# Ensure correct setup on the HLS upstream server
<a name="setup-uss-hls"></a>

An operator at the upstream server must set up the source content on the upstream system. Make sure that the operator sets up as follows:
+ They set up to deliver the correct number of sources:
  + If the MediaLive channel is a standard channel, the operator must set up two sources for the content. They must make sure that the two sources are identical in terms of video resolution and bitrate.
  + If the MediaLive channel is a single-pipeline channel, the operator must set up one source for the content. 
+ They set up to make the M3U8 manifest files available at the agreed URLs. These are the URLs that you obtained in [step 1](setup-input-link-obtain-info.md), and that you configured into the HLS input. They correspond to the URLs shown in [the diagram after this procedure](setup-hls-result.md).
