Contents provided apparatus providing contents to portable apparatus and method thereof

A device and a method for providing contents to a portable device are provided to enable an MSO to download/protect charged contents to the portable device at the same time by authenticating the portable device. An interface(190) receives an information request signal for requesting the contents from the portable device(200). An ID storing part(180) stores an authentication ID of the portable device. A controller(145) allows the interface to transfer the contents to the portable device if an ID stored in the received information request signal is identical with the authentication ID stored in the ID storing part. An authenticator(170) authenticates the charged contents downloaded from a content server by using the authentication ID stored in the ID storing part. An HDD(Hard Disk Drive)(160) stores the contents downloaded from the content server. The controller permits the interface to transfer the contents stored in the HDD to the portable device.
