Patent ID: 8837343

Claim:
A method of processing a digital broadcast signal including mobile service in a transmitter, the method comprising: encoding signaling information for mobile service data of the mobile service, the signaling information including first signaling data which includes transmission parameters and second signaling data which contains cross layer information between a physical layer and an upper layer; formatting a data group including known data, the first signaling data and the mobile service data; and transmitting the digital broadcast signal including data in the data group, wherein the mobile service in the digital broadcast signal is transmitted via a first transmission mode or a second transmission mode, wherein the first transmission mode is a mode in which the mobile service is transmitted while reserving at least 38 of 156 packets in a slot for main service and the second transmission mode is a mode in which the mobile service is transmitted while reserving fewer than 38 of the 156 packets in a slot for main service, wherein the slot is a basic time period for multiplexing of the mobile service data and main service data according to the first or second transmission mode, wherein the first signaling data includes slot indicating information identifying whether the slot is a slot for the first transmission mode or a slot for the second transmission mode, and wherein a portion of the first signaling data of a slot is used for signaling an adjacent slot in a parade, wherein the parade is a collection of data groups that have same Forward Error Correction (FEC) parameters.
