File Playback

The player supports playback of media files (video, music, photos) in various formats. You can play files from any drives attached to the player, or from network drives.

  • To play a media file, select the file in the file browser, and press ENTER.

  • To play all media files in the current folder starting with a certain file, select the file in the file browser, and press PLAY. The player will generate a playlist consisting of all media files in the current folder (not including files in subfolders), and will start playback of this playlist starting with the selected file.

  • To play all media files in a certain folder (including files in subfolders), select the folder, and press PLAY. The player will generate a playlist consisting of all media files in the folder (including files in all subfolders), and will start playback of this playlist.

  • To play a predefined playlist file (in M3U or PLS format), select the playlist file, and press PLAY. The player will load the playlist file, and will start playback of all items in the loaded playlist.

  • To play a given set of media files and/or folders and/or playlist files, mark all needed files and/or folders and/or playlist files using RC buttons SELECT and POP UP MENU, and press PLAY.

    • The player will generate a playlist comprising all marked content (including all marked media files, all media files in the marked folders and all their subfolders, and all items from the marked playlist files), and will start playback of this playlist.
    • During playback of a playlist, you can easily navigate through the playlist using RC buttons NEXT, PREV, POP UP MENU.

When playing video or audio files, the player uses so called "file playback mode". Entering and leaving the file playback mode may take some time, and black screen may be shown.

When playing a list of photos, a special photo viewer application is used for nice photo showing with transition effects (see "Photo Viewer" section). When starting playback of a list of media files consisting of both photos and other kinds of media files (video, audio), the player will ask whether you want to show photos or play video and audio files.

Audio CD Playback

(NOTE: This function is available only in models based on Sigma Designs media processors.)

NOTE: Models which do not have an internal optical drive require an external optical drive or extension module.

To play an Audio CD, navigate to the Main screen of the file browser, and insert the disc into the optical drive. The player will recognize the inserted Audio CD and enable the corresponding optical drive item on the Main screen. Select this optical drive item and press ENTER or PLAY. The player will start playback of the Audio CD.

When playing a Audio CD, the player treats each Audio CD track as a kind of an audio file, and performs playback of a playlist consisting of all Audio CD tracks, the same way as if the corresponding list of audio files was played in the file playback mode. The overall player behavior and available RC buttons are the same as in the file playback mode. See "File playback" section for more information.


Internet Radio Playback

The player supports playback of Internet Radio stations streamed using HTTP protocol. For information on using Internet Radio, please refer to Internet Radio .


IPTV Playback and Recording

The player supports playback and recording of IPTV channels streamed using multicast UDP protocol (raw-UDP or RTP-over-UDP). For information on using IPTV, please refer to IPTV .


HTTP Playback

The player supports playback of media content from network using HTTP protocol. This possibility is mostly intended for playback of Internet Radio (see "Internet Radio playback" section), but it can also be used for playback of other kinds of content streamed over HTTP protocol. For example, you if you have an HTTP URL pointing to some video content in a format supported by the player, you can directly play this video content on the player w/o need to download the video content in advance. Besides, when accessing UPnP servers, media content provided by UPnP servers is also played using HTTP protocol.

To manually play a specific HTTP media stream (given that you know HTTP URL of this HTTP media stream), you can prepare a playlist file (in M3U or PLS format) containing the corresponding HTTP URL, and just launch this playlist file in the player in the usual way. The player will start playback of the content streamed from this HTTP URL just like playback of any regular video/audio file in file playback mode. See "File playback" section for more information.

File formats supported for HTTP playback are basically the same as file formats supported for the regular file playback mode (however, there also may be additional specific limitations taking place only for HTTP playback).


Photo Viewer

The player supports viewing photo files as slide shows with nice transition effects. See "File Playback" section on more details on how to select photos for showing.

In the photo viewer mode, the following RC buttons are available:

  • RETURN, STOP: Stop the slide show, return to the file browser mode.

  • PAUSE: Pause the slide show.

    • To resume the slide show, press PLAY.

  • PREV (|<<), Left: Show the previous file.

  • NEXT (>>|), Right: Show the next file.

  • POP UP MENU: Toggle showing of the browser of the current playlist.

  • REPEAT: Toggle the cyclic playback of the playlist.

  • SHUFFLE: Toggle the random playback of the playlist.

  • ROTATE: Rotate the picture clockwise.

  • 1, 2, 3, 4, 5: Rotate/mirror the picture in different ways.

  • INFO: Show/hide information on the current file:

    • Format: file type.
    • Width : picture width (pixels).
    • Height : picture height (pixels).
    • Bit Depth : number of colors.

In the "Applications / Photo Viewer" section of the player settings menu it is possible to adjust the interval of picture switching (slide show) and set the type of the picture transition. If the "random" transition mode is selected, the effects will be used in a random order.

Limitations of Particular Models

Different models of Dune HD media players are based on different media processors and have differences in the supported the supported media playback functionality. Some of the listed functions may not be supported or may be partially supported on some models. Some of the most important limitations:

  • Models based on Amlogic media processors: Blu-ray Menu and DVD-Video playback is not supported by the built-on or system player and is only possible via external applications such as SPMC.

  • Models based on Realtek media processors: video zoom functionality is limited (it is not possible to zoom-in video in a way that it goes beyond the screen borders).

  • Models based on all media processors except Sigma Designs: the following functions have limitations or are absent: fast/slow playback (forward and rewind), sound synchronization adjustment, ANGLE toggle, PIP and 2nd audio toggle in Blu-ray menu, multicast playback, recording of the currently played media stream, Audio CD playback.
