A receiving apparatus of a digital broadcasting signal, said apparatus comprising: means for selecting a desired transmission channel from said received digital broadcasting; means for demodulating a transport stream which is transmitted by said selected transmission channel; extracting means for extracting a transport stream of a desired program from said demodulated transport stream; interface means for connection to a digital recording and reproducing apparatus, wherein said receiving apparatus is operable to output the extracted transport stream of a desired program to the digital recording and reproducing apparatus through the interface means for recording by the digital recording and reproducing apparatus, and to receive, from the digital recording and reproducing apparatus through the interface means, a recorded transport stream which is reproduced by the digital recording and reproducing apparatus; and discriminating means for discriminating whether or not the transport stream which is reproduced by said digital recording and reproducing apparatus and received through said interface means is a multiplexed transport stream in which a plurality of programs have been multiplexed, and means, responsive to a determination by said discriminating means that said reproduced transport stream is a multiplexed transport stream, for performing a predetermined process for the receiving apparatus to select one program from said multiplexed plurality of programs, wherein said receiving apparatus does, upon reception of a multiplexed transport stream from the digital recording and reproducing apparatus, not provide processes for user selection of a desired program from packets of the multiplexed plurality of programs comprised in the multiplexed transport stream; wherein said extracting means is configured to extract the selected program from the multiplexed plurality of programs. means for selecting a desired transmission channel from said received digital broadcasting; means for demodulating a transport stream which is transmitted by said selected transmission channel; extracting means for extracting a transport stream of a desired program from said demodulated transport stream; interface means for connection to a digital recording and reproducing apparatus, wherein said receiving apparatus is operable to output the extracted transport stream of a desired program to the digital recording and reproducing apparatus through the interface means for recording by the digital recording and reproducing apparatus, and to receive, from the digital recording and reproducing apparatus through the interface means, a recorded transport stream which is reproduced by the digital recording and reproducing apparatus; and discriminating means for discriminating whether or not the transport stream which is reproduced by said digital recording and reproducing apparatus and received through said interface means is a multiplexed transport stream in which a plurality of programs have been multiplexed, and means, responsive to a determination by said discriminating means that said reproduced transport stream is a multiplexed transport stream, for performing a predetermined process for the receiving apparatus to select one program from said multiplexed plurality of programs, wherein said receiving apparatus does, upon reception of a multiplexed transport stream from the digital recording and reproducing apparatus, not provide processes for user selection of a desired program from packets of the multiplexed plurality of programs comprised in the multiplexed transport stream; wherein said extracting means is configured to extract the selected program from the multiplexed plurality of programs.
