1. LICENSES
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.
