Abstract:
1. A digital broadcasting transmitter for transmitting orthogonal frequency division multiplexing (OFDM) signals through a broadcasting network having a plurality of transmission channels, the OFDM signals being obtained by modulating a plurality of transport streams, the digital broadcasting transmitter comprising: a transmitting device which transmits the OFDM signals in a connected transmission in the broadcasting network, wherein-an the OFDM signals comprising a plurality of OFDM segments including OFDM symbols generated in a time base direction for the plurality of transmission channels and multiplexed in a frequency direction, the plurality of OFDM segments multiplexed in the frequency direction and processed with a simultaneous Inverse Fast Fourier Transform (IFFT) to generate the OFDM signals; and the transmitting device further transmitting control information, the control information including information concerning a physical configuration of a transport stream supplied by the broadcasting network and the features of the broadcasting network, wherein the control information further includes a connected transmission descriptor for coordinating the plurality of transmission channels subject to the connected transmission, the connected transmission descriptor comprising:
