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.

RealMedia HD[1] is the same file format but just starts with ASCII ".RMP" instead of ASCII ".RMF".
