Theater identification system utilizing identifiers projected through a screen
First Claim
1. A method for marking a copy of an image sequence comprising the steps of:
- presenting the image sequence onto a screen; and
from a position located behind the screen, projecting through the screen at least one identifier distinct from the image sequence such that the identifier is displayed using visible light along with the presented image sequence;
wherein the projected at least one identifier represents marking data comprising a forward error correction code.

Abstract
A method and a system for identifying a copy of an image sequence which is presented on a screen. At least one identifier distinct from the image sequence can be projected through the screen such that the identifier is displayed using visible light along with the image sequence. The identifier can be presented at periodic intervals and can define a theater location, a date and/or a time. A color and/or an illumination of at least a portion of the image sequence presentation can be measured. Based on the measured illumination and/or color, a projection brightness and/or color can be determined for the identifier. Also, a location on the screen through which the identifier should be projected can be determined.
