Need to add real-time closed captioning to your live stream? Videolinq can help in just a few steps!
Background: Videolinq is integrated with most hardware and software closed captioning publishing tools in the market. Through our partnership with leading closed captioning vendors we help traditional closed captioning systems send captions also to video on the web.
Option 1:
If you do not have closed captioning decoders skip this step and move to option 3. Customers with hardware closed captioning decoders have three ways to send closed captioning data to Videolinq –
(a) Insert captions over SDI and use video encoders that support closed captioning over the SDI signal.
(b) Send the captions data from the EEG encoding device to Videolinq (models 490-492). Contact EEG for instructions.
(c) Extract the closed captioning data from the hardware encoder with a USB cable (EEG, Link Electronics, Evertz, or Norpak) to a Windows desktop application (Telestream CaptionMaker Live or Captions; EEG iCap; 1CapApp 1Fusion; Videolinq VLcap) and send data from the desktop application to Videolinq.
Option 2:
Videolinq partners with closed captioning automation software companies. Voice Interaction is an enterprise solution to process speech to text. From the Voice Interaction dashboard select Videolinq as the target output. Use the closed captioning credentials provided in your Videolinq channel and send captions to live video.
Option 3:
Many customers do not need to purchase expensive hardware or software. If they have a one-time event or only a few events per year, it makes sense to contact a Videolinq closed captioning service provider and contract them to capture audio from your event (via phone or online), and use their equipment to send closed captioning to your Videolinq live stream. Closed captioning service providers, or “stenograph operators” as they are called, will charge about $100-150/per hour, depends on how many hours you will need their service.
In Summary:
Regardless if you use hardware, software, or vendor services, you will need to point the closed captioning data to Videolinq. When you create a channel, look for the CC tab below the preview player. Copy the details we provide and use them to send closed captioning data to your Videolinq channel. For closed captioning data to be available in real-time on your live stream you must start your RTMP encoder first. Once captions are available you will see them on the preview player, and they will appear on the Player HLS path and broadcast with the video to target social media platforms and 3rd party CDN’s.
