Abstract: A movie antipirating scheme associates a detector with a screen and takes video and/or pictures of the audience. The detector can either detect something emitted by the camera or can find an image of a camera in the audience. An output indicative of the location of the probable camera can be used to find the person using the camera in the audience. Eg by detecting his seat number if sitting down or location if the camera has been stashed somewhere.

Abstract: An implicit address structure and technique are disclosed for rapidly accessing storage registers by eliminating the need for generating a separate address before referencing the register. A structure is provided for generating an address composed of parameters which are incorporated into the contents of the storage register. At the same time that the address generation occurs, the structure of the present invention provides an associative compare of the implicit registers, and if there is a match, the address generation step is terminated and the data is immediately available from the implicit register.
