Using the A/V setup depicted in above, Live Capture can be used for live videos such as news broadcasting, televised interviews, and more.

Here's an organized breakdown of how to set it up:

  1. Microphone(s) Connected to Audio Mixer:
    • Multiple microphones are connected to the audio mixer, allowing for various speakers and audio sources to be managed.
    • The audio mixer is essential for controlling input levels, balancing audio, and ensuring high-quality sound for the event.
  2. Audio Mixer Output to Desktop/Laptop (Running Live Capture Web App):
    • The output from the audio mixer (via aux-out) is connected to the desktop or laptop (via aux-in).
    • The desktop/laptop is running Live Capture , a web application that supports live transcription, making it possible to generate real-time captions from multiple audio inputs.
  3. Live Capture Web App with Green Screen Enabled:
    • Live Capture is configured with Green Screen technology enabled, which allows for dynamic backgrounds or visual effects to be used during the live event.
    • This setup enhances the visual presentation by integrating the live transcription with customized video backgrounds.
  4. HDMI Output from Desktop/Laptop to Captioning Hardware (Closed Caption Encoders):
    • The HDMI output from the desktop/laptop, where Live Capture is running, is connected to the captioning hardware.
    • This connection ensures that the live transcription generated by Live Capture , along with any visual elements, is sent to the captioning hardware for further processing.
  5. Simultaneous Video Feed Input to Captioning Hardware:
    • A separate video feed, such as a camera or pre-recorded content, is inputted into the captioning hardware alongside the HDMI input from the desktop/laptop.
    • This video feed can be the main visual content of the event, which will be paired with the live captions.
  6. Live Video Output with Real-Time Closed Captions:
    • The captioning hardware processes both the video feed and the live transcription to generate a final output.
    • The final output is a live video stream with real-time closed captions embedded, ready for broadcasting or live streaming.
    • This setup ensures that the audience receives a seamless and accessible live video experience with synchronized audio, video, and captions.
