What is MPEG ?
MPEG is the “Moving Picture Experts Group”, working under the joint direction of the International Standards Organization (ISO) and the International Electro-Technical Commission (IEC). This group works on standards for the coding of moving pictures and audio. MPEG has created its own homepage, providing information on the what, where, when and how of the standards.
Just as there are a dozen ways to do any task, there are multiple ways to compress data. To compress data means to crunch it down so that it will fit properly on a given medium, such as a DVD. When DVD technology emerged, those in the business knew that in order for this new technology to be marketable worldwide standards had to be set for DVD data storage and compression. This way, DVD disc data from one manufacturer could be read successfully on a DVD reader produced by any other manufacturer. The Movie Picture Experts Group (MPEG) has been creating standards that control the development of audio and video digital compression formats since 1988. To DVD viewers who have some insight into what makes DVDs tick, MPEG is the name of the method used to compress the audio and video into bit stream tokens. These compressions–not detectable by the normal viewer–allow data to effectively fit into smaller storage areas. That’s why an entire movie can fit onto a single DVD disc. This article sum
MPEG stands for the Motion Picture Experts Group, part of the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), charged with creating and publishing standards for various areas of technology, respectively. MPEG standards address audio and video formats used online, in television broadcasts, and in DVD media. A number of MPEG standards are in current use, and more are sure to follow. Some well-known standards are explained briefly below. MPEG-1: This first set of standards was developed for audio and video compression. MPEG-1 Layer 3 is a codec within these standards, known simply as MP3, or the popular audio compression format for music. The video format of MPEG-1 was used to store movies on CDs, known as Video CD, or VCD. Quality is equal to that of a VHS tape, and compatibility playback on CD/DVD players is high. One drawback of MPEG-1 is that it only supports progressive footage, verses the inclusion of interlaced. These terms
MPEG (Moving Pictures Experts Group) is a group of people that meet under ISO (the International Standards Organization) to generate standards for digital video (sequences of images in time) and audio compression. In particular, they define a compressed bit stream, which implicitly defines a decompressor. However, the compression algorithms are up to the individual manufacturers, and that is where proprietary advantage is obtained within the scope of a publicly available international standard. MPEG meets roughly four times a year for roughly a week each time. In between meetings, a great deal of work is done by the members, so it doesn’t all happen at the meetings. The work is organized and planned at the meetings. MPEG itself is a nickname. The official name is: ISO/IEC JTC1 SC29 WG11.
