What is MPEG-4?

Because audio and video files are so large, it was required to compress them while maintaining sufficient quality. In 1988, the Moving Pictures Experts Group (MPEG) was founded in the search for this goal. The result was a MPEG family of standards for compression of sound and videos, created under the auspices of the International Organization for Standards (ISO) and the International Telecommunication Union (ITU). Several MPEG standards such as MPEG-3 were outdated. Standards are still used: MPEG-1 and MPEG-2, used for video on CD, DVD and digital TV; MPEG-4 used for sound and visual data; MPEG-7 used for meta-data; and MPEG-21 designed for digital rights infrastructure.

In terms of internet media, MPEG-4 is considered an international standard. It is made for multimedia-sound sound and video, but also text, 3-D objects, computer graphics known as Sprites and other media types. The MPEG-4 prostate is based on Apple QuickTime file format and has been developedAfter MPEG-1 and MPEG-2. It was first approved in October 1998, adopted as an international standard in 2000, and in 2002 it was included in QuickTime.

One of the key features of the MPEG-4 standard is that it is scalable. This means that it adapts to different circumstances and works well at very different data transfer speeds. In other words, it can supply the content satisfactorily via dialing, and through high width width systems. Can supply video MPEG-2-TJ. Video about DVD-a quality using smaller files and even working with lower flow flow flows.

Although MPEG-4 is standard, there were concerns that it could be implemented in different ways, leading to frustration when moving between devices. Internet streaming of media alliance (ISMA)-group 32 companies founded by Apple, IBM, Cisco, Philips, Kasenna and Sun Microsystems-Tit interoperability in MPEG-4 implementation. ISMA sets profiles to ensure that everything works together.

There is one part of the MPEG-4 standard, which is often referred to separately. The MPEG-4 Part 10 is also called the H.264 video codec and it seems that the SAVE menu is in software, such as QuickTime.
