RTD1395 MEDIA CHIPSET 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.
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 FULL BLU-RAY MENU SUPPORT Realtek-based Dune HD media players have the best-in-class support for playback of Blu-ray disc images in full Blu-ray menu mode, including full support for BD-J, BD4K, BD3D, HD audio, obfuscated playlists and seamless branching. Blu-ray images can be played in any format (BD ISO file and BDMV folder) and from any source - local drive (USB, SATA) or network drive (SMB, NFS).
100% SMOOTH BLU-RAY PLAYBACK Dune HD media players are the only Realtek-based players with a fully-functional robust Blu-ray playback engine, which implements 100% complete support for "seamless branching".
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).
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.

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.

PROVEN HISTORY OF SOFTWARE UPDATES 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).
