- Description
- RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
- The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.
