Frequently Asked Questions

ALTA RTMP is designed for time-limited streaming events like conferences or corporate town halls. It’s compatible with all major live streaming platforms, including Facebook Live, YouTube Live Events, Twitch, UStream, and many more. To use ALTA RTMP, you must be able to output an RTMP or RTMPS stream from a streaming media encoder.

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.)

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.   

Yes, LEXI Text automatic captions work with our entire suite of encoders. This includes: 

  • 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 fLEXIbly work with broadcast, live stream and in-room spaces while encoding in 4K or HD-SDI. 
  • ALTA RTMP: A budget-friendly cloud encoder that makes it easy to add captions to RTMP/S streams.  

The iCap Cloud Network offers a range of benefits, including: 

  • Higher bandwidth audio to captioners for increased clarity and word accuracy 
  • Enhanced security, with all iCap connections encrypted and authenticated 
  • Seamless transitioning from hardware-driven to software-controlled environments

  • 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.

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

ALTA RTMP only works with RTMP (Real Time Messaging Protocol) input (livestreams), while the physical encoders work with SDI input. A physical encoder can have some additional benefits, like captioning closer to real-time, which can help for in-venue options like CaptionCast or open caption outputs.

With our LEXI Translate product, yes. However, you need to make sure your workflow can accommodate multiple languages.

A ALTA RTMP instance would need to be created for each additional livestream.

ALTA RTMP is compatible with any platform supporting RTMP-embedded captions, including Facebook Live, YouTube Live, Wowza, Vimeo, Twitch and Vbrick.

The file format ALTA RTMP produces post-stream is a .scc file. You can locate the .scc file via the ‘Download Captions’ tab within your ALTA RTMP instance. Once you’ve downloaded the .scc file, you can then use our Caption File Converter product (via your EEG Cloud Account) to convert the .scc file to the following file format types:
  • WebVTT
  • Timed Text Markup Language (TTML)
  • SubRip (.srt)
  • Scenarist SCC
  • SAMI (.smi)
  • ECF
  • EBU Subtitles (.stl)
  • Plaintext Transcript (.txt)

At present, ALTA RTMP does not have any output capture functionality.

The latency that’s added and passing through ALTA RTMP to your video stream is about one second. It really depends on the keyframe you set in the video itself. A typical setting is to have a keyframe rate of about one second, which will make your pass-through delay on ALTA RTMP about one second.

No, LEXI Text is its own subscription fee.
