Abstract
A digital broadcasting transmission system according to an embodiment, including a plurality of single program encoders configured to encode and multiplex respective single programs including video and audio signals and data signals, a PSIP generator configured to generate PSIP (program and system information protocol), the PSIP providing detailed information on video and audio broadcasting programs and data broadcasting programs to be multiplexed in the single program encoders, a multiple program multiplexer configured to multiplex a digital broadcasting stream transmitted from the plurality of signal program encoders and the PSIP transmitted from the PSIP generator, and a transmitter configured to transmit digital broadcasting signals multiplexed in the multiple program multiplexer. Further, the PSIP of the data broadcasting programs includes more detailed PSIP information in addition to a name of and show time of the digital broadcast programs such that when a selectable item associated with a respective broadcast program is selected, the more detailed PSIP information is displayed.
