DP HDCP VERSION CONVERTER

摘要

A DisplayPort (DP) High-bandwidth Digital Content Protection (HDCP) version converter that converts an HDCP content protection version from input to output includes a receiver and a transmitter. The receiver receives a serial bit stream transmitted from an upstream device, and decrypts link symbols of the received serial bit stream by use of a decryption unit. The transmitter encrypts, by use of an encryption unit, the link symbols decrypted by the receiver, and converts the encrypted link symbols into a serial bit stream and transmits the serial bit stream to a downstream device. The receiver and the transmitter have the same link configuration.
