Compress Standard: MPEG-4

MPEG-4 is the video and audio compress standard for mainly website stream, disc, visual phones, and broadcasting. MPEG-4 files typically have an .MP4 file extension.

What is MPEG-4?

Just like MPEG-1, 2, 3, MPEG-4 is also a compressive method of audio and visual (AV) digital data. It was introduced in 1998 and served as a standard for a group of video and audio coding formats. MPEG-4 is used widely in compression of AV data for web (as streaming media) and CD distribution, voice (for telephone and videophone), and broadcast television applications.

MPEG-4 also features open in source, and so companies and institutes develop different formats due to MPEG-4 standard. The popular video formats like WMV9, QuickTime, DivX, Xvid, etc. are all under the standard of MPEG-4.

What Are the Functions of MPEG-4?

  • · Improved coding efficiency over MPEG-2
  • · Ability to encode mixed media data (video, audio, speech)
  • · Error resilience to enable robust transmission
  • · Ability to interact with the audio-visual scene generated at the receiver
