A CSS License is required to use CSS technology, and to receive and/or use and/or distribute CSS enabled DVD product characterized as Schedule 1 and/or 2 product. For example, DVD CCA would consider a CSS enabled DVD chip as Schedule 1 or 2 product. Accordingly, a company must be a CSS Licensee to receive or use or distribute such product. A CSS License is not required for Schedule 3 product. Schedules 1, 2, and 3 are defined within the CSS license agreements.

A CSS License (and/or Associate License) is available through the DVD Copy Control Association (DVD CCA). As of December 15, 1999, all of the operations and missions of CSS technology were transferred from the Interim Licensing Organization (ILO) to DVD CCA. With the formation of DVD CCA, the interim CSS License was discontinued and superseded by the final CSS License. DVD CCA had superseded the ILO in providing this service to Content Providers, Information Technology companies and Consumer Electronics companies worldwide, and as such has assumed the responsibility as Licensor of CSS technology. LMI (License Management International, LLC) is an administrative services company handling CSS license administration on behalf of DVD CCA. Neither DVD CCA nor LMI can provide legal advice or engineering services.

The Annual Administration Fee per Functional Membership License category is USD $15,500 (Associate License is USD $5,200). The flat rate fee for the appropriate technical specification is USD $500 for each set of specifications applicable to a particular license category (excludes "Authoring Studio" and "DVD Disc Replicator" technical materials). No specifications are available to Assemblers, Resellers, and Integrated Product Manufacturers.
