VS1053b Datasheet
3 DEFINITIONS
1 Licenses
MPEG Layer-3 audio decoding technology licensed from Fraunhofer IIS and Thomson.
Note: If you enable Layer I and Layer II decoding, you are liable for any patent issues
that may arise from using these formats. Joint licensing of MPEG 1.0 / 2.0 Layer III does not
cover all patents pertaining to layers I and II.
VS1053b contains WMA decoding technology from Microsoft.
This product is protected by certain intellectual property rights of Microsoft and cannot
be used or further distributed without a license from Microsoft.
VS1053b contains AAC technology (ISO/IEC 13818-7 and ISO/IEC 14496-3) which cannot be
used without a proper license from Via Licensing Corporation or individual patent holders.
VS1053b contains spectral band replication (SBR) and parametric stereo (PS) technologies
developed by Coding Technologies. Licensing of SBR is handled within MPEG4 through Via
Licensing Corporation. Licensing of PS is handled with Coding Technologies.
See http://www.codingtechnologies.com/licensing/aacplus.htm for more information.
To the best of our knowledge, if the end product does not play a specific format that otherwise
would require a customer license: MPEG 1.0/2.0 layers I and II, WMA, or AAC, the respective
license should not be required. Decoding of MPEG layers I and II are disabled by default,
and WMA and AAC format exclusion can be easily performed based on the contents of the
SCI_HDAT1 register. Also PS and SBR decoding can be separately disabled.
