    摘要： Secure content transfer systems and methods to operate the same are disclosed. Disclosed example systems include a client device for use at a physical location and a media server for use at the physical location. The example media server includes a security device to determine a first encryption secret based on a first encryption key and to determine a second encryption secret based on a second encryption key. The media server also includes a decrypter to decrypt received encrypted content for requested content based on the first encryption secret and an encrypter to re-encrypt the decrypted content data for the requested content based on the second encryption secret. In addition, the media server includes an interface to send the re-encrypted content data to the client device, wherein the client device is to decrypt the re-encrypted content data based on the second encryption secret to access the requested content.

    摘要： Secure content transfer systems and methods to operate the same are disclosed. An example system includes a content server to encrypt content according to an encryption key, and to transfer the encrypted content, the encryption key and a license to a client that supports a digital rights management technology. The example system further includes a broadcast system headend to determine the encryption key, wherein the broadcast system headend is physically separate from the content server, and a digital rights management license server to provide the license.

    摘要： A method and system for communicating text descriptive data has a receiving device that receives a data signal having text description data corresponding to a description of a video signal. A text-to-speech converter associated with the receiving device converts the text description data to a first audio signal. A display device in communication with the text-to-speech converter converts the first audio signal associated with the receiving device to an audible signal.
