RealMedia

What is Real Server/Media/Audio?

RealServer is the software that streams media (RealAudio and RealVideo) over a network. The client receives the media in real-time, and does not have to wait for the clip to download.

RealMedia is any media that is specifically created to be streamed from RealServer. RealAudio is an audio only streaming format. RealVideo is a video streaming format that includes both audio and video. The RealPlayer client for viewing RealAudio and RealVideo is available for as a free download at: http://www.real.com/player .

Creating Real Audio/Video files

You can create RealAudio and RealVideo files with RealNetworks RealProducer. More information on obtaining and using RealProducer can be found at: http://www.realnetworks.com/products .

Streaming Media

Shared Streams

Shared streams are a pool of streams shared between Value, Plus, Pro and Enterprise package owners. The streams are available on a first come, first serve basis.

If your business needs require guaranteed access to streams, you should consider the dedicated streams purchasing option that comes with the Pro and Enterprise packages.

Dedicated Streams

A dedicated stream is a stream that is guaranteed to be available to the user, unlike a shared stream. Dedicated streams can be purchased by owners of Pro and Enterprise packages.

Dedicated streams allowed per user

The number of dedicated streams that a user has access to is determined by the number of streams the user has purchased. Streams are available for sale in units of five.

Supported Protocols

RTSP: Real Time Streaming Protocol is designed specially for clips created and read with RealSystem G2 tools. It is an open standard protocol that supports SureStream files as well as SMIL, RealText and RealPix files. RTSP broadcasts on port 554.

PNA: Progressive Networks Audio protocol is designed and used with RealSystem versions 5.0 and earlier. RealServer supports PNA for compatibility with older versions of RealPlayer. PNA is a proprietary protocol. PNA broadcasts on port 7070.

Uploading Files/Accessing Media

You must upload your RealMedia files to your public directory. If you upload to a subdirectory of your public directory, the subdirectory must be reflected in the access URL.

The URL used to access a RealMedia file depends on the protocol being used:

RTSP: rtsp://<your domain.com>/<your domain.com>/filename.rm

PNA: pnm://<your domain.com>/<your domain.com>/<filename>.rm
