innovations for its enCaption series of automated captioning solutions.
ENCO’s popular enCaption3 solution was updated to enCaption4, which was shown at the NAB Show.
Key technical differentiators bring substantial improvements across accuracy, newsroom integration and speaker identification. enCaption4’s latest enhancements boost accuracy to 90% or higher, which far surpasses compliancy requirements in live captioning. These accuracy improvements are born through enCaption4’s advanced speech-to-text engine, which leverages breakthroughs in machine learning technology to develop a deep neural network approach to voice recognition.
New for NAB was enhanced integration to Newsroom Computer System (NRCS) MOS integration. This further improves accuracy by empowering enCaption4 to learn correct spellings from news scripts and rundowns prior to live newscasts, and without manual intervention. Additionally, enCaption4’s multi-speaker identification speaker eliminates crosstalk and other on-air confusion when multiple hosts and guests are contributing to live broadcasts. enCaption4 identifies speech from each speaker through dedicated microphones and processes each speaker separately.
The flexibility of enCaption4’s deployment options within automated production workflows also ensures optimal cost-efficiency and operational flexibility. And with support for more than 20 languages, enCaption4 stands alone as the industry’s most affordable, flexible and versatile captioning solution for dynamic, high-pressure live production environments.
Debuting at NAB was a file-based (non-live) transcription as a cloud-based captioning service that guarantees 99% accuracy. It ensures that the transcriptionist can quickly generate an accurate transcript of the audio. The resulting transcripts are made accessible from the cloud within two to eight hours, depending upon how quickly the captioned content is needed to achieve proper compliance.
Prior to the show opening, ENCO announced the enCaption4 had joined the growing NDI video over IP ecosystem. The enCaption4 systems on display in the exhibit included the new NDI capability.
EEG’s Lexi automatic captioning service is accessible through EEG encoders such as the iCap HD492 SDI encoder.
EEG joined more than 50 manufacturers at the IP Showcase at NAB 2018, organized around the new SMPTE 2110 video standard. Solutions shown by EEG were designed for completely native 2110 live captioning, as well as transitional solutions on the EEG HD492 SDI encoder to co-originate SDI VANC and 2110-40 streams based on SDI program audio.
On display in the EEG exhibit as the latest enhancement to EEG's cloud-hosted automatic live captioning platform, Lexi. Announced earlier this year, newly developed "Topic Models" empower the system to recognize topics, immerse itself in distinctive vocabulary, and observe context through the absorption of relevant web data unique to each implementation. This ground-breaking advancement enables Lexi to perform in real-time with a degree of accuracy that reaches beyond previous speech-to-text systems.
As part of Lexi’s setup process, users are now invited to select one of EEG’s developed topic models. Or, users can generate their own custom model by supplying Lexi with any combination of reference URL’s or other bulk text data specific to their subject matter or locale. As it absorbs the data, Lexi observes context of new words and names to recognize where and how they are often used.

Its unique approach to live captioning maintains integrity of content with zero restreaming. It also supports HDR.
Nearly all IP caption insertion systems are cloud-based, requiring content to be moved first to the cloud, there captioned, then re-encoded and re-streamed for delivery. This introduces significant opportunity for human and mechanical error, ultimately impacting the quality of the final content. In contrast, Telestream’s live captioning solution with Lightspeed Live Stream eliminates restreaming, instead encoding the live captions within the original stream and ensuring the best possible quality.
In addition to the new live captioning capabilities, users benefit from a true enterprise-class live streaming, encoding and packaging system. For multiscreen live encoding and packaging at scale, this advanced solution allows users can add time delay to the stream for synchronization purposes. Lightspeed Live Stream can also route captured recordings to Telestream’s Vantage Media Processing Platform for further enhancement.
