Abstract
The present invention proposes a method for providing a broadcast content in an apparatus, the method comprising: requesting a filter code to an application running on the apparatus by using a first Application Programming Interface (API); receiving a JavaScript Object Notation (JSON) object from the application in response to the first API; storing the filter code; receiving an Extended File Delivery Table (EFDT) having a first filter code associated with a first file; and selectively downloading the first file by comparing the stored filter code with the first filter code in the EFDT.
Claims10
A method for providing a broadcast content in an apparatus, the method comprising:
- requesting a filter code by using a first Application Programming Interface (API), wherein the filter code is an integer associated with personalization categories as determined by a broadcaster;
- receiving an object in response to the first API, wherein the object includes the filter code and expiration information for indicating an expiry of the filter code;
- storing the filter code;
- receiving a Distribution Window Description (DWD) including information for indicating a distribution window during which a first file will be delivered and a first filter code associated with the first file, wherein the first filter code represents a personalization description for the first file and wherein the filter code is unique within a scope of an application context identifier for identifying an application context;
- and
- selectively downloading the first file during the distribution window by comparing the stored filter code with the first filter code in the DWD.
An apparatus for providing a broadcast content, comprising:
- a storage;
- a processor configured to request a filter code by using a first Application Programming Interface (API), wherein the filter code is an integer associated with personalization categories as determined by a broadcaster,
- wherein the processor is further configured to receive an object in response to the first API, wherein the object includes the filter code and expiration information for indicating an expiry of the filter code, and
- wherein the processor is further configured to store the filter code in the storage;
- and
- a receiver configured to receive a Distribution Window Description (DWD) including information for indicating a distribution window during which a first file will be delivered and a first filter code associated with the first file, wherein the first filter code represents a personalization description for the first file and wherein the filter code is unique within a scope of an application context identifier for identifying an application context, and
- wherein the receiver is further configured to selectively download the first file during the distribution window by comparing the stored filter code with the first filter code in the DWD.
