Abstract
The present invention is related to a method of processing a broadcast service in an apparatus. The method may comprise: receiving a broadcast signal; receiving, from an application running on the apparatus, a request based on a first Application Programming Interface (API); generating a first JavaScript Object Notation (JSON) object by including the URL for the requested OSN; and delivering, to the application, the first JSON object in response to the first API.
Claims14
A method of processing a broadcast service in an apparatus, the method comprising:
- receiving a broadcast signal including service data for the broadcast service, first signaling information and second signaling information,
- wherein the first signaling information to includes On Screen message Notification (OSN) which notifies to a receiver a preference of a broadcaster for the receiver to avoid obscuring a part of video images,
- wherein the OSN includes duration information for identifying a duration of KeepScreenClear information regarding keep screen clear status corresponding to on-screen text or visual information, flag information for identifying a status of the KeepScreenClear information and version information for identifying a version of the KeepScreenClear information, and
- wherein the second signaling information includes User Service Bundle Description (USBD) including service identification information for identifying the broadcast service and name information of the broadcast service;
- and
- decoding the broadcast signal.
