Patent ID: 8593977

Claim:
A method of transmitting data, comprising: determining a data transmission priority for each of a plurality of data needed to continuously perform a task, that is currently performing, in an external device by using information relating to the plurality of data and information relating to a plurality of data transmission means, wherein the plurality of data transmission means includes a first transmission means comprising a mobile storage medium which can be removed from and attached to the external device and a second transmission means comprising a network; determining a transmission method for each of the plurality of data based on the determined data transmission priority, wherein the transmission method comprises one of transmitting data through the mobile storage medium and transmitting data through the network, wherein the determining a transmission method comprises compressing data having the data transmission priority that is below a threshold order; and transmitting each of the plurality of data to the external device through one of the plurality of data transmission means corresponding to the determined transmission method of the each data of the plurality of data, wherein the transmitting data comprises transmitting uncompressed data having the data transmission priority that is above the threshold order and the compressed data, wherein the information relating to the plurality of data transmission means comprises at least one of a size of a usable storage space and a data transmission speed and the information relating to the plurality of data needed to continuously perform a task comprises information relating to at least one of a task execution state, a communication state, an address allocation, and a task control, wherein the size of the usable storage space indicates usable capacity of the mobile storage medium, and wherein the transmitting data comprises transmitting data having the data transmission priority that is above a threshold order through the first transmission means of the plurality of transmission means and data having the data transmission priority that is below the threshold order through the second transmission means of the plurality of transmission means.
