摘要:
An off-host audio engine interface exposes audio processing capabilities to a host. The interface receives offloaded audio streams and a host-processed audio stream from the host. The off-host audio engine processes the offloaded audio streams individually to create off-host-processed audio streams. The host-processed audio stream is mixed with the off-host-processed streams to create a mixed stream. The mixed stream undergoes audio processing by the off-host engine. The off-host audio engine provides output and reference audio streams based on the mixed audio stream. The reference stream can be provided to the host via the interface. Via the interface, the host can control local and global audio processing performed by the off-host engine by enabling or disabling local and global processing, and by enabling or disabling local and global audio processing components of the off-host audio engine.

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.
