Abstract
A method of viewing a content item is provided. The method includes receiving an encrypted content item and a network address of a key management system from a primary client device over a communications network. A session key is obtained over the communications network and the primary client device is notified that the session key has been obtained. An encrypted version of a content key is received over the communication network to decrypt the content item and content rights that determine access to the content item. The content rights restrict the content item from being rendered unless it is rendered in coordination with the rendering of the content item by the primary client device. The encrypted version of a content key is decrypted with the session key. The content item is rendered in accordance with the content rights by decrypting the content item with the content key.
