A title key protection system includes a title key with recordable media content; storage in a repository is not required. The title key is decrypted when needed by a clearinghouse, and then re-encrypted. The title key confers rights from the content owners to the user to play and copy the content for personal use. A user downloads encrypted content from a content repository. The user's media recording device extracts an encrypted title key from the content and obtains a media key block and media ID from the physical media on which the content will be recorded. The encrypted title key, media key block, and media ID are transmitted to a clearinghouse. The clearinghouse decrypts the title key and derives a media unique key from the media key block and media ID. The clearinghouse re-encrypts the title key with the media unique key and returns this re-encrypted title key to the media recording device for recording with the content on the physical media.

The present invention provides a high brightness color selective light modulator (CSLM) formed by a polarization modulator positioned between two retarder stacks. The modulator changes the apparent orientation of one retarder stack relative to the other so that, in a first switching state of the modulator the two retarder stacks cooperate in filtering the spectrum of input light, and in a second switching state the two retarder stacks complement each other, yielding a neutral transmission spectrum. Two or more CSLM stages can be used in series, each stage providing independent control of a primary color. One preferred embodiment eliminates internal polarizers between CSLM stages, thereby providing an additive common-path full-color display with only two neutral polarizers. Hybrid filters can be made using the CSLMs of this invention, in combination with other active or passive filters. The CSLMs of this invention can be used in many applications, particularly in the areas of recording and displaying color images. They can be arranged in a multi pixel array by pixelating the active elements, and can be implemented as color filter arrays, using patterned passive retarders rather than active polarization modulators.
