Key Features

Key advantages over competitors


RTD1395 media processor

  • Dune HD RealBox 4K is the world's first retail media player on the new RTD1395 media processor – a next-generation media processor from Realtek.


  • The media player supports not only HDR technology (supported by the previous generation of media players), but also the most latest and advanced HDR10+ technology from Samsung. In conventional HDR technology, the brightness range is set at the beginning of the film and does not change during the film, so completely dark and completely bright scenes may have insufficient detail. In the latest HDR10 + technology, the brightness range can vary from frame to frame, so the maximum picture detail is provided even in scenes that contain only dark or only light elements.

VP9 profile 2 and YouTube 4K HDR support

  • The media player supports not only the old VP9 video codec (which does not support HDR), but also the newest VP9 profile 2, which supports HDR and which is used in YouTube for 4K HDR content. Most other media players do not support it.

Best-in-class movie ISO/folder structure playback

  • Realtek-based Dune HD media players have the best-in-class support for playback of movie ISO/folder structures, including full support for 4K, 3D, HD audio. Movie ISO/folder structures can be played from any source - local drive (USB, SATA) or network drive (SMB, NFS). A special engine helps to ensure smooth playback of the entire movie w/o any audio/video interruptions even when playing movies with complicated structure.

    Flicker-free framerate/resolution switching

    • Dune HD media players implement its own advanced flicker-free approach for automatic framerate and resolution switching, which performs video mode switching before the start of file playback (rather than after). Most other Realtek-based media players perform video mode switching after the start of file playback, which causes unpleasant flickering.

    Professional-grade controls for video output parameters

    • Advanced setup controls allow professional users and installers to fine tune the video output parameters in the best way for a particular setup. In particular, it is possible to configure what chroma subsampling modes should be used for each individual HDMI video mode. The majority of competing media player models do not have such controls.

    Widevine L1 and premium video services

      • Support for Widevine Level 1 DRM (the most advanced DRM level) makes it possible to watch premium online video services with HD and Ultra HD video quality. Media players w/o Widevine Level 1 support can only output Standard Definition video in such services. 

    NOTE: Netflix is not currently supported.

    Linux-based Dune HD OS

    • The media player runs a unique hybrid OS which consists of a Linux-based Dune HD OS (to ensure stable operation and smooth media playback) and Android OS (to support Android applications), which run simultaneously.

    Dune HD Android Playback Accelerator technology

    • This unique technology intellectually manages the resources of Android OS to minimize the influence of Android OS on the media playback engine and ensure smooth and high-quality video and audio playback.

    Dune HD ecosystem

    • Based on open Dune HD SDK and APIs, various TV-optimized applications, plugins, extensions, GUI skins, collection management solutions, integrations with home automation systems are available via official Dune Store, 3-party vendors, and from the huge user's community.

    Dune HD UI

    • The famous Dune HD UI, developed and polished during more than 12 years, specially optimized for the use on TV screens and operation via a standard remote control, tuned for the best possible usability, makes it easy and convenient to use the media player.

    Dune HD movies organizer and movies encyclopedia

    • “My Collection” function organizes a user's movies collection into a nice looking catalog. A comprehensive movies encyclopedia provides the information about hundreds of thousands of movies with detailed descriptions, posters, cross-links between movies and persons, trailers, direct links to online video services, etc. Advanced file browser automatically recognizes movies.

    Dune HD mobile app

    • The unique Dune HD mobile app (Dune Control) for iOS and Android mobiles devices provides full access to all functions of Dune HD media player in a very convenient and powerful way. It fully replaces the standard IR remote control, allows browsing and choosing the media content directly on your mobile device (the menu shown on the mobile device mirrors the menu shown on the TV screen), and includes Now Playing section for convenient media playback control.

    Smart home

    • The media player provides the powerful IP Control interface and has a lot of options for integration into Smart Home and Home Automation systems, such as Control4 and Crestron.

    Proven history of software updates during a very long period

    • Dune HD is known for its reputation to listen to user's feedback and provide software updates for many years. For example, for some old models, software updates with additional functions are provided for more than 10 years already. This is possible due to the unique "single code base" approach, which means that firmware for all Dune HD models is based on the same software (continuously developed and improved according to user's feedback).

    World’s most compact Realtek-based media player

    • Dune HD RealBox 4K is the world’s most compact media player based on a modern Realtek media processor. It has a very compact metal casing (just 109x109x21mm).
