METHOD AND APPARATUS FOR PROVIDING COMPUTER-COMPATIBLE FULLY SYNCHRONIZED AUDIO/VIDEO INFORMATION

摘要

A display and input method and apparatus providing fully synchronized audio/video information for use with computers and for display on computer-compatible monitors is described. The display and input system includes a computer interface, and provides synchronized digital video and audio input, as well as synchronized digital and analog audio/video output. The display and input system provides synchronization of moving images for display on 72 Hz and 75 Hz computer-compatible monitors. The display and input system facilitates 72 Hz and 75 Hz display of synchronized moving images, such as 24 fps tripled on 72 Hz computer-monitor displays, without using frame dropping or tearing techniques. In accordance with one aspect of the present invention, a "triple-repeat" method (of 24 fps and 25 fps video) is used to provide synchronized display onto 72 Hz and 75 Hz displays, respectively. A "double-repeat" method is used to provide synchronized display of 36 fps and 37.5 fps images on 72 Hz and 75 Hz displays, respectively.
