1. A method for transmitting digital broadcast signal, the method comprising:
- generating signaling data including a transmission parameter,wherein the transmission parameter includes a protocol version field identifying between a first transmission mode and a second transmission mode;
forming a data group including mobile service data and the signaling data;
forming mobile service data packets including the mobile service data and the signaling data in the data group,wherein the first transmission mode is a mode in which the mobile service data are transmitted while reserving greater than 118 packets out of 156 packets in a slot and a second transmission mode is a mode in which the mobile service data are transmitted while reserving less than or equal to 118 packets out of 156 packets in the slot; and
transmitting the digital broadcast signal including the data group,wherein the transmission parameter further includes a transmission parameter field indicating a number of mobile service data packets exceeding 118 in the data group of a data frame,wherein the data frame includes 5 consecutive sub frames, andwherein the sub frame includes 16 consecutive slots, the slot is a time period during which the data group is transmitted.
