Abstract
A method for transmitting a broadcast signal according to an embodiment of the present invention comprises generating service layer signaling information for discovery and acquisition of a broadcast service and a content component of the broadcast service; generating service list information including for service list building and discovery of the service layer signaling information; and physical layer processing of the service list information, service layer signaling information, and content component.
Claims20
A method for transmitting a broadcast signal, the method comprising:
- encoding service data for a service;
- encoding service list information for one or more services including the service;
- and
- transmitting the broadcast signal including the encoded service data and the encoded service list information,
- wherein the service list information includes first URL (Uniform Resource Locator) information for indicating a URL for acquiring first ESG (Electronic Service Guide) information or first service layer signaling information for all services when the first ESG information or the first service layer signaling information is available via a broadband, wherein the service list information further includes information for the service, and
- wherein the information for the service includes:
- service identification information for identifying the service,
- category information for indicating a type of the service,
- capability information for indicating a capability required for decoding and presenting the service data, and
- second URL information for indicating a URL for acquiring second ESG information or second service layer signaling information for the service when the second ESG information or the second service layer signaling information is available via the broadband.
