DescriptionRM (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 detailsThe RM format is based on a modified version of the standard MPEG-4 compression algorithm and is able to provide high-quality video and audio 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 created by RealNetworks, which is available on various platforms such as Windows, macOS, and Linux. Some third-party media players may also be capable of playing RM files with the use of appropriate codecs.
