Transmitting system and method of processing digital broadcast signal in transmitting system, receiving system and method of receiving digital broadcast signal in receiving system
Methods and apparatus for transmitting and receiving broadcast signals are provided. The method for transmitting a broadcast signal includes encoding mobile data for forward error correction (FEC), encoding signaling data, forming data groups including the encoded mobile data and the encoded signaling data and transmitting a signal frame that includes the data groups.
1. A method for receiving a broadcast signal, the method comprising;
receiving a broadcast signal including first signaling data, second signaling data and service data of a service, the service data is carried by collections of data streams;
demodulating the broadcast signal;
decoding the first signaling data including first information for identifying one of the collections of the data streams,
wherein the identified collection includes a service signaling channel carrying the second signaling data for the service, the second signaling data providing service acquisition information for the service,
wherein the service signaling channel is a dedicated channel identified by pre-assigned value; and
decoding the service data by using the second signaling data,
wherein the second signaling data includes second information for identifying the identified collection, and third information for identifying data streams carrying the service data of the service within the identified collection.
2. The method of claim 1 ,
wherein the first information in the first signaling data and the second information in the second signaling data have the same values.
3. The method of claim 1 ,
wherein the second signaling data includes name information of the service.
4. The method of claim 1 ,
wherein the third information includes source IP addresses and destination IP addresses for the data streams carrying the service data of the service.
5. An apparatus for transmitting a broadcast signal, the apparatus comprising;
a processor configured to generate first signaling data, second signaling data and service data of a service, the service data is carried by collections of data streams,
wherein the first signaling data including first information for identifying one of the collections of the data streams,
wherein the identified collection includes a service signaling channel carrying the second signaling data for the service, the second signaling data providing service acquisition information for the service,
wherein the service signaling channel is a dedicated channel identified by pre-assigned value,
wherein the processor is further configured to encode the first signaling data, the second signaling data and the service data, and to generate a broadcast signal including the encoded first signaling data, the encoded second signaling data and the encoded service data; and
a transmitter configured to transmit the broadcast signal,
wherein the second signaling data includes second information for identifying the identified collection, and third information for identifying data streams carrying the service data of the service within the identified collection.
6. The apparatus of claim 5 ,
wherein the first information in the first signaling data and the second information in the second signaling data have the same values.
7. The apparatus of claim 5 ,
wherein the second signaling data includes name information of the service.
8. The apparatus of claim 5 ,
wherein the third information includes source IP addresses and destination IP addresses for the data streams carrying the service data of the service.
