The design goal of MPEG-1 is the ability to randomly access a sequence within half a second, without a noticeable loss in quality. MPEG-2 allows the scaling of resolution and the data rate over a wide range. Furthermore, the need for data integrity and loss-free data transmission is paramount as these play an important role in mobile communications. Something completely new in MPEG-4 is the organization of the image contents into independent objects in order to be able to address or process them individually. MPEG-4 is used for video transmission over the Internet for example.
Some manufacturers plan to transmit moving images to mobile phones in the future.
MPEG-4 is intended to form a platform for this type of data transfer. MPEG-7 is the latest MPEG family project. It is a standard to describe multimedia data and can be used independently of other MPEG standards. MPEG-7 will probably reach the status of an international standard by the year 2001.
