  models (not only on Max 4K and Ultra 4K, as before). This new way for DSD
  audio playback is optimized and is recommended for audio output to the
  standard digital audio outputs (HDMI output and standard S/PDIF output).
  Known limitations: only stereo DSD is supported; audio file should not be
  too long (maximum supported duration is approximately 67 minutes).

• Max 4K model: Added correct support for minor hardware changes (power
  control of the built-on fan) in the recent batches of Max 4K (which are
  shipped starting with May/2019).

• Amlogic models: DSD audio playback (ISO, DSF, DFF) is now supported.
  Known limitations: only stereo DSD is supported; audio file should not be
  too long (maximum supported duration is approximately 67 minutes).

• Amlogic models: Improved support for playback of WavPack (.wv) lossless
  audio files.

• Amlogic models (latest generation only: tv174c, tv175e, tv175f, tv175p):
  Added support for launching HTML applications (which can use Dune JS STB
  API) not only via /config/stb_home mechanism (as was supported before),
  but also from PHP plugins.

• All models: Implemented subtitle synchronization correction function
  (same as was previously available on Sigma models, with an improvement
  that synchronization correction is applied to each subtitle track
  individually).

• All models: The setting "Setup / Playback / Control / UP/DOWN buttons"
  now has an additional possible choice "Show playlist menu", which can be
  convenient when watching TV channels, watching TV series, or listening
  music playlists.

• All models: "Movies" menu: Updated per-years categories, added category
  "2019+".

• All models: PowerPoint presentations in PPTX format (.pptx file
  extensions) are now also supported (in addition to previously supported
  PPT format).

• All models: "Android applications" menu now includes a preinstalled item
  for "START.RU" VOD service ( https://start.ru ), which automatically
  installs and launches AndroidTV version (optimized for TV screen) of
  START.RU Android application.

• All models: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

• All models: Small improvements and performance optimizations for TV
  plugins (improved loading of icons and EPG information).

• Some other minor improvements/fixes.

Version "190412_0053_r13" (BETA version)
Download: dune_firmware_tv175p_190412_0053_r13.dff
Changes since 190330_0254_r13:
This version adds a lot of new features such as UltraHD (BD4K) BD Menu (for
Realtek models), Netflix 5.1 audio support (for Realtek models), CUE sheets
supports, improved support for various music formats (WavPack, APE, FLAC),
various improvements in the music player, various improvements related to
the use of Hi-Fi audio output (for Max 4K and Ultra 4K models), "TV" menu
item, initial setup wizard improvements, and various other improvements.
NOTE: There were big changes in the core parts of the firwmare, so some
functions may be potentially broken in this version.

• New feature: A new graphical design for the internal audio player: now it
  shows a bigger album picture, with the information about track / album /
  artist below it (similarly to how "Now Playing" screen looks in the new
  Dune Control mobile app), and uses a new background picture.

• New feature: Screensaver is now supported in the internal audio player
  (same as was previously implemented on Sigma platforms).

• New feature: Added support for CUE sheets (same as was previously
  available on Sigma-based models) in internal player.

• New feature: Added a decoder for WavPack audio files (same as was
  previously available on Sigma-based models) in internal player.

• New feature: Realtek models: Added a support for playback of audio files
  in APE (Monkey's Audio) format (same as was previously available on
  Sigma-based models) for internal player. (On Amlogic models, APE playback
  was already supported.

• New feature: Realtek models: Added a new decoder for FLAC audio files
  (same as was previously available on Sigma-based models) in internal
  player, for improved compatibility with various FLAC file format
  variations. This in particular fixes problems with impossibility to time
  seek in some FLAC files. (On Amlogic models, there were no such
  problems.)

• New feature: Added a new main screen item "TV" which can be used as a
  convenient shortcut for quick start of the preferred TV application. The
  TV application can be any Dune HD application or any Android application.
  Added a feature for automatic searching of suitable community TV
  applications in Internet (similarly to how comminity Movies extensions
  are searched). The new setup section "Setup / Applications / TV" can be
  used to modify reconfigure "TV" item and to hide it.

• New feature: The initial setup wizard now has "auto" and "manual" modes,
  "auto" mode tries to avoid asking any questions and configure everything
  automatically. No questions are asked in case of Ethernet connection, and
  only Wi-Fi network is asked to be configured in case of Wi-Fi connection.

• New feature: The initial setup wizard now allows to skip network
  configuration by choosing "None" option.

• Improvement: Added a special optimization which disables Android feature
  to automatically scan of all the connected user storage devices for media
  files (which can be used by some Android applications). This Android
  feature was almost never useful, but was causing unneeded background
  activities and system load (especially when a huge HDD with a lot of
  files is attached), which could nevatively affect the performance of the main
  functionality of the player.

• Improvement: Added a special optimization which disables Android feature
  to automatically create Android system folders and files (used by some
  Android applications) on the connected user storage devices. This Android
  feature was almost never useful, but was causing unneeded writes to user
  storage devices and appearance of undesired files on the storage devices.
  Now such folders and files are created only on a dedicated partition of
  the internal flash memory.

• Realtek models: New version of BD Menu playback engine:

    • New feature: BD Menu playback mode now supports Ultra HD BD images
      (BD4K).

    • New feature: When using the new Dune Control mobile app, in BD Menu
      playback mode, the name of the currently played file is shown in the
      mobile app.

    • New feature: When using the new Dune Control mobile app, in BD Menu
      playback mode, it is now possible to time seek (change playback
      position) in the mobile app; also the current playback position in
      the mobile app is now displayed more correctly.

    • Improvement: Improved support for remote controls with a reduced set
      of buttons:
        • Playback menu can now be shown by first pressing INFO RC button
          to show INFO OSD and then pressing POP UP MENU RC button.
        • Playback can now be stopped by choosing "Exit player" action in
          the playback menu.

    • Improvement: Optimized the performance of handling of BD Menu for
      some BD images, some BD images and some BD scenes in some BD images
      now start faster.

    • Bugfix: Some BD images did not work correctly in some cases.

    • Bugfix: When starting BD Menu playback simultaneously with the
      internal player working in background mode, a hint about TOP MENU RC
      button could be wrongly displayed on the screen.

• New feature: Realtek models: When using Netflix application,
  multichannel (5.1) audio playback is now supported.

• New feature: Amlogic models: when playing IPTV stream via HTTP/TS or HLS
  media streaming protocol, the user can now record the currently played
  stream to the local storage by pressing "REC" RC button (same as it was
  previously implemented on Sigma based models).

• New feature: Amlogic models: the use can now see the current bitrate of
  the currently played media stream in the INFO OSD menu (same as it was
  previously implemented on Sigma based models).

• Improvement: Amlogic models: Improved playback of HLS streams in some
  cases.

• Improvement: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

• Improvements for PHP plugins and PHP API:

   • Added "style=smart_label" feature for button GUI controls.

• Updated/improved UI translations for some languages.

• Some other minor improvements/fixes.

Version "190330_0254_r13"
Download: dune_firmware_tv175p_190330_0254_r13.dff
Changes since 181123_2042_r13:
NOTE: The main feature of this firmware update is the support for the new
mobile app ("Dune Control"). It does not include the support for BD4K menu
and the support for CUE in the internal player -- these features will be
included into next versions.

• New feature: Added support the new mobile app ("Dune Control"):
    • Main new features of the new mobile app:
        • Navigator (new):
            • Browse and choose media content via Dune UI shown directly on
              your mobile device.
            • Access local and network sources, Favorites, Recent, My
              Collection, Movies, Dune HD PHP plugins, etc.
            • The menu shown on the mobile device mirrors the menu shown on
              the TV screen.
            • Enter text into text fields in Dune UI using native keyboard
              on your mobile device.
            • Photo viewer mode: view photos from the Dune HD device on the
              mobile device, control photo slide show.
        • Now Playing (new):
            • See the information about the currently played media content,
              including (when available) movie poster, movie title, music
              cover, music album/artist/track information.
            • Control the playback (play/pause, stop, previous/next,
              playback position, volume).
        • Remote (similar as in the old mobile app):
            • Fully replaces the standard IR remote control.
            • Uses Wi-Fi to connect to the local network.
            • Automatically searches for Dune HD devices in the local
              network.
            • Allows to control multiple Dune HD devices and easily switch
              between them.
    • More information and mobile app download:
        • http://dune-hd.com/dunecontrol/

• New feature: Added support for music tags and covers (same as it was
  implemented previously on Sigma-based models.

• New feature: Added support for chapters in MKV files (same as it was
  implemented previously on Sigma-based models.

• New feature: Added simple parental control mechanism for file browser.
  Put "pin_code = NNNN" line into "dune_folder.txt" file in any folder to
  protect this folder by the specified pin code.

• New feature: It is now possible to add the following items to Favorites
  menu: network folders, storages, "Internal Memory" folder.

• New feature: Recent menu now shows movie posters for files which are
  recognized as movies (works when the file was recognized as a movie when
  the file was added to Recent menu).

• New feature: When viewing Movie description in the Movie screen, it is
  now possible to move focus into the description area by pressing RIGHT
  button, and then scroll through the description via UP/DOWN buttons.
  (Helpful when using remote controls w/o P+/P- buttons.)

• New feature: Realtek models: Added automatic detection of the encoding of
  external subtitles, similarly to how it was implemented previously on
  Sigma-based models.

• New feature: Realtek models: The setting "Setup / Audio / Digital audio
  output mode" now have 3 possible choices: "Auto", "PCM (decode)",
  "Original (bitstream)" (default is "Auto").
    • "Auto": use PCM or Bitstream on HDMI output based the capabilities of
      the connected HDMI equipment (automatically detected via HDMI EDID);
      use Bitstream on S/PDIF output.
        • This choice should be suitable in most cases.
    • "PCM (decode)": use PCM on both HDMI and S/PDIF outputs.
        • This choice is useful to force PCM on HDMI output when the
          connected HDMI equipment works incorrectly and provides wrong
          EDID information, or when the connected S/PDIF receiver does not
          support bitstream audio formats (Dolby/DTS), or when it is
          desired to decode bitstream audio formats (Dolby/DTS) on the
          media player side for any other reason.
    • "Original (bitstream)": use Bitstream on both HDMI and S/PDIF
      outputs.
        • This choice is useful to force Bitstream on HDMI output when the
          connected HDMI equipment works incorrectly and provides wrong
          EDID information.

• New feature: Realtek models: Added new setting "Setup / Audio / Maximum
  digital outputs sample rate" with possible choices "Auto" and "192 KHz"
  (default is "Auto" when "Digital audio connector" setting is set to
  "HDMI", "192 KHz" when "Digital audio connector" setting is set to
  "S/PDIF").
    • "Auto": the system automatically detects the maximum allowed sample
      rate based on HDMI EDID information.
        • This choice usually should be used when audio is output via HDMI.
    • "192 KHz": the system allows output of up to 192 KHz sample rate via
      S/PDIF even if HDMI EDID information does not allow 192 KHz.
        • This choice is useful when outputting video directly to a HDMI TV
          (which does not support 192 KHz) and simultaneously outputting
          audio via S/PDIF to an A/V receiver, given that the used A/V
          receiver and the used S/PDIF cable support 192 KHz.

• Improvement: Movie posters are now always displayed with the
  correct/original aspect ratio (previously movie posters could be slightly
  stretched); GUI layout of the screens with movie posters is slightly
  modified correspondingly.

• Improvement: The special support for launching playback via an external
  SPMC/KODI application can now be used not only with SPMC version 16.x (as
  before), but also with SPMC version 17.x and with KODI of any version. If
  any of these alternative SPMC/KODI versions is installed by the user (and
  no other SPMC/KODI versions are installed), the installed version will be
  used (instead of automatically installing SPMC 16.x, as took place
  before). NOTE: The default SPMC 16.x should not be installed or should be
  deleted (if it was installed) in order to use this feature.

• Improvement: Improved support for USB keyboards.

• Improvement: My Collection: when choosing a folder to add to My
  Collection, "Add to collection" action is now always available via POP UP
  MENU. (Helpful when using remote controls w/o SELECT button.)

• Improvement: RC button presses are now better handled during initial
  setup wizard in some cases.

• Improvement: Kartina.TV application updated to include some new features,
  improvements and fixes which were previously implemented in Kartina.TV
  STBs.

• Improvement: Ultra 4K: In Audio Setup, in ESS DAC source setting,
  "Internal source" renamed to "Media player" for better clarity.

• Bugfix: Ultra 4K and Max 4K: When Hi-Fi audio output (XMOS) is used,
  Hi-Fi audio output may become not working in some cases when using
  HiByMusic external app and after that using another player.

• Bugfix: Ultra 4K and Max 4K: When Hi-Fi audio output (XMOS) was enabled,
  and "Digital audio output mode" setting was set to "Bitstream", Hi-Fi
  audio output did not work for bitstream audio formats (Dolby/DTS). Now,
  when Hi-Fi audio output (XMOS) is enabled, the media player automatically
  decodes bitstream audio formats (Dolby/DTS) not depending on "Digital
  audio output mode" setting.

• Bugfix: Realtek models: Stability improvements. Fixed the problem which
  could cause frequent "Application stopped" errors and other system
  instabilities in some cases.

• Bugfix: Realtek models: When Bitstream audio output was enabled, output
  of AAC audio could not work in some cases.

• Bugfix: Realtek models: It was impossible to configure some 4K video
  modes when using specific 4K HDMI equipment which does not fully support
  all HDMI 2.0a features (such as Epson 8300/9300 projectors).

• Bugfix: Realtek models: Switching subtitles could not work in some cases.

• Bugfix: Realtek models: Some HTTP/TS streams could not be played
  correctly (playback restarts and hangups could happen) in some cases.

• Bugfix: Realtek models: When CEC was enabled, TV wakeup could not work
  properly on exiting software standby mode in some cases.

• Bugfix: Amlogic models: Fixed problem with unneeded CPU usage when CEC
  was disabled.

• Bugfix: Amlogic models: Fixed problem that an external storage could not
  be mounted in some cases (because of a problem when attempting to check
  it for filesystem errors)

• Bugfix: Amlogic models: Fixed problem with DHCP client working
  incorrectly in some cases (network connectivity could be lost after a
  while in some cases).

• Bugfix: Amlogic models: Fixed problems with playback of network streams
  in some cases.

• Bugfix: Amlogic models: Some HEVC video files could not be played.

• Bugfix: Amlogic models: When video mode was set to Auto (EDID), this
  could work incorrectly when auto framerate was used in some cases.

• Bugfix: Amlogic models: Extra unneeded HDMI reinitialization could take
  place during boot.

• Bugfix: Traveler: Battery status could be indicated wrongly after
  power-on in some cases.

• Bugfix: When playback was started by IP Control command and screensaver
  was active, screensaver was not cancelled.

• Bugfix: Errors during playback of catchup TV streams could be handled
  wrongly in some cases (restoring Live TV playback instead of restoring
  catchup TV playback).

• Bugfix: Some HLS streams could not be played.

• Bugfix: Fixed problem that navigation buttons (left/right/up/down) did
  not work via IP Control in mouse emulation mode.

• Bugfix: Fixed problem that long-press of POWER RC button was wrongly
  detected faster than in 2 seconds in some cases.

• Bugfix: POP UP MENU could work wrongly in text edit fields in some cases.

• Bugfix: "Play with..." function could work incorrectly in some cases and
  could crash in some cases.

• Bugfix: When Composite video output was used, Setup menu could crash in
  some cases.

• Bugfix: Office files (such as .xlsx) were wrongly not recognized as
  office files in some cases.

• Bugfix: Icons shown in Favorites menu could become incorrect in some
  cases.

• Bugfix: "dune_firmware.dff" file was wrongly highlighted as audio (SACD
  DFF) file.

• Bugfix: GUI hint about D button could be shown incorrectly in some cases.

• Improvements for PHP plugins and PHP API:

    • New feature: Added support for color button actions without captions
      in control folders and regular folders.

    • Bugfix: Parameters for handle_user_input in control dialogs could be
      handled wrongly in some cases.

    • Bugfix: P+/P- buttons could not work correctly in cntrol dialogs in
      some cases.

    • Bugfix: Restoring GUI state in could work wrongly in some cases.

    • Bugfix: When the playback of the current playlist list item (e.g. TV
      series episode) finished in plugin playback mode, and the main menu
      was shown, the system wrongly did not automatically start the
      playback of the next playlist item.

• Improvements in IP Control protocol:

    • IP Control protocol extended with a lot of new features to support
      the new mobile app. In particular, added support for getting detailed
      information about the current UI state, and for controlling the UI
      state, to allow external applications to implement external browsers
      for Dune UI. For more information, see the description of protocol
      version 5 here:
        • http://dune-hd.com/support/ip_control/dune_ip_control_overview.txt

• Updated/improved UI translations for some languages.
