1-16. (canceled)
A method for transmitting a broadcast signal in a transmitter, comprising:
- generating service layer signaling (SLS) information for at least one broadcast service, wherein the at least one broadcast service corresponds to a real time service or a non-real time service;
- generating service list table (SLT) information, wherein the SLT information comprises information for discovery of the SLS information,
- wherein the SLS information includes both of Media Presentation Description (MPD) information associated with the real time service and metadata related to at least one application for the non-real time service;
- and
- transmitting the broadcast signal including both of the SLS information and the SLT information via a physical layer.
A broadcast signal transmitter, comprising:
- a memory configured to store data;
- a communication unit configured to transmit the broadcast signal;
- and
- a processor configured to control the memory and the communication unit,
- wherein the processor is further configured to:
- generate service layer signaling (SLS) information for at least one broadcast service, wherein the at least one broadcast service corresponds to a real time service or a non-real time service;
- generate service list table (SLT) information, wherein the SLT information comprises information for discovery of the SLS information, wherein the SLS information includes both of Media Presentation Description (MPD) information associated with the real time service and metadata related to at least one application for the non-real time service;
- and
- transmit the broadcast signal including both of the SLS information and the SLT information.
