Title

Multimedia and CD-ROM : an overview of JPEG, MPEG and the future

Abstract

One of the keays to succesful multimedia CD-ROM database development lies in data compression. Digital images are bulky to store and slow to transmit (a single digitised colour photograph may contain 25 MB of data). Describes the 2 key standards for image compression: JPEG (Joint Photographic Experts Group) and MPEG (Moving Pictures Experts Group). JPEG is the method of choice for applications concerned solely with still images: desktop publishing; electronic photographic processing; digital scanners and colour laser printers. MPEG is more expensive and complicated but more powerful and better suited to asmmetrical applications such as CD-ROM databases
