| Zusammenfassung: | The present invention relates to a video processing apparatus that includes: a signal receiver receiving an encrypted video signal which contains access rights information of a transmitting side and decryption information; an information extractor extracting the access rights information of the transmitting side and the decryption information from the video signal; an encryption processor decrypting the encrypted video signal based on the decryption information; an access rights information storage unit storing access rights information of a receiving side; and a controller sending the decryption information to the encryption processor if it is determined that the access rights information of the transmitting side matches the access rights information of the receiving side. Accordingly, the video processing apparatus and method processes access rights with respect to a video signal that is granted only to an authorized user, with a high degree of reliability. |
