Case Studies

Frequently Asked Questions

We offer a comprehensive range of on-premises, virtualized and cloud encoders covering SDI, IP, RTMP/S and 4K. Our most popular encoders include: 

  • Alta: A virtualized, API-powered IP video encoder that saves time and reduces costs with next-gen workflows.
  • Encode Pro: An HD-SDI encoder trusted by major TV networks worldwide, offering low-cost, low-latency caption display.
  • Encode 4K: A native 12G encoder that allows you to flexiIbly work with broadcast, live stream and in-room spaces while encoding in 4K or HD-SDI. 
  • Falcon: A budget-friendly cloud encoder that makes it easy to add captions to RTMP/S streams.  

All our IP and SDI caption encoders are compatible with third-party automated and human captioning services. However, by using AI-Media’s LEXI automatic captions or human captions, you can build an end-to-end solution without the costly and time-consuming need to integrate third-party offerings.   

The CCMatch delay parameter allows our IP caption encoder users to match video and audio with live captions with perfect synchronization to the end viewer. CCMatch also aids in production and clipping by making sure live captions are contained completely within a segment, without overhang from programming into commercial blocks.

Our SDI and IP captioning encoders are suitable for broadcast TV in the USA (in CEA-708 Standard), or in DVB regions like the UK, Australia, and the EU (in OP-47/DVB Teletext standard.)
