BROADCAST SIGNAL TRANSMISSION APPARATUS, BROADCAST SIGNAL RECEPTION APPARATUS, BROADCAST SIGNAL TRANSMISSION METHOD, AND BROADCAST SIGNAL RECEPTION METHOD

摘要

The present invention provides a method for transmitting a broadcast signal. The method for transmitting the broadcast signal according to the present invention may comprise the steps of: formatting input streams into multiple data pipes (DPs); encoding data of the multiple DPs according to a code rate for each DP; generating at least one signal frame by mapping the encoded data of the multiple DPs; and modulating data of the generated signal frame in an orthogonal frequency division multiplexing (OFDM) scheme, and transmitting the broadcast signal including data of the modulated signal frame.
