What is the difference between .rm and .j2c?

Description: An RM file is a multimedia file used by RealPlayer, an audio and video playback and streaming program. It contains audio or video data or a link to a streaming media file, which is played back as it is downloaded. RM files are commonly used for streaming content over the Internet such as video and Internet radio.; The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
