 You want your live content to be streamed over the C3VOC infrastructure during CCCongress or another large event? Here's how.

 To make sure your stream works on day 1 of the event we need to know of it beforehand so we can:

-===== Icecast Matroska Ingest =====
+##### Ingest Formats
-This is our preferred format for origin streams, because it supports open codecs and multiple audio/video-channels in a single-stream.
+#### SRT Ingest
+SRT is our preferred method of ingest, because it performs well even over flaky networks.
+Please note however that SRT won't prevent you from saturating your uplink, so choose a streaming bitrate appropriate for your ISPs bandwidth.
