    • The present invention relates to a method and an apparatus for delivering an NRT service or NRT content through a broadcast signal. According to one embodiment of the present invention, the method for processing the NRT broadcast service comprises the steps of: receiving a broadcast signal including an IP multicast stream transmitted through a particular Internet protocol (IP) address; parsing a service map table (SMT) for signaling a non-real-time (NRT) service from the IP multicast stream included in the received broadcast signal; parsing a language information descriptor indicative of language information of an element associated with the NRT service at the parsed service map table; parsing, in the parsed language information descriptor, a language type field indicative of the type of language used in the NRT service and an element type field indicative of the type of element associated with the NRT service; and identifying that the language indicated by the language type field is used in the element associated with the NRT service indicated by the parsed element type field, wherein said element type field identifies one of elements which are associated with the NRT service and include a caption element of the NRT service and a text element of the NRT service.
    • 本发明涉及通过广播信号传送NRT服务或NRT内容的方法和装置。 根据本发明的一个实施例,用于处理NRT广播服务的方法包括以下步骤:接收包括通过特定因特网协议(IP)地址发送的IP多播流的广播信号; 解析服务映射表(SMT),用于从包括在所接收的广播信号中的IP多播流中发信号通知非实时(NRT)服务; 解析在解析服务映射表处指示与NRT服务相关联的元素的语言信息的语言信息描述符; 在解析的语言信息描述符中解析指示NRT服务中使用的语言类型的语言类型字段和指示与NRT服务相关联的元素的类型的元素类型字段; 并且识别由所述语言类型字段指示的语言在与由所解析的元素类型字段指示的NRT服务相关联的元素中使用,其中所述元素类型字段标识与所述NRT服务相关联的元素之一并且包括字幕元素 的NRT服务和NRT服务的文本元素。
