a new cyber farm item is received the home server transmits the item to the electronic frame 100 in step s 317 the new cyber farm item is instantaneously displayed in the electronic frame 100 as a moving image in the basic cyber farm in step s 319 so that for example if the electronic frame 100 shows a cyber fish tank the user feels as if they are putting a real fish in a fish tank and if the electronic frame 100 shows a cyber deer farm the user feels as if they are giving food to real deer the processed result of the electronic frame 100 is transmitted from the home server of the home gateway 106 to the mobile terminal 101 in step s 321 the electronic frame 100 checks whether a new cyber farm item further exists in the mobile terminal 101 in step s 323 if a new cyber farm item does not exist the user determines whether to terminate management of the cyber farm in step s 325 and if the user determines to terminate the cyber farm the process ends if the user determines not to terminate management of the cyber farm the process returns to step s 313 and the cyber farm is managed if a further cyber farm new item exists at step s 323 the process returns to step s 315 and checks whether a signal indicating purchase of a new cyber farm item is received from the mobile terminal 101 fig8 is a display representation of an implementation of a cyber farm here a fish tank displayed in an electronic frame according to the present invention in a.
