2.2.6.26 X-Receding-PlaylistChange

  • Article

The X-Receding-PlaylistChange header is defined only for use in an Announce (section 2.2.7.1) request sent to a client. The header indicates that the playlist entry described by the SDP in the Announce request is the previous entry in the server-side playlist.

The server MUST NOT send this header unless it was rewinding the content (that is, streaming the content backward) and sent the Announce request as a result of reaching the beginning of the playlist entry.

The syntax of the X-Receding-PlaylistChange header is as follows:

 X-Receding-PlaylistChange = "X-Receding-PlaylistChange: 1"
