What types of subtitles can be generated?

Subtitle Generation Based on Input Signal:

In Deep Live Hub, the type of subtitles generated depends on whether your input signal is audio or video. Subtitles can be provided in different formats, including SRT files, HLS text streams, or rendered directly into the video as burned-in or closed captions.

Subtitles from an Audio Stream:

If your input signal is an audio stream, subtitles can be generated in the following formats:

1. SRT File:
   • A text stream of subtitles and translations that can be consumed via the Latest SRT URL.
2. HLS Egress:
   • Subtitles and translations delivered as a HLS text stream for real-time playback.
3. HLS Realtime Egress:
   • Subtitles and translations delivered as HLS realtime text streams, with faster updates for low-latency scenarios.
4. Live Viewer:
   • Subtitles and translations can also be displayed in real-time via a browser using the Aiconix Live Viewer.

Subtitles from a Video Stream:

If your input signal is a video stream, subtitles can be generated as:

1. SRT File:

   • Subtitles and translations available via the Latest SRT URL.

2. HLS Egress (Video + Text):

   • Subtitles and translations embedded into the video stream and delivered via HLS.

3. HLS Realtime Egress (Video + Text):

   • Faster real-time subtitles and translations embedded into the video stream and delivered via HLS Realtime.

4. Live Viewer:

   • Subtitles and translations can be displayed in real-time via the Aiconix Live Viewer.

5. Burned-In Subtitles (RTMP Egress):

   • Subtitles and translations are permanently burned into the video stream, making them a part of the video, and can be consumed via RTMP.

1. Closed Captions (RTMP Egress):

   • Subtitles and translations embedded as closed captions that can be toggled on or off in the video stream, delivered via RTMP.
