Abstract

A receiving system and a data processing method are disclosed. The receiving system includes a receiving unit, a demodulator, a first handler, and a second handler. The receiving unit receives a broadcast signal including fast information channel (FIC) data, mobile service data, and a service signaling channel, the FIC data including a field indicating that a table signaling service guide bootstrap information to the service signaling channel is included therein, and the mobile service data and the service signaling channel are packetized into an RS frame belonging to a desired ensemble. The demodulator demodulates the received broadcast signal. The first handler acquires service guide bootstrap information from the table included in the service signaling channel. And, the second handler accesses a service guide announcement channel by using the service guide bootstrap information.

Claims

1. A method for processing a broadcast signal, the method comprising:

encoding service acquisition information, wherein the service acquisition information contains information for rapid broadcast service acquisition;

encoding signaling information including transmission parameters;

generating broadcast signal frames including the signaling information and the service acquisition information;

transmitting the broadcast signal including the broadcast signal frames,

wherein the broadcast signal further includes a service signaling element containing attributes for accessing the broadcast service and components of the broadcast service,

wherein the service signaling element includes location information specifying a source Internet Protocol (IP) address and a destination IP address of a session carrying the components, and first service identification information specifying the broadcast service,

wherein the service acquisition information includes second service identification information specifying the broadcast service,

wherein the first service identification information of the service signaling element has a value that is matched to a value of the second service identification of the service acquisition information, and

wherein the service acquisition information further includes version information indicating a change of a protocol for the service signaling element.

2. The method of claim 1,

wherein the broadcast signal further includes a guide access element describing service guide data services for broadcast services in the broadcast signal,

wherein the guide access element includes provider number information specifying a number of service guide providers.

3. The method of claim 2, wherein the guide access element further includes elements providing parameters necessary for bootstrapping a service guide.

4. The method of claim 3, wherein the service signaling element and guide access element are transmitted via a specific channel of which IP and UDP are predetermined in the broadcast signal.

5. An apparatus for processing a broadcast signal, the apparatus comprising:

a first signaling encoder that encodes service acquisition information, wherein the service acquisition information contains information for rapid broadcast service acquisition;

a second signaling encoder that encodes signaling information including transmission parameters;

a frame encoder that generates broadcast signal frames including the signaling information and the service acquisition information;

a transmission unit configured to transmit the broadcast signal including the broadcast signal frames,

wherein the broadcast signal further includes a service signaling element containing attributes for accessing the broadcast service and components of the broadcast service,

wherein the service signaling element includes location information specifying a source Internet Protocol (IP) address and a destination IP address of a session carrying the components, and first service identification information specifying the broadcast service,

wherein the service acquisition information includes second service identification information specifying the broadcast service,

wherein the first service identification information of the service signaling element has a value that is matched to a value of the second service identification of the service acquisition information, and

wherein the service acquisition information further include version information indicating a change of a protocol for the service signaling element.

6. The apparatus of claim 5,

wherein the broadcast signal further includes a guide access element describing service guide data services for broadcast services in the broadcast signal,

wherein the guide access element includes provider number information specifying a number of service guide providers.

7. The apparatus of claim 6, wherein the guide access element further includes elements providing parameters necessary for bootstrapping a service guide.

8. The apparatus of claim 7, wherein the service signaling element and guide access element are transmitted via a specific channel of which IP and UDP are predetermined in the broadcast signal.
