Compressed video data processing with conversion of image compression format
First Claim
1. A compressed video data processing apparatus comprising:
- a first recording and reproducing device, including a storage device and connected to an 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 an 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 different from that of the first image compression format.

Abstract
A local server 102 records compressed digital video data according to a first image compression format at normal and four times speeds, while a main server 106 records compressed digital video data according to a second image compression format at normal speed. An image format converter 104 is provided between the local and main servers 102 and 106. The image format converter 104 converts compressed digital video data according to the first image compression format output at normal speed from the local server 102 to compressed digital video data according to the second image compression format to be sent to the main server 106. The image format converter 104 also converts compressed digital video data according to the second image compression format output at normal speed from the main server 106 to compressed digital video data according to the first image compression format to be sent to the local server 102. 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.
