    摘要: An analysis method configured to analyze original signals on an auxiliary channel of DisplayPort between a transmitter and at least one receiver, includes: receiving a first original signal of the original signals; dividing the first original signal to obtain a DPCD address and a first data; storing the first data according to the DPCD address; determining whether the first data is a redundant signal; when the first data is not the redundant signal, analyzing the first data; and displaying a topology of the at least one receiver. The operation of analyzing the first data includes generating the topology of the at least one receiver.

    摘要: 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.
