7. A method of processing metadata of content, the method comprising:
-
checking whether an expiry date of metadata has elapsed by referring to metadata update information added to each of a plurality of fundamental units for storing multimedia data; transmitting a metadata update request to a contents provider each time metadata of which the metadata expiry date has elapsed is extracted; comparing a stored metadata updated value with a metadata updated value received from the contents provider; determining whether corresponding metadata is received based a result of the comparing; if it is determined the metadata is received, updating a last updated value of the metadata. - View Dependent Claims (8, 9, 10)
