ATRAC AD Support
||Equipment that supports ATRAC AD can
save audio data that was encrypted for
copyright protection on storage media
such as flash memory or a hard disk. Since
the CXD5070 includes decryption functions
for this encrypted data that was
stored by a device that supports ATRAC
AD, it can easily implement music data
Furthermore, equipment that supports
ATRAC AD and that can acquire audio
data from an audio data input terminal or
a disk drive can encrypt the acquired audio
data and store it on a recording device.
The CXD5070 includes both the key
generation function required for encryption
that conforms to MagicGate as well
as encryption functions and thus can
implement high-speed ripping.
ATRAC AD Support
Inter-device authentication functions
||When audio data is safely transmitted between
equipment that supports ATRAC
AD or over a connection with a PC on
which an application that supports
ATRAC AD has been installed, it is necessary
to verify and authenticate that the
connected device can be trusted.
The CXD5070 includes the necessary data
and key generation and protection functions
for this inter-device authentication.
This allows the CXD5070 to form safe
inter-device connection environments.
ATRAC CD Support
||It is necessary to decrypt data encrypted
in conformance with the MagicGate standard
to play back audio data recorded under
the ATRAC CD standard.
The CXD5070 includes functions for decrypting
this ATRAC CD encrypted data
and can easily implement embedded
ATRAC CD playback functions.
||The CXD5070 performs complex processing
internally using common interfaces,
minimal communication functions, and a
simple API and can support the implementation
of ATRAC AD equipment.
