COPY CONTROL INFORMATION Clause Samples

COPY CONTROL INFORMATION. Copy control information (CCI) is passed from the Card to the Host across the data channel to inform the Host device of the level of copy protection required. The CCI is sent in the clear to the Host device, but the integrity of the information is maintained by authenticating the CCI using a simple protocol. The one-byte CCI field contains information that the Host uses to control copying of content. Two EMI bits control copying on Host digital outputs, two APS bits control copying on analog outputs, one bit as a Constrained Image Trigger, one bit as a Redistribution Control Trigger, and four two bits are reserved.
