Method for transmitting and receiving broadcast signals, and broadcast reception device using said method

摘要

Disclosed are a method and device for transmitting and receiving broadcast signals. The disclosed reception method comprises a step for extracting second program table information which indicates the association properties between a plurality of programs, the programs being obtained by using a broadcast stream which comprises at least one program, program table information which indicates the broadcast stream, and at least one broadcast service, from a received broadcast signal. The method further comprises a step for parsing the broadcast stream by using the extracted program table information; and a step for acquiring information about the groups to which the plurality of programs belong by using the extracted second program table information.

1. A method of transmitting a broadcast signal, comprising:
generating a broadcast stream including at least one program, program table information representing the broadcast stream, and additional information on the broadcast stream; constituting a stream including the broadcast stream and the program table information; and transmitting the constituted stream and the generated additional information, respectively, wherein the program table information comprises an Event Information Table (EIT) including information on a plurality of events and Non-Real-Time Information Table (NRT IT) including information on a content transmitted through Non-Real-Time (NRT) service, wherein the information on a plurality of events includes name of the event, wherein the EIT comprises link information for linking an event in the EIT to the additional information on the event, wherein the link information comprises a link type field which represents types of the additional information which is linked to the event in the EIT, wherein the link information comprises service id of the NRT service and content linkage identifying a content item, being transmitted through the NRT service, including the additional information, when the additional information is transmitted through the NRT service, wherein the link information comprises information representing the numerical value of the one or more links for receiving the one or more associated contents and one or more links, wherein one or more pieces of link information corresponding to the one or more links, respectively, wherein the service id matches an identifier for NRT service included in the NRT IT, and the content linkage matches a content linkage included in the NRT IT.
