Abstract: 86386969 Abstract A method of processing a broadcast signal that includes data of a Physical Layer Pipe (PLP) comprises frequency deinterleaving the data of the PLP, time deinterleaving the frequency- deinterleaved data, demapping the time-deinterleaved data, decoding the demapped data and processing a baseband frame in the decoded data to output a data stream including data packets. The baseband frame includes a header and a payload. The header comprises position information identifying a start position of a first data packet that begins in the baseband frame and identification information identifying whether another header is present in the header. A value of the position information is an offset from a beginning of the payload to a start of the first data packet that begins in the baseband frame. The other header includes type information for identifying a type of an extension field and length information identifying a length of the extension field. Date Recue/Date Received 2020-04-27

Abstract: A method of processing a broadcast signal that includes data of a Physical Layer Pipe (PLP) comprises demapping the data of the PLP, bit deinterleaving the demapped data, first decoding the bit-deinterleaved data and second decoding the first-decoded data. A baseband frame is processed in the second-decoded data to output a data stream including data packets. The baseband frame includes a header and a payload, with the header comprising position information with a length of 7 bits or 13 bits identifying a start position of a first data packet that begins in the baseband frame and identification information for identifying whether another header is present in the header. The other header includes type information with a length of 3 bits, identifying a type of an extension field and length information for identifying a length of the extension field.

Abstract: Disclosed herein is a method for sending a broadcast signal. The method includes formatting input streams into multiple data pipes (DPs). Formatting the input streams into the multiple DPs includes splitting the input streams into multiple data streams, deleting a null packet included in a data stream, and forming a baseband frame (BBF) by adding a header to the data stream. The baseband frame includes a deleted null packet (DNP) field indicative of the number of deleted null packets, and the DNP field comprises at least one of a first DNP or a second DNP.
