RealNetworks makes wireless streaming easier

Posted by Sachin Garg on 20th November 2005 | Permanent Link

PCWorld: RealNetworks has released an update to their Helix Server Unlimited software. With this update, users will have the capability to stream audio and video content to wireless devices. The target for the upgrade is companies who want to stream content to their employees, clients or to customers, but we know what you have in mind thinking.

The Helix Server software already supported RealAudio, RealVideo, Windows Media, MP3, MPEG-4 and Quicktime. That obviously won’t change. What the update does add is 3GPP technology, which is responsible for the streaming. The update also includes newer versions of the management protocol and firewall security.

As the name would indicate, the Helix Server Unlimited supports unlimited download streams. There are other products capped at 25 or 100 streams.

The upgrade has been released, but the pricing isn’t yet available.

The City of Seattle, where RealNetworks is based, has been using Helix Server Unlimited to stream television programs to its residents and will now add a service for handsets, RealNetworks representatives said. Virginia’s Polytechnic and State University (Virginia Tech) will also use the update to stream content wirelessly to its students, according to the company.

The company released the Helix source code so developers could prepare products that support a variety of media formats, in what RealNetworks calls an open-source delivery system.
