What are the license terms and/or license fees for using Intel IPP samples?
Intel IPP samples are provided to show how to use Intel IPP functionality. Some of these samples illustrate the use of Intel IPP in implementing functionality defined by industry standards. These samples are not product-feature-complete codec solutions.
When products are built in accordance to industry standards, there is often intellectual-property licensing involved. Such industry standards are international standards promoted by various standards bodies, such as ISO, ITU-T, and other organizations. When companies produce products in accordance with industry standards, they must ensure that they secure the appropriate technology and intellectual property licensing from the standards bodies and other third parties. Intel IPP material provides pointers to the standards bodies. Industry-standard licensing is not provided as part of Intel IPP, nor is it provided with these example illustrations.
