ABSTRACT:
A method of searching for a broadcasting channel of a specific program in a digital multimedia broadcasting (DMB) receiving terminal. The method includes detecting a program number input by a user, determining whether particular bits in a header of a received transport stream (TS) packet are identical to fixed values for the particular bits in the header, if the particular bits in the header are identical to the fixed values for the particular bits in the header, determining whether particular bits in a payload of the TS packet are identical to fixed values for the particular bits in the payload, and if the particular bits in the payload are identical to the fixed values for the particular bits in the payload, determining that the TS packet has program map table (PMT) information, and analyzing the PMT information to detect a packet identifier (PID) of an audio/video packetized elementary stream (PES) constituting the specific program.
