Helix DNA is a project to produce software that can play audio and video media in various formats, aid in producing such media, and serve them over a network. It is intended as a largely free and open source digital media framework that runs on numerous operating systems and processors (including mobile phones) and was started by RealNetworks which has contributed much of the code.[1][2] The Helix Community is an open collaborative effort to develop and extend the Helix DNA platform.[3]

Helix DNA Client is the multi-platform multi-format media playback engine. Helix Player is a media player that runs on Linux, Solaris, Symbian and FreeBSD and is built on top of Helix DNA Client. Helix DNA Producer is an application that can aid in the production of media files, and Helix DNA Server can stream media files over a network.



The code is released in binary and source code form under various licenses, notably the proprietary RealNetworks Community Source License and the free and open source software RealNetworks Public Source License. Additionally, the Helix DNA Client and the Helix Player are licensed under the popular GNU General Public License (GPL) free and open source license.

Use of the RDT, the default proprietary Real data transport, and of the RealVideo and RealAudio codecs requires binary components distributed under the Helix DNA Technology Binary Research Use License.

Helix DNA Client

Helix DNA Client powers many digital media applications, including RealPlayer for MS Windows, Mac OS and Linux (since version 10), RealPlayer Mobile, and Helix Player. It is used on Nokia, Motorola, Samsung and Sony Ericsson mobile phones. According to https://helixcommunity.org, 350 million mobile phones with the Helix client have been shipped since 2004. It is also being used in embedded devices like the Internet Tablet OS from Nokia, which is found on the Nokia 770, N800 and N810 Internet Tablets. Cingular Video is also based on the framework. Other projects that use the Helix framework include RealNetwork's Rhapsody online music service, the Banshee and Amarok music players, and MediaReady 4000. Helix DNA also manifests itself as the RealPlayer on Mobile Internet Devices (MID) and on Netbooks.
