A system and method for secure delivery and playback of content at a theater complex domain. The domain receives encrypted and compressed content from a studio domain. The theater complex domain comprises at least a projection unit operable to render decompressed digital video content, and a security module removably coupled to the projection unit. The security module includes at least a decompression unit operable to produce decompressed digital video content. The security module further includes a decryption unit coupled to the decompression unit that is operable to produce unencrypted compressed digital video content that is then processed by the decompression unit. The security module further includes a watermark unit coupled to the decompression unit operable to produce the decompressed digital video content rendered by the projection unit that includes a watermark embedded therein. The watermark is used to identify uniquely the projection unit to which the security module is removably coupled, or alternatively, to identify uniquely the security module itself. The security module is physically locked in a tamper resistant container, and is preferably physically locked inside or onto the projection unit. A receiver is also coupled to the security module. |
