A method and device to transmit data broadcasting contents and a method and device to receive data broadcasting contents allowing data broadcasting contents reflecting a preference of a user to be transmitted. The method of transmitting data broadcasting contents includes: receiving content preference information indicating a preference for a transmitted data broadcasting content from a user terminal through a back channel; determining priorities of broadcasting contents to be transmitted based on the content preference information; and transmitting data broadcasting contents based on the determined priorities. Accordingly, the receivers actively transmit a request reflecting preferences to a data broadcasting transmitting device, and therefore, appropriate and early receipt of information can be expected.
