ABSTRACT:
A packet based high bandwidth copy protection method is described that includes the following operations. Forming a number of data packets at a source device, encrypting selected ones of the data packets based upon a set of encryption values, transmitting the encrypted data packets from the source device to a sink device coupled thereto, decrypting the encrypted data packets based in part upon the encryption values, and accessing the decrypted data packets by the sink device.
