Not to be confused with Helix (database).

Helix DNA was a project to produce computer software that can play audio and video media in various formats and aid in creating such media. It was intended as a largely free and open-source digital media framework compatible with numerous operating systems and processors (including mobile phones) and it was started by RealNetworks, which contributed much of the code.[1][2] The Helix Community was an open collaborative effort to develop and extend the Helix DNA platform.[3] The Helix Project has been discontinued.[4][5]

Helix DNA Client is a software package for multi-platform, multi-format media playback. Helix Player is a media player compatible with Linux, Solaris, Symbian, and FreeBSD and uses the Helix DNA Client. The Helix DNA Producer application aids in producing media files, and Helix DNA Server can stream media files over a network.

Licenses

[edit]

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.[6]

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.

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.

Developers from the Open Source Lab announced in 2007 they would use Helix technologies for content creation applications and collaboration in the One Laptop Per Child project.[8][9]
