Abstract
A local server records compressed digital video data according to a first image compression format at normal and four times speeds, while a main server records compressed digital video data according to a second image compression format at normal speed. An image format converter converts compressed digital video data according to the first image compression format output at normal speed from the local server to compressed digital video data according to the second image compression format to be sent to the main server. The image format converter also converts compressed digital video data according to the second image compression format output at normal speed from the main server to compressed digital video data according to the first image compression format to be sent to the local server.
