摘要： Provided is a broadcast signal transmitting method including: generating a first bitstream including encoding information about data; generating a second bitstream by adding zero bits to the first bitstream, based on a difference between a modem data rate and a codec data rate; generating a third bitstream by encoding the second bitstream by using zero padding information about the zero bits; and transmitting a carrier signal generated by modulating the third bitstream.

摘要： A receiving apparatus is provided. The receiving apparatus includes: a receiver configured to receive an input signal including a transmission frame which includes a bootstrap, a preamble, and a payload; a bootstrap detector configured to detect the bootstrap based on a correlation between the input signal and a reference signal which is pre-stored; and a signal processor configured to signal-process the preamble based on the detected bootstrap and signal-process the payload based on the signal-processed preamble, and the bootstrap detector is configured to determine the correlation by quantizing at least one of the input signal and the reference signal and then multiplexing the input signal and the reference signal at least one of which is quantized. Accordingly, an area occupied by hardware and cost can be reduced and loss of performance can be minimized.

摘要： A transmitting apparatus is provided. The transmitting apparatus includes: an L1 signaling generator configured to generate L1 signaling including first information and second information; a frame generator configured to generate a frame including a payload including a plurality of sub frames; and a signal processor configured to insert a preamble including the L1 signaling in the frame and transmit the frame. The first information includes information required for decoding a first sub frame among the plurality of sub frames. Therefore, a processing delay in a receiving apparatus is reduced.
