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.
