Apparatus and method for controlling output of protected content on a television

摘要

An apparatus for a television includes storage areas for storing a key and authentication information, a communication unit to transmit and receive information from a server supplying protected content, and a controller to control output of the protected content from the server based on an authentication procedure. This procedure includes encrypting the stored authentication information with the key, transmitting the encrypted authentication information to the server, and then outputting the protected content received from the server for display after transmission of the encrypted authentication information if determined to be valid.

1. An apparatus for a television comprising:
a first storage area to store a key; a second storage area to store authentication information in an encrypted form; a transceiver to transmit a first signal requesting connection to a server through a network and to receive a second signal from the server requesting authentication information for the television; and a controller to control output of the protected content received from the server based on an authentication procedure, wherein the authentication procedure includes:
detection of the authentication information stored in the second storage area in the encrypted form,decryption of the detected authentication information stored in the encrypted form,encryption of the decrypted authentication information with the key,transmission of a third signal that includes the encrypted authentication information to the server,reception of a fourth signal requesting additional authentication information for authenticating the television from the server,encryption of the additional authentication information with the stored key,transmission of a fifth signal including the encrypted additional authentication information to the server, andoutputting the protected content received from the server for display after transmission of the fifth signal.
