Abstract: A receiving method for receiving a plurality of carriers and generating one or a plurality of streams. The method includes a first demodulating step of processing a first transmission signal and generating a first demodulation output; a second demodulating step of processing a second transmission signal different from the first transmission signal and generating a second demodulation output; a combining step of generating one stream based on the first demodulation output and the second demodulation output; a selecting step of selecting one among the first demodulation output and the one stream, and generating a selected stream; and a back-end processing step of generating an output for a display from the selected stream and the second demodulation output. In the selecting step, the first demodulation output is selected in a receiving mode in single channel transmission, and the one stream is selected in a receiving mode in multiple channel transmission.

Abstract: A method of transmitting a data signal in sync with a clock signal in a DTV receiver. The method includes performing demodulation processing and error correction processing on an input carrier wave and outputting signals resulting from these types of processing; acquiring a transport stream (TS) packet included in the signals; acquiring a variable-length packet included in the signals; and selecting either the TS packet or the variable-length packet and outputting the selected packet as the data signal, where to variable-length packet is either a type length value (TLV) packet or an Internet protocol (IP) packet.

Abstract: A receiving system of the present disclosure includes: a plurality of demodulators; an add-on generating one stream based on an output from each of the demodulators; a selector selecting and outputting one among an output from one of the demodulators, namely the demodulator, and the one stream from the add-on; and a back-end processor generating an output for a display based on an output from the selector and the other demodulators, namely the demodulators. The selector selects an output from the demodulator in a single channel transmission mode, and selects the stream from the add-on in a multiple channel transmission mode.
