    • A digital broadcasting system and a method for transmitting and receiving digital broadcast signal are disclosed. The method for processing a digital broadcast signal comprises processing the digital broadcast signal in at least two transmission modes, wherein the processing comprises first processing for a first transmission mode comprising forming a data group including mobile service data and place holder data for main service data, an MPEG-2 header and non-systematic RS parity data, removing the place holder data for main service data and non-systematic RS parity data in the data group, replacing the place holder data for the MPEG-2 header with an MPEG-2 header having a packet ID of mobile service data packets, thereby forming and outputting 118 mobile service data packets including data in the data group, multiplexing the outputted mobile service data packets and 38 main service data packets. Second processing for a second transmission mode of the processing comprises forming a data group including mobile service data, forming and outputting M numbers of mobile service data packets including data in the data group, wherein the M is an integer equal to or greater than 118 and equal to or less than 156, multiplexing the outputted mobile service data packets and N numbers of main service data packets when the N is not zero, wherein a sum of the M and N is 156 and transmitting the first and second processed digital broadcast signal.
    • 公开了一种用于发送和接收数字广播信号的数字广播系统和方法。 用于处理数字广播信号的方法包括以至少两种传输模式处理数字广播信号,其中处理包括第一传输模式的第一处理,包括形成包括移动业务数据的数据组和主服务数据的占位符数据, MPEG-2报头和非系统RS奇偶校验数据,去除数据组中的主服务数据和非系统RS奇偶校验数据的占位符数据,用MPEG-2替换MPEG-2报头的占位符数据 头部具有移动业务数据分组的分组ID,从而形成和输出包括数据组中的数据的118个移动业务数据分组,多路复用输出的移动业务数据分组和38个主业务数据分组。 用于处理的第二传输模式的第二处理包括形成包括移动业务数据的数据组,形成并输出包括数据组中的数据的M个数量的移动业务数据分组,其中M是等于或大于118的整数,以及 等于或小于156,当N不为零时,多路复用输出的移动业务数据分组和N个主业务数据分组,其中M和N的和为156,并发送第一和第二处理的数字广播信号。

    • A method and an apparatus for processing digital broadcast signal are disclosed. The method of processing a digital broadcasting signal in a transmitter includes performing RS (Reed-Solomon) encoding on signaling data containing cross layer information between a physical layer and a upper layer, wherein the signaling data includes a first field indicating a protocol version change of the signaling data, a second field indicating a length of an extension field of a header included in the signaling data, and at least one field indicating a number of ensembles for at least one of a first transmission mode and a second transmission mode, and wherein the ensembles include a collection of services, each of the services being a package of packetized streams of mobile service data, forming data groups including the signaling data and the mobile service data, forming mobile service data packets including the signaling data and the mobile service data in the data groups, transmitting the digital broadcasting signal including the mobile service data packets during slots, 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 the slot and the 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.
