    摘要: The present invention provides a system by which customized quality computer-based training (“CBT”) can be presented over a global network such as the Internet with low development costs, low hosting costs, inexpensive class production, and high-quality audio-visual content. A student, having an active connection to the server from a remote client, enters the CBT website and registers as a new student by providing necessary pertinent information to the server host. Upon completion of the registration process, the student begins his or her interaction with the online computer-based training plan. The online plan includes digital images and digital audio that is compressed and transmitted from a host server to the student's computer via the Internet. The images and audio are taken from digital nondigital sources and converted to a digital format. The images for a plan are selected and compressed into an appropriate compression format. The audio presented along with the video is also compressed in a similar manner. Once compressed, the images and audio are prepared for a slide show computer-based training plan format. The plan is tested for image and audio quality. Where necessary, an image or audio segment is recompressed. Better compression provides for a more fluid viewing of the plan without sacrificing image or audio quality. Additionally, server side buffer programming integrated into the plan allows optimum viewing of the streaming images and audio without concern for bandwidth limitations, thus allowing a student to complete the plans quickly and without interruptions.
