Methods and apparatus for mixing encrypted data with unencrypted data |
摘要 |
Methods and apparatus for mixing encrypted data with unencrypted data are disclosed. A disclosed system receives data from a first media source, such as DVD-Audio content, and encrypts the data from the first media source using a key stream to form an encrypted data stream. The disclosed system may separate the encrypted data stream into a plurality of encrypted data streams and may combine the plurality of encrypted data streams with an unencrypted data stream associated with a second media source to form a mixed data stream. The mixed data stream is formed without decrypting the plurality of encrypted data streams and is transmitted to hardware or a hardware driver.
