Lisa Compact 22

Playing a stream or playlist from internet
By default the Lisa will connect to the Streamit Device portal. If the Lisa is registered on the Streamit
Device portal, the device will get a list of presets. When powered on the first time, the Lisa will start to
play the stream or playlist of the first preset.
A preset can be the URL of an audio file, a stream or a playlist. Specifically the following online audio
sources are supported:
o An audio file on a web server
o An HTTP internet audio stream (Icecast, Shoutcast)
o A playlist in the PLS format (see Wikipedia PLS format description)
o A playlist in the M3U or M3U extended format (see Wikipedia M3U format description)
o A playlist in the ASX format (see Microsoft documentation)
See Using a playlist as preset for more information on presets that point to playlists.
6.1 Change which stream is played
There are several options to change the preset (stream or playlist) that is played by the Lisa:
·
Using a task (see Task scheduling)
·
Using a command, for example via Lisa Configuration Tool or the monitoring server (see Remote
control from monitoring server). See Controlling the Lisa with commands for a complete overview.
6.2 Using a playlist as preset
The URL of a preset can point to a playlist that is available online on a web server (an 'online playlist').
The Lisa will not store this playlist on the SD card for later use (see Store-and-Forward for this), but will
simply play the playlist immediately after retrieving it.
The URLs in a playlist can point to an internet stream, which useful to configure a backup stream in
case the first (primary) stream is not available: When a stream stops (e.g., when the connection fails),
the Lisa will try to connect to the next entry in the list
An online playlist can also be used to dynamically change during the day what the Lisa plays. In this
case the URL in the playlist points to a file rather than an audio stream. The variants of this application
are explained in their respective sections: Single track playlist and Mixed source playlist.

Requirements for online playlists
