Blacklist of DRM Clients restricted from accessing protected content

This blacklist specifies the Primetime DRM clients that cannot access protected content. You blacklist clients by client version and platform.
Example use case: In the event of a security breach, a newer version of the Primetime DRM client can be specified as the minimum version required for license acquisition and content playback. The license server checks that the Primetime DRM client making the license request meets the version requirements before issuing a license. The Primetime DRM client also checks the version in the license before playing content. This client check is required in the case of domains where a license may be transferred to another machine.
A Primetime DRM client version may be identified by the attributes specified in the following table:
