M4V vs MP3:
|Full name||Raw MPEG-4||MPEG-1 or MPEG-2 Audio Layer III|
|MIME||video/x-m4v||audio/mpeg, audio/MPA, audio/mpa-robust|
|Developed by||Apple Inc.||Fraunhofer Institute|
|Type of format||Video container||Digital audio|
|Introduction||The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files in its iTunes Store.||MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.|
|Technical details||Unauthorized reproduction of M4V files may be prevented using Apple's FairPlay copy protection. A FairPlay-protected M4V file can only be played on a computer authorized (using iTunes) with the account that was used to purchase the video.||The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source.|
