RTD1619DR media processor

The newest RTD1619DR media processor is the most advanced and the most powerful media processor from Realtek with Dolby Vision support.

Two HDMI output ports

The additional HDMI output port allows getting the best picture and audio quality in various scenarios, for example, when using a 4K/HDR TV and an A/V receiver without 4K/HDR support.

Dolby Vision and HDR10+

The media player supports not only HDR technology (supported by the previous generation of media players), but also the most latest and advanced Dolby Vision and HDR10+ technologies. 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 Dolby Vision and HDR10+ technologies, 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.

Dolby Vision VS10 video processor

The advanced Dolby Vision VS10 video processing engine ensures maximum image quality when playing any type of content (SDR, HDR, Dolby Vision) with any type of video output signal (SDR, HDR, Dolby Vision), improves the SDR/HDR/Dolby Vision conversion quality, minimizes the effect of “posterization” (“banding”) due to more advanced 12-bit video processing. This gives benefits even when using the media player with older TVs that do not support Dolby Vision.

Playback of Dolby Vision ISO/folder structures

The media player supports direct playback of movie ISO/folder structures in Dolby Vision format (MEL and FEL). The extended Dolby Vision information is used and transmitted to the TV to improve the picture quality. This is possible due to the unique video playback and output engine created by Dune HD. Other RTD1619DR-based media players do not support this. Dune HD media players are the only hybrid network media players in the world that combine this functionality with support for Internet video services and Android applications in one device.

Widest support for Dolby Vision file formats

Dolby Vision is supported for all popular file formats (MKV, MP4, TS, M2TS, ISO, movie folder structure). All popular Dolby Vision profiles (P4, P5, P7 MEL and FEL, P8) are supported. The media player supports the largest number of variations of Dolby Vision file formats of any other media player.

Dune HD Dolby Vision Purifier

This technology, unique to Dune HD media players, optimizes Dolby Vision files on the fly for maximum compatibility with the Realtek RTD1619DR media processor. This helps to ensure the most stable playback, including incorrectly encoded files (which often cause freezes, stuttering, sound out of sync on other media players).

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.

+77% faster CPU

The media player has a 6-core ARM A55 CPU – which is +77% faster than 4-core ARM A53 used in the previous generation media players.

+50% faster GPU

The media player has the new GPU Mali-G51 – which is +50% faster than Mali T-820 used in the previous generation media players.


This is 2x more than in the previous generation media players, and gives better performance for the most heavy apps.

32 GB flash

This is 2x more than in the previous generation media players, and gives more space for the most heavy apps and internal storage.

Android 9

For Android applications, the media player uses a modern Android version 9.0. This provides improved support for the newest Android apps.

3 antennas

3 external antennas (two antennas for Wi-Fi 2T2R + one separate antenna for Bluetooth) improve the performance of Wi-Fi and Bluetooth.

Bluetooth 5.0

The media player uses the new Bluetooth version 5.0 (the previous generation media players were using version 4.x).

Other key advantages over competitors

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.

Auto framerate/resolution switching for Android applications

Dune HD media players are the only media players based on Realtek media processor which implement automatic framerate and resolution switching not only for file playback, but also for Android applications. With proper support for all framerates, including 23.976 and 24.0.

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.

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).
