摘要：
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.
