Abstract: A method of processing additional information related to an announced service or content in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver includes receiving a service map table (SMT) and a first descriptor through a service signaling channel, identifying an image identifier and an image type of an image for an NRT service based upon the first descriptor, receiving the image via a flute session and displaying the image when corresponding service is played, wherein the image is logo or icon data for the NRT service. The method may further include connecting a service signaling channel, parsing the received SMT and the first descriptor, determining whether a service is the NRT service based upon the parsed SMT and storing the received image.

Abstract: A digital broadcasting system and a method of processing data are disclosed. A receiving system of the digital broadcasting system may include a signal receiving unit, a demodulating unit, a demultiplexer, and an audio/video decoder. The signal receiving unit receives a broadcast signal including main service data and an RS frame including a plurality of MPH service data packets.
