Copy Control Information

Copy Control Information (or CCI) is a two byte flag included in digital television streams that allows content owners to specify how content can be duplicated.

Originally defined as part of the 5C copy protection specification devised by DTCP working group back in 1998, it was later defined as part of the FCCs Plug and Play agreement in 2003.

The two most popular flags used are Copy Freely and Copy Once. Copy Freely is essentially no flag at all, while Copy Once means that a DVR can make one copy, but no more copies can be made. The best examples of these in use are in regards to the TiVo HD and Windows Media Center. A show that is marked Copy Once can not be transferred to another TiVo via the Multi-Room Viewing feature and can not be transferred to the computer via TiVoToGo. In regards to Windows Media Center, shows marked Copy Once can only be played on the same PC in which they were recorded and the directly connected to an Extenders for Media Center like the Xbox 360 -- ATI Digital Cable Tuner must be running firmware 1.19.12 or Copy Freely is treated like Copy Once.

0x00 - Copy freely - Content is not copy protected.

0x01 - Copy No More - Essentially the same as 0x02

0x02 - Copy Once - A recording can be made, but that is it.

0x03 - Copy Never - the content can be recorded and viewed for 90 minutes after transmission, and is not transferable.

0x04 - Content is Copy Once for digital output, but would have Macrovision 7 Day Unlimited restriction applied on the analog outputs. This affects content viewed either on an HDTV with component cabling or on a standard definition TV. It also affects content saved to VCR or DVD when the recorder is connected to an analog output on the DVR.

0x07 - Content is Copy Never for digital content (deleted after 90 minutes) and Macrovision 7 day/24 hour for content recorded from analog channels. Content cannot be transferred via TiVoToGo transfers or MRV, and cannot be saved to VCR or DVD.

The application of the CCI flag was specified on page 30 of the FCC Plug and Play agreement ^[2]. In the order it is specified that over-the-air broadcast television channels must be set to be Copy Freely and that non-premium subscription programming has to be set to at least Copy Once, but of course can be set to Copy Freely. This is determined by the cable television provider and can vary from one market to the next (even if both markets are served by the same company). Some operators tend to set all programs as Copy Once, preventing further distribution after a single PVR recording, and others tend to set all programs as Copy Freely.^[3]
