FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a method/apparatus for transmitting and receiving a broadcast signal based on the DVB-C2 digital broadcast standard. The technical result is improved data transmission efficiency. Said technical result is achieved due to that the method of transmitting a broadcast signal includes: mapping header data bits to header data symbols and data bits to data symbols; assembling at least one data slice based on the data symbols; time-interleaving the data symbols on the data slice level in a suitable manner for a channel positioning system; assembling a signal frame based on the header data symbols and the data slice, wherein the header data symbols comprise level L1 signalling information for transmitting data slice signals; modulating the assembled signal frame via orthogonal frequency-division multiplexing; and transmitting the modulated signal frame.
EFFECT: used interleaving may enable to decode a user-requested service in a random position of the window of the tuner.
