Abstract

A broadcast service receiving method of a broadcast receiving device provided. The method includes: receiving a trigger including location information of a bookmark target object; extracting the location information of the bookmark target object from the trigger; receiving bookmark target object related information including bookmark signaling data by using the location information of the bookmark target object; extracting the bookmark signaling data from the bookmark target object related information; when the bookmark signaling data is extracted, displaying that a bookmark target object is able to be bookmarked; when a user input for bookmarking the bookmark target object is received, saving the location information of the bookmark target object; and displaying location information of a saved bookmark target object at a predetermined time.

Claims

1. A method for a broadcast transmitting device, comprising:

configuring transport packet for broadcast, wherein a header of a video stream includes digital TV closed Caption (DTV-CC)

transmitting the transport packet,

wherein the DTV-CC includes extended characters including Uniform Reference Indicator (URI) string and trigger information of an event for an application,

wherein the trigger information includes activation trigger information,

wherein the URI string is used for obtaining a parameter table that describes a segment of program,

wherein the parameter table includes protocol version element representing version number of the parameter table, id element representing the segment described by the parameter table,

and capability element representing capacity necessary for presenting the application,

wherein the parameter table includes live trigger element specifying information used for activation trigger information,

wherein the live trigger element includes URL element of a server providing the activation trigger information, delivery type element representing protocol for receiving updated activation trigger information, and poll period element representing a period for receiving activation trigger information,

wherein the parameter table includes an application element representing the application while the parameter table describes the segment,

wherein the application element includes content item element representing a content item including at least one data file that the application requires,

wherein the application element includes event element representing an event for the application,

wherein the application element includes appID element identifying the application within the segment described by the parameter table,

wherein the event element includes eventID element identifying the event for the application,

wherein the event for the application is referenced to the activation trigger information through a combination of the appID element and the eventID element.

2. The method of claim 1,

wherein the transport packet includes video or audio data,

wherein the information of an event for an application is delivered via a watermark, which is included in the video or audio data.

3. The method of claim 1,

wherein the event includes a service for a bookmark.
