CCI is a bit-encoded value associated with specific media content. It is delivered in the ECM for a program and
describes the 

 that should be applied to the content. Because CCI provides only the level of

protection that should be applied, it is up to the various software components that receive CCI to implement an
appropriate content-protection method based on the CCI level they receive.

The software components responsible for implementing content protection have some control over the output
devices on various consumer equipment (VCRs and digital recording devices) and on service provider equipment
(DHCTs, CableCARD modules, or tru2way™ hosts). Because each output device, or output port, performs a
unique function and resides on equipment manufactured by diverse vendors, the industry uses a variety of

As the following broad examples show, user impact varies according to the output port to which a subscriber
connects when attempting to record content and how the program content is protected:

Analog recording: When subscribers attempt to view a content-protected program that was sent

® technology will distort the program so

that it will be unviewable.



Digital recording: When subscribers attempt to view a content-protected program that was sent from

a digital output port, the digital recording device that receives the content will behave as required based
on the 

 that the port uses.

Important: CCI is delivered in the ECM for a program. As a result, it may be applied to any encrypted source.
However, it cannot be applied to a clear source because clear sources do not require ECMs.
