The relation to the RealMedia is that both in Japan and the RealMedia container formats can use the same RealVideo G2 formats, making them mostly interchangeable in a Japan-only environment. .rm and .rmvb are being an international standard with more support, especially on hardware devices and on the software side. However, this is not the case for any other video file formats in Japan.
