Video-based computer-assisted learning.

As a relevant exemplar of MPEG-1 and MPEG-2 digital video use, a multimedia computer-assisted learning (CAL) application dealing with Critical Communication Issues in medicine was developed. The application allowed the student to navigate through a series of high-quality digital video and audio clips that were delivered in near real-time from an Intranet server. This paper gives a brief background to the MPEG-2 video compression system and discusses the use of digital video in a CAL environment.
