Title:
BROADCAST SIGNAL TRANSMISSION DEVICE, BROADCAST SIGNAL RECEPTION DEVICE, BROADCAST SIGNAL TRANSMISSION METHOD, AND BROADCAST SIGNAL RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/117281
Kind Code:
A1
Abstract:
A broadcast signal reception device comprises: a demodulation unit for receiving a broadcast signal including a signal frame divided into a bootstrap area, a preamble area, and a data area, and demodulating the received broadcast signal in an OFDM scheme; a frame parsing unit for parsing the signal frame from the demodulated broadcast signal; an L1 signaling processing unit for processing preamble data received in the preamble area of the parsed signal frame to extract L1 signaling data including time information; a PLP data processing unit for processing PLP data of at least one PLP received in the data area of the parsed signal frame to extract at least one data packet; a container encapsulation unit for encapsulating the at least one extracted data packet into at least one container, and outputting the encapsulated data packet; a control unit for storing, in a memory, the extracted time information and time tick information for identifying a time point when the time information is extracted, if the at least one container is identified as a container that does not support time information transmission; and a system-on-chip unit for reading time information and time tick information stored in the memory, and controlling system decoding.
