System and method for the assertion and identification of rights information in an analog video signal
First Claim
1. A method for processing an analog video signal that represents a work for which rights information is asserted, the signal includinga rights assertion mark (RAM) in the video portion of the signal within the visible picture such that capture of the picture will include the mark, andcopy control information (CCI) bits in the vertical blanking interval of the signal for representing copying and redistribution rules;
- comprising the steps of;
determining if the RAM and CCI bits are present in the work,if the RAM is present and the CCI bits are present, then applying the copying and redistribution rules represented by the CCI bits, andif the RAM is present but the CCI bits are not, then applying the most restrictive copying and redistribution rules that can be represented by the CCI bits;
wherein the CCI bits are represented as CGMS-A information, the most restrictive copying rule is “
copy never”
, and the most restrictive redistribution rule is “
no redistribution”

Abstract
A method for processing an analog video signal that represents a work for which rights information is asserted. The signal includes a rights assertion mark (RAM) in the video portion of the signal within the visible picture such that capture of the picture will include the mark. The signal also includes copy control information (CCI) bits in the vertical blanking interval of the signal for representing copying and redistribution rules. If the RAM is present and the CCI bits are present, then the copying and redistribution rules represented by the CCI bits are applied. If the RAM is present but the CCI bits are not, then the most restrictive copying and redistribution rules that can be represented by the CCI bits are applied.

9. A method for asserting and identifying rights information in a work represented by an analog video signal, comprising the steps of:
-
inserting a rights assertion mark (RAM) in the video portion of the signal within the visible picture such that capture of the picture will include the mark, and inserting copy control information (CCI) bits in the vertical blanking interval of the signal for representing copying and redistribution rules, wherein the CCI bits are represented as CGMS-A information, the most restrictive copying rule is “
copy never”
, and the most restrictive redistribution rule is “
no redistribution.”
,where the signal is to be processed by a device that operates on it as follows; (i) if the RAM is present and the CCI bits are present, then the copying and redistribution rules represented by the CCI bits are applied, and (ii) if the RAM is present but the CCI bits are not, then the most restrictive copying and redistribution rules that can be represented by the CCI bits are applied. - View Dependent Claims (10, 11, 12, 13)

14. A method for processing an analog video signal that represents a work for which rights information is asserted, the signal including
a rights assertion mark (RAM) presented by a Veil modulation of the video portion of the signal within the visible picture such that capture of the picture will include the mark, and copy control information (CCD) bits for representing copying rules, said CCI bits being represented as CGMS-A information in the vertical blanking interval of the analog signal; -
comprising the steps of; determining if the RAM and CCI bits are present in the work, if the RAM is present and the CCI bits are present, then applying the copying rules represented by the CCI bits, and if the RAM is present but the CCI bits are not, then applying default copying rules; wherein the video signal further includes secondary copy control information (SCCI) that conforms with the CCI bits, and if the RAM and SCCI bits are present but the CCI bits are not, then the copying and redistribution rules represented by the SCCI bits are applied. - View Dependent Claims (15, 16)

17. A method of controlling the processing of an analog video signal in a player device using Copy Control Information (CCI) rules, wherein said analog video signal includes CCI bits and a rights assertion mark (RAM) confirming the presence of CCI bits in the analog video signal, comprising the steps of:
-
checking said signal for said CCI bits and said RAM; if both are present then operating said device in accordance with said CCI bits; if said RAM is present but said CCI bits are absent then operating said device in a default mode; and if said CCI bits are absent, said device is operated in a mode in which said analog video signal cannot be redistributed. - View Dependent Claims (18, 19, 20, 21)
