Sometimes it can be confusing how files, items, playlists, screen layouts and time slots are processed in Slideshow. It is a powerful concept, which allows you to fully customize the content displayed on the screen. This article aims to explain this concept.

You can find all this setup in Slideshow’s web interface.

Item

Item describes what exact content should played or shown. There several types of items:

  • Single file – play exactly one file stored in the device’s internal memory
  • Files alphabetically – play one or more files stored in the device’s internal memory in alphabetical order. You can group files based on the folder they are in, prefix of their name or their extension.
  • Files randomly – play one or more files stored in the device’s internal memory in random order (special algorithm is used, so you won’t get the same file on two consecutive times). You can group files based on the folder they are in, prefix of their name or their extension.
  • Audio/video stream – network stream containing audio or video (e.g. webcam feed, internet radio, internet TV)
  • Panel with date/time – displays current date and/or time
  • Panel with weather – displays weather forecast from online service
  • Panel with RSS messages – displays RSS feeds (e.g. news)
  • Plain text – displays single line of static text, without any formatting
  • Nothing – just panel background is displayed (solid color or linear / radial gradient)
  • Today’s name day – display name that currently celebrates name day

Playlist

Playlist consists of one or more items, which are played in the set order in a cycle, until the playlist is changed (either manually or due to the time slots). During the cycle, each item is resolved to only a single file, panel or stream. This is then played for set amount of seconds (except for audio files, video files and moving RSS messages, which are always played in theirs full length). After finishing, playlist moves to the next item. There are 3 types of playlists based on how the audio is played:

  • Mute – no audio is played from the videos and streams in this playlist
  • From video – audio is played if video or video stream is displayed
  • Audio playlist – special playlist for only audio files/streams, playlist with this type cannot be assigned to the panel, see Audio playlists assignment

Panel

Panel is a rectangular area on the screen. It has defined position on the screen (in percentage of width and height), has background color which can be semi-transparent (or linear / radial color gradient consisting of two colors) and optional borders. You can also setup optional definition of animation between two consecutive images and rounded corners for the panel.

Each panel has playlist assigned through time slots, that means that the panel can display different playlists on different parts of the day or different days of week.

Screen layout

Screen layout describes what does the screen looks like. It consists of one or several panels, which can also overlap. You can use transparent or semi-transparent background color for overlapping panels.

You can assign different screen layouts to different time slots, that means you can display different screen layout on different parts of the day or different days of week.

Some diagrams for better clarification

Bellow are diagrams for two sample configurations:

Visualization of the default configuration - this is how items, playlists, panels and screen layouts are setup when you install Slideshow
Visualization of little bit more complex setup: two panels on the screen, one panel has different playlist during day and night, the day playlists consist of two items
