A method for processing a stream of a digital broadcast receiver is provided. The method which processes a stream that is divided into a first area allocated to first mobile data and a second area allocated to normal data, includes: receiving a transport stream including new mobile data in at least a part of the second area separately from the first mobile data, demodulating the transport stream, equalizing the demodulated transport stream, and decoding at least one of the first mobile data and the new mobile data from the equalized transport stream. Accordingly, mobile data services may be provided in various ways.
