If the validity condition is not satisfied, the audio signal in which the user's position is not inserted may be transmitted to the encoding unit 250. If the validity condition is satisfied, the inserting unit 230 inserts the user's position into the audio signal, and the transmitting unit 240 can transmit the audio signal.

In another example, if the validity condition is satisfied, the position of the user may be inserted by the insertion unit 230 through a method of determining whether the position of the user is correct in step 606. [ The audio signal can then be transmitted.

FIG. 7 illustrates a method for determining whether the position of a user is correct according to an embodiment.

At step 702, the location of the user via the display of the transmitting device 110 may be mapped and displayed on the map. Then, the user can confirm his / her location mapped on the map. With the map mapped, the user can adjust his / her position.

In step 704, the transmitting apparatus 110 can receive a signal indicating whether or not to re-position. If the position is incorrect, the determination unit 220 can re-determine the position by the position recrystallization signal.

As another example, at step 706, the transmitting apparatus 110 can receive a selection signal of a positioning method. The selection unit can select the positioning method by the selection signal.

In step 708, the transmitting apparatus 110 can receive a signal indicating whether the insertion is acceptable or not, and the insertion or non-insertion can be finally determined. In step 710, the insertion unit 230 may insert the user's position into the audio signal by the insertion accept signal.

For example, a signal for determining whether a position is re-determined, a selection signal for a positioning method, or a signal indicating whether an insertion is acceptable or not may be input by touching an electronic pen or a finger through a display of the transmission device 110.

In method 700, steps 704 and 708 may or may not be included.
