ABSTRACT:
Video image quality is preserved in an asynchronous network by providing a synchronizing arrangement in which the input of video data from an asynchronous network to a video data buffer is synchronized with the reading of information from the video data buffer. Synchronizing video data transfers to and from a video data buffer ensures that video data from only a single frame from a source is displayed on a display monitor at one time, thus maintaining image quality. Furthermore, multiple video data streams from several asynchronous sources can be displayed simultaneously on a single display screen using the synchronization technique. The synchronization arrangement synchronizes receipt of the different data streams into the frame buffer with the output of data from the frame buffer to the display screen.
