Abstract: The method and apparatus for broadcast signal transmission are provided. A method of adjusting points of time when output packets are to be provided, performed by a stream generation device which provides an output stream, including the output packets, to a decoding device, according to an embodiment may include obtaining a first output packet and a second output packet; assigning a first multiplexing time to the first output packet and assigning a second multiplexing time different from the first multiplexing time to the second output packet; and providing the first output packet and the second output packet in the output stream to the decoding device by multiplexing the first output packet and the second output packet on the basis of the first multiplexing time and the second multiplexing time.
