Distributing digital cinema package (DCP) over internet
Disclosed are systems, methods, and non-transitory computer-readable media for distributed DCP over internet. A client-side digital content delivery device receives a digital cinema package (DCP) for a digital movie from a remote digital content delivery system. The DCP includes a unique digital watermark applied by the content delivery system. In response to receiving an input to cause playback of the digital movie, the client-side digital content delivery device compares a unique device identifier for a display device paired to the client-side digital content delivery device to an authorized unique identifier. If the unique device identifier matches the authorized unique identifier, the client-side digital content delivery device uses the DCP to causes presentation of the digital movie by the display device paired to the client-side digital content delivery device.
