NONLINEAR VIDEO EDIT DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To allow a personal computer to display DV stream data in a wide mode from a DV video camera in an aspect ratio of 16:9 by using a conventional video moving picture driver and a conventional edit program. SOLUTION: In this nonlinear video edit device, a video capture program 26s sets the screen size information of an AVI file to a size of 852*480 dots when a wide screen flag is set for capturing video data. A CODEC driver 26c expands data laterally to have the size of 852*480 dots when the screen size information is set to that size in the case of decompression. A video moving picture driver reserves memory areas for the size at the time of editing by setting the screen size information of the AVI file to the size of 852*480 dots in the case of capturing. A personal computer can display DV stream data in the wide mode without the need for separate storage of the screen flag information to a header of the AVI file.
