Title: Look-up table based approach for layer combining in ISDB-T and ISDB-TSB receivers

Abstract: A method of layer combining based on generating a look-up table in an Integrated Services Digital Broadcasting (ISDB) receiver includes obtaining a transmission parameter configuration, generating the look-up table based on the transmission parameter configuration, assembling a null transport stream packets and a valid transport stream packets from a plurality of layers of a multiplexing frame, and generating a completed transport packet stream using the look-up table. The receiver may generate the look-up table by at least one of generating the look-up table in real time or selecting from a look-up table set based on the transmission parameter configuration. The transmission parameter configuration may include at least one of a transmission mode, a guard interval, a modulation, and a coding rate. The look-up table may define an order of the null transport stream packets and the valid transport stream packets from the plurality of layers in the multiplexing frame.
