Method for processing a web service in an NRT service and a broadcast receiver
First Claim
1. A method of transmitting a Non Real Time (NRT) service via a broadcast channel, the method comprising:
- generating the NRT service and signaling data, the signaling data including an NRT Information Table (NRT-IT) describing one or more content items and a Service Map Table (SMT) containing service-level attributes for the NRT service, wherein the SMT includes information used as a linkage to the NRT-IT; and
transmitting the NRT service and the signaling data via a broadcast channel, wherein the signaling data is transmitted via a Service Signaling Channel (SSC) with a specific IP address and UDP port number,wherein the non-real time service includes one or more content items, each of the one or more content items composed of one or more files delivered via File Delivery over Unidirectional Transport (FLUTE) file delivery sessions,wherein, the NRT service is delivered within IP packets,wherein a service type of the NRT service includes at least one of a portal service and a push service,wherein the portal service is a type of the NRT service to browse an internet using a web browser,wherein each of the FLUTE file delivery sessions includes one or more FLUTE channels, and wherein the SMT describes one or more NRT services andwherein the NRT-IT provides descriptive metadata about the content items that make up the NRT service and includes information being used to map one or more files carried on the FLUTE file delivery sessions for the non-real time service to content items,wherein the NRT-IT includes information indicating a total size in bytes of the content items.

Abstract
A method of processing a web service in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing an NRT service in a broadcasting receiver may include receiving first signaling information, identifying whether a service type of an NRT service is a web service based upon the first signaling information, identifying a web page type and a web page version of the NRT service and browsing the NRT service. The method may further include connecting a service signaling channel, parsing the received first signaling information, determining whether the NRT service is supported in the broadcasting receiver and consuming the web contents of the NRT service. The NRT service may include at least one of a fixed NRT service and a mobile NRT service. The first signaling information may be a data casting description table (DDT) if the NRT service is the fixed NRT service. The first signaling information may be a service map table (SMT) if the NRT service is the mobile NRT service. The DDT may include a first field identifying the NRT service and a second field identifying a type of the NRT service. The type of the web service may include at least one of a web document of text HTML and a web document of CE-HTML. The third field and the fourth field may be valid if the type of the received service is the web service based upon the second field.
