Transmitting/receiving system and broadcast signal processing method

A method for transmitting a broadcast signal in a transmitting system, the method comprising:

• performing RS (Reed-Solomon) encoding and CRC (Cyclic Redundancy Check) encoding on an RS frame payload to build an RS frame and dividing the RS frame into multiple portions, wherein the RS frame payload is made up of at least one data packet having a packet header and a packet payload, wherein the packet header includes stuff indication information for indicating whether stuffing data are included in the at least one data packet, and wherein the packet payload includes at least broadcast service data and signaling data for a service;
• forming data groups including each of the multiple portions and adding known data sequences and transmission parameters to each data group;
• convolutional interleaving data of the data groups;
• trellis-encoding the convolutional interleaved data;
• and
• transmitting the broadcast signal including the trellis-encoded data, wherein the broadcast signal further includes information for a rapid service acquisition,
• wherein the information for the rapid service acquisition includes a first service identifier for identifying the service, first indication information for indicating whether the service is hidden, and protection indication information for indicating whether one or more components needed for presentation of the service are protected,
• wherein the signaling data include a second service identifier for identifying the service, second indication information for indicating whether the service is active or inactive, and component acquisition information associated with the service, and
• wherein the component acquisition information includes a destination IP (Internet Protocol) address and a destination UDP (User Datagram Protocol) port number for at least one component of the service.

A transmitting system for processing broadcast data, the transmitting system comprising:

• an encoder to encode data in a frame payload to generate a frame, wherein the frame payload is made up of at least one data packet having a packet header and a packet payload, wherein the packet header includes stuff indication information for indicating whether stuffing data are included in the at least one data packet, and wherein the packet payload includes at least broadcast service data and signaling data for a service;
• a first interleaver to block interleave the encoded data;
• a second interleaver to convolutional interleave the block interleaved data;
• a modulator to modulate the convolutional interleaved data;
• and
• a transmitting unit to transmit a broadcast signal including the modulated data,
• wherein the broadcast signal further includes information for a rapid service acquisition,
• wherein the information for the rapid service acquisition includes a first service identifier for identifying the service, first indication information for indicating whether the service is hidden, and protection indication information for indicating whether one or more components needed for presentation of the service are protected,
• wherein the signaling data include a second service identifier for identifying the service, second indication information for indicating whether the service is active or inactive, and component acquisition information associated with the service, and
• wherein the component acquisition information includes a destination IP (Internet Protocol) address and a destination UDP (User Datagram Protocol) port number for at least one component of the service.
