| Description | RM (RealMedia) is a proprietary multimedia container format developed by RealNetworks. It was primarily used for streaming audio, video, and other multimedia content over the internet. RM files typically contain audio and video codecs that are optimized for streaming over low bandwidth connections. |
| Technical details | The RM format is based on a modified version of the standard MPEG-4 compression algorithm and is capable of providing good video and audio quality while keeping file sizes small. The format also includes support for digital rights management (DRM) to protect copyrighted content from unauthorized access and distribution. RM files can be played using RealPlayer, a media player application developed by RealNetworks, which is available for various platforms such as Windows, macOS, and Linux. Additionally, some third-party media players may also be capable of playing RM files by using appropriate codecs. |
