RealMedia

RealMedia (sometimes called RMFF) is a multimedia container format associated with the RealVideo/RealAudio/RealPlayer ecosystem.

Disambiguation
At the end user level, a RealMedia file is likely to be described as being in RealVideo (if it contains video) or RealAudio (if it contains only audio) format, instead of "RealMedia". But note that the terms RealVideo and RealAudio can also encompass other things, such as codecs, and the older RealAudio format.

RealMedia can mean just the (newer) format with signature ".RMF", or it can be expanded to also encompass the older audio-only RealAudio format with signature ".ra". This article is mainly about the newer format. For the older format, see RealAudio.

There is also a thing named RealMedia HD, which is probably just a codec, not a file format.
