- Description
- M4V is a video container that stores audio and video data used for iTunes files. Files of this type may be protected from illegal viewing and copying with Apple FairPlay DRM. In this case audio or video files should be bought in iTunes store. Not protected files can be viewed almost in any modern player because the format is based on MPEG-4 structure.
- 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.
