1. An image data recording and reproducing system comprising:
- an image data input unit;
an ID generator coupled with said image data input unit,wherein said ID generator generates IDs and each ID is inserted into each of image data from said image data input unit, andwherein said ID relates to a video frame, and each ID inserted into each of said image data is different from each other;
a plurality of image data recorders coupled with said ID generator, to which said image data and said ID are applied,wherein said ID and said image data to which said ID is added are recorded in all of the plurality of image data recorders, respectively, andwherein each of said plurality of image data recorders has an ID table and an image data storage area, said image data being recorded in said image data storage area, and position information of said image data recorded in said image data storage area being stored in relation to said ID in said ID table;
a terminal unit for outputting said image data recorded into said plurality of image data recorders,wherein when said ID is input in said terminal unit, said image data is output from one of said plurality of image data recorders to said terminal unit in response to said ID;
a load balancer having a load factor table, coupled with said plurality of image data recorders, for selecting one of said plurality of said image data recorders on the basis of the load factor of said load factor table to output said image data,wherein said load factor relates to a number of command applied from said terminal unit.

11. A method for recording and reproducing image data, said method comprising the steps of:
-
generating a plurality of image data; adding an ID to each of said plurality of image data, wherein said ID relates to a video frame and each ID added to each of said image data is different from each other; recording said image data with said ID added into a plurality of image data recorders, wherein said ID and said image data to which said ID is added are recorded into all of the plurality of image data recorders, respectively, wherein each of said plurality of image data recorders has an ID table and an image data storage area, said image data being recorded in said image data storage area, and position information of said image data recorded in said image data storage area being stored in relation to said ID in said ID table; and reproducing from said image data recorded into one of said plurality of image data recorders in response to said ID to command for a video replay; in the case of said command for a video replay, detecting the load factor of each of said plurality of image data recorders, and transferring said command for a video replay to one of said plurality of image data recorders based on the load factor of said plurality of image data recorders, wherein said load factor relates to a number of said command. - View Dependent Claims (12)
