Today, MPEG-2 is the most widely used video container format. You probably see the term all the time without giving it much thought. But do you know what “MPEG” stands for or how the format came to be? In this post, we’ll briefly explore the answers to these questions and more.
What does MPEG-2 mean?
The first part of the acronym stands for the “Moving Pictures Expert Group,” which is the name of the organization that developed the file format as an international standard. The number two represents that this was the second standard that was developed (MPEG-1 was the first). It is also referred to as H.222 or H.262 by the International Telecommunication Union.
How long has MPEG-2 been in use?
This file format first became available in 1995. It replaced the MPEG-1 standard that was developed in 1993 and added support for interlacing and high definition. It was also preferred over MPEG-1 because of its lossy video and audio compression, allowing for relatively small files that maintain a high level of quality.
Where is MPEG-2 used?
MPEG-2 is not just the standard format for cable and satellite broadcasting; it is also used for movies and other programs that are stored on DVDs. To convert a file to this format so that it can be broadcast, you’ll need a MPEG-2 encoder.
Are there newer formats available?
Yes. MPEG-4, specifically MPEG-4 Part 10 or H.264 is a newer and even more efficient format that is the standard for Blu-ray Discs. Many Internet streaming sites also use this format, as well as some HDTV broadcasting stations.
Where can I get a MPEG-2 encoder?
