Here, the encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in case of ATSC scheme and DVB-Service Information (DVB-SI) information in case of DVB scheme. The ATSC-PSIP information or the DVB-SI information may be information included in the above-described stream, i.e., the header (4 bytes) of the MPEG-2 TS.
