What is MPEG-2 video?
MPEG stands for “Motion Picture Experts Group”, which is named after the standards committee that established the compression algorithm. MPEG-2 is the standard compression technology used for DVD video. Video must be highly compressed so longer programs can fit on a single disc. The longer the program, the greater the amount of compression required to fit the material on a disc. Higher compression rates result in poorer video quality. At Imperial Media we always use the optimal compression rate to provide the highest quality end product.
MPEG-2 Video is a generic method for compressed representation of video sequences using a common coding syntax defined in the document ISO/ IEC 13818 Part 2 (CD: Nov. 1993, DIS: March 1994) by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), in collaboration with the International Telecommunications Union (ITU) as Recommendation H.262. The MPEG-2 Video Standard specifies the coded bit stream for high-quality digital video. As a compatible extension, MPEG-2 Video builds on the completed MPEG-1 Video Standard (ISO/IEC IS 11172-2), by supporting interlaced video formats and a number of other advanced features, including features to support HDTV. As a generic International Standard, MPEG-2 Video is being defined in terms of extensible profiles,each of which will support the features needed by an important class of applications.

MPEG is developing the MPEG-2 Video Standard, which specifies the coded bit stream for high-quality digital video. As a compatible extension, MPEG-2 Video builds on the completed MPEG-1 Video Standard (ISO/IEC IS 11172-2), by supporting interlaced video formats and a number of other advanced features, including features to support HDTV. As a generic International Standard, MPEG-2 Video is being defined in terms of extensible profiles, each of which will support the features needed by an important class of applications. At the March MPEG meeting in Sydney, the MPEG-2 Main Profile was defined to support digital video transmission in the range of about 2 to 15 Mbits/sec over cable, satellite, and other broadcast channels, as well as for Digital Storage Media (DSM) and other communications applications. Building on this success at the New York meeting, MPEG experts from participating countries in Asia, Australia, Europe, and North America further defined parameters of the Main Profile and
