Next discards the item that is currently playing on the server output.

In single shot mode, the server loads the next item in the playlist, and is ready to play from the cue point of that item.
In block play mode, the server continues to play without interruption, sequencing smoothly into the following item before reaching the end of the current item.

This function is useful when an item is exceeding its allotted time, for example when the item must match the length of a live voice over.
