Compressed video data processing with conversion of image compression format
First Claim
1. A compressed video data processing apparatus for use with an external digital video cassette recorder and an external recording and reproducing device, said apparatus comprising:
- a first recording and reproducing device, including a storage device and connected to the external digital video cassette recorder, for recording and reproducing compressed digital video data according to a first image compression format; and
an image format converter, connected between said first recording and reproducing device and the external recording and reproducing device, for converting compressed digital video data between the first image compression format of said first recording and reproducing device and a second image compression format of the external recording and reproducing device, wherein the second image compression format is different than the first image compression format,wherein said first recording and reproducing device is operable convert transfer speeds such that the compressed digital video data is transferred between the external digital video cassette recorder and said first recording and reproducing device at a first transfer speed and the compressed digital video data is transferred between said first recording and reproducing device and the external recording and reproducing device at a second transfer speed different than the first transfer speed.

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.
