Apparatus for transmitting broadcast signals, apparatus for receiving broadcast signals, method for transmitting broadcast signals and method for receiving broadcast signals

摘要

Disclosed is a method for transmitting broadcast signals, including: formatting input streams to a plurality of data pipes (DPs), wherein the formatting comprises allocating data packets to a payload of a baseband frame (BBF), and adding a header indicating a format of the payload of the baseband frame, and the header comprises at least one of first control information and second control information.

主权项

1. A method for transmitting a broadcast signal, comprising:
formatting input stream into at least one physical layer pipe (PLP); encoding data of the at least one PLP; generating at least one signal frame by mapping the encoded data; and modulating the at least one signal frame using an orthogonal frequency division multiplexing (OFDM) scheme and transmitting the broadcast signal comprising the at least one modulated signal frame, wherein the formatting comprises mapping data packets to a payload of a baseband frame (BBF), and adding a header ahead of the payload, wherein the header comprises at least one of first control information or second control information, wherein the second control information comprises at least one of a second control information LSB (least significant bit) field or a second control information MSB (most significant bit) field, wherein the first control information indicates whether the second control information MSB (most significant bit) field is included or not, and wherein the value of the second control information is offset from the start of the payload to the start of the first data packet in the BBF, when the second control information MSB field is included, a first byte of the header consists of the first control information and the second control information LSB field and a second byte of the header consists of the second control information MSB field and at least one additional field.
