Recently there has discussion regarding copy protection for television broadcasts , we wanted to provide some top level information on some of the various copy protection mechanisms that are used for television broadcasts and the affect on Windows Media Center.
The Broadcast Flag is only used for digital television and the United States Court of Appeals ruled that the FCC had exceeded its authority in creating the Broadcast Flag rule. More high level information on the Broadcast flag can be found here: http://en.wikipedia.org/wiki/Broadcast_flag. Windows Media Center does not enable or utilize the Broadcast Flag.
CGMS-A is a copy protection mechanism used in analog television signals. More high level information on CGMS-A can be found here: http://en.wikipedia.org/wiki/CGMS-A. Windows Media Center currently enables CGMS-A.
Last month, some Windows Media center users were prevented from recording one episode of “American Gladiators”. Those users received an error stating that the recording was prevented due to restrictions set by the broadcaster. This was triggered by the inadvertent use of the CGMS-A flag.
Microsoft is investigating ways to reduce this from occurring in the future and will keep the profesional installer community abreast of changes when they occur.
