Abstract:
1. An image data recording and reproducing system comprising: an image data input unit for inputting an image data; an ID generator coupled with said image data input unit, for generating an ID inserted into each of video frames of said image data from said image data input unit, wherein said ID is inserted to distinguish each of said video frames, and each ID inserted into each of said video frames, is different from each other; a transmission network coupled with said image data input unit, for transmitting each of said video frames with said each ID; a plurality of image data recorders coupled with said transmission network, to each of which each of said video frames with said ID is applied, wherein each of said video frames with said each ID is commonly recorded into the plurality of said image data recorders, respectively, and wherein each of said plurality of image data recorders has an ID table and an image data storage area, each of said video frames is recorded in said image data storage area, and position information of each of said video frames recorded in said image data storage area is stored in relation to said ID in said ID table; and a plurality of terminal units coupled to said transmission network, each of which output each of said video frames recorded into said plurality of image data recorders, wherein when said ID is input in a terminal unit of said terminal units, one of a plurality of said image data recorders is selected and the video frame relating to said ID is output from the selected one of said plurality of image data recorders to said terminal unit in response to said ID, wherein said terminal unit is able to output said video frame relating to said ID based on the ID in said ID table from any one of said plurality of said image data recorders whenever a command relating to said ID for a video replay is input into said terminal unit; a load balancer which detects a state of load of said image data recorders, said load balancer having a load factor table, coupled with said plurality of image data recorders, for selecting one of said plurality of image data recorders to output one of said video frames, wherein said one of said plurality of image data recorders selected is based on a load factor of said load factor table, and wherein said load factor relates to a number of command applied from said terminal units.
