Compressed video data processing with conversion of image compression format |
摘要 |
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 is provided between the local and main servers. The 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. Then, compressed digital video data can be input and output at a high speed when digital video data compressed are recorded after the image conversion format is changed and compressed digital video data are output for reproduction after the image conversion format is changed.
